A system architecture and methods for data traffic flow classification are provided. An initial traffic class is assigned to a data flow as a current traffic classification, where the initial traffic class is based static traffic classification method(s) applied with respect to an initial packet of the data flow. A predetermined number of further packets of the data flow, subsequent to the initial packet, are analyzed based on predetermined factor(s), and a traffic class based on the analysis of the further packets is determined. The traffic class based on the analysis of the further packets is assigned as the current traffic classification of the data flow. Data indicating a traffic class for the data flow (based on a dynamic traffic classification method) is received, and the traffic class based on the dynamic traffic classification method is assigned as the current traffic classification of the data flow.

Apparatus and method for staged traffic classification among terminal and aggregation nodes of a broadband communications system

A method for traffic management and resource allocation on a shared access network including estimating a bandwidth capacity of a gateway, determining a demand rate of an IP gateway, allocating bandwidth to the IP gateway based on the demand rate, traffic priority, or traffic weighting, allocating bandwidth to the IP gateway in advance of demand when excess bandwidth is available, scheduling traffic at the IP gateway based on traffic priority, service plan of a VSAT, or physical layer properties of the VSAT, performing priority queue servicing of traffic at a gateway using a real time traffic priority queue, a non-real time traffic priority queue, two or more modulation and coding queue groups, and a code block queue.

Method and system for traffic management and resource allocation on a shared access network

A method for controlling data traffic with random early detection and window size adjustments including performing random early detection on incoming data packets, calculating a simple moving average of packet dropping probabilities for the data packets as calculated when performing random early detection, decreasing an advertised window size if the simple moving average is greater than a probability target plus a tolerance factor, increasing the advertised window size if the simple moving average is less than the probability target minus a tolerance factor, and not adjusting the window size if the simple moving average is not greater than a probability target plus a tolerance factor and not less than a probability target minus a tolerance factor.

Method and system for controlling TCP traffic with random early detection and window size adjustments

A method for inroute bandwidth allocation supporting multiple traffic priorities in a satellite network including generating a backlog report, transmitting the backlog report to an inroute group manager, receiving a bandwidth allocation from the inroute group manager, and servicing priority queues and transmitting data to a satellite based on the bandwidth allocation from the inroute group manager.

Method and system for inroute bandwidth allocation supporting multiple traffic priorities in a satellite network

An approach for providing flow control in a radio communication system is disclosed. A request from a non-satellite system specific side of a transport interface is made to a system specific side of the transport interface for a flow control allocation that specifies an amount of data to be stored in a queue of the system specific side of the transport interface. The system specific side supports a signaling function that is based on a transmission characteristic of the radio communication system. The flow control allocation is generated based upon availability of the queue, wherein the destination address is a link layer address of the satellite communication system. This arrangement has particular applicability to a satellite network (e.g., Very Small Aperture Terminal (VSAT) network) that provides data communication services.

An approach is provided for supporting retrieval of web content over a meshed communication network (). A first server () receives a request from a browser application () for the content resident in the web server (). The first server () includes a downstream proxy () configured to modify the request to include information specifying support of a parse and pre-fetch service within an optional header field of the request as to permit handling of the modified request by the web server () in absence of an upstream proxy () that is communicating with the web server (). A second server () is configured as the upstream proxy () to intercept the modified request and pre-fetch the content from the web server (). The second server () forwards the pre-fetched content over the communication network () to the first server (). This approach has particular applicability in relatively high latency networks, such as a satellite communications system.

Method and system for providing enhanced performance of web browsing

An approach for routing over a radio network is provided. A terminal receives a packet over the radio network, which supports meshed connectivity, wherein the packet is destined for a destination host. The terminal determines whether the destination host is reachable by a communication interface based upon a route table, and selectively redirects the packet over the radio network according to the route table. A route server is provided to collect routes from the terminal as well as other terminals within the radio network. The route server then disseminates the collect routes to the terminals for updating of their respective route tables. The present invention has particular applicability to a fully meshed satellite network.

System and method for routing among private addressing domains

An approach for transmitting packets conforming with the TCP (Transmission Control Protocol) over a satellite communications network comprises a plurality of prioritized queues that are configured to store the packets. The packets conform with a predetermined protocol. A classification logic classifies the packets based upon the predetermined protocol. The packet is selectively stored in one of the plurality of queues, wherein the one queue is of a relatively high priority. The packet is scheduled for transmission over the satellite communications network according to the relative priority of the one queue.
