Network protocols Running header NETWORK PROTOCOLS Network Protocols The Case of Huffman Trucking Team D Paul Bropleh 11 Will Mason Detricia Coardes Alexander Rodriguez and Michelle Walker University of Phoenix NTC 360 Stephen Omogbehin February 19 2007 Network protocols 2 Network protocols and their importance Protocols define the standards for communication between network devices Dean 2000 p 63 Protocols govern how networks communicate without the use of protocols data could not traverse a network because it would not know where to go or how to get to its destination The most commonly used protocols include TCPIP and IPXSPX Network security depends on the proper usage of protocols within the network structure Team D will examine the current state of the network topologies on Huffman s networks examine the reasoning behind using the current network protocols identify the various types of network protocols including the advantages and disadvantages of each and the recommendations for the updating of the protocols on the Huffman enterprise Identifying current protocols The current state of topologies used at Huffman Trucking includes the following two TCPIP a suite of subprotocols that operates at the Transport Internet and Application layers of the OSI model FTP operates at the Application layer TCP at the Transport Network layer and IP at the Internet layer of the model IPXSPX originally developed by Xerox and later adopted by Novell in its Netware network operating system IPX Intemetwork Packet Exchange is a connectionless protocol that does not guarantee reliable delivery similar to IP while SPX Sequence Packet Exchange assures that data is delivered without error similar to TCP The use of the two protocols throughout the Huffman chain of networks forms a multiprotocol network in which two or more protocols operate on the network at the same time The reason Network protocols that the network became this type of network is because the network is a legacy network and must be upgraded to become a wellestablished LAN Rationalizing the use of current protocols Huffman Trucking uses the different protocols because the various applications used at the different sites demanded different protocols Huffman realizes the use of more than one protocol can compromise network security and may not allow certain parts of the network to communicate with one another Advantages of protocols The following are the advantages of using the various protocols are as follows I TCPIP I Routable it carries network addressing information that can be interpreted by routers Dean 2000 p 65 I Supports all modern operating systems I Traffic controllers for large private networks I Connects dissimilar systems I Robust scalable crossplatform clientserver framework I IPXSPX I Fast and highly established I Works with TCPIP in newer versions I Enables file and printer sharing on Windows NOS I Good for small to medium network traffic I AppleTalk I Not restricted by naming conventions I Allows easy sharing of resources Disadvantages of protocols With the advantages of the protocols also come the disadvantages of the two major protocols These disadvantages are 3 Network protocols 4 I TCPIP I Flexibility which is an advantage is also a disadvantage because it requires significant configuration I Strict naming conventions and limited IP address availability I IPXSPX I Required to communicate with networks operating Netware 32 or lower I Extensive documentation required to track growing networks I Requires current version to communicate with TCPIP networks I Strict naming conventions hexadecimal I AppleTalk I Not suited or large LANs or WANs I Each node belongs to only one zone Both protocols require extensive configuration but TCPIP is a exible protocol that can be used to communicate with routers along a corporate network Our recommendations The extensive research of the various networking protocols gives us the confidence of recommending TCPIP as the protocol utilized throughout the Huffman network TCPIP is fast becoming the most popular network protocol because of its low cost and it ability to communicate between a multitude of dissimilar platforms It is a de facto standard on the Internet and is commonly the protocol of choice for LANs Configuration is extensive but can be offset by the use of Microsoft network operating systems such as Server 20002003 and XP Professional Network protocols 5 References Dean T 2000 Network Guide to Networks Cambridge MA Course Technology
