Filed:

Feb 9, 2006

Appl. No.:

11/350029

Inventors:

Roman Maria Krzanowski - White Plains NY, US
William Arthur Bjorkman - Danbury CT, US
Haidar Ahmed Chamas - White Plains NY, US
Vincent Anthony Alesi - Yorktown Heights NY, US

Assignee:

Verizon Services Corp. - Ashburn VA

International Classification:

H04L 12/56

US Classification:

370235, 370229, 370236, 709230, 709232

Abstract:

The present invention, including system methods and computer program product, provides the ability to control the flow of traffic into an aggregated trunk port in a network. This is performed by monitoring the trunk port of an aggregation packet switch for congestion and limiting the traffic flowing into the aggregation packet switch through virtual connections with one or more user network interfaces. An access control system executing an access control algorithm monitors the trunk port and controls the user network interfaces to limit the traffic the passes through the trunk port in the event of traffic congestion. Traffic may be limited on the basis of the class of service, the virtual connection, or other parameters.

International Classification:

H04L 12/26

US Classification:

370235, 370229, 709223, 709226

Abstract:

Traffic flow is monitored in a plurality of links. Based on the monitoring, a manner in which traffic is allocated to the links is determined, and at least one policer is assigned according to the manner in which traffic is allocated to the links.

US Classification:

37039521, 37039541, 37039543, 370468

Abstract:

In one of many possible embodiments, a system includes a plurality of queues configured to share an amount of bandwidth, the amount of bandwidth being allocated between the queues in accordance with a plurality of queue weighting factors associated with the queues. The system further includes an admission control subsystem configured to dynamically adjust the queue weighting factors when a predefined condition has been satisfied. In certain embodiments, the admission control subsystem is configured to adjust the queue weighting factors based on a ratio of bandwidth provisioned on the plurality of queues. In certain embodiments, each of the queues is associated with a different class of service.

US Classification:

370256, 37039221, 370238, 370232, 370351, 709241

Abstract:

An admission control system is disclosed in combination with a network and a computing system in communication with the network. The computing system is configured to determine a class of service requirement from a service request. The computing system is furnished with topology information about the network, a portion of the topology being based on a protocol (e. g. , Multiple Spanning Tree protocol) whereby multiple paths are created for provisioning a connection for the service request. A mechanism is configured to determine if at least one path is available that satisfies the class of service requirement and to admit the service request into the network when the path is available for provisioning the connection. Bandwidth usage may be tracked and used in provisioning decisions. Requests may be made to the network to add bandwidth (e. g.

US Classification:

370241, 37039553

Abstract:

A method includes monitoring, by a first network device, traffic from a customer device, wherein the traffic is to be forwarded via a provider's network. The method also includes identifying a traffic pattern associated with the traffic, identifying a link on which the identified traffic pattern was transmitted and generating performance monitoring traffic. The method further includes forwarding, by the first network device, the performance monitoring traffic to the provider's network via the link on which the identified traffic pattern was transmitted.
