Assignee:

AT&T BLS Intellectual Property, Inc. - Wilmington DE

International Classification:

H04L 12/28

US Classification:

370256, 37039521, 370408, 370477

Abstract:

A method for traffic engineering of connectionless virtual private network (VPN) services. The method comprises receiving physical connectivity data for a connectionless VPN including service nodes and links between the service nodes. One or more of the service nodes are also edge nodes. Logical connectivity data for the edge nodes is received. A restricted topology is created in response to the physical connectivity data and to the logical connectivity data. The restricted topology includes a single path between each pair of the edge nodes and each path includes a plurality of the service nodes and one or more of the links. A bandwidth requirement for each link in the restricted topology is calculated. The bandwidth requirement is reserved on each link in the restricted topology. The method further comprises directing routing software to force a packet received from an edge node through one of the paths in the restricted topology.

International Classification:

H04L 12/66

US Classification:

370352, 370484, 370485, 375222

Abstract:

Methods and systems provide network access service for a subscriber by utilizing multiple asymmetric DSL modems per service point such that the available bandwidth is the aggregation of the multiple asymmetric DSL modems. One asymmetric DSL modem of a service point has a faster upload speed than download speed while another asymmetric DSL modem of the service point has a faster download speed than upload speed. The two asymmetric DSL modems are aggregated together at the service endpoint so that the service endpoint benefits from the upload and download bandwidth available from both asymmetric DSL modems. The two asymmetric DSL modems at one service point communicate with two asymmetric DSL modems aggregated at another service point to complete the exchange of data. The network access service using DSL connectivity may be made symmetric by providing one of the asymmetric DSL modems with an upload speed that is substantially the same as the download speed of the other asymmetric DSL modem, while the download speed of the one is substantially the same as the upload of the other.

Assignee:

AT&T Deleware Intellectual Property, Inc. - Wilmington DE

International Classification:

H04J 3/16

US Classification:

370468

Abstract:

A packet switched communications network that includes nodes that are interconnected by links, is dimensioned to accommodate committed bandwidths for ports that are connected to packet switched communications network. Bandwidth of a given link that includes first and second ends is provided, based on a link dimensioning rule that is a function of committed bandwidths from ports that are connected to the first end of the given link and ports that are connected to the second end of the given link. The packet switched communications network provider agrees to provide communications service for a customer through the packet switched communications network at a first committed bandwidth. At least some of the links are dimensioned to accommodate the first committed bandwidth. Upon occurrence of degraded performance for the customer over the packet switched communications network, the packet switched communications network provider agrees to provide communications service for the customer at a second committed bandwidth that is greater than the first committed bandwidth. The packet switched communications network provider then dimensions at least some of the links to accommodate the second committed bandwidth.

International Classification:

H04Q 7/14

US Classification:

Abstract:

Quality of Service (QoS) and/or bandwidth allocation can be provided for interactive gaming via a Regional/Access Network (RAN). The RAN can provide end-to-end transport between a Gaming Application Service Provider (GASP) and a Customer Premises Network (CPN) that includes a Routing Gateway (RG). Quality of Service (QoS) and/or bandwidth allocation can be provided by determining different levels of subscription service for different subscribers to an interactive game between a plurality of participants. Different QoS and/or bandwidth allocations can be provided to different gaming traffic flows associated with the different subscribers to the interactive game based on the different levels of subscription service of the different subscribers.

International Classification:

H04J 3/22

US Classification:

370468, 370252, 709223

Abstract:

Quality of Service (QoS) in a communication network is managed. A service provider requests a level of QoS for communication in the communication network using a QoS request. The requested level of QoS may be allocated to the service provider based on the QoS request. The service provider may make the QoS request on its own initiative and/or in response to a request from an application that is hosted by the service provider. A QoS level may then be allocated to the service provider and/or to particular applications that are hosted by the service provider.

US Classification:

709229, 709201, 709202, 709203

Abstract:

A method for providing Ethernet VLAN capacity requirement estimation. The method includes receiving a VLAN that contains VLAN access ports, VLAN switches and VLAN trunks. The VLAN access ports include VLAN bandwidth requirements and VLAN class of service. The VLAN trunks include VLAN capacity counters and VLAN threshold parameters. A target access port is received from a requestor, the target access port includes a target class of service and a target bandwidth requirement. A target trunk and target switch corresponding to the target access port are determined. The target trunk corresponds to one of the VLAN trunks and the target switch corresponds to one of the VLAN switches. A bandwidth contribution of the target access port to the VLAN is calculated. The calculating is responsive to the VLAN trunks, the VLAN switches, the VLAN access ports and the target access port. The bandwidth contribution is then transmitted to the requester.

US Classification:

370260, 3703952, 370467

Abstract:

These exemplary embodiments utilize Sessions Initiation Protocol (SIP) for admission control among a plurality of multimedia devices. The use of the SIP allows a SIP server to perform admission control functions. The use of RSVP linkages is reduced. The use of SIP for admission control allows an application to communicate, or “talk,” to a network and other multimedia devices and to request that resources within the network be reserved. Any communications device that uses sessions may utilize the SIP protocol for admission control. The SIP protocol may be used for unicast and multicast media sessions including video-on-demand and/or multicast video access control.
