    Abstract: A Session Admission Control (SAC) for negotiating admission control in a multi-services communications network including multicast services is described. The module distributes the admission process between a centralized decision function (SAC-PDP) and a distributed decision function (SAC-M) in a fashion that solves admission control scaling problems. The mechanism for interaction between the SAC-PDP and SAC-M is defined. Mechanisms are defined for the SAC-PDP to discover or learn the network capacity against which the admission control decisions will be made. Systems are also described for incorporating SAC-M in multicast replication points in the network, allowing multicast replication points to participate in the admission control process.

    Abstract: Public and private network service management systems and methods are disclosed. Rules for accessing a private services network in which network services are available are enforced so as to restrict access to the services network through a public network in accordance with policies of the services network. Use of network services by a client of the private services network through the public network is controlled according to network service access policies associated with the network services. Network services provided by clients of the services network which access the services network through a public network may also be offered to other clients of the services network through the services network and the public network.

    Abstract: A system and method are provided for creating an XML network. As each XML router is added to the XML network, the new XML router registers with a group of existing XML routers in the network, and thereafter regularly exchanges hello messages with other XML routers in order to announce its initial and continued presence. Once an XML router is added to the group of routers forming the network, the adjacency of the new XML router is determined. The new XML router selects its adjacency based on a prioritized set of metrics, including TCP hops, IP cost, and fanout, along with specific parameters relating to fanout and IP cost. The order of priority of the metrics and the specific parameters can be set by an operator, allowing flexibility in creating an optimum XML network topology.

    Abstract: Publish-subscribe XML multicast service within a VPN service is described. A backbone such as an IP/MPLS backbone connects multiple subscriber sites using VPN technology and VPN edge routers. XML publish-subscribe modules are addressable within the VPN and form an overlay network between the edge routers participating in the VPN. The XML publish-subscribe modules may perform either topic-based multicast or content-based multicast services. The multicast service is self-managed.

    Abstract: A system for providing resilient multimedia broadcasting services over a VPLS network is described. A network Management System (NMS) calculates disjoint minimum cost trees using the Steiner algorithm executed with extra steps to result in the disjoint trees. Destination PE routers in the VPLS network are connected to the disjoint trees so that they can be serviced by either tree in the case of a fault. Each of the disjoint trees is provisioned with enough bandwidth to carry all of the services provided by the VPLS network. Under normal operation, however, the services are distributed evenly over the trees. In the event of a fault, the services on the faulty tree are switched to the other tree using split horizon bridging. Each Steiner tree can also be realized using poin-to-multipoint LSPs which is fully protected by a precomputed point-to-mulltipoint LSP.

    Abstract translation: 描述了一种通过VPLS网络提供弹性多媒体广播业务的系统。 网络管理系统(NMS)使用执行了额外步骤的Steiner算法来计算不相交的最小成本树,从而导致不相交的树。 VPLS网络中的目的PE路由器连接到不相交的树,以便在故障的情况下可以由任何一个树进行服务。 每个不相交的树被提供足够的带宽以承载由VPLS网络提供的所有服务。 然而,在正常运行中,服务均匀分布在树上。 在发生故障的情况下,故障树上的服务使用水平分割桥接切换到另一棵树。 每个Steiner树也可以使用由预先计算的点对多点LSP完全保护的poin-to-multipoint LSP来实现。

    Abstract: A method and apparatus for monitoring data traffic in a communication network are provided. A router connected to the communication network monitors information contained in the data traffic, and based on the information determines whether data in the traffic is indicative of a malicious threat to one or more resources connected to the network. Parameters which control monitoring of traffic at the router, such as the sampling rate and what information is to be extracted from the data is varied according to the condition of the network so that the monitoring can be adapted to focus on traffic which relates to a particular suspected or detected threat.

    Abstract: Network services infrastructure systems and methods are disclosed. Policies for client access to a services network and network services available in the services network are enforced at client gateways. Once authenticated and authorized at a client gateway, a client of the services network may make its own network service(s) available in the services network, use network services provided by other clients of the services network, or both. The policies are centrally managed within a services network and distributed to the client gateways. Various registries which store policies, information associated with network services, and possibly other information may also be provided.

    Abstract: Methods, tools, and a multicast connectivity architecture are provided for provisioning bundled high bandwidth multi-channel multimedia broadcast services over a packet switched communications network. Multicast group membership join/prune requests generated by the destination network nodes are processed on edge. Multicast tree connectivity in the core of the communications network is static and centrally provisioned based on multicast group member edge network nodes associated with subscribers, while dynamic multicasting techniques are employed over the distribution portion of the service provider's communications network to deliver requested content to each destination network node. The methods and tools compute multicast trees, configure on-tree branching network nodes, and establish Virtual Private LAN network overlays for channel bundles to convey multi-channel content in the core of the managed communications network between edge network nodes. Centralized multicast tree provisioning enables the use of efficient multicast tree topologies, while VPLS packet transport provides interoperability between disparate Layer-2 packet transport technologies employed in different portions of the communications network.

    Abstract: Methods directed to longest prefix matching and systems directed to IP address lookups are presented. The methods and systems relate in particular to IPv6 and comprise finding the longest prefix match (LPM) for an IP address. The method of the invention results in the use of filters to perform LPM. In embodiments of the invention, partial address filtering is used to further reduce filtering requirements. Reducing the number of filtering operations has the advantage of making the LPM algorithm faster and less costly to implement than prior art approaches. Also described is an “ideal offset filter” that extracts a fixed sized sliding window of bits from the IP address being processed.
