The present invention provides an adaptable codec for use in a communication system. The adaptable codec is capable of encoding a digital stream to be transmitted according to any one of a number of encoding schemes. A particular encoding scheme may be selected based on information received from a network entity that is separate from the communication system, a user associated with the communication system, a remote communication system with which communications are established, or a combination thereof. Once a particular encoding scheme is selected, an encoder will encode the digital stream to be transmitted, and a packet processor will create packets from the encoded digital stream. The selection of an encoding scheme will generally correspond to a desired quality of experience level.

Adaptable codec for selecting encoding scheme based on quality of experience

The present invention allows primary communication sessions that are established between two communication clients to be monitored, wherein such monitoring occurs without the knowledge of the communication clients. An intercept tunnel is created between an intercept server and an access concentration point, which supports at least one of the communication clients over an access network. The access concentration point and the intercept server will cooperate to allow the communication session to be established, wherein a portion of the communication session will be established over the intercept tunnel. A first communication session is established with the first communication client through the access concentration point, a portion of it provided via the intercept tunnel. A second communication session is established with the second communication client. The intercept server will essentially receive and forward traffic to and from the first and second communication clients over respective first and second communication sessions.

Peer-to-peer communication session monitoring

The present invention facilitates identification and control of peer-to-peer sessions via an access concentration point (ACP). The ACP will monitor packets routed therethrough and detect access messages intended for known peer-to-peer access services. The access messages sent from a communication client to the peer-to-peer access service, which will respond by sending an access reply message back to the communication client. The ACP will monitor the packets being routed to identify the access reply message, which will include routing addresses that may be associated with potential remote communication clients. With these addresses, the ACP can monitor packets to identify when an attempt to initiate a peer-to-peer communication session is being made to or through an entity associated with one or more of these addresses. Upon detecting a session initiation message to or through an identified address, the ACP may take any number of actions, depending on how the ACP is configured.

Identifying and controlling network sessions via an access concentration point

The present invention inspects packets to identify session initiation messages associated with select applications. A session initiation message may be any message used to initiate a communication session with another communication client. Once a session initiation message from a select application is identified, the intended communication session may be identified, monitored, prevented, or otherwise processed in a predefined manner. These select applications may be illicit applications from which communication sessions are actually or potentially unlawful or otherwise improper. The illicit communication sessions that the present invention seeks to control may be used for voice communications as well as for transferring data and facilitating application collaboration, such as is used in video conferencing or file sharing. The session initiation messages need not be received directly from the originating communication client for inspection. Packet inspections may take place at any location, such as aggregation points throughout the packet networks.
