TAILIEUCHUNG - Ebook Communication systems principles using MATLAB R: Part 2

Part 2 book "Communication systems principles using MATLAB R" includes content: Internet protocols and packet delivery algorithms; quantization and coding; data transmission and integrity. | 269 4 Internet Protocols and Packet Delivery Algorithms Chapter Objectives This chapter examines the defined standards and methods for Internet data communications the protocols. This encompasses the data formats employed as well as the algorithms that operate on that data in order to facilitate data com- munication between physically separate devices. On completion of this chapter the reader should 1 Be able to define IP TCP and UDP the role of protocol layers and what functions they perform. 2 Be conversant with the key elements of each protocol such as IP addresses and TCP sockets. 3 Be able to explain potential pitfalls in networking such as congestion col- lapse and know the approaches used to mitigate these problems. 4 Be able to explain the principles of routing and calculate the shortest path in a routing graph. There is a vast range of detail concerning the Internet protocols that cannot be discussed in detail in one chapter the intent here is to explain the salient points and examine some important aspects in depth. In addition to Internet standard RFC documents a very approachable reference is Kozierok 2005 . Detailed explanations of the inner workings of TCP IP are given in Stevens 1994 while implementation details are covered in Wright and Stevens 1995a . Introduction Suppose we wish to connect a number of devices together for the purposes of exchanging data. What is the best way to do this What do we mean by best in this context We might want a system that uses the available infrastructure in the most efficient manner or can transmit with the highest possible data rate Communication Systems Principles Using MATLAB First Edition.
