20080225857 | Low-impact call connection request denial - A policy enforcement point (PEP) attaches to the edge of a packet-switched network to manage loading when the network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. Autonomous PEP's at the network's edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. Changes become necessary when a network event results in a loss of resilient bandwidth that effects the traffic class under admission control. Or, when an unexpected surge in traffic exceeds the PEP's reserved resources to a particular destination. The resources available across the network are recalculated for minimizing impact on existing sessions or calls, and it informs the PEP's of the new resources available. If the new maximum exceeds the current utilization to that destination, the PEP invokes a local priority drop mechanism to back off the traffic until it is under the new limit. A media gateway handling voice calls can keep all emergency calls up, and then invoke a local algorithm, such as random drop, for the remaining calls until calls to the constrained destination are under the new limit. In the second case, where there is an unexpected surge in demand, the PEP can request from the bandwidth manager additional resources to a particular destination. | 2008-09-18 |

Each of the first plurality and second plurality of processing nodes includes one or more first tier links among the plurality of first tier links, where the first tier link(s) within each processing node connect a pair of processing units in the same processing node for communication. The data processing system further includes a plurality of point-to-point second tier links. At least a first of the plurality of second tier links connects processing units in different ones of the first plurality of processing nodes, at least a second of the plurality of second tier links connects processing units in different ones of the second plurality of processing nodes, and at least a third of the plurality of second tier links connects a processing unit in the first plane to a processing unit in the second plane. | 2008-09-18 |
20080225864 | COMMUNICATION NETWORK ROUTING APPARATUS AND TECHNIQUES USING LOGICAL COMMUNICATION LINKS - Communication network routing apparatus and techniques using logical communication links are disclosed. A routing apparatus identifies a logical communication link that it is capable of being used to establish a virtual connection with another routing apparatus within a virtual connection operational domain, which includes multiple sub-domains, of an underlying communication system. A destination that is associated with the routing apparatus and is reachable through the virtual connection is also identified. Information that is indicative of the identified logical communication link and of the identified destination is provided for distribution from a sub-domain of the routing apparatus in the virtual connection operational domain to another sub-domain within the virtual connection operational domain. This distribution of information enables a routing apparatus in one sub-domain to dynamically route a virtual connection toward a destination in a different sub-domain. Data structures for distributing the information are also disclosed. | 2008-09-18 |
20080225865 | Cost reduction of NAT connection state keep-alive - Keep-alive processing for NAT devices and reducing power consumption in wireless clients. A server driven keep-alive mechanism facilitates keep-alive messages to a NAT device currently providing a connection to a mobile client to refresh the NAT state, thereby reducing or eliminating power consumption in a wireless device to respond to the connection with keep-alive packets. In one instance, keep-alive packets are sent to the NAT device to reset the NAT timeout timer, and then to the mobile client. The client responds only when expected keep-alive packets are not received at the client. In another instance, keep-alive packets reset the NAT timer to maintain the connection but are dropped or self-destruct before reaching the mobile client thereby providing the optimum power conservation in the mobile device. Thus, the client is not forced into extra client activity to send or receive wireless data, thereby draining the battery. | 2008-09-18 |
