Comprehensive coverage of building TCP/IP Applications for the popular Windows "TM" Sockets protocol. -- Covers all server designs including multiservice, multiprotocol, and single-process concurrent servers. -- Provides a conceptual basis for client and server design that points out the similarities and differences among various client and server designs, the role of concurrency, and when to use each design. -- Features the most complete coverage of server technology, demonstrating how to apply advanced server technology to applications.This volume answers the question "How does one use TCP/IP?" -- focusing on the client-server paradigm, and examining algorithms for both the client and server components of a distributed program.It presents an implementation that illustrates each design and discusses techniques like application-level gateways and tunneling. The book also reviews several standard application protocols and uses them to illustrate the algorithms and implementation techniques.
