Class GossipServer

public class GossipServer extends Object

Deprecated: Use GossipRouter instead

Maintains a cache of member addresses for each group. There are essentially 2 functions: get the members for a given group and register a new member for a given group. Clients have to periodically renew their registrations (like in JINI leasing), otherwise the cache will be cleaned periodically (oldest entries first).

The server should be running at a well-known port. This can be done by for example adding an entry to /etc/inetd.conf on UNIX systems, e.g. gossipsrv stream tcp nowait root /bin/start-gossip-server. gossipsrv has to be defined in /etc/services and start-gossip-server is a script which starts the GossipServer at the well-known port (define in /etc/services). The protocol between GossipServer and GossipClient consists of REGISTER_REQ, GET_MEMBERS_REQ and GET_MEMBERS_RSP protocol data units.

The server does not spawn a thread/request, but does all of its processing on the main thread. This should not be a problem as all requests are short-lived. However, the server would essentially cease processing requests if a telnet connected to it.

Requires JDK >= 1.3 due to the use of Timer
