Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a data real-time communication system based on an IP network.
Background
In the current communication network, the router only forwards the message according to the network address. When the IP data packet is forwarded through the router, if the target network is directly connected with the local router, the data packet is directly delivered to the target host, which is called direct delivery; otherwise, the router looks up the routing information via the routing table and forwards the packet to the indicated next-hop router, which is referred to as indirect delivery.
In indirect delivery, if the router has a route reaching a target network in the routing table, the router transmits the data packet to a next hop router indicated by the routing table; if there is no route but there is a default route in the routing table, passing the datagram to the indicated default router; if neither, the packet is discarded and an error is reported.
