Abstract

Aiming at the problems of high content transmission delay, high packet loss rate and low request hit rate in NDN satellite network, this paper proposed a multi-constraint routing algorithm for satellite network based on SDN and NDN and named SNMcRA(satellite networks multi-constraint routing algorithm). Based on SDN's centralized control and global view, by establishing a multi-constraint routing model, it combined the multi-constraint information of links with ant colony algorithm to solve the least-cost path that met the multi-constraints of delay, bandwidth and packet loss rate, and the nodes dynamically completed the construction of forwarding table FIB(forwarding information base) and pending request table PIT(pending interest table) in the process of packet forwarding. Experimental results show that compared with DSP algorithm, this algorithm reduces the time delay by 35%, improves the bandwidth utilization by 29%, reduces the packet loss rate by 17%, and has significant advantages in the request hit rate.
