Abstract: A communication device is, in an MPLS network including a first area and a second area, the first area being notified of aggregate route information into which pieces of route information on a plurality of routes are aggregated, and using an LDP for generating an LSP, located in the first area but spans between the first area and the second area and receives a message for generating the LSP using one of the plurality of routes within the second area, wherein the communication device is stored with aggregate route information, pieces of route information and labels, then determines whether the route information in the message is stored or not when receiving the message, and, if not stored, executes a label distribution process if the route specified by the route information is one of the routes aggregated with the stored aggregate route information.

Abstract: A technique for effectively capturing site-to-site traffic statistic without significantly affecting the performance of a router in an MPLS-VPN service network is disclosed. In one example embodiment, this is accomplished by computing source PE IP and source PE interface from each flow record received at a destination PE router to identify an associated source VPN site.

Abstract: Methods and apparatus for a play-out buffer that may adjust offsets between clocks of two ends of a network link with an adaptive play-out buffer and adaptive clock control. The play-out buffer is a circular jitter buffer that permits the absorption of a frequency offset using controlled slips between two nodes of a network. The play-out buffer also accommodates some wander introduced by the time-delay variation across the network. The adaptive clock control reduces the frequency offset between the clocks of the two nodes. In this manner, even though some offsets between two nodes would render communication inefficient, embodiments of the present invention allow the effects of these offsets to be mitigated, thus providing for a better quality coupling.

Abstract: A method and apparatus for segmenting data into TCP data segments using a first network communication component, and transmitting TCP data segments over a second network using a second network communication component. TCP data segments may be created by a first network card that may be in a loopback mode while a second network card may be sending TCP data segments onto a network. Both network communication cards may be operating simultaneously and may improve efficiency.

Abstract: Described herein are a system, method, and computer readable medium for correlating asynchronous communication messages between a mobile communication device and a data source over a network. The mobile communication device executes an application to provide interaction with the data source based on the content of the communication messages. The system includes a message set and a message manager. The message set is configured to correlate an asynchronous request message of the communication messages with a corresponding asynchronous response message of the communication messages. The asynchronous request message has a first correlation identifier when transmitted and the asynchronous response message has a second correlation identifier when received; the first and second correlation identifiers form part of the message set and specify a mapping that correlates a data element of the asynchronous request message and a data element of the asynchronous response message, respectively, with a data instance.

According to the schemes of the embodiments of the present invention, in the NGN, highly effective, secure and reliable network interconnecting is realized through effective control on the border/packet gateway based on the network resources and control policies, and NGN network performance is thus improved.

Abstract: A novel method for coordinating the delivery of frames to and the receipt of frames from a power-saving station in a wireless local-area network (LAN) is disclosed. The illustrative embodiment establishes a wake-up schedule for a power-saving station based on a temporal period and temporal offset that reduces the frequency with which multiple stations in a network wake up simultaneously, thereby reducing traffic delays and power consumption. The illustrative embodiment is particularly well-suited to networks with traffic that has delay/jitter quality-of-service (QoS) requirements (i.e., voice calls, videophone calls, etc.).

Abstract: A network device controls the flow of traffic in a network, such as an Ethernet-based network. The network device detects congestion in the network and identifies at least one upstream device to which to send a flow control message, where the upstream device is a device that is transmitting above a predetermined level. The network device then transmits the flow control message to the identified upstream device. The flow control message instructs the identified upstream device to slow down transmissions to the network device.

Abstract: A media gateway controller (MGC) is described herein that implements a shared risk group package to control and prevent a media gateway (MG) from establishing redundant links like a primary link and a secondary link that use resources that share the same risk of failure. Essentially, the MGC uses the shared risk group package to control which resources like ephemeral terminations are used by the MG to establish the primary link and the secondary link such that if any of the resources associated with the primary link fail then the secondary link remains operational within the MG and if any of the resources associated with the secondary link fail then the primary link remains operational within the MG.

A tiered access protocol enables an Access Point to act as a channel arbitrator and gain control a channel during a contention period. The Access Point waits a specified amount of time before taking control of a channel for either transmitting an outbound frame or initiating Polled-Contention Free Bursts. In addition, a method for increasing the time span between Delivery Traffic Indication Message beacons by tracking when Wireless Stations are able to receive messages and instantly delivering messages to those Wireless Stations.

Abstract: The present invention permits a network operator to maintain a timely view of changes to an operational packet-switched network. In an exemplary embodiment, the method includes subscribing to routing protocol messages received from a plurality of network elements participating in a routing protocol in the packet-switched network. Then, the routing protocol messages from the network elements are received without participating in the routing protocol. Subsequently, the method detects deviations from normal operation of the packet-switched network using the routing protocol messages received from the network elements.

Abstract: The embodiments utilize OFDM symbols to communicate network IDs. The IDs are encoded into symbols utilizing the network IDs as seeds to scramble respective pilots that are then transmitted by utilizing the symbols. The pilots can be structured into a single OFDM symbol and/or multiple OFDM symbols. The single symbol structure for transmitting the network IDs is independent of the number of network ID bits and minimizes frequency offset and Doppler effects. The multiple symbol structure allows a much coarser timing accuracy to be employed at the expense of transmitting additional symbols. Several embodiments employ a search function to find possible network ID candidates from a transmitted symbol and a selection function to find an optimum candidate from a network ID candidate list.

Abstract: According to the inventive method, data from at least one ISDN data link, at least one conventional telephone link and at least one broadband data link, respectively, are transmitted in an SDSL frame of an SDSL data link, with the required control data being transmitted in either the eoc or in one or more Z channels.

Abstract: Time-scattering of data is employed to reduce the interference effects, such as, error rate, between terminals disposed in nearby beams, or cells, of a communication system. A scattering schedule is determined, typically by a gateway, for a terminal. Scattering instructions, based at least in part on that scattering schedule, are provided to the terminal. The scattering instructions provide terminals with information suitable for controlling the temporal scattering of time slot data to be transmitted by the terminals so that interference impact of nearby out-of-beam terminals is reduced. Time-scattered data received by a receiver remote from the terminal is returned to the desired order by sorting the data in accordance with the scattering schedule to achieve a reversing of the scattering. Time-scattering may be applied to data moving in either or both of the forward and reverse directions of a communication system.

Abstract: An integrated egress/replay memory structure is provided with split rate write and read ports and means for managing at least three types of data moving into, through and/or out of the integrated memory structure, namely: (1) currently egressing packet data; (2) replay data; and (3) to-be egressed data. Additionally, a shared free space (4) is managed between the storage areas of the (2) replay data and (3) the to-be egressed data. The to-be egressed data (PdBx) is allowed to enter into (to be written into) a front-end raceway portion of the integrated memory structure at a rate which can be substantially greater than that allowed for corresponding egressing packet data (PdUx). Thus, even when egressing packet data that is ahead in line is shifting out toward a slow rate egress port; this slowing factor does not slow the speed at which the to-be egressed data (PdBx) can be shifted into the front-end raceway portion.

Abstract: Provided is a method for sharing contents between devices using an IEEE 1394 interface in a DLNA system. The method includes transporting a SetAVTransportURI from a DMP to a DMS, and informing the DMS of a URI of a content; upon receipt of the SetAVTransportURI, performing the steps of transporting a “CONNECT” command to the DMP using a protocol, and preparing contents transport between the DMP and the DMS; upon preparation of the contents transport, performing the steps of transporting a command depending on each environment between the DMP and the DMS, controlling contents transport in the IEEE 1394 interface, and linking the contents transport between the DMP and the DMS; and upon ending of the contents control and transport, performing the steps of transporting a “DISCONNECT” command between the DMP and the DMS using the protocol, performing a cleanup between the DMP and the DMS, and ending the contents transport.

Abstract: A method for operating a computer network includes: a become_root_primary command is issued to a first router to set an ID so that a spanning tree protocol (STP) selects the first router as a primary root router; a become_root_secondary command is issued to a second router to set an ID so that STP selects the second router as a secondary root router; transitioning, in response to failure of the first router, the second router to become the root router. An enable_uplinkfast command is issued to a router, and the router selects a backup designated port for a designated port, and selects a backup root port for a root port. Ports transmit BPDU messages as heartbeat messages, and a failure to detect the BPDU messages results in a backup port assuming the role of a port not detecting the BPDU messages.

Abstract: An Internet group membership protocol (IGMP) network device and a signal processing control method thereof in an Internet protocol (IP) digital broadcasting system are provided. The method includes: when an IGMP packet is received from an IGMP client, determining, at a packet transmission/reception unit, whether or not the received IGMP packet is transmitted via bypass; when it is determined that the IGMP packet received from the IGMP client is transmitted via bypass, copying, at the packet transmission/reception unit, the received IGMP packet and bypass-transmitting an original IGMP packet to an upper IGMP network device; transmitting, at the packet transmission/reception unit, the copied IGMP packet to a host; and receiving, at the host, the IGMP packet from the packet transmission/reception unit, processing the IGMP packet, and simultaneously updating its multicast table and a multicast table of the packet transmission/reception unit.

Abstract: A method of providing network access across a shared communications medium between competing users includes the step of allocating network access for each user for a future time interval. Features include forecasting network access of the users in a future time interval, and prioritizing the users for allocating network access to the users. The network access allocations represent network access allowances available to the users during the future time interval, and further may represent network access usage. Classes of users can be allocated network access first, and then each user allocated network access from the class allocation. Users with high network access usage are identified and solicited to modify service level agreements under which network access is provided. Network Access is also provided to user classes under class service level agreements entered into, for instance, by a service provider on behalf of the users.
