Enhanced Interior Gateway Routing Protocol
Enhanced Interior Gateway Routing Protocol is a distance vector routing protocol, where a router shares information with neighboring routers about the network in an autonomous system and shares only the information that neighboring routers don’t have instead of the whole message. It is an enhanced version of Interior Gateway Routing Protocol, both of them uses the same distant vector technology and the distance information within them is not changed.
EIGRP is also called as dynamic routing protocol as it lets router to share information with other routers whose EIGRP is correctly configured, which in turn reduces the network administrator’s workload, who don’t have veto to change the routing table manually. As IGRP doesn’t hold up to the changed design of the internet protocol that supports classless IPv4 addresses, it has been replaced by EIGRP.
Enhanced Interior Gateway Routing Protocol is modified in such a way that it lessens the router’s workload and the amount of data that is to be transmitted between the routers. Other than i...
The Unistep IRP Elexol EtherIO 24 Module is a network board that is integrated with features that allow multiple devices over the same network to communicate. This microcontroller was designed to be implemented as an addition to a larger network system; the multiple features and capabilities allow for various industrial and home applications. Ethernet is very common and used in most networks, which makes the IRP a great candidate for networking problems both at home and in the work field.
The routing protocols for UWSNs can be categorized into two classes according to the number of the sinks,which is the destination and the final
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.

An Open Shortest Path First (OSPF) protocol enhancement to save energy using Energy Aware Routing (EAR) strategy
Mobile communications has played a very important role in the economic and social development of most countries as shown in studies by the Broadband Commission. Increasing number of mobile users has given rise to the need of high speed, reliable and seamless network connectivity. With this high pace of innovations in smart mobile devices and applications, there is an ever increasing demand for better coverage and higher data rates. It is worth noting that most data traffic is generated indoors as in homes, offices or in other public hot spots like shopping malls, airports, stations etc.
Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
SLIP and PPP are two communication protocols which allow a computer connected to a server via a serial line (such as a modem) to become an actual node on the internet. This allows you to run network applications on your home computer directly. While SLIP and PPP are largely similar, there are some key differences. PPP is a newer protocol, better designed, and more acceptable to the sort of people who like to standardize protocol specifications.
The purpose of this paper is give a summary of the function and use of Routers in today’s information age. To cover the complete subject of routers and routing, would be beyond the scope of this research paper. However the basic definition of a router is “ A device used to connect networks of different types, such as those using different architectures and protocols. Routers work at the Network layer of the OSI model. This means they can switch and route packets across multiple networks. They do this by exchanging protocol-specific information between separate networks. Routers determine the best path for sending data and filter broadcast traffic to the local segment.”
...rely over unsecure internet. As dynamic spoke to spoke tunnels can be created, traffic does not have to travel every time through the hub, which reduces bandwidth utilization and the amount that CPU has to process. DMVPN can provide highly scalable and hierarchical topology support using phase 3. It is very useful when new branch site comes up, as there is no need to add the configuration on hub routers. Due to high throughput at hub router, DMVPN is ideal for VoIP, because VoIP requires low latency and higher throughput. However, DMVPN is exclusive to the Cisco and cannot be implemented on the non-Cisco routers, further, QOS policies cannot be configured for spoke to spoke tunnels. In spite of having few shortcomings, usefulness of DMVPN suppress its disadvantages, and it is the most cutting-edge tool that should be used to connect remote sites of an organization.
The project team has identified several issues with the current network infrastructure. The first is the availability and cost of token ring hardware. Ethernet is the dominant network topology and is included on many devices at no cost. Equipment with token ring interfaces can be found but are much more expensive. Another problem is that the current hardware is about 10 years old and is experiencing increased maintenance costs. Another problem is that the majority of the existing cable plant does not meet minimal category 5 standards.
In recent years, Mobile ad hoc network is used due to increasing number of mobile devices such as mobile phones, laptops, PDA etc., An ad hoc network consists of infrastructure based ad hoc network that depends on pre-constructed infrastructure made of fixed nodes and infrastructure less ad hoc network that does not depend on pre-existing infrastructure and it is dynamically cooperate with set of independent nodes. A Mobile ad hoc network is self-organized network without infrastructure connected by wireless links. Due to de-centralized infrastructure, a node can act both as router and host. The nodes can directly communicate each other within their transmission range otherwise the multi-hop network is needed. The mobile ad hoc network is widely used in day-to-day life such as military operations where an infrastructure is unknown to the soldiers. Web services like e-mail can be used for file transfer and it also used in multimedia applications. It is also used in disaster recovery such as earthquake, tsunamis etc. In MANET, the nodes are free to move, it will change its connection to other devices frequently. An important issue in MANET is routing between two nodes, due to the changing topology of the network. The routing protocol should be secure to protocol to protect against network attacks such as Black hole attack, worm hole attack, Dos attack, grey hole attack. Mostly AODV, DSR, DSDV are prone to the attacks. Research work concentrates in the field of routing and security. MANET has attacks in all the layers. In the physical layer jamming, intercept and eavesdrop attacks may occur. In the data link layer, traffic analysis, monitoring, disruption may occur. In the network layer, wormhole, black hole, byzantin...
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.
File Transfer Protocol (FTP) is an application layer protocol, which has the primary function of transferring data files between computers (Clark 2003). The protocol specification was originally developed in the early 1970s, and was published as RFC 114 in April 1971, by Abhay Bhushan. This occurred even before the Internet Protocol Suite – commonly known as TCP/IP or Transmission Control Protocol (TCP) and the Internet Protocol (IP) – was even established (Kozierok 2005).
Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).
