Determining MAC state using sequence numbers in a distributed environment |
April 12, 2011 |
| A derived state value is calculated based on a plurality of component state values. As any of the plurality of component state values changes, the derived state value is recalculated. When sending information about a MAC address or other data between two components, the derived state val |

Routing frames in a trill network using service VLAN identifiers |
August 31, 2010 |
| Methods, apparatus, and products are disclosed for routing frames in a TRILL network using service VLAN identifiers by: receiving a frame from an ingress bridge node for transmission through the TRILL network to a destination node that connects to the TRILL network through an egress |

Multiprotocol label switching (MPLS) edge service extraction |
August 12, 2008 |
| A technique for managing network traffic is disclosed. According to the technique, a set of VLAN IDs is explicitly identified for use with a first service. The rest of the customer traffic is considered as part of a default service. Traffic that is received at a PE from a customer is |

Stateful failover protection among routers that provide load sharing using network address trans |
November 21, 2006 |
| Failure protection is provided between two routers that are actively implementing load sharing using network address translation. Failure protection is achieved by generating state information at the two routers and then exchanging the state information between the two routers so that |
