摘要： A request to receive multicast data, associated with a multicast group, may be transmitted. The request may be transmitted via a tunnel. Group keys may be received in response to the request. The group keys may be based on the multicast group. An encapsulated packet may be received via another tunnel. The encapsulated packet may be processed, using the group keys, to obtain a multicast packet associated with the multicast data. The multicast packet may be forwarded to at least one multicast recipient.

摘要： Secure tunneled multicast transmission and reception through a network is provided. A join request may be received from a second tunnel endpoint, the join request indicating a multicast group to be joined. Group keys may be transmitted to the second tunnel endpoint, where the group keys are based at least on the multicast group. A packet received at the first tunnel endpoint may be cryptographically processed to generate an encapsulated payload. A header may be appended to the encapsulated payload to form an encapsulated packet, wherein the header includes information associated with the second tunnel endpoint. A tunnel may be established between the first tunnel endpoint and the second tunnel endpoint based on the appended header. The encapsulated packet may be transmitted through the tunnel to the second tunnel endpoint. The second tunnel endpoint may receive the encapsulated packet. Cryptographic processing of the encapsulated packet may reveal the packet having a second header. The packet may then be forwarded on an interface toward at least one multicast recipient identified in the second header.

摘要： A system establishes a virtual private network (VPN) tunnel to a destination and determines a next hop for the VPN tunnel. The system inserts the next hop, and an address associated with the destination, into an entry of a first table. The system inserts the next hop, and a tunnel identifier corresponding to the established VPN tunnel, into an entry of a second table. The system associates one or more security parameters, used to encrypt traffic sent via the VPN tunnel, with the tunnel identifier.

摘要： A network device implements congestion management of sessions of a network protocol. In one implementation, an incoming request component receives session requests for a negotiation session between the network device and a second network device. A capacity pool stores a value relating to capacity of the network device to continue to efficiently process the session requests. New sessions are initiated when the value stored in the capacity pool is less than an estimate of the capacity of the network device at which the network device maximizes processor usage while minimizing session timeouts.
