As technology scales, Systems-on-Chips (SoCs) are becoming increasingly complex and heterogeneous. One of the most important key issues that characterize such SoCs is the seamless mixing of numerous Intellectual Property (IP) cores performing different functions and operating at different clock frequencies. In just the last few years, Network-on-Chip (NoC) has emerged as a leading paradigm for the synthesis of multi-core SoCs [1]. The routing algorithm used in the interconnection communication NoC is the most crucial aspect that distinguishes various proposed NoC architectures [2], [3]. However, the use of VCs introduces some overhead in terms of both additional resources and mechanisms for their management [4].
Each IP core has two segments to operate in communication and computation modes separately [5]. On-chip packet switched interconnection architectures, called as NoCs, have been proposed as a solution for the communication challenges in these networks [6]. NoCs relate closely to interconnection networks for high-performance parallel computers with multiple processors, in which each processor is an individual chip.
A NoC is a group of routers and switches that are connected to each other on a point to point short link to provide a communication backbone of the IP cores of a SoC. The most common template that proposed for the communication of NoC is a 2-D mesh network topology where each resource is connected with a router [7]. In these networks, source nodes (an IP-Core), generate packets that include headers as well as data, then routers transfer them through connected links to destination nodes [8].
The wormhole (WH) switching technique proposed by Dally and Seitz [9] has been widely used in the interconnections such as [10], [11]. In the WH technique, a packet is divided into a series of fixed-size parts of data, called flits. Wormhole routing requires the least buffering (flits instead of packets) and allows low-latency communication. To avoid deadlocks among messages, multiple virtual channels (VC) are simulated on each physical link [12]. Each unidirectional virtual channel is realized by an independently managed pair of message buffers [13].
This paper presents a new routing algorithm for irregular mesh networks by base that enhances a previously proposed technique. The primary distinction between the previous method and the method presented in this paper is passing messages from ONs in the network. Simulation results show that utilization of network by e-xy and OAPR algorithm is worse than the improved one, i-xy. We have been simulated every three algorithms for 5% and 10% of oversized nodes with uniform and hotspot traffic.

Introduction The bus loosely defines as a digital path between resources and the processor of computer system. The bus provides an informational gateway or highway of wires, which allow binary signals to transmit to and from peripherals, memory, the central processing unit (CPU), and other components of a computer system. Due to these attributes, bus architecture divided into two major groups, frontside bus and peripheral bus. The frontside bus, also known as the system bus, facilitates all internal communication of binary signals from the CPU to memory and vice versa.
Assignment 1 EUP1501 60944080 WSIS target 1. Connect all villages with ICTs and establish community access point Information communication technology it is a powerful tool that attaches people to have access. Villages need to access ICTs connection simply because they need to educate themselves and understand how the system of ICTs works. They must have access to internet and Wi-Fi. “internet provides access to a number of communication serves including the World Wide Web and carries email, news, entertainment and data files” Partnership (2010).
3COM offers a wide variety of networking solutions. From Switches to Hubs to Gateways, 3COM is one of the frontrunners in the networking industry. In this comparison of Fast Ethernet Networks and Gigabit Ethernet Networks, before discussing the similarities with the various components and their respective operations, we must discuss the differences between the two.
Open Shortest Path First (OSPF) is a link-state routing protocol which uses link state routing algorithm for Internet Protocol (IP) networks.Using OSPF, th convergence of a network can be done in very few seconds, loop-free paths can be guaranteed and better load-sharing on external links can be achievd. Every change in the topology of the network is identified within seconds using OSPF and it instantaneously computes the “shortest path tree” for every route using “Dijkstra's algorithm” . For that reason, OSPF requires a router which have a more powerful processor and more memory than any other routing protocols which leads to more elect...
This memorandum will attempt to explain the Open Systems Interconnection Model, known more simply as the OSI Model. The OSI Model has seven levels, and these levels will be discussed in detail. Particular mention will be made to which level TCP/IP functions with the OSI Model.
Perhaps the most redundant, fault-tolerant of all network topologies is the mesh LAN. Each node is connected to every other node for a true point-to-point connection between every device on the network.
Next, the writer goes over the second type of network architecture - the TCP/IP reference model, the granddaddy of the wide area computer network. This architecture allows the connection of multiple networks seamlessly. The architecture is flexible and capable of running even if some of the subnet hardware is destroyed or non-functional as long as the source and destination machines are functioning. In a similar fashion to the OSI model, the TCP/IP model has layers as well. In this case, we have four layers: the link
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
The primary goal in routing multicast connections is to make efficient use of the network resources and to establish fast connections for data transmission. The network is often defined by a graph G(V,E) . Multicast routing protocols are been used in practical systems such as multicast backbone(M bone).M bone chooses the shortest path to each destination using the IP routing mechanism.Multicast routing in ATM Switch performs two basic functions such as switch and queuing.
When electronic devices transfer information to another electronic device, the devices need to know when data flow is beginning and ending. This is done with signals for synchronization.i
Computers in technological development demand more efficient networking. In a very short period it has changed the way we have looked at things since centuries. It is one industry that is going to shape our future for centuries to come Coming from a background of Electronics and Communication Engineering, I have developed an interest to probe into the area of Networking and Computer Networks. Hence I wish to do Masters in Computer Science (CS) as my major.
My mobile phone network coverage allows me to make a call wherever I want, and the call is never cut off by the network. Independent surveys show that it has the best signal quality with excellent call clarity. The network covers 99 percent of the population, and it has installed more transmitters than any other digital network company. They guarantee that they work the best; in fact, they will even add a free minute of talk time if the call is ever lost. International and off-peak calls are the cheapest in the area. The company has been voted number 1 in customer satisfaction for 5 years in a row.
Mesh networks are reliable, stable, and redundant. If a node can no longer operate, all the others are not affected as they can still communicate either directly or through one or more intermediate nodes. Mesh networks can be very expensive due to the large amount of cable and connections required.
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
