Ethernet is the dominant computer networking technology for local area networks. It has replaced other competing wired LAN technologies. There are many benefits in connecting two separate LANs by simply extending the Ethernet link between the two networks instead of routing the packets over another network. For example, a UHF/VHF link used to connect two LANs. But in this case, Ethernet header itself becomes a significant overhead when payload is small.
Effnet EthHC™ can efficiently compress the Ethernet header. It is best used in the two end-points of the link connecting two LANs carrying Ethernet frames. It is designed to work in perfect symbiosis with the Effnet ROHC™ product portfolio. As shown in figure 1, this combination can save a significant amount of bandwidth by compressing Ethernet headers along with compression of IP/UDP/RTP, IP/UDP, IP/TCP and IP/ESP headers.
Above shows an example of traffic compressed using Effnet EthHC™ and Effnet ROHC™.
|Traffic type||Avg. pkt size w/o. ROHC* (bytes)||Pkt size w. ROHC (bytes)||Pkt size w. ROHC and EthHC (bytes)||Savings w. ROHC (%)||Savings w. ROHC and EthHC (%)|

The classification and context management is an essential component of header compression function.
