Connection Management

An Ice communicator establishes connections automatically and transparently as a side effect of using proxies. There are well-defined rules that determine when a new connection is established. If necessary, you can influence connection management activities.

Connection management becomes increasingly important as network environments grow more complex. In particular, if you need to make callbacks from a server to a client through a firewall, you must use a bidirectional connection. In most cases, you can use a Glacier2 router to automatically take advantage of bidirectional connections. However, the Ice API also provides direct access to connections, allowing you to explicitly control establishment and closure of both unidirectional and bidirectional connections.

The discussion that follows assumes that you are familiar with proxies and endpoints.
