What is packet switching, and why is packet switching relevant to the Internet?

Instructions: This is an individual assignment. Use the blackboard to submit your word file with answers by 11:59 pm on the due date (no hard copies please). Late submissions will receive a zero grade. Start working on this early.

1. Business case: Analyze the following business case and provide your recommendations.

Big E. Bank

Nancy Smith is the director of network infrastructure for Big E. Bank (BEB). BEB has just purchased Ohio Bank (OB), a small regional bank that has 30 branches spread over Ohio. OB has a WAN connecting five cities, in which it has branches, to OBs main headquarters in Columbus. It has a series of MANs in those cities (MAN is a Metropolitan Area Network, which usually spans a city), which in turn connect to the LANs in each of the branches. The OB network is adequate but uses very different data link, network and transport protocols than those used by BEBs network. Smiths task is to connect OBs network with BEBs network. She has several alternatives. Alternative A is to leave the two networks separate but install a few devices in OBs headquarters to translate between the set of protocols used in the BEB network and those in the OB network so that messages can flow between the two networks. Alternative B is to replace all the WAN, MAN, and LAN network components in OBs entire network so that OB uses the same protocols as BEB and the two can freely communicate. Alternative C is to replace the devices in OBs WAN (and possibly the MANs) so that each city (or each branch, if the MANs are replaced as well) can communicate with the BEB network but leave the LANs in individual branches unchanged. In this case, the device connecting the MAN (or the branch) will translate between the OB protocols and the BEB protocols. Your job is to develop a short list of pros and cons for each alternative and make a recommendation.
