The present invention provides a system for operating a power line communications system that employs surface wave communications and conducted communications. The system is comprised of a plurality of network elements, which may take the form of repeaters, communication interface devices, backhaul devices, medium voltage transducers, distribution points, aggregation points, and others. In one embodiment, surface waves are communicated over the medium voltage power lines and the conducted communications are communicated via the low voltage power lines to and from customer premises.

A policy-based network security management system is disclosed. In one embodiment, the system comprises a security management controller comprising one or more processors; a computer-readable medium carrying one or more sequences of instructions for policy-based network security management, wherein execution of the one or more sequences of instructions by the one or more processors causes the one or more processors to perform the steps of receiving a set of data regarding a user of a computer network; automatically deciding on a course of action based on the set of data, wherein the course of action may be adverse to the user although the set of data is insufficient to establish whether the user is performing a malicious action; and sending signals to one or more network elements in the computer network to implement the decision.

Routes may be installed across multiple link state protocol controlled Ethernet network areas by causing ABBs to leak I-SID information advertised by BEBs a L1 network area into an L2 network area. ABBs will only leak I-SIDs for BEBs where it is the closest ABB for that BEB. Where another ABB on the L2 network also leaks the same I-SID into the L2 network area from another L1 network area, the I-SID is of multi-area interest. ABBs will advertise I-SIDs that are common to the L1 and L2 networks back into their respective L1 network. Within each L1 and L2 network area, forwarding state will be installed between network elements advertising common interest in an ISID, so that multi-area paths may be created to span the L1 / L2 / L1 network areas. ABBs may summarize BEB multicast trees such that the set of trees for a given I-SID transiting the ABB is condensed into a common tree. The L2 network may further be implemented as a second layer implemented using a L1 / L2 / L1 network structure, so that the L1 / L2 / L1 network structure may recurse an arbitrary number of times.

The present disclosure relates a network, a network element, a system, and a method providing an efficient allocation of protection capacity for network connections and / or services. These may be for services within a given Virtual Private Network (VPN) or Virtual Machine (VM) instance flow. Network ingress / egress ports are designed to be VM instance aware while transit ports may or may not be depending on network element capability or configuration. A centralized policy management and a distributed control plane are used to discover and allocate resources to and among the VPNs or VM instances. Algorithms for efficient allocation and release of protection capacity may be coordinated between the centralized policy management and the distributed control plane. Additional coupling of attributes such as latency may provide more sophisticated path selection algorithms including efficient sharing of protection capacity.

A PLCS network element that provides communications to one or more user devices and may also repeat data for other network elements is provided. In one embodiment, the device includes software for discovering its upstream gateway, for acting as a gateway for other devices, and for relaying DHCP transmissions. In addition, the device includes software for receiving and processing commands from a remote computer system that may include commands enabling and disabling the repeater functionality. Finally, the device may also include software for receiving and processing configuration information that may include, for example, information of the other network devices for which it will repeat.

This invention relates to apparatus and a method for assembling and coordinating call data records from a plurality of network elements of an Internet Protocol Multimedia System call to generate charging information. A pre-biller stores an integrated charging record and accesses a rating engine to obtain the charging information to complete a charging data record. Advantageously, the information from a plurality of network elements is integrated into a combined charging data record.

A network-based system and method for providing anonymous voice communications using the telephone network and data communications links under the direction of a Call Broker and associated network elements. A user (the call initiator) present in a text chat room session establishes a data connection to Call Broker and, after qualifying for access (e.g., using credit card information) and providing a callback number, receives voice session information and participant access codes for each desired participant in a voice call. The initiator causes session information and participant codes to be passed to one or more selected chat participants in the current text chat room. When a selected participant uses the received session information, and enters the received participant code and a callback number, the Call Broker in cooperation with a Network Adjunct Processor (NAP) completes voice links to the initiator and the selected participant(s). The need for each party to have a second subscriber line is advantageously avoided by having the Call Broker arrange to have one or more voice links completed through a VoIP link, and further reduces the need for second lines for participants by forwarding a Call Broker—placed call to a busy participant line to the participant's Internet Service Provider (ISP), which then sends a message to the participant announcing one or more options for receiving the incoming call, including receiving the incoming call through a VoIP link.
