What is the best DSCP mark?

Most games use udp high ports, icmp is just for ACC ping to work better. udp ports and icmp are marked 48(CS6), this marking worked best for me. You can also try 56 (CS7), 46 (EF) or 40 (CS5). Change to the udp ports your games use.

What are DSCP values?

A Differentiated Services Code Point (DSCP) is a packet header value that can be used to request (for example) high priority or best effort delivery for traffic.

What is the best DSCP value?

Use DSCP values of 25 for control traffic. Latency-sensitive traffic Traffic, such as VoIP, that must be delivered as quickly as possible. Typically, you should assign this a DSCP value of 46, known as Expedited Forwarding (EF).

How does DSCP marking work?

The DSCP is defined in RFC 2474 and 2475. It is a method that classifies the way an IP packet is queued while waiting to be forwarded within a router. Using DSCP, a system (or router) can assign Assured forwarding (AF) codepoints, using one of four AF classes and one of three drop precedence values.

Is it good or bad to use DSCP marking?

This can be good and bad. A good scenario is to make sure that torrent clients aren’t getting priority (while ideally your enterprise network qos policies should overcome this problem as well) A bad scenario is overriding DSCP markings from Jabber Client which marks packets genuinely for seperating audio and video streams treatment.

What should be the default value for DSCP?

Use a DSCP value of 34. Best-effort (BE) traffic Standard traffic, including any traffic not marked with a DSCP number, that should be handled after either of the preceding two queues. This traffic should have a DSCP value of 0, which is the default if no DSCP value is specified.

What’s the difference between throttling and DSCP marking?

By using throttling, a QoS policy limits the outgoing network traffic to a specified throttle rate. Both DSCP marking and throttling can be used together to manage traffic effectively. By default, the Specify Throttle Rate check box is not selected.

Why are DSCP values lost when packets leave the network?

DSCP values might be lost when packets leave your network because most organizations do not trust priorities provided by computers outside the organization. Because sending traffic labeled as high priority can create a denial-of-service (DoS) attack, DSCP values from untrusted computers might be malicious.
