connector acceptor pattern

From where I can get link to con开发者_如何转开发nector acceptor pattern explained simple ,and also a sample code . The one I get cs.wustl.edu , I find difficult to understand.

In simple words; in a distributed system, once a service is initialized, this design pattern decouples connection establishment and service initialization. Acceptors, connectors, and service handlers helps in achieving the decoupling.

1> Connector establishes a connection with a remote acceptor component and initializes a service handler to process data exchanged after the connection is made.

2> Acceptor passively waits for connection requests from remote connectors, establishing a connection upon arrival of a request, and initializing a service handler to process data exchanged after the connection is made.

3> Initialized service handlers perform application-specific processing and communicate via the connection established by the connector and acceptor components.
