Package net.jini.jeri.tcp Description

Provides implementations of the Endpoint and ServerEndpoint abstractions that use TCP sockets as the underlying communication mechanism. Requests and responses are framed and multiplexed over TCP connections using the Jini extensible remote invocation (Jini ERI) multiplexing protocol.

A TcpEndpoint can be used to initiate requests over a TCP connection. Each instance contains a host name string (which may be a name or an IP address) and a TCP port number, as well as an optional SocketFactory for customizing the type of Socket instances to use. When initiating a new request, a new TCP connection is created to the host and port, using the socket factory if present, if an existing connection is not already available for use.

A TcpServerEndpoint can be used to listen for and receive incoming requests over a TCP connection. Each instance contains a TCP port number to listen on, a host name string to use in Endpoint instances derived from the instance, an optional ServerSocketFactory for customizing the type of ServerSocket instances to use, and an optional SocketFactory to use in derived Endpoint instances. When listening for requests, the port is bound to listen for TCP connections, using the server socket factory if present. The TcpServerEndpoint.enumerateListenEndpoints method will produce TcpEndpoint instances with the same host name, port, and client socket factory for client-side use (for example, to be embedded in remote proxies).

Jini ERI multiplexing protocol mapping

TcpEndpoint and TcpServerEndpoint map, respectively, OutboundRequest and InboundRequest instances to distinct sessions of a Jini ERI multiplexing protocol connection. For each new request initiated, a TcpEndpoint starts a new session as the client of a connection to the remote endpoint. As the server of an accepted connection, a TcpServerEndpoint creates a new InboundRequest to represent each session started by the remote endpoint. Request data is transmitted as the data sent for the corresponding session by the client, and response data is transmitted as the data sent for the corresponding session by the server. TCP connections are reused by a TcpEndpoint when possible.

Constraint support

TcpEndpoint and TcpServerEndpoint support the transport layer aspects of at least the following constraints: (Note that ClientMaxPrincipal, ClientMaxPrincipalType, ClientMinPrincipal, ClientMinPrincipalType, ServerMinPrincipal, DelegationAbsoluteTime, and DelegationRelativeTime constraints are trivially supported if ClientAuthentication.YES, ServerAuthentication.YES, and Delegation.YES are not supported.)
