| Number | Title | Issue Date |
| 7643467 | Source-implemented constraint based routing with source routed protocol data units Source-implemented constraint-based routing with source routing enables traffic engineering to be performed and reservations to be made within a domain without requiring constraint information and reservation information to be disseminated to all nodes in the domain... | 01/05/2010 |
| 7643451 | Method and apparatus for extending a mobile unit data path between access points Fast transitions between access points (APs) in a wireless network may be accomplished when a mobile unit (MU) moves between the APs, by causing a first tunnel to be established between the APs, and causing a second tunnel to be established between the new AP and th... | 01/05/2010 |
| 7643407 | Method and apparatus for determining protection transmission unit allocation Protection transmission unit allocation, such as STS# in a SONET/SDH network utilizing time slot interchange on the working path, may be determined by disseminating connection information, connection identification information, and a prioritization scheme, to nodes ... | 01/05/2010 |
| 7610332 | Overlay networks An overlay network includes a virtual content server for representing a content provider in a virtual content network and at least a client having a membership in the virtual content network and a content path between the virtual content server and the client. Each ... | 10/27/2009 |
