BORDER GATEWAY PROTOCOL EXTENSION FOR THE HOST JOINING/LEAVING A VIRTUAL PRIVATE NETWORK

摘要

A method for performing an automatic join and leave function for either a host or network using Border Gateway Protocol (BGP) signaling, the method comprising, sending a BGP join request that indicates a request to join a virtual network, receiving a BGP join response that indicates either an acceptance or a rejection of the BGP join request, adding the host to the virtual network when the BGP join response accepts the BGP join request, sending a BGP leave request that indicates a request to leave the virtual network, receiving a BGP leave response that indicates either an acceptance or a rejection of the BGP leave request, and removing the host from the virtual network when the BGP leave response accepts the BGP leave request, wherein the BGP join request comprises a quality of service (QoS) requirement and a bandwidth requirement.
