Table 6-1 lists the commonly used DSCP values described in RFC 2475. Table 6-2 lists the RFC 791 precedence values from least to most important. Flash - mainly used for Voice Signaling or for Video. Critical -mainly used for Voice RTP.

Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks.

In networking, DSCP, TOS, CoS, and Precedence are terms related to Quality of Service (QoS) which is used to prioritize certain types of traffic to ensure the performance of critical applications over a network. Don’t mix up TOS (Type of Service) and COS (Class of Service).

Sep 5, 2024 · This document describes how to set the Differentiated Services Code Point (DSCP) values in Quality of Service (QoS) configurations on a Cisco router.

Feb 1, 2024 · Differentiated Service Code Points (DSCP) is an aspect of QoS (Quality of Service) used to classify and manage network traffic. The DSCP field is 6 bits in length and can take on values from 0 to 63. DSCP is often described as “managed unfairness,” and with good reason.

Policy matches are based on Differentiated Services Code Point (DSCP) values, which network devices use to identify traffic to be handled with higher or lower priority.

Mar 13, 2017 · For example, packets with a DSCP value of `110000' (IP-precedence 110) have a preferential forwarding treatment (scheduling, queuing, etc.) as compared to packets with a DSCP value of `100000' (IP-precedence 100).

Nov 15, 2024 · The Differentiated Services (Diffserv) architecture specifies use of the DS field in the IPv4 and IPv6 packet headers to carry one of 64 distict differentiated services field codepoint (DSCP) values.

This lesson explains IP Precedence, DSCP (Differentiated Services), codepoints, TOS byte, DS field, CS,AF and EF.

Sep 13, 2024 · Primarily used in network traffic engineering, DSCP assigns values to data packets that dictate their priority through the network. This guide offers a detailed look at the Cisco DSCP value chart, decoding its complexities and providing insights into how different values impact data flow.
