Preparing servers and clients for DSCP tagging


The only way for a network infrastructure to recognize and prioritize the different data flows is if there is something in the data to identify the type of traffic. This can be done in many ways, some more intelligent than others. However, one sure way to alert the infrastructure is to tag the packets with predefined DSCP marking (which must be agreed upon and honored end-to-end in the network).

Getting ready

This task cannot be completed without proper planning and an agreement with the network team on which values to mark the different data types with. We also need to know which ports the different types of traffic will use. Once this is settled, it's time to configure servers and clients to tag the traffic.

Tip

A good starting point could be these example values: Audio DSCP 46 (EF), Video DSCP 34 (AF41), Signaling 24 (CS3), and file transfer 18.

How to do it...

There are at least three systems that we need to address: clients, domain servers, and...
