How to design line optimization and diversion when enterprises have multi-external access?

Many enterprises have applied for multi-WAN access in order to work. Most multi-WAN devices are load balancers directly under the default configuration. Take WSG Internet behavior Management Gateway as an example, the default configuration is as follows:

Operator diversion. Access to telecom websites will give priority to telecommunications lines, while Unicom sites will give priority to Unicom lines.

Load balancing. Load balancing is carried out according to the bandwidth of the wan port.

But in fact, in addition to the default rules, each unit should also create its own line scheme and diversion rules according to its own bandwidth needs. Only in this way can the optimal use of the line be achieved. The following suggestions can generally be considered:

The business mainframe takes the special line. (this ensures the stability of the line and upload bandwidth of the business host)

The finance department should not participate in load balancing and only take a designated line. (Cyber Bank will require re-login when it detects an IP change, so the finance department needs to specify an outside line.)

Office Internet access to enable load balancing. The number of people surfing the Internet in the office is relatively large, so it is suitable for PPPoE dialing. When the number of people is large, multiple PPPoE lines are used to balance the load.

As shown below:

Multi-line equalization belongs to policy routing, for each packet, the shunt rules will be matched one by one, and then there will be no subsequent matching. So if you want to give priority to the implementation of the policy, you need to click the sorted icon to drag.
