  • Multi-protocol route policy specification language
    Patent number: 7388865
    Abstract: An extended Routing Policy Specification Language (RPSL) permits registry of independent routing policies for different Internet Protocol versions, while being compatible with existing RPSL. Address family identifiers (afis) for identifying a protocol version are inserted into attributes of objects that carry IP address prefixes. RPSL is also extended to permit separate handling of multicast routing policies in any protocol, by including subsequent address family indicators (safis).

  • Method and apparatus for connecting IPv6 devices through an IPv4 network using a tunneling protocol
    Patent number: 7321598
    Abstract: A tunnel setup protocol enables tunnel clients to set up IPv6-in-IPv4 networks to permit IPv6 nodes to communicate across the IPv4 network using IPv6 native packets. The tunnel setup protocol uses a control channel to negotiate tunnel configuration parameters and exchange tunnel configuration data between a tunnel client and a tunnel broker server. The tunnel setup is automatic, and migration to IPv6 is ameliorated.

  • Connecting IPv6 devices through IPv4 network and network address translator (NAT) using tunnel setup protocol
    Patent number: 7305481
    Abstract: A tunnel setup protocol enables tunnel clients to set up IPv6-in-IPv4 networks to permit IPv6 nodes to communicate across the IPv4 network using IPv6 native packets, even if the IPv4 network contains a Network Address Translation function. The tunnel setup protocol uses a control channel to negotiate tunnel configuration parameters and exchange tunnel configuration data between a tunnel client and a tunnel broker server. The tunnel setup is automatic, and migration to IPv6 is ameliorated.

  • METHOD AND APPARATUS FOR CONNECTING IPV4 DEVICES THROUGH AN IPV6 NETWORK USING A TUNNEL SETUP PROTOCOL
    Publication number: 20060248202
    Abstract: A tunnel setup protocol enables tunnel clients to set up IPv4-in-IPv6 tunnels to permit IPv4 nodes to communicate across the IPv6 network using IPv4 native packets. The tunnel setup protocol is a control channel for negotiating tunnel configuration parameters and exchanging tunnel configuration data between a tunnel client and a tunnel broker server. The tunnel setup is automatic, support of IPv4 nodes and networks in IPv6 networks is enabled, and support of IPv4 devices after migration to IPv6 is facilitated.
