Abstract
There is provided a system and method for compressing voice-over-IP headers. More specifically, in one embodiment, there is provided a method comprising receiving a voice-over-IP packet including at least one packet header that contains a set of one or more packet header field values, selecting a content identifier that corresponds to the one or more packet header field values of the received packet, replacing at least one of the packet-header field values in the received packet with the selected content identifier, thereby to create a compressed voice-over-IP packet, and transmitting the compressed voice-over-IP packet across a network connection.
Claims20
A method comprising:
- receiving a voice-over-IP packet including at least one packet header that contains a set of one or more packet header field values;
- selecting a content identifier that corresponds to a location in a database of a mapped value corresponding to the one or more packet header field values of the received packet;
- replacing at least one of the packet-header field values in the received packet with the selected content identifier, thereby to create a compressed voice-over-IP packet;
- and
- transmitting the compressed voice-over-IP packet across a network connection.
A device configured to transmit voice-over-IP packets, the device comprising:
- a first compressor configured to:
- receive a voice-over-IP packet including at least one packet header that contains a set of one or more packet header field values;
- select a content identifier that corresponds to a location in a database of a mapped value corresponding to the one or more packet header field values of the received packet;
- replace at least one of the packet-header field values in the received packet with the selected content identifier, thereby to create a compressed voice-over-IP packet;
- and transmitting the compressed voice-over-IP packet across a network connection.
A tangible machine readable medium comprising:
- code adapted to receive a voice-over-IP packet including at least one packet header that contains a set of one or more packet header field values;
- code adapted to select a content identifier that corresponds to a location in a database of a mapped value corresponding to the one or more packet header field values of the received packet;
- code adapted to replace at least one of the packet-header field values in the received packet with the selected content identifier, thereby to create a compressed voice-over-IP packet;
- and
- code adapted to transmit the compressed voice-over-IP packet across a network connection.
