TCP/IP Application Layer 499TelnetTerminal emulation (Telnet) software provides the capability to remotely access another computer. It enables you to log in to an Internet host and execute commands. Telnet commonly is used for remote administration of server[r]

addresses. Either could have been chosen as the TCP/IP universal host identifiers. The decision was made to standardize on compact, binary addresses that make computations such as the selection of a route efficient. For now, we wi[r]

the remaining IP header fields. Does the strong interaction between UDP and IP violate our basic premise that layering reflects separation of functionality? Yes. UDP has been tightly integrated with the IP protocol. It is clearly a compr[r]

mine whether a destination can be reached, and router solicitation and advertisement messages that hosts use to dynamically maintain a default route. An ICMP message travels in the data area of an IP datagram and has three fixed-length fields at the begin- ning [r]

The key-stone-pathogen, Porphyromonas gingivalis associates not only with periodontal diseases but with a variety of other chronic diseases such as cancer. We previously reported an association between the presence of Porphyromonas gingivalis in esophageal squamous cell carcinoma (ESCC) and its prog[r]

IP routing. In a properly configured routing table, the next-hop address for each destination must be a computer within the same logical subnet as the sender. To understand the constraint, remember that each LIS is designed to operate like a single LA[r]

sign machine names throughout the global Internet. Second, because it uses a geo- graphically distributed set of servers to map names to addresses, the implementation of c- the name mapping mechanism provides a large scale example of the client-server[r]

IP addresses mentioned in Chapter 4 and the flexibility of the UDP/IP transport mechanism. We will also see how a server assigns an IP address to a computer automatically. Such assignment is especially important in environments that permit temp[r]
