Abstract

This paper describes a pair of patterns that enhance the reuse, extensibility, and portability of object-oriented communication software by permittingnetwork services to evolve independently of the mechanisms used to establish connections used by the services. The Acceptor and Connector patterns decouple the passive and active establishment of a connection, respectively, from the service performed once the connection is established. In addition, the patterns decouple the service creation and concurrency strategies from the services themselves. 1 Introduction Connection-oriented protocols (such as TCP/IP or IPX/SPX) provide reliable delivery of data between two or more endpoints of communication. Establishing connections between endpoints involves the following two roles: ffl Passive role -- which initializes an endpoint of communication at a particular address and waits passively for the other endpoint(s) to connect with it; ffl Active role -- which actively initiates a connection t...
