摘要:
A system is disclosed, that provides dynamic bandwidth sharing among a plurality of client nodes, which share network link resources in a communication network. Upon receipt of a bandwidth adjustment request from a requesting client node, the system adjusts bandwidth when network link capacity meets the bandwidth adjustment request, or when total amount of bandwidth offered to trade by any peers of the requesting client node meets the bandwidth adjustment request.

摘要:
A network component comprising at least one processor configured to implement a method comprising transparently snooping a path control message comprising a first path identifier, wherein the path control message is sent between a plurality of routers and is not intended for the network component, analyzing a plurality of frames each comprising a second path identifier, and diverting at least some of the frames away from at least one of the routers, wherein the second path identifier in the diverted frames matches the first path identifier. Included is a method comprising configuring a bypass path by snooping a control frame comprising a label switched path (LSP) identifier, and routing a plurality of data frames associated with the LSP identifier to the bypass path without routing any subsequent control frames associated with the LSP identifier to the bypass path.

摘要:
An apparatus comprising a processor configured to implement a method comprising receiving a first data structure comprising a first virtual local area network identifier (VID) and a first forwarding type, comparing the first VID and a first forwarding type with a second VID and a second forwarding type in a second data structure, and reporting a misprovisioned data structure if the first VID is the same as the second VID and the first forwarding type is not the same as the second forwarding type. Also disclosed is a method comprising implementing a network protocol to forward provisioning information in a plurality of VID Tables corresponding to a plurality of nodes, and analyzing the provisioning information to detect misprovisioned nodes.
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:
An apparatus comprising a first interface configured to transmit or receive backbone traffic, a second interface configured to transmit or receive non-backbone traffic, and a third interface in communication with the first interface and second interface, the third interface configured to multiplex or demultiplex the backbone traffic and the non-backbone traffic is disclosed, wherein the backbone traffic is traffic that will be, is, or has been B-tagged. Also disclosed is a node comprising a processor configured to implement a method comprising receiving a first data stream comprising backbone traffic, receiving a second data stream comprising non-backbone traffic, and multiplexing the first data stream with the second data stream.
摘要:
A network comprising a switch configured to switch traffic between a plurality of external interfaces via a plurality of virtual interfaces associated with the external interfaces, and wherein the traffic comprises a plurality of external virtual local area network (VLAN) identifiers (VIDs) associated with the external interfaces to select the virtual interfaces. Also disclosed is a network component comprising at least one processor configured to implement a method comprising receiving a frame from a physical port, obtaining an external VID from a VLAN tag in the frame, removing the VLAN tag from the frame, selecting a virtual interface based on the external VID, and delivering the frame to the selected virtual interface.
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 common management identifier. Also disclosed is a communications network component comprising logic that supports connection-oriented traffic and Virtual Local Area Network (VLAN)-based connectionless traffic, wherein the logic propagates management messages as VLAN-based connectionless traffic having a unique VLAN identifier (VID). Included is a communications network component comprising at least one processor configured to implement a method comprising provisioning a unique VID for management messages, and selectively propagating management messages with the unique VID.
摘要:
A packet communications network that transports a plurality of traffic over a plurality of server transport paths from a source to a destination, the network comprising: using a load distribution method to distribute each instance of traffic to an individual transport path, thereby avoiding reordering at the destination; enabling all the transport paths to carry the traffic; allowing the network to provision a preferred traffic distribution through a policy setting; and redistributing the traffic when a condition on one of the transport paths changes. Also disclosed is a composite transport group component comprising: a processor configured to implement a method comprising: receiving a server trail failure notification message; and performing a dynamic redistribution of traffic over a plurality of server trails, thereby transporting substantially all of the traffic associated with a class of traffic transported over the server trail associated with the server trail failure notification message.
