Method for transmitting compressed data in packet-oriented networks
First Claim
Patent Images
1. A method for transmitting compressed data in data packets from a first network node device to a second network node device, comprising:
- checking a compression state for the data contained in the data packets;
evaluating a database entry characterizing the second network node device; and
modifying message header entries in the data packets on the basis of the database entry and on the basis of the compression state, to thereby produce modified packets; and
forwarding the modified packets from the first network node device to the second network node device.

Abstract
The method transmits compressed data in packet-oriented networks. Before data packets are forwarded to a second network node device, a first network node device is used to check a compression state for the data contained in the data packets. In addition, a database entry characterizing the second network node device is evaluated. Message header entries in the data packets are modified on the basis of the characterizing entry and on the basis of the presence of the compression state.

18. A first network node device for transmitting data packets to a second network node device in a packet-oriented network, comprising:
-
an evaluation unit to check a compression state for data contained in the data packets and to evaluate a database entry characterizing the second network node device;
a compression/decompression unit to modify message header entries in the data packets on the basis of the database entry and on the basis of the compression state, to thereby produce modified data packets; and
a transmission unit to forward the modified data packets from the first network node device to the second network node device. - View Dependent Claims (19, 20)
