Abstract: A first header compression table for compressing a message header is generated based on a first communication connection established between communication apparatuses. A message is transmitted from a communication apparatus to another communication apparatus based on the first communication connection, and a header of the message has been compressed based on the first header compression table. It is determined whether the first header compression table is used as a second header compression table for compressing a message header to be communicated based on a second communication connection which is different from the first communication connection and has been established between the communication apparatuses. The header of the message to be communicated based on the second communication connection is compressed using the first header compression table as the second header compression table in accordance with the determination.

Abstract: A single virtual telephone number that is used to route telephony communications is assigned to first and second users if the first and second users rarely, if ever, communicate with the same party. When an incoming call is received on the virtual telephone number, telephony information for the first and second users is reviewed to determine if the calling party is one that has communicated with either of the first and second users in the past. If so, the telephony communication is routed to the user who has communicated with the calling party in the past.

Abstract: By way of a non-limiting example, a server resource receives portions of a non-adaptive bit rate data stream. The server resource also receives portions of an adaptive bit rate data stream. The server resource interleaves the portions of the adaptive bit rate data stream and the portions of the non-adaptive bit rate data stream onto the multi-stream data channel.

The distribution resource, in turn, transmits the adaptive bit rate data stream and the non-adaptive bit rate data stream to a group of multiple subscribers that have shared access to communication link in a cable network environment.
