Functional Notes
The differentiated services (DiffServ or DS) model was created in RFC 2474 and RFC 2475 to build on the
original type of service (ToS) field by creating a six-bit sequence (combining the precedence value with the
delay, throughput, and reliability bits). This six-bit sequence increased the number of available values from
8 to 64. The DiffServ model introduced a new concept to quality of service (QoS) in the IP network
environment: per-hop behaviors (PHBs). The PHB premise is that equipment using the DiffServ model
have an agreed upon set of rules (PHB types) for handling certain network traffic. Though the RFC
explicitly defines what each PHB should be capable of, it does not restrict vendor-specific implementation
of the PHBs. Each vendor is free to decide how their network product implements the various defined
PHBs.
