[Abstract]:Hybrid Fiber Coax Network hybrid fiber coaxial hybrid network for CATV system HFC network has the characteristics of easy to realize bidirectional transmission and large transmission capacity. The DOCSIS Data-Over-Cable Service Interface Specifications cable data service interface specification based on HFC network is widely used in North America because of its high communication rate, support for multiple services and strong configuration management ability. In order to meet the domestic application scenarios and business requirements, a C-DOCSIS China-DOCSIS is proposed on the basis of DOCSIS in China, which inherits the technical advantages and technical assets of the HFC DOCSIS technology architecture and simplifies some channel technologies. This paper focuses on the design and performance analysis of MAC Access Control layer protocol simulation platform for C-DOCSIS. Firstly, the network structure, protocol stack and physical layer processing flow of C-DOCSIS protocol are introduced. The frame structure of MAC layer, data transmission mechanism (including channel binding, competition mechanism) and protocol encapsulation method are analyzed in detail. On this basis, the protocol simulation platform of C-DOCSIS MAC layer is designed. The Event-based simulation platform architecture and statistics, data packet sending, receiving, queue management and channel planning are implemented. Based on this platform, the MAC protocol mechanism is simulated, and various test scenarios are designed. The performance of the protocol, such as throughput, delay and delay jitter, is tested and analyzed.
