Abstract: A signature-based traffic classification method maps traffic into preselected classes of service (CoS). By analyzing a known corpus of data that clearly belongs to identified ones of the preselected classes of service, in a training session the method develops statistics about a chosen set of traffic features. In an analysis session, relative to traffic of the network where QoS treatments are desired (target network), the method obtains statistical information relative to the same chosen set of features for values of one or more predetermined traffic attributes that are associated with connections that are analyzed in the analysis session, yielding a statistical features signature of each of the values of the one or more attributes. A classification process then establishes a mapping between values of the one or more predetermined traffic attributes and the preselected classes of service, leading to the establishment of QoS treatment rules.

Abstract: A system and method for dynamic egress routing through a default gateway in a network is disclosed. One aspect of the present invention includes providing a default gateway that manages routes to Internet egress points for a client. The default gateway includes a list of Internet egress points that correspond to the default gateway. A metric is applied to the list to determine the optimal path to an Internet egress point. The default gateway uses the optimal path to manage Internet access routing for the client. Another embodiment includes a system for managing routing to Internet egress points on a network having a default gateway configured to route data packets between the Internet egress points and a client. The default gateway determines the optimal path to the Internet egress points.

Abstract: One embodiment relates to a method by a switch of tracing a broadcast path from the switch through a group of switches. A broadcast traceroute packet is issued with a first hop entry from each port within the broadcast path. Trace hop packets are received from hop switches within the broadcast path, and trace complete packets are received from end switches within the broadcast path. Other embodiments are also disclosed.

Abstract: A re-multiplexer module for use in a packet processing system used in cable television headend devices generates two or more output streams from two or more MPEG input transport streams. The re-multiplexer module includes an input processing portion that receives a plurality of input data streams containing packet data, a plurality of packet buffers to store the packet data, an output processor that selectively multiplexes the data packets in the packet buffers, and a host processor that controls the operation of the input processing portion and the output processing portion.

Abstract: A Base Station Controller (BSC) that reduces the occurrence of audible noise in a Code Division Multiple Access (CDMA) radio network is provided. The BSC according to one embodiment of the present invention comprises a Media Stream Board (MSB) for compressing groups of 160 PCM speech samples from a Public Switch Telephone Network (PSTN) into vocoded frames, and a Special Purpose Board (SPB) for reformatting the vocoded frames from the MSB into over-the-air CDMA vocoded frames. The MSB and SPB each have a local timer that is slave to “PSTN time”. The BSC further comprises a Timing Unit Board (TUB) connected to a GPS receiver. The TUB receives “GPS time” from the GPS receiver. The TUB generates timing cells, each containing time-of-day information according to “GPS time”. The TUB distributes the timing cells to the MSB and the SPB over an Asynchronous Transfer Mode (ATM) network. The MSB and SPB use the received timing cells to compare their local timer, which tracks “PSTN time”, to “GPS time”.

Abstract: A method (500) and a mobile station (160) for controlling bearer assignment are described herein. In a wireless communication system (100), a core network (210) is configured to provide communication services to the mobile station (160). The mobile station (160) may detect a resource conflict associated with a communication service within the mobile station (160). Upon detecting the resource conflict, the mobile station (160) may determine a condition of the resource conflict suggesting to delay a bearer assignment for the communication service. Based on the condition of the resource conflict, the mobile station (160) may transmit a request associated with the bearer assignment to the core network (210).

Abstract: A subscriber unit (104) listens to a first channel (202) comprising a plurality of micro-slots and a plurality of data units. The subscriber unit decodes at least a portion of a data unit on the first channel comprising a micro-slot value. The subscriber unit learns the synchronization between the first channel and a second channel (206/300) based on the micro-slot value. A first base radio (1061) transmits a first plurality of data units on the first channel. A second base radio (1063) transmits a second plurality of data units on the second channel. The first plurality of micro-slots on the first channel are synchronized with the second plurality of micro-slots or plurality of frame boundaries on the second channel. The first base radio transmits a message (406) on the first channel in at least one of the plurality of data units, wherein the message comprises at least a micro-slot value used to associate the synchronization between the first channel and the second channel.

Abstract: A method and apparatus of adjusting a search window size by a remote unit in a slotted mode wireless communication system. In a slotted mode communication system, the remote unit is in an “active state” during its assigned slot. While in the active state the controller in a remote unit passes selected sets of search parameters to a search engine. The search engine performs searches on base stations using the selected sets of search parameters. One search parameter, the search window size, is adjusted in response to a measured signal strength of a first base station signal. The adjusted search window size is used by the remote unit when searching other base stations.

Abstract: STTD encoding is signal processing carried out when a base station performs diversity transmission in open-loop mode to a mobile station. The STTD encoding method according to the present invention applies reverse STTD encoding on a pilot signal that should not be subjected to STTD encoding beforehand. Then, the multiplexer time-multiplexes the pilot signal with transmission data and control data to compose a transmission frame. Then, all data included in the transmission frame is subjected to STTD encoding. Applying reverse encoding before frame composition eliminates the need for distinguishing data to be encoded from data not to be encoded during STTD encoding.
