Appl. No.:

12/714928

Inventors:

T. Benjamin Mack-Crane - Downers Grove IL, US
Linda Dunbar - Plano TX, US
Robert Sultan - Somers NY, US
Lucy Yong - McKinney TX, US

Assignee:

Futurewei Technologies, Inc. - Plano TX

International Classification:

H04L 12/28

US Classification:

370392, 37039553, 370401

Abstract:

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, 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, and wherein the virtual interfaces are configured to forward traffic based on an internal VID that is assigned to the traffic independent of the external VID. 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.

International Classification:

H04L 12/28
G06F 15/177

US Classification:

370254, 37039553, 709220

Abstract:

A network component comprising at least one processor configured to implement a method comprising receiving a message comprising a node's data value from the node, determining whether a local data value has been assigned, and adopting the node's data value as the local data value when the local data value has not been assigned. Also disclosed is a network component comprising a plurality of ports each configured to couple to a node via a link, a memory configured to store a port data value associated with at least some of the ports, and a processor coupled to the memory and the ports, wherein the processor is configured to access a node's data value in a message and adopt the node's data value as the port data value.

H04L 12/56

US Classification:

370392, 370389, 37039531, 37039532

Abstract:

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.

International Classification:

H04J 3/16

US Classification:

370466, 370465

Abstract:

A network comprising an ingress layer processor (LP) coupled to a connection carrying a composite communication comprising a plurality of component communications, a composite connection coupled to the ingress LP and comprising a plurality of parallel component connections, wherein the composite connection is configured to transport the component communications using the component connections, and an egress LP coupled to the composite connection and configured to transmit the composite communication at a connection point. Also disclosed is a network component comprising at least one processor configured to implement a method comprising receiving a connection carrying a plurality of component communications, reading a communication distinguishing fixed point (CDFP) from at least some of the component communications, and accessing a table associating at least some of the CDFPs with at least one component connection.

Assignee:

FUTUREWEI TECHNOLOGIES, INC. - Plano TX

International Classification:

H04L 12/26

US Classification:

370253

Abstract:

An apparatus comprising a first node configured to couple to a second node, wherein the first node is further configured to exchange a plurality of timestamps recording transmission times and at least one of a plurality of octet counts and a plurality of frame counts with the second node to perform throughput measurements, and wherein the at least one of the plurality of octet counts and the plurality of frame counts correspond to a packet flow between the first node and the second node and are used to calculate throughput for the packet flow based on a time interval of the exchanged at least one of the plurality of octet counts and the plurality of frame counts that is determined using the timestamps.
