the current state of the socket and the underlying protocols being used. 22.13 Specifying A Queue Length For A Server One of the options that applies to sockets is used so frequently, a separate function has been dedicated to it. To understand how it arises, consider a server. The server creates a s[r]

want to compute. This is not so, as we will see later, when other general purpose protectionmethods are used. In this latter case, the resulting function is just an approximation of thefunction we would compute from the original data. At the same time, cryptographic toolsensure an optimal level of p[r]

It also covers how to use a variety of Cisco IOS Software source options, execute commands to load Cisco IOS Software onto the router, maintain backup files, and upgrade Cisco IOS Software. In addition,[r]

Hence, the two essentialcomponents of the MAC layer are: access protocols and scheduling techniques.These are also the main targets of this Chapter.The studies carried[r]

After an email is composed, the email client or Mail User Agent (MUA) sends the information to the SMTP host or Mail Transfer Agent (MTA). SMTP stands for Simple Mail Transfer Protocol and is the foundation for virtually all[r]

Preface One of the great protocols that has been inherited from the Internet is TCP/IP and this is being used as the open standard today for all network and communications systems. The reasons for this popularity are not hard to find. TCP/IP and Ethernet are truly open standards available to compet[r]

Task Force (IETF). First standard IEEE802.11 for wireless network was introduced in 1997. Thelatest standard is faster and applied for longer communication. Today, ad hoc networks areattractive and challenging topic of research due to its tremendous applications (Perkins, 2001).The most popular appl[r]
