| Abstract: |
| This paper is proposed the time expenditure of network through a network communication delay model and guarantees the feasibility of real-time communication. An algorithm of the extend CSMA/CD(carrier sense multiple access/collission detection) protocol is also presented to implement the real-time transmission of data or message. |
