RoHC & RoHCv2 Back to Exhibitor Page
Robust Header Compression (RoHC) serves for optimizing real time data by compressing the headers of multiple layers down to a minimum. Especially in wireless networks with high error probabilities and scarce resources, RoHC and RoHCv2 are the best choice to compress the overhead of IP, IPv6, UDP or RTP data.
3GPP has chosen RoHC and RoHCv2 for compression cellular networks. For satellite systems, the robustness and compression ratio of RoHC or RoHCv2 are an important benefit to save cost in TDD transport.
RoHC follows a peer-to-peer concept, allows transporting the compressed data over any lower layer, and can be treated as a transparent compression entity that just eliminates overhead before it congests the network.
