DiffServ

DiffServ PHB (Per Hop Behavior) values

Parameter

pertain to a differential prioritizing

fields

system for IP packets as handled by

 

DiffServ-compatible routers. There are 64

 

values, each with an elaborate technical

 

description. These descriptions are found in

 

TCP/IP standards RFC2474, RFC2597, and,

 

for present purposes, in RFC3246, which

 

describes the value 34 (34 decimal; 22 hex) for

 

Assured Forwarding behavior (default for

 

Call Control PHB) and the value 46 (46

 

decimal; 2E hexadecimal) for Expedited

 

Forwarding behavior (default for Voip Media

 

PHB). Before using values other than these

 

default values of 34 and 46, consult these

 

standards documents and/or a qualified IP

 

telecommunications engineer.

 

To disable DiffServ, configure both fields to 0

 

decimal.

 

 

The next page explains DiffServ in the

 

context of the IP datagram.
