Claim 0:
1. A method of header compression processing, comprising:
sending, by a first device, an Ethernet frame on which Ethernet header compression is not performed to a second device, wherein the Ethernet frame on which the Ethernet header compression is not performed comprises full Ethernet header information;
sending, by the first device, an Ethernet frame on which the Ethernet header compression is performed to the second device, wherein the Ethernet frame on which the Ethernet header compression is performed comprises compressed Ethernet header information;
wherein the full Ethernet header information comprises the following: context identifier information for identifying a context to which the full Ethernet header information is applicable; a first indication information for indicating that the Ethernet header information in the Ethernet frame is full; and
wherein the compressed Ethernet header information comprises the following: context identifier information for identifying a context to which the compressed Ethernet header information is applicable; a second indication information for indicating that the Ethernet header information in the Ethernet frame is compressed;
further comprising:
receiving, by the first device, first feedback information sent by the second device after sending an Ethernet frame on which the Ethernet header compression is not performed to the second device, wherein the first feedback information is used for indicating whether the second device correctly receives the Ethernet frame on which the Ethernet header compression is not performed and which is sent by the first device;
wherein the first feedback information comprises:
first context identifier information for representing a context to which the Ethernet header information is applied.
