The distributed networks will be lower performance and harder to management when the network topology expansion in the public network. The iconic network businesses: Google、Yahoo and Facebook start into research and development the SDN(Software Defined Networking) for improve the network efficiency and simplify the network management system. Network intelligence is centralized in SDN that maintain the network, the SDN also provide the programmatically configured. The SDN for the enterprises and network data centers can get the benefit of the network automated and dynamically adjust network-wide traffic flow to meet changing needs. The SDN switch need the faster but more expensive TCAM(Ternary Content Addressable Memory) for the SDN flow table or refresh the network data and access data constantly. In order to lower the SDN switch cost, it always need to limit the TCAM size of the switch, when the flow entries exceed the TCAM maximum size, the SDN switch must need to remove the lower priority flow entry automatically, it will let the SDN TCAM’s rule space get lower efficiency. This thesis is using the ROHC to compress the network packet’s head for reduce the TCAM size usage. The ROHC will improve the TCAM efficiency but no need increase the SDN switch cost base on the same TCAM size, it still can let network work stable, higher flow entry rate and reduce the network traffic. |
