Transfer Delays in a SIMA Netowrk

摘要

Differentiated Services approach has been proposed for providign Quality of Service in Internet. Simple Integrated Media Access (SIMA) is a network service condcept that uses this approach by utilising priority bits in packet headers. ~2 Three drop preference bits are used for making the decision about packets to be discarded when congestion arises in a core network node. A single delay indication bit marks the packet either as belonging to a real time or non real time flow. The acceptance of packets is not directly connected with real time properties of a packet.
