Abstract: A method for managing UMA communications within a local area network and a network controller includes establishing a first connection between a first UMA device and a LAN-based UMA network controller (LAN-UNC) and establishing a second connection between a second UMA device and the LAN-UNC. The first and second connections are carried over the local area network. The first and second UMA devices are connected to the same local area network. The method provides establishing a third connection between the LAN-UNC and a UMA network controller (UNC). The UNC is connected to an external network and the third connection extends over the external network. The method includes transporting packets received using the first and second connections to the UNC using the third connection. Packets received using the third connection are transported to the first UMA device using the first connection and to the second UMA device using the second connection.

Abstract: A system processes media, such as voice and video, in a scalable and secure manner. The system can process voice and video for a large quantity of users. For example, the system can enable large quantities of simultaneous phone conversations over an IP network. The IP network can carry voice, video, and other data concurrently. The system identifies which packets carry voice data, which packets carry video, and which packets carry other kinds of data. The system scales both with the quantity of users and in terms of network topology. Multiple digital signal processors (DSPs) can be controlled by and connected to a switching device via an Ethernet network. One or more DSPs connected to the switching device interact with the switching device as separate IP devices, in that each such DSP may have its own separate IP address to which IP packets may be addressed.

Abstract: The present invention relates to methods, apparatuses, and systems for relaying data involving obtaining a data stream from a data source, forwarding the obtained data stream over a network, while forwarding the obtained data stream over the network, monitoring the obtained data stream to detect a data transfer mode associated with inclusion of synchronization characters in the obtained data stream, and if the data transfer mode is detected, removing a plurality of synchronization characters from the obtained data stream to produce a bandwidth-reduced data stream and forwarding the bandwidth-reduced data stream instead of the obtained data stream over the network. Synchronization characters may comprise start bits, stop bits, and idle bits. The data transfer mode may be an asynchronous data transfer mode based on a V.14 standard. Also, the asynchronous data transfer mode may be detected by decoding a predetermined number of valid V.14 frames from the obtained data stream.

Abstract: A recovery chunk is generated based on information found in each chunk in a group of chunks. For example, the group of chunks includes three chunks of which information in the three chunks is used to generate a recovery chunk. The recovery chunk is then used to recover a single lost chunk in the group of chunks. The three chunks and the recovery chunk are sent to a receiver over a network. If one of the three chunks is lost, the recovery chunk is used to generate the lost chunk. The recovery chunk is used to recover a single lost chunk, however, the recovery chunk is not used to recover more than one lost chunk in the group. The number of chunks is also dynamically adjusted based on chunk loss at a receiver. This adjustment is based on the bandwidth used and reliability desired.
