International Classification:

H04L 12/28

US Classification:

370230, 370254

Abstract:

A system for providing aggregate-rate communication services is provided. The system comprises a provider network, having an arbitrary topology; a plurality of customers; and a plurality of port nodes, comprising at least one aggregation-group. Port nodes in the at least one aggregation-group share capacity of the at least one aggregation-group fairly. Each of the plurality of customers is associated with at least one of the plurality of port nodes to access the provider network.

Inventors:

Linda Dunbar - Plano TX, US

Assignee:

Futurewei Technologies, Inc. - Plano TX

International Classification:

H04J 1/16

US Classification:

370241

Abstract:

According to an embodiment, the present invention provides a method for transferring data in a packet-based network. The method includes a step for receiving at least a first data frame. The first data frame is associated with a first origination node and a first destination node. The method includes a step for processing information associated with the first data frame. The method includes a step for determining whether the first data frame satisfies at least one predetermined condition based on at least information associated with the first data frame. If the first data frame is determined to satisfy the at least one predetermined condition, the method includes a step for providing a second data frame based on at least information associated with the first data frame, where the second data frame is associated with a second origination node and a second destination node.

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.

International Classification:

H04J 3/16
G06F 15/173

US Classification:

370468, 709225

Abstract:

A telecommunications network comprising components configured to implement a method comprising: receiving a reservation from a customer, reserving a network resource specified in the reservation, initiating the establishment of a reserved connection through a network, the reserved connection parameters based on the reservation, subsequent to the establishment of the reserved connection, detecting a data stream transmitted from the customer, and allowing the data stream to be transported over the network using the reserved connection. Also disclosed is a method for reserving bandwidth on a network, the method comprising: submitting a reservation request specifying a bandwidth requirement and a start time, receiving a confirmation that the reservation has been accepted, and transmitting a data stream to a network at the start time, wherein the data stream is transported over the network using no more than the bandwidth specified in the reservation request.

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.
