ENCAPSULATING PROTOCOL FOR SESSION PERSISTENCE AND RELIABILITY

摘要

The invention relates to network communications. A first protocol that encapsulates a plurality of secondary protocols is used to communicate over a network. Use of the first protocol provides session persistence and a reliable connection between a client and a host service. In one embodiment of this aspect of the inventions,, a second connection is established between the first protocol service and a host service using one of the secondary protocols. Communication between the first protocol service and the host service occurs via one of the secondary protocols. In another embodiment, a plurality of second connections are established between the first protocol service and a plurality of host services using the plurality of the secondary protocols. Specifically, each of the plurality of second connections is established between the first protocol service and a different host service and each of the plurality of second connections is established using one of the plurality of secondary protocols. Communication between the first protocol service and the plurality of host services occurs over each of the plurality of second connections via one of the plurality of secondary protocols. In yet another embodiment, the first connection between the client and the first protocol service is established through an intermadiary node. The first protocol can be communicated over TCP/IP and the secondary protocol can be, for example, HTTP, RDP, ICA, FTP, Oscar or Telnet. Additionally, each virtual channel can include a plurality of protocol packets that enable remote access functionality.
