Communications highway network system

摘要: A communications highway network system for the interactive communication of digital and analog information that incorporates LAN, MAN, CATV technology to provide an pathway metropolitan size has a spanning tree topology. The is multiple drop operates according protocol. protocol based on modified TDM techniques, compensation round trip loop delay, dynamic allocation time slots bus, global synchronization. also permits concatenation data packets reduce overhead. Access bus controlled by allocator operating may allocate bandwidth simultaneously three levels service nodes access namely, isochronous, demand-based dedicated, contention allocation. This method fairness give all sufficient opportunities.
