Research On Technology Of Integrating 10 Gigabit Ethernet With SUPANET

The general background of this thesis is the technology of 10 Gigabit Ethernet and the research on the Next Generation Internet (NGI) architecture called Single physical layer User-data switching Platform Architecture Network (SUPANET) at Sichuan Network Commnication Technology Key Laboratory (SC-Netcom Lab).In order to make full use of the bandwidth of the backbone networks, DWDM technology have been used at present, but the low-bandwidth of access networks make the bottleneck problem prominent gradually. The high-speed 10Gigabit Ethernet can meet the demand for new capacity to resolve the bottleneck problem between low-bandwidth access and high-bandwidth transmission spanning a wide range of applications with backwards compatibility . The most advantage of SUPANET is the concept of out-band signaling and the high-speed switching technology called Ethernet-oriented Physical Frame Timeslot Switching (EPFTS). SUPANET can provide the convenient, high-performance, services with QoS guarantee. So, 10 Gigabit Ethernet integrating with SUPANET extends the scope of SUPANET and brings the services with end-to-end QoS guaranty to users.For the interconnection and intercommunication between 10 Gigabit Ethernet and SUPANET, A solution called EPF-over-10G is presented to make use of Integration Sublayer to achieve the 10 Gigabit Ethernet integrating with SUPANET. With the principle of Ethernet switching and the Out-band signaling concept of SUPANET, the solution of integration techniques includes appending an Integrated Sublayer in U-platform and improving the establish/delete connection protocol in Signaling control and Management Platform (S&M-platform). A new term "virtual MAC address" is presented to identify different services connection during the progress of the virtual connection establishment in order to build the relationship between Virtual Link Indentifier (VLI) and MAC address. When the virtual connection is done, the Ethernet-oriented Physical Frame (EPF) is decapsulated to a MAC frame, then, it is forwarded by searching switch table through virtual MAC address in Ingtegration Sublyaer. When this frame is received in destination, it will be encapsulated to EPF frame again through the information carried by virtual MAC address. For traditional Ethernet MAC frame, it is forwarded by destination MAC address directly as the Integration Sublayer being absent.A simplified network topology structure is established with OPNET to simulate the EPF-over-10G solution. The simulation focuses on the EPF encapsulation/decapsulation and the data transmission process in U-platform, the progress of establish the connection, reserve resource and release the connection in S&M-platform, and the 64B/66B coding used by Physical Coding Sublayer (PCS) in Physical Layer of 10 Gigabit Ethernet. The simulation results reveal that the EPF-over-10G solution is correct and feasible.
