摘要： A system and method detects and responds to failures occurring in a virtual switch. The virtual switch is formed from two or more physical switches interconnected by a Virtual Switch Link (VSL). One physical switch is elected the Master, and it executes a link aggregation protocol for the virtual switch. If the VSL fails, one of the other physical switches assumes that it should become the Master for the virtual switch, and it begins executing the link aggregation protocol. By adding information unique to the physical switches in the control packets of the link aggregation protocol, remote switches can identify when the VSL fails, and report this condition to the original Master. In response, the original Master or the new Master takes corrective action.

摘要： In one embodiment, a first port of a device provides connectivity to a customer network and a second port of the device provides connectivity to a provider network. Frame mapping logic associated with the first port processes a network message received at the first port and accesses a Virtual Local Area Network (VLAN) mapping data structure that maps customer VLAN designations used in the customer network to provider VLAN designations used in the provider network. Frame mapping logic uses the VLAN mapping data structure to associate the received network message with a particular provider VLAN designation based upon the received network message's particular customer VLAN designation. The received network message is then passed toward the second port.

摘要： A system and method assures the proper and continued operation of intermediate network devices, such as bridges, in a computer network. The bridge includes a spanning tree protocol (STP) engine, which is configured to have a bridge assurance (BA) sub-engine. The STP engine assigns the bridge's ports to one of a Root, Alternate, Designated or Backup Role. The BA sub-engine directs the STP engine to issue configuration messages from all ports to which neighboring bridges are coupled, including ports assigned to the Root and Alternate roles. The BA sub-engine further looks for the receipt of BPDU messages from neighboring bridges and employs one or more timers to determine whether the neighboring bridges are continuing to operate properly.

摘要： The present invention provides improved unicast routing, multicast routing and unicast load sharing as compared with conventional methods. Preferred implementations of the invention provide improvements to IEEE 802.1Q. According to preferred aspects of the invention, each bridge is the root of its own multiple spanning tree instance (“MSTI”). Preferred implementations of the invention require no learning of media access control (“MAC”) addresses on the backbone of a network. Some methods of the invention can resolve spanning tree asymmetries. Preferred implementations of the invention require a very low computational load for control protocols.

摘要： A technique efficiently manages bandwidth (BW) for multipoint-to-multipoint (MP2MP) services in a provider network of a computer network. According to the novel technique, each bridge having a user-network interface (UNI) port of an MP2MP service generates a registration for the service that carries maximum BW values for each port direction (e.g., for each {service, priority, color} triple), e.g., as defined by a Service Level Agreement (SLA). The registrations are advertised among neighboring bridges throughout the network toward other UNI ports of the MP2MP service. As each bridge receives registrations from each neighboring bridge (or from the UNI port), the bridge advertises registered BW values pertaining to a particular direction on a particular one of its ports that correspond to the sum of the BW values for that direction received on all of the other ports of the bridge, up to a maximum BW value (e.g., configured or physical) for the particular port. The actual BW required for allocation on an active port for each direction is the lower of either the registered value advertised from the port in a particular direction or the registered value received at the port in the opposite direction.

摘要： A system and method automatically configures the interfaces of an intermediate network device. A discovery process operating at the device detects the identity or type of network entities actually coupled to the device's interfaces. Utilizing the identity or type of detected entities, a look-up is performed to obtain a configuration macro specially defined for each detected network entity. The retrieved configuration macros are executed and applied at the respective interfaces. During operation, the intermediate network device continues to monitor the identity and type of entities actually coupled to its interfaces. If a change is detected, such as an entity moving from a first to a second interface, the specially defined configuration macro for that entity floats from the first to the second interface where it is executed and applied.
