Protocol basics

Describe the basic purpose of a router – Computers that specialize in sending packets over the data network – They are responsible for interconnecting networks by selecting the best path for a packet to travel and forwarding packets to their destination Routers are the network center – Routers generally have 2 connections: • WAN connection (Connection to ISP) • LAN connection

Client's Functions Handle the user interface. Translate the user's request into the desired protocol. Send the request to the server. Wait for the server's response. Translate the response into "human-readable" results. Present the results to the user. Listen for a client's query. Process that query. Return the results back to the client.

We now begin our look at building protocols using the basic tools that we have discussed. The discussion in this lecture will focus on issues of key establishment and the associated notion of authentication These protocols are not real, but instead are meant to serve just as a high-level survey Later lectures will go into specific protocols and will uncover practical challenges faced when implementing these protocols

Regardless of their basic purpose, virtually all e-commerce sites rest on the same network structures, communication protocols, and Web standards. This infrastructure has been under development for over 30 years. This appendix briefly reviews the structures, protocols and standards underlying the millions of sites used to sell to, service, and chat with both customers and business partners. It also looks at the infrastructure of some newer network applications, including streaming media and peer-to-peer (P2P)....

Most routing protocols fall into one of two classes: distance vector or link state. The basics of distance vector routing protocols are examined here; the next section covers link state routing protocols. Most distance vector algorithms are based on the work done of R. E. Bellman, L. R. Ford, and D. R. Fulkerson, and for this reason occasionally are referred to as BellmanFord or FordFulkerson algorithms. A notable exception is EIGRP, which is based on an algorithm developed by J. J. Garcia Luna Aceves....
