A Bi-directional Resource Reservation Proposal for Hard Congestion

For real-time multimedia communication has strict QoS (Quality of Service) requirements for network, especially it is very sensitive to packet loss rate and delay jitter. When the communication network becomes seriously congested, a Bi-directional Resource Reservation model solution is proposed. This scheme supports the QoS priority and Bi-directional Reservation. The results show that the internal node maintenance in the scheme of Bi-directional Resource Reservation model is based on distinguishing the reserve service level, which has good expansibility and flexibility.
