Abstract: A packet header processing engine includes a level 2 (L2) header generation unit and a level 3 (L3) header generation unit. The L2 and L3 header generation units are implemented in parallel with one another. The L2 generation unit writes L2 header information to a first buffer and the L3 generation unit writes L3 header information to a second buffer. When the L2 and L3 header generation units finish processing a packet, the packet may be unloaded from the first and second buffer while a new packet is simultaneously loaded to the packet header processing engine.

Abstract: Several systems for supporting packet processing are described. A first system supports virtual routing of a packet. A second system supports de-multiplexing of a packet. A third system supports advanced MPLS label processing of a packet.

Abstract: Methods and Systems are provided for a distributed Provider Edge (PE). A single Virtual Routing and Forwarding device (VRF) is associated with a single customer site. The VRF includes a single routing table (RIB) and a single forwarding table (FIB). The VRF also includes a plurality of Virtual Private Network (VPN) Protocol Instance Modules (VRP), where each VRP is associated with a different VPN from the customer site. Each VRP accesses the RIB directly and the FIB indirectly to acquiring addressing/routing information for a received data packet. Moreover, each VRP uses a data plane of the VRP to communicate the data packets to a PE backbone device. In turn, the PE backbone device uses the data plane to communicate with each of the VRPs, and the PE backbone device communicates with one or more tunnels.

The method includes starting a supervision timer at the beginning of a packet access procedure, the packet access procedure initiated by scheduling the sending of a packet channel request message and performing cell re-selection when the supervision timer expires, wherein the supervision timer is stopped when any message is received from a network in response to the packet channel request message or after M+1 (M?0) attempts to send the packet channel request message.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method includes retrieving a profile and a routing table from an access server by a first endpoint during an authentication process. The profile identifies at least a second endpoint as an endpoint with which the first endpoint has permission to communicate. The routing table contains address information needed for the first endpoint to communicate directly with the second endpoint. The first endpoint sends a notification message directly to the second endpoint using the address information to inform the second endpoint that the first endpoint is online.

Abstract: A method of configuring values of cell re-selection parameters for cell re-selection from a serving cell to a neighboring cell in a wireless communication system is disclosed. The method includes receiving from a network a first message via a first control channel, wherein the first message includes values of a first group of cell selection parameters, assigning pre-stored values of the cell selection parameters for the serving cell to values of a second group of the cell selection parameters, if the first message does not include the values of the second group of the cell selection parameters, and calculating the values of the cell re-selection parameters using the values of the first and the second groups of the cell selection parameters.

Abstract: Techniques are provided for operating a network where router devices forward received data packets towards a destination node. Each router maintains a routing table, indicating the next hop to choose in respect of different ultimate destinations m accordance with a routing protocol. Periodic communications between neighboring routers are used as confirmation that they are still able to communicate with one another. Each router compares the time since it last communicated in this way with each of its neighbors with a router dead interval and determines that the respective neighboring router, or the currently designated route thereto, has gone down if the comparison indicates that the router dead interval has elapsed without such a communication having been received. Each router performs an adaptive algorithm to modify the or each corresponding router dead interval dynamically in accordance with one or more properties of the network as measured by the router.

Abstract: In order that media access slots MAS are allocated based on minimum latency requirements of, for example, not less than 4 ms, or on a medium utilization efficiency or power consumption requirement for a minimum reservation block length, both high-efficiency and low-latency schemes (or category) need to coexist within a superframe with fair support given to both. The maximization of contiguous available MAS between low-latency and high-efficiency schemes ensures that power saving and overhead risk are minimized without compromising the support for low-latency applications.

Abstract: The method according to the present invention provides synchronization in a heterogeneous mobile network, for the purpose of interoperability, of a wireless local area network, in which a medium is reserved for a certain service or user in radio channel reservation periods (702) of variable duration, to a radio access network, transmitting data in transmission time intervals of pre-defined duration (603). The variable duration of a radio channel reservation period (702) is defined such that it ends by a pre-defined time period (609) before the end of a transmission time interval (603). The method may be implemented in an access point (1400) of a heterogeneous network as well as in a mobile station (1500).

Abstract: The present invention relates to a marking determining method and a related device for determining a packet marking of packets of an incoming packet-flow, in order to keep the packets in conformance with a traffic policy. The determining is based on an actual value of a traffic reservation parameter, while the traffic reservation parameter is a measure of available network resources dedicated to packets of said incoming packet-flow having a pre-assigned priority. The determining further is based on the pre-assigned priority of the packets of the incoming packet flow. The marking method a first steps of holding a threshold value for the traffic reservation parameter, while the threshold value is lying between a minimum and a maximum value of the traffic reservation parameter.

Abstract: A decentralized data network contains a plurality of network nodes. The network nodes are able to direct requests into the data network with the aid of checking values. The network nodes are each assigned one or more table entries in a value table distributed between the network nodes, with each table entry containing a checking value and the data associated with the checking value. Each of the plurality of network nodes are monitored to determine the frequency with which requests for the checking values assigned to a respective network node are directed to the respective network nodes. If it is found that the frequency of the requests for one or more checking values to a respective network node exceeds a predetermined threshold value, at least the table entry or entries for this or these checking values is or are assigned to at least one other network node.

Abstract: According to the present invention, simultaneous call-handling and data transfer is achieved between a terminal and a multi-line gateway in a cordless telephony environment. Multiple logical channels are established and used as signaling resources for calls on the multiple lines, and also for data transfers between the gateway and terminal. As a result, terminals can handle multiple calls on different lines and at the same time access data stored at the gateway. According to a first aspect of the present invention, two or more logical channels are established over an asynchronous channel between a terminal and a gateway. These logical channels are assigned to calls that are set-up between the terminal and gateway. When used as a signaling resource, the logical channels allow the terminal to distinguish between signaling information for multiple simultaneous calls. The calls are associated with another speech or data channel that will bear the voice signal, referred to herein as a bearer channel.
