However, this needs a well-organized method of network switched communication to get entrance to the network expedients consistently and at an elevated switching rate. Additionally, to convene interactive network loads of fundamentally new switching ideas, diverse methods were developed to manage uniqueness of different traffics similar to data, voice and video. In voice communication, unequal breaks among diverse words are not suitable. As voice is time-receptive or else time-reliant traffic, synchronized and interactive services were necessary for the voice communication. In addition, the voice communication employs circuit switching method for network switching. BAD-IT is the uniqueness of network communication data. This word outlines that it is bursty, non-balanced, fragile, and tactless to the time. Bursty characteristic of network communication data and its autonomy to time specify a type of switching unusual to that employed in voice traffic. These produced the progress of packet switching network switching technique for data transfer (ElectronicsForU, 2010) & (Walter, Kuhm, Tutsch, Ludtke, & Zimmermann, 2010). So Circuit Switching is a network switching technique which entails the physical interlink of two systems. Additionally, a high-quality instance of circuit switching comprises the Public Switching Telephone Network. While Packet Switching is a network switching technique in which network switch transmits data packets among network destinations. Usually, this pertains to X.25 techniques, however this as well concerned to IPX/SPX and TCP/IP routers (Tampa Bay Interactive, Inc., 2004). In this new age of technology the development and availability of high speed internet and high capacity network establishment has posed lots of challenges. Under this circumstance, the main and prime challenge is to effectively manage the network traffic and quick switching among network nodes to offer enhanced user experience and support. However, to offer high data and processing based multimedia services, integrated management of data plus information composed of time-receptive and time-tactless data types needs a new and better networking framework that can effectively manage network data and its overall management. In this scenario this research will discuss and analyze high speed network switching design. This research proposal will describe the main principle and goals high speed network switching design. 2- Purpose Present IT and technology trends make it feasible to construct high data rate communication as well as collaboration networks that are competent to up-hold high performance at the distributed computing framework. The parallel processing designed on network through the product parts, like that individual computer systems, has achieved awareness like a significant parallel-computing atmosphere. In the majority of current workplaces and labs, there are 10s of PCs as well as terminals (SHINJI, et al., 2001; Anderson, Owicki, Saxe, & Thacker, 1993). The majority of company networks nowadays utilize switches to connect printers, computers and servers inside a building or else site. In this scenario, a switch works like a controller that allows networked devices to communicate each other proficiently. In the course of information distribution as well as resource allotment, switches set aside businesses currency and augment worker production (CISCO, 2010; Nash, 2000; Forouzan & Fegan, 2006). The network which we generally imagine is composed of a set of connections, switches and host arrangement controllers. Additionally, the data is inserted into the network by the manager in a transmitting system; besides negotiating a sequence of connections as well as switches, the data is sent to the controller at the host that is at the receiving end. Every connection is point-to-point, linking a single switch port to each a controller otherwise to the port of some further switch. In addition, the switches can be linked to every system and to the controllers in some physical layout of a network. However, the routing in the communication network is foundational upon the data surge, where a surge is a flow of units among a set of communicating hosts. There can be several flows among a specified couple of hosts, for instance by means of diverse performance assurances. Every unit is labeled by means of an identifier intended for its route. A routing table in every switch, constructed throughout network arrangement, decides the output port intended for every route. Moreover, all the units from a route obtain the similar track in the course of the network (Anderson, Owicki, Saxe, & Thacker, 1993; Kurose & Ross, 2009; Nash, 2000). This research proposal is about the “High Speed Network Switching”. Network Switching is one of the main techniques for the packet routing inside and outside of any network. With the immense increase in the network needs as well as technology of networks we are observing more and big web based applications those require higher data transfer rates for the efficient utilization. In this scenario high speed network switching is one of the prime needs of network functions. In the existing web based and other communication arrangements we cannot competently survive without proper high speed network switching technology. This research proposal is about one of the main aspects of high speed network switching which will be elaborated in the proceeding sections. 3- Problem Statement In establishing a high speed network switching at some network we can face a lot of problems as well as challenges. In any network there are various aspects regarding proper establishment of network speedy switching. In case of any network the switching is deferred through some of the major problems like transmission medium limitations, jitter, communication impurities and lots of other aspects. In this section I will outline some of the main problem areas that are in the way of achieving high speed network switching. In this age of technology and high speed communication, High-Speed Networks are experiencing two basic challenges intended for applicant network arrangements. Initially, the network communication and working structural design should be extendable by means of broadcast speeds. In this regard, the network transmissions in the visual area are able to utilize well-organized coding method and extremely elevated bandwidth speeds not obtainable in the present electronic technology. If the network structure depends upon electronic frame dealing out, it will bring in two major restrictions on the utmost back-to-back network communication throughput. The primary limitation is inherent in the reality that bit dealing out through electronic gates is presently less well-organized than communications of visually ciphered information. If ocular signals are transformed to electronics intended for recognition as well as processing, the majority of uninterrupted network competence will strike the usual electronic jump in its place the wanted ocular one. The next constraint is because of to the reality that networks have to service multiplexed data plus information flows produced as well as used through electronic devices at the network edge. If the multiplexed flows are exchanged by means of the extremely similar electronic technology within inside network contrivances, a little amount sources working at top speed can block the network. The perfect architecture should be made to function at traffic volumes a great deal bigger than what a single source can produce. Next, motions have to take place by means of severe QoS (Quality of Service) assurances. Applications require assurances in the back-to-back stoppage, bandwidth, jitter, etc. to offer their services. The perfect network structure must be firmly guaranteeing the agreed QoS restrictions. A lot of times similar assurance involve dealing most favorable resource utilization intended for finest service. For instance in a number of situations it is desired to misuse bandwidth on network communication mediums that necessitate severe QoS so as to assure smallest stoppage plus jitter (Florissi, Isochronets: a High-speed NetworkSwitching Architecture, 1995; Forouzan & Fegan, 2006). In this research I will discuss and analyze a new high speed High Speed Network Switching Architecture Isochronets with traditional Circuit Switching and Packet Switching network Architecture. The main research question of this thesis is: How High Speed Network Switching Architecture (like Isochronets) is better than traditional Network Switching Architectures like (Circuit Switching and Packet Switching). 4- Justification Isochronets are a new high speed network switching design that manages network as well as data traffic transfers in the network in due course, comparable to how green waves organize traffic motions in highways. In the concluding circumstances, synchronization is carried out in the course of coordinated traffic lights to produce routes intended for continuous as well as crash-free movement as of sender to the receiver. In Isochronets based new high speed network switching architecture, synchronization is achieved through facilitating a group of routes through erratic arrangement of network data transmission switches. Switches build routing communication trees, that is, paths as of the entire nodes to a certain target. A data frame is switched through chasing its course by means of an allowed tree. The synchronization method is known as Route Division Multiple Access (RDMA) since it splits network bandwidth in the middle of routing trees (Florissi, Isochronets: a High-speed NetworkSwitching Architecture, 1995).. In Route Division Multiple Access, the prime construct utilized to plan traffic movement is a time-band allocated to a routing tree. The time-band is a time period all through that network switches are organized to manage network traffic according to a specific routing tree. Throughout the time-band allocation, a frame sent out by a sender will broadcast along the routing tree to the target root. If no other traffic competes for the tree, it will go continuously. As well, middle nodes carry out no header processing. Numerous concurrent routing trees are able to plan network transmissions in similar (encompass concurrent time-band), as long as they do not allocate any connection in the similar path. Comparable to Circuit Switching (CS), time-band allots reticent network expedients (Florissi, Isochronets: a High-speed NetworkSwitching Architecture, 1995). Though, the components to that resources or expedients are assigned are neither point-to-point links, nor network data traffic bursts, however paths or routes. Routes stand for prolonged units as well as, therefore planning complications are capable to be determined ultimately balances a great deal longer than circuit slots. As well, routes are pre-assigned as well as not assigned on-require similar to circuits. Comparable to Packet Switching (PS), traffic inside a routing tree competes in favor of outward communication connections. Though, conflict is simply between frames to the similar ending target. As well, there is no argument intended for dealing out resources. The allotment of synchronized time bands to network routing trees and decision of frame collisions are the primeval constructs employed through RDMA to manage network data traffic movements as well as QoS (Florissi, Isochronets: a High-speed NetworkSwitching Architecture, 1995). 5- Research Questions In this research I will explore basically the two important research questions. Here are the two main research questions which will be explored all through this research thesis: 5.1- Question 1 Is present High Speed Network Switching Architecture (like Isochronets) suitable for establishment of High Speed Network? 5.2- Question 2 How new High Speed Network Switching Architecture (like Isochronets) is much better than traditional Network Switching Architectures like (Circuit Switching and Packet Switching)? (A comparative study). 6- Review of Literature In previous few years, numerous technology developments have joined to offer a chance for elevated performance and better distributed computing facility. Additionally, the developments in laser and fiber optic technology have determined and provided potential connection throughputs higher than a gigabit per second. The development along with high use of Dynamic RAM chips have turned out to be inexpensive enough to be cost efficient at offering the big amounts of buffering required at these tremendously high connection speeds. Furthermore, rapid routing as well as switching assessment is probable by means of present Complementary Metal Oxide Semi-conductor or CMOS technology (Anderson, Owicki, Saxe, & Thacker, 1993). In network arrangement, these developments make it possible to build a realistic local area network by means of numerous switches as well as gigabit per second point to point fiber connections constituted in a random networking design. This type of a network has numerous benefits. In distinction to networks similar to Ethernet that utilize a physical medium supported broadcast, or else networks similar to FDDI that is supported through the token ring technology and point-to-point networks present collective network bandwidth that is able to be a great deal bigger as compared to the throughput of an individual communication link, the capability to adjoin throughput increasingly through incorporating additional switches plus links to equalize workload necessities, the possibility intended for attaining lesser latency, together through condensing path spans as well as through removing the need to obtain control above the whole network previous to passing on, as well as a more supple technique to high accessibility by means of numerous unneeded conduits among hosts (Anderson, Owicki, Saxe, & Thacker, 1993). As I have mentioned above the new trends in technology along with the development of new systems are requiring better communication facilities as well as tools. In this scenario the traditional network designs reveals two major confines when serviceable with the High-Speed Networks: they do not level with network communication connection speeds as well as they do not properly up-hold the quality of service necessities by the extreme-performance application. The new Isochronets high-speed Networks architecture beats both confines. Isochronets examines network traffic and data frame motions over network links in resemblance to car movements on roads. In the end, traffic lights organize conflict at junctions. They are coordinated to produce a green signal of continuous movement. Isochronets achieve comparable continuous movement or motion through infrequent assessments of network switches to make uninterrupted or end-to-end routes in the network. Network data frames depart beside these facilitated routes necessitating no header processing at middle network switches (Florissi, Isochronets: a High-Speed Network Switching Architecture, 2010). A high performance communication network contains the power to transform the way or working of the distributed computing arrangement. Additionally, the short latency and the huge throughput communication permits a great deal faster combination of distributed systems than has been viable in the earlier period: by means of earlier generation networks, the extensive outlay of transmitting messages guided programmers to cautiously reduce the quantity of network data and information communication. Additionally, when united with these day’s powerful processors, quick networks are able to facilitate a new group of communication applications, like that desktop multimedia as well as utilization of a network of terminals like a supercomputer. A main obstacle to construct high performance networks is the complexity of speedy switching that is about obtaining the data coming on an input connection of a switch plus rapidly transmitting it out on the suitable output connection. The switching job is easy if the data is able to be dealt out in predetermined-length data cells. These cells are known as predetermined length data cells, switching engages in any case two diverse jobs. The initial is scheduling that is about deciding that which data cell to transmit all through every time slot, when other than single data cell is meant for the similar output. The next one is data forwarding, in this scenario sending the cell to the output one time it has been planned. A lot of high speed switch arrangements utilize the similar hardware intended for together scheduling as well as data forwarding. If the output plus input network connections of a switch are linked inside through a multi-phase interlink communication network, the inner network is able to notice as well as determine divergences among data cells as they work their path in the course of the switch. We assess that for high speed switching, together now as well as in the upcoming era; switch scheduling is able to gainfully be alienated as of data forwarding. Through performing this, the hardware intended for every job is able to be dedicated to the jobs. For the reason that cost of switch is governed through the visual parts required to make the fiber based communication connections, the additional cost of split hardware to perform scheduling is acceptable, mainly if communication connection exploitation is enhanced consequently. It is also assessed that available algorithms for bipartite toning are too slow to be utilized in a high speed network switch or else do not extensively plan the switch, forfeiting network data plus communication throughput (Anderson, Owicki, Saxe, & Thacker, 1993). 7- Type of study Qualitative research is all about discovering matters, considering observable facts, and resolving the problems. As all the organizations are engaged in research, qualitative study takes place in almost every office and study location, almost every day (QSR International Pty Ltd, 2007). In my research on High Speed Network Switching, I will use the Qualitative research technique. In this scenario I will analyze the literature along with network areas for the performance assessment and comparison of the traditional switching techniques (Circuit Switching and Packet Switching network Architecture) with the current and more enhanced High Speed Network Switching like Isochronets Architecture. In this scenario I will analyze some of the main areas of the network for the assessment of positive factors of the High Speed Network Switching like Isochronets Architecture and how this switching technology can offer superior facilities functionality for building better and up to date high speed network data transmission or communication (FHI, 2010). By using qualitative research technique we will be able to investigate the answers of the main question and methodically utilize a pre-definite collection of measures to respond this research question. Here we will gather verification and construct answers that were not assessed beforehand. Here we will also create answers that are appropriate further than the instant limits of the exploration. Here the use of qualitative research will be able to allocate these traits as well, to look for the answers and recognize the specified research dilemma or subject from the viewpoints of the limited people it engages. So the use of qualitative research is mainly efficient in getting more subject specific information regarding the ethics, deeds, attitudes as well as communal backgrounds (FHI, 2010). 8- Procedure In our research for High Speed Network Switching Architecture (like Isochronets) we will use some of the specific procedures for the overall assessment and comparison of the traditional network switching architectures like circuit switching and packet switching.

These will consist of prime problems which are being faced at present day high speed networks in case of managing high data transfer rates. 8.3- New technology Assessment In this phase we will discuss and analyze the available erudite on the high speed network switching Architecture. In this scenario we will assess main needs or requirements of such network. This will involve the deep and comprehensive study of some of the important areas and issues of these network technologies. 8.4- Isochronets technology Analysis This section of research will comprise a deep analysis of some of the main aspects of the Isochronets high speed network switching Architecture. Here we will analyze its major qualities and functionalities designed for managing and handling the high speed network data transmission.

Here we will determine the advantages that the new technology has offered on the traditional network communication arrangement. This will also engage assessment of both the technology areas and specification of excellent one. 8.6- Final Assessment This will be the final part of the research and will include a more thorough assessment of some of the main areas of both the technology platforms we have assessed for network switching. Here I will conclude the overall discussion and provide our decisive findings which I have discovered in this overall research. This will conclude the overall research in a more compact manner. 9- Statistical Analysis In case of this research project we are also aimed to perform some statistical analysis for supporting our research. In this scenario we will perform this research analysis on a number of network and communication factors. These factors will be explained below. The main intention of this research is to compare and assess the performance of one network with traditional network switching techniques as well as how these techniques can be improved by implementing new high speed network switching techniques. This will be based on some qualities of data in addition to bandwidth that will be compared and assessed through some statistical method and by means of some sort of graphical representation. 9.1- Data Factors to be assessed Below I have presented some of the data factors those will be assessed for analyzing the new technology based high speed switching technique application at any network: Network Bandwidth Packet Size Connection Speed Transmission Importees Line losses The qualities stated above will be assessed and evaluated for the better performance analysis among the traditional and new network switching methods. These variables are not ultimate we can reduce or else increase their quantities. In this regard we can as well add more performance assessment variables for much better analysis of the systems working and performance. 10- Conclusion In scenario of Network Switching Architecture there is always a dire need of constant improvement. This is because that we are having a very speedy developments and improvements in the network arrangements. Additionally, the speed and performance of network structures is improving day by day. In this scenario we definitely need some new and up to date methods and techniques. This research is also a new initiative for the analysis of needs and requirement for a modern high speed network data transmission and communication structures. In this scenario I will analyze: how high speed network switching architecture (like isochronets) is better than traditional network switching architectures like circuit switching and packet switching. This research will be a comparative study of different networking techniques and tools. 11- References Anderson, T. E., Owicki, S. S., Saxe, J. B., & Thacker, C. P. (1993).
