A method of traffic flow scheduling in Edge machine room based on network traffic statistics and feedback

streaming server deployment structure brings up the following issues:1 due to the high cost of the core network, the traffic expense of the source media server is higher;2 Intermediate multistage Streaming Media server increases the end-to-end delay, Reduced user experience;3 backbone network core room is stable, but the distribution of the national media Stream

Some domain knowledge of DDoS attack--(traffic model for stable service is more effective) unstable service uses the traffic cost detection algorithm, when the attack occurs, the proportion of each protocol in the network has changed obviously.

In the past, many firewalls detected DDoS attacks based on a pre-set traffic threshold, exceeding a certain threshold, and generating an alarm event.The finer ones may set different alarm curves for different flow characteristics ., so that when an attack occurs suddenly, such as a SYN Flood, the SYN message in the network will exceed the threshold, indicating that a SYN flood attack has occurred.But when t

in which I point all flows ) –sum ( the Nether Stream where I point all flows out )Assuming that the mi is greater than 0and that the point must also flow out of the free stream to mi , then we connect a single mi edge from the source point to that point. Assuming that Mi is less than 0, this point must also flow in The free stream of MI. So we'll go from that point to the edge of a Mi to the meeting point. Suppose the maximum flow of the s->t is calculated to see if the full stream ( The n
