Reordering Method for HIMAC 3.0 Deframing in 10 Gigabit Coaxial Broadband Access Network
摘要
Abstract
High-performance coaxial cable network technology is a hybrid fiber-coaxial access technology that has evolved to the third generation.To achieve the access rate of Gigabit Ethernet,the third-generation HINOC(High Performance Network Over Coax)has introduced a multi-channel bonding mechanism.However,while this mechanism effectively expands the channel bandwidth of the HINOC network,it is likely to cause out-of-order data reception at the HIMAC(HINOC Media Access Controller)frame disassembling end.In view of this problem,this study proposes a frame disassembling and reordering method.By designing and implementing key technologies such as reordering queue cache management,enqueue logical address calculation,timeout judgment and clearing,as well as dequeue judgment,the problem of out-of-order frame disassembling caused by the multi-channel bonding mechanism is solved.Moreover,the key functional points are verified through simulation and board-level verification.The experimental re-sults show that the proposed method can effectively handle the out-of-order problem caused by multi-channel bond-ing,and can ensure the stable operation of the system in case of error situations,with strong robustness,meeting the functional and performance requirements of HIMAC 3.0 for Gigabit coaxial broadband access.关键词
