Abstract: A method of assigning a predetermined IP address to a device for installation on a private network. This IP address can be assigned before installation into any private network without having to be reassigned and without creating addressing conflicts, thereby simplifying the installation process. A registered global IP address is obtained from an Internet Registry and assigned to a multiplicity of devices. Exactly one such device is installed on the private network. The device has an internal router that captures data packets associated with the global IP address, so that this traffic is not put onto a public network connected to the private network. Because the registered global IP address is unique and intended for public networks, no other device on the private network has this address. Thus, the device's assigned IP address is guaranteed not to conflict with existing IP address assignments on the private network.

The edge node can also include a virtual interface creation configured to create a virtual interface that is enabled for multicast. The packet rewrite module can encapsulate the multicast packet in response to detecting that the multicast packet is being sent via the virtual interface.

A C control-message generating unit generates a C control message to request connection establishment or connection removal. A C control-message transmitting unit sends the C control message to an OLT.

Abstract: A method is disclosed that provides a way to manage the registrations of telecommunications endpoints, and to prioritize those registered endpoints, or “contacts,” that belong to a user, without some of the disadvantages in the prior art. The technique of the illustrative embodiment, which is referred to as “contact priority reordering,” prioritizes the contacts that are associated with a Session Initiation Protocol (SIP) public address of a user, without having to modify any endpoints. Moreover, the technique is interoperable with any SIP endpoint. The technique can be regarded as a reordering process because it overrides any endpoint ordering that occurs at a registrar server as a consequence of the registrations and re-registrations of the individual endpoints. Advantageously, the technique prioritizes the contacts that are associated with a particular public address without requiring that any changes be made to the registrar server—or to any other SIP servers.

Abstract: A technique efficiently routes Internet Protocol (IP) traffic on paths between customer edge devices (CEs) across a provider network (“CE-CE paths”) in a computer network. According to the novel technique, a path computation element (PCE), e.g., a provider edge device (PE), may learn dynamic link attribute information of remote links from the provider network to one or more remote CEs (e.g., “PE-CE links” or “CE-PE links”). A multi-homed requesting CE requests from the PCE a set of CE-CE path metrics (e.g., costs) to one or more remote destination address prefixes, e.g., via each multihomed CE-PE link from the requesting CE. In response to the request, the PCE computes the set of available CE-CE paths and current metrics to the remote destination address prefixes and returns the corresponding CE-CE path metrics to the requesting CE. The requesting CE modifies its IP forwarding entries accordingly in order to perform IP traffic routing corresponding to the CE-CE path metrics (e.g.

Abstract: Systems and methods that facilitate the selection and connection of sub-devices managed by virtual device or logical units (LUs) within a network. In one exemplary embodiment, LU connections are preferably brought to the IP layer using HTTP commands and responses. These IP layer commands are used to communicate connection information among the LUs involved in the connection and to allow for LUs to determine which sub-devices within the LU will be used in a connection. When the specific details have been determined, the sink device will work at the network specific level to make the actual connection. This allows for the connections between LUs to be network independent until all of the specific details of the connection have been determined. After that, a connection is established using network specific commands and protocols.

Abstract: A method of using a point-to-point (P2P) label switched path (LSP) to transmit multicast data packets partially through a multiprotocol label switched (MPLS) network when one or more label switched routers (LSRs) of the MPLS are not multicast label distribution protocol (mLDP) enabled. The P2P LSP can be used to transmit multicast data packets to the head end of a point-to-multipoint (P2MP) LSP created with mLDP enabled LSRs. The P2MP LSP can be used to transmit the multicast data packets through the MPLS network to intended receivers that are external to the MPLS network. When configuring the P2MP LSP, an mLDP enabled LSR receives a first message from a non-mLDP enabled MPLS core router in response to sending a label mapping message to the non-mLDP enabled MPLS core router. In response, a directed LDP session is created between the mLDP enabled LSR and an edge LSR in one embodiment in response to receiving the first message from an MPLS enabled core router.
