    摘要: A network comprising a switch configured to learn a source address (SA) for a source node with a source port that receives a frame comprising the SA if the SA is not previously learned on another port and to subsequently forward any frame comprising a destination address (DA) for a destination node that matches the learned SA on the source port associated with the SA. A network comprising a switch configured to flood a frame received on a receiving port if the frame comprises a DA that is not previously learned on a source port and to distinguish the flooded frame from other forwarded frames by labeling the flooded frame, wherein the frame is flooded on a plurality of ports. A method comprising disabling a plurality of filtering database (FDB) entries that correspond to a plurality of addresses that are associated with a port, and sending the addresses in a control frame.

    摘要: A communications network, comprising a plurality of nodes supporting connection-oriented traffic and connectionless traffic, wherein management traffic between the nodes is propagated as connectionless traffic having a unique management traffic Virtual Local Area Network (VLAN) identifier (VID), and wherein at least one node is configured to perform a Link Layer Discovery Protocol (LLDP) exchange operation to enable detection of inconsistent provisioning of the Management VID in at least one node. Also disclosed is a communications network component, comprising logic that enables connection-oriented traffic and VLAN-based connectionless traffic, wherein the logic propagates management messages as VLAN-based connectionless traffic having a management VID, and wherein the logic enables detection of inconsistent management VIDs in a network.

    摘要: A method comprising receiving a data frame, encapsulating the received data frame into a reflected frame message (RFM) encapsulated frame, and if the received data frame causes the RFM encapsulated frame to exceed a maximum service data unit size, either the data frame is truncated or the data frame is split into two smaller frames and those two smaller frames are encapsulated by two separate RFM frames, wherein if a truncation flag is set to be true, the data frame is truncated to be encapsulated in one RFM.

    摘要: A data communications network includes a ring configured for spatial reuse, such as a resilient packet ring. A first bridge is coupled to the ring and to an end station such as an interworking bridge or router. A second bridge coupled to the ring learns an association between the first bridge and the end station by monitoring packets originated in the network by the end station and sent on the ring by the first bridge. The second bridge learns the association by obtaining an identifier of the first bridge and an address of the end station from received packets. When the second bridge receives packets destined for the end station, the packets are forwarded as broadcast transmissions on the ring if the association between the first bridge and the end station has not yet been learned, and are forwarded as unicast transmissions to the first bridge on the ring if the association between the first bridge and the end station has been learned.

    摘要: This invention defines a routing method which allows a determination of best paths from link weights in situations where these weights are not additive, but the characteristic of a concatenated path is determined mainly by single "bottleneck" links. To be compatible, the metric must be chosen from a specific set of metrics, called bottleneck metrics in this description. The new widest-path method has some characteristics in common with the known Dijkstra method for additive weights. Implementations in communication networks are disclosed which lead to new nodes, new networks and new network protocols.
