layers of the OSI model do WAN protocols operate? • What are some of these protocols? • On which OSI layers do switches and routers operate? • If routers reside at more than one layer‚ what is the difference between the OSI layers? Introduction: The OSI model was introduced in 1984. Although it was designed to be an abstract model‚ the OSI model remains a practical framework for today’s key network technologies like Ethernet and protocols like IP. The OSI model defines

Protocol A standard set of regulations and requirements that allow two electronic items to connect to and exchange information with one another. Protocols regulate data transmission among devices as well as within a network of linked devices through both error control and specifying which data compression method to use. In particular‚ protocols decide: the method of error checking‚ how to compact data (if required)‚ how

configured to manage access to subnet or network. ACL is a router firewall. It is applied on a router based on the three Ps‚ where one ACL can be configured as per interface‚ per direction and as per protocol. Per protocol configuration controls the flow of traffic on an interface. In this case each protocol must be defined to facilitate an interface. Per direction configuration wheels traffic in one direction at a go‚ on an interface. Per interface configuration controls interface traffic for instance

addresses and to create voluntary standards for the network. As local area networks became more pervasive‚ many hosts became gateways to local networks. A network layer to allow the interoperation of these networks was developed and called IP (Internet Protocol). Over time other groups created long haul IP based networks (NASA‚ NSF‚ states...). These nets‚ too‚ interoperate because of IP. The collection of all of these interoperating networks is the Internet. Two
