0 to 2 bits are Precedence fields representing the 8 priorities of message transmission
ranging from 7 to 0 from high to low, with either Level 7 or 6 as the highest priority that
is generally reserved for routing or updating network control communication. User-level
applications only have access to Level 0 to 5.
ToS domain, in addition to Precedence fields, also includes D, T and R bits: D-bit
represents the Delay requirement (0 for normal delay and 1 for low delay). T-bit
represents the throughput (0 for normal throughput and 1 for high throughput). R-bit
represents the reliability (0 for normal reliability and 1 for high reliability). ToS domain
reserves the 6 and 7 bits.
RFC1349 redefines the ToS domain by adding a C-bit to represent the Monetary
Cost. The IETF DiffServ group then redefines the 0 to 5 bits of ToS domain in the IPv4
message header of RFC2474 as DSCP and renames it as DS (Differentiated Service) byte
as shown in the figure above.
The first 6 bits (0-5 bits) of DS field distinguish the DSCP (DS Code Point), and the
higher 2 bits (6-7 bits) are reserved. The lower 3 bits (0-2 bits) are CSCP (Class Selector
Code Point), with the same CSCP value representing the DSCP of the same class. DS
nodes select corresponding PHB (Per-Hop Behavior) according to DSCP values.
17.1 General
17.1.1 Property
Network congestion resulting from the competition for resource use rights among
messages at the same time is usually solved by queue scheduling, thus avoiding
intermittent congestions. Queue scheduling technologies include SP (Strict-Priority),
WFQ (Weighted Fair Queue), WRR (Weighted Round Robin), and DRR (Deficit Round
Robin, which is also expanded from RR technology).
