Differentiated service

Differentiated Service as defined in RFCs 2474 and 2475 provides an architecture for scalable service differentiation in the Internet. The Differentiated Services (DiffServ) specification defines a code point, which is a 6-bit value that has historically been known as the 8-bit Type of Service (TOS) field in an IP protocol header. Within the DiffServ architecture, setting this code point provides a means of delivering a differentiated or better class of service for these IP packets.

Accelar software provides the capability of setting the DiffServ bits on an IP frame using an IP filter mechanism. The IP DiffServ dialog box allows you to set the decimal values that will be used in an IP protocol filter to set the DiffServ bits


Note: Differentiated Service requires ARU3 hardware (-B modules).
