H04L 12/56

US Classification:

3702362, 3702411, 3703953

Abstract:

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.

Robert Sultan - Somers NY, US
Linda Dunbar - Plano TX, US

Assignee:

Futurewei Technologies, Inc. - Plano TX

International Classification:

H04L 29/04

US Classification:

370470

Abstract:

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.

International Classification:

G06F 15/16

US Classification:

709252

Abstract:

A network comprising a plurality of trees each comprising at least one ingress leaf node, at least one interior node, and at least one egress leaf node, wherein at least some of the ingress leaf nodes and the egress leaf nodes are common to the trees, and wherein the ingress leaf node is configured to transport data to the egress leaf node using any of the trees is disclosed. Also disclosed is a network component comprising a processor configured to implement a method comprising selecting one of a plurality of trees associated with information contained within a frame, directing the frame to the selected tree, and maintaining a filtering database (FDB) entry in an interior node in the unselected tree or trees.

US Classification:

709223, 709201, 709208

Abstract:

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.

International Classification:

H04J 3/24

US Classification:

370474

Abstract:

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.
