Abstract: An embodiment of the exemplary SoftRouter architecture includes two physically separate networks, a control plane network and a data plane network. The data plane network is one physical network for the data traffic, while the control plane network is another physical network for the control traffic. The topology of the data plane network is made up of interconnected forwarding elements (FEs). The topology of the control plane network is made up interconnected control elements (CEs). This physical independence of the control plane network from the data plane network provides for a secure mechanism to communicate among the CEs in the control plane network. In addition, this physical independence provides improved reliability and improved scalability, when compared to the traditional router architecture, where control plane message are in-band with the data plane.

Abstract: A network architecture includes one or more feature servers and control servers in a control plane that is logically separate from a data plane that includes forwarding elements. Feature servers facilitate adding network-based functionality in a centralized way that is has better scalability than the traditional router architecture. Some examples of network-based functionality are voice over IP, enhancing QoS support, scaling BGP route reflectors, network-based VPN support, scaling mobile IP support, introducing IPv6 into existing and future networks, and enhancing end-to-end network security. Feature servers remove complexity from routers, allow functions to be implemented on a standard-off-the-shelf server platform, facilitate easy introduction of value-added functions, and scale well.

Abstract: The invention includes a method and apparatus for providing multimedia content to a plurality of wireless terminals. The method includes transcoding an original media stream to form at least one companion media stream, each media stream having a different data rate, and advertising each media stream to each of the plurality of wireless terminals, each wireless terminal having an associated channel condition. The original media stream and at least one companion media stream are each adapted for being selected by each of the wireless terminals. For each wireless terminal selecting one of the media streams, the selected one of the media streams is selected using the data rates of the media streams and the channel condition of the wireless terminal. The transcoding of the media stream to form the at least one companion media stream may be performed using channel condition information.

Abstract: The invention includes a method and apparatus for providing multimedia content. The method includes receiving, at a network element having a first buffer, a data stream conveying a media clip having an associated media bit rate, the media clip intended for transmission toward a wireless terminal having a second buffer, and transmitting the data stream toward the wireless terminal at a media transmission rate determined according to a data rate supported by a radio access network over which the data stream is transmitted toward the wireless terminal. The buffers bridge a mismatch between the media bit rate and media transmission rate. The wireless terminal may select one of a plurality of presentation modes, where the selected presentation mode controls streaming of the media clip to the wireless terminal and presentation of the media clip at the wireless terminal.

Abstract: The SoftRouter architecture separates the implementation of control plane functions from packet forwarding functions. In this architecture, all control plane functions are implemented on general purpose servers called the control elements (CEs) that may be multiple hops away from the forwarding elements (FEs). A network element (NE) or a router is formed using dynamic binding between the CEs and the FEs. The flexibility of the SoftRouter architecture over conventional routers with collocated and tightly integrated control and forwarding functions results in increased reliability, increased scalability, increased security, ease of adding new functionality, and decreased cost.

Abstract: The new zooming feature of the present invention applies to video service on mobile phones. The feature offers more interaction between the end user and the video server and it provides more interesting viewing. It has the potential to become a service differentiator for video services provided by wireless service providers. Because the bandwidth required for the streams does not change, the only complexity incurred is the control message processing and the only extra storage required is at the video server or the proxy.

Abstract: A system that enables end-to-end networking within CDMA oriented networks. Several base stations operating within the CDMA oriented network simultaneously receive data from the same mobile unit. A distributed algorithm operating within each of the base stations monitors the reception of the data from the mobile unit, as well as commands/instructions from other base stations. One of the base stations is appointed as a dominant base station. The appointment of a dominant base station can be done randomly or based on the quality of data being received by the base station. When the dominant base station detects a decrease in the quality of received data from the mobile unit, the dominant base station instructs the remainder of the base stations to forward any data received from the mobile to the dominant base station.
