Bandwith Management : Can Do More Than You Can Imagine




Intelligent P2P Traffic Control

Traditional Traffic Control is based on the cache way of packet loss. The UDP protocol itself does not have a mechanism of rate adjustment and P2P transmission mode is particular. Even if you reduced the download data on the LAN port, the network is still occupied by a large number of P2P upload data on WAN port, leading to a waste of bandwidth. That’s why IT administrators often cannot control the P2P traffic at a certain rate.

We found that there is a correlation between the upload rate and download rate for P2P traffic. Sangfor provided a technology that can accurately control the P2P traffic by restraining the upload traffic.

Dynamic Traffic Control

Sangfor IAM Intelligent P2P Traffic Control

Traditional bandwidth management policies can’t be adjusted automatically, which leads to a waste of bandwidth. For example, you set up a policy to limit YouTube (P2P) video traffic to a maximum 1 MB/s per user. If a part of your staff are going on business trip, then the business bandwidth guarantee channel is idle. The bandwidth usage of the line is lower than before.

We call it idle status, under the traditional way of static bandwidth control. Idle bandwidth won’t be used, which leads to the waste of bandwidth. However Sangfor IAM can provide the technology for dynamic bandwidth control, which allow the idle bandwidth to be occupied by limited channel to improve user experience and bandwidth utilization.
