Exinda appliances can use Differentiated Services Code Point (DSCP) markings or other network information to choose where to send traffic. This article provides relevant information on this matter.
If an Exinda appliance is cabled with multiple bridges going to numerous Internet Service Providers (ISPs), it may be preferable to send certain types of traffic over certain bridges, to go to specific destinations. For example, one ISP might be prioritizing one type of traffic over another, so it would be beneficial for that traffic to go through the bridge to that ISP, versus another ISP.
It is possible to use DSCP in an Exinda device for traffic meant to go to specific ISPs. That way, traffic that Exinda marks with the proper DSCP marking can be sorted by the router to properly be sent out the WAN (Wide Area Network) link necessary to facilitate adequate communication. Exinda can mark packets with specific DSCP markings at the policy level. Therefore, a policy which with a particular traffic-type associated with it can have all packets marked.
