Abstract
A system for providing continuous connection between a client and a network during a session. The system comprises of a connection utility, which monitors a network session for an occurrence of a pre-defined event and/or condition. The system is particularly advantageous in scenarios where a session's connection is lost and the session has to be reconnected to the network. The system also finds applicability with several other types of events/conditions, including a connection break, a slow or congested connection or a change in the type of data being transmitted. When any one of the pre-defined events/conditions occur, the session is automatically routed from the present connection route to another connection route, and is completed on the other connection route. In order to complete the re-routing of the sessions, session information is cached on the client and the server. The session data is tagged with the original session ID. On the server, a special Client Key is stored for later retrieval, and on the client a special Server Key is stored. During the reconnect, the server uses its previously stored session data associated with the client key and previous session ID to regain …
