Abstract: Generating traffic in a network environment. A traffic generator can be used to record the low level network data that is generated in response to high level user input. The traffic generator can receive instructions that identify when to start and stop recording network instructions. Once started, the high level user input is converted into low level network data and recorded. The recorded low level data thus reflects real usage and can be used to generate virtual traffic. The virtual traffic can be processed such that it represents multiple users. The response of the network or of network components to the virtual traffic can then be monitored and analyzed.

Abstract: Generating traffic in a network environment. A traffic generator can be used to record the low level network data that is generated in response to high level user input. The low level network data can be processed to simulate multiple virtual users. Once the network data is processed, the virtual data can be sent over a network as if multiple users were using the network. The response and functionality of the network and of network components can then be monitored and evaluated based on the response to the virtual data.

Abstract: Disclosed is a method and apparatus for dynamically adjusting the playout delay for audio signals, which mainly includes three parts of dynamic adjustment, i.e., playout delay, silence length, and jitter buffer size. In the invention, the time for playout delay is real-time adjusted according to the probability distribution of the number of packets buffered in a jitter buffer. A voice detection is taken to detect silence within a voice packet. By dynamically adjusting the silence length in the voice packets, the present invention reduces the network variation impact on the voice quality. It also overcomes the drawback of conventional techniques for estimating playout delay, and reduces the whole computation complexity of the playout delay for the voice packets.

Abstract: Systems and methods are described for a plurality of telephony devices that have no central telephony call processing services (server-less) to discover each other in a peer-to-peer manner.

Further still, the method also allows the packet network telephony devices to operate cooperatively with centralized telephony call processing services.

Abstract: In a wireless communication system, dynamic payload header suppression (DPHS) is applied to a data stream to reduce header overhead. DPHS allows the suppression of static fields as well as fields that change in a predictable manner (i.e., predictably dynamic fields). To suppress predictably dynamic fields, delta encoding is utilized to enable a cable modem to replace a dynamic field with information indicating how the field is different from the same field in a previous packet in the data stream. DPHS constructs a suppression mask by using a special packet called a “learn” packet. The “learn” packet is a copy of the original packet with extra bytes that guide the suppression process. It indicates that both the sending and receiving entities are to take a full copy of a packet header, which is then used as a reference to reconstruct the suppressed fields.

Abstract: A multi-hop mesh network may be connected to a Local Area Network (LAN) using a MAC Bridge. One or more nodes on the mesh network may be configured as a bridge node that employs a MAC bridge. Packets that travel between stations on the LAN to nodes on the mesh network flow through one of the bridge nodes on the mesh network. The bridge nodes do not receive all the packets on mesh network, but they receive the packets that are to be transmitted across the MAC bridge. As the bridge nodes learn of new stations on the LAN they advertise routes to the other nodes within the mesh network specifying how to reach those stations. This enables MAC Bridge functionality between wireless mesh networks and 802 LANs.
