How does DSCP marking work?
Once a packet is identified, it is typically marked near the source of the traffic flow, allowing the packets to receive differentiated treatment. Marking is typically done at the Layer 3 IP header using the Differentiated Services Code Point (DSCP); LAN implementations use the Class of Service (COS) field.
How many DSCP values are there?
64 different values
DSCP Value. DiffServ Code Point (DSCP) uses the 6 bits, thereby giving 2^6 = 64 different values (0 to 63).
How is DSCP value set?
Go to Computer configuration > Windows Settings > Policy-based QoS and right click on “Create new policy”. Check “Specify DSCP Value” and use the desired value (for example, 8). Click “Next”. Check “Only application with this executable name:” and fill with Process Name (executable).
What is DSCP bit?
DiffServ uses a 6-bit differentiated services code point (DSCP) in the 8-bit differentiated services field (DS field) in the IP header for packet classification purposes. The DS field replaces the outdated IPv4 TOS field.
What is DSCP protocol?
Differentiated Services Code Point (DSCP) is a means of classifying and managing network traffic and of providing quality of service (QoS) in modern Layer 3 IP networks. It uses the 6-bit Differentiated Services (DS) field in the IP header for the purpose of packet classification.
What is DSCP value QoS?
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.

How is DSCP marking used in the network?
A DSCP marking is used to mark packets as they go out of your network. The mpls provider will, usually, do something with a certain marking. For example, if you mark all http traffic as dscp 21, the ISP (mpls provider) will guarantee a rate for any packet with dscp 21 as a marking. This is where it’s important.
When to use differentiated services code point ( DSCP )?
Differentiated Services Code Point (DSCP) The definition of ToS was changed entirely in RFC 2474, and it is now called Differentiated Service (DS). On the eight fields, the upper six bit contain value called Differentiated Services Code Point (DSCP). The last two bits are used for Explicit Congestion Notification and it is defined in RFC 3168.
How is DSCP marking used in sonicos traffic management?
DSCP marking can be performed on traffic to/from any interface and to/from any zone type, without exception. DSCP marking is controlled by Access Rules, from the QoS tab, and can be used in conjunction with 802.1p marking, as well as with SonicOS’S internal bandwidth management.

What happens if you mark all HTTP traffic as DSCP 21?
For example, if you mark all http traffic as dscp 21, the ISP (mpls provider) will guarantee a rate for any packet with dscp 21 as a marking. This is where it’s important. Generally, the ISP will remark everything to default (dscp 0) if you don’t pay them for qos as a service.
