摘要:
A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and determining whether one or more samples included in the flow should be suppressed. The method further includes suppressing a selected one or more of the samples if the selected samples are similar to previously received samples and interleaving one or more voice data segments associated with a voice call into outgoing Internet protocol (IP) traffic flows. In more particular embodiments, packets that do not come in from a GSM port on the cell site element are designated as default best effort (BE) traffic.

A method for communicating data is provided that includes receiving a plurality of cells associated with a communications flow and determining whether one or more of the cells included in the flow should be suppressed, whereby a selected one or more of the cells are suppressed. The method also includes identifying cells that cannot be suppressed and suppressing portions thereof.

A signaling network node is configured for identifying a received signaling message as belonging to one of a plurality of prescribed originating node groups, based on prescribed message class selection criteria. Each originating node group has at least one originating node and is assigned at least one congestion threshold relative to a message rate (e.g., messages per unit time or number of bytes per unit time). The signaling network node determines the message rate for each corresponding originating node group; if the message rate for an originating node group exceeds the corresponding at least one congestion threshold, the signaling network node outputs a congestion signaling message to the originating node having sent the signaling message, for reduction of the corresponding message rate.

A hierarchical wide-area network architecture which conforms to the DLSw protocol is provided, in which multiple routers having a logical connection to one another are designated as a peer group. At least one router in each peer group is designated as a border peer, and functions as a gateway between the members of its group and other peer groups. The peer group structure reduces broadcast traffic on slow links by changing the source of the broadcast from a small access router with a relatively slow link to another, more powerful router, with a faster link on the network. More than one border peer can be included in each group, to share the transmission workload and act as a backup. The border peers can share information about the groups that they service and can cooperate to provide a single-point broadcast service to all of the users of the service. When two or more routers are connected to a network in parallel to provide back-up facilities, conditional filters are employed to prevent redundant operations. Different types of frames are handled by the two different routers, so that they share the communication load between them and make the most effective use of the available bandwidth.

A method for communicating data is provided that includes receiving a plurality of cells associated with a communications flow and determining whether one or more of the cells included in the flow should be suppressed. In specific embodiments, the method further includes suppressing a selected one or more of the cells associated with asynchronous transfer mode (ATM) adaptation layer 5 (AAL5).
摘要:
A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and determining whether one or more samples included in the flow should be suppressed. The method also includes suppressing a selected one or more of the samples if the selected samples are similar to previously received samples. In a more particular embodiment, the method also includes positioning unique samples that are included in the flow in a super-frame to be communicated to a next destination. Additionally, the method may include receiving the unique samples and evaluating the unique samples in order to restore a plurality of bits associated with the communications flow.

A method for operating a computer network has a source router transmit a first message to be received by an intermediate router of the computer network, the first message to activate the intermediate router to listen for a designated time period for the intermediate router to receive a second message. Upon receiving a second message by the intermediate router during the designated time period, the intermediate router responds to the second message in response to receiving the second message during the designated time period.
摘要:
Backup peers in an asymmetrically organized computer network are organized into a "pool" of available devices that are activated as necessary. The network comprises a set of remote peers and a set of local peers directly associated with a central computational facility, the local peers facilitating connection between the remote peers and the central facility. During the capabilities exchange, the "primary" local peer to which the remote peer connects provides a list of backup peer devices to the remote peer. If the primary peer fails (or if the rate of message exchange falls below some predetermined threshold), the remote peer can use the backup information to access a backup peer from the pool. The invention allows each backup peer to be assigned to multiple remote peers, with the total number of backup peers determined by aggregate backup utilization (rather than simply assigning an individual backup peer to each primary peer regardless of whether such a high level of redundancy is justified).
