A method for packet-oriented transmission of speech, audio, video and/or useful data between an internal and a public data network by means of a pre-reservation of NAT addresses. A pre-NAT address is allocated to the IP address of an internal computer by an NAT address server. The relevant allocation data set is available in a NAT host 200 which acts as a gateway between the internal and the public data network; whereby single addresses (pre-NAT addresses) are provided for transparent use of the...

Methods and apparatus for using a novel Care of Address option in a packet header which allows a mobile node to includes its HoA as the source address and its CoA in a new header field referred to herein as a CAO field are described. When the CAO is present, ingress filtering is performed by an access node on the address included in the CAO instead of the address in the source address, e.g., the HoA, or, is performed on the address in the CAO option field in cases where the source address does n...

A base station for use in a wireless network capable of communicating with mobile stations located in a coverage area of the wireless network. The base station comprises a first base station controller (BSC) that receives data packets from a content server via a packet data network coupled to the first BSC and transmits the received data packets to a first one of the mobile stations via a first base transceiver subsystem (BTS) associated with the first BSC. The first BSC, in response to a first ...

A method and apparatus for configuring a network interface to support a virtual private network includes storing configuration data at a server on a host computer on the provider network. It is determined without human intervention whether conditions are satisfied for sending the configuration data to a particular node at an edge of the provider network without receiving a request message from the particular node. If it is determined that conditions are satisfied, then the configuration data is ...

A source node of a network transmits a path setup message for requesting a traffic path to a destination node. First and second nodes, located between the source and destination nodes, establishes first and second parallel transport paths on a first fault recovery layer between them. The first node further includes a database for storing identities of the first and second paths as a single virtual link as viewed from the source node. The first node responds to the path setup message for accommod...

The invention relates to a method for operating an isochronous, cyclic communication system, wherein one communication cycle can be subdivided into a first part for real-time communication and a second part for non-real-time communication. The communication system comprises subscribers and a memory is provided to store configuration data in each subscriber. The inventive method comprises the following steps: the communication system is operated with first configuration data for real-time communi...

An apparatus and method for weighted non-binary RA coding and space-time coding are disclosed. Transmission data is divided in the units of frames each having mN bits, and each frame is further segmented into N blocks, each block containing m bits. The N blocks are converted to N non-binary GF(2.sup.m) elements. These N non-binary symbols are repeated by a repetition factor r. The rN symbols are multiplied by weighting factors being GF(2.sup.m) elements other than zero. The rN weighted symbols a...

Techniques are provided for the configuration of a home-networking system. Home-networking configuration information may be stored on a host system in a manner accessible to the home-networking system and migrated to a home-networking gateway or router that has not yet been configured. Wireless configuration information may be stored on a home-networking gateway or router and used to configure one or more wireless access points through the use of a physical connection, such as a wired communicat...

A network router integrates routing functionality with accounting functionality for generation of flow statistics, and provides packet intercept functionality to provide a comprehensive traffic analysis environment. The router includes a set of interface cards to receive packets from a network, and a control unit to generate a first and second duplicate stream of the packets. The control unit provides the packets of the first stream to accounting modules for calculation of flow statistics, and a...

A method and apparatus for providing IP-VPN services for customers and service providers utilizing layer-2 point-to-point connectivity. The method and apparatus include exchanging unique loop-back addresses of customer edges (CE) between the CEs via a respective data virtual circuit therebetween, and sending IP addresses of customer networks associated with each CE to an associated IP service controller (IPSC). The associated IPSC broadcasts the IP addresses of the associated customer networks t...
