Differentiated Services, or DS. A protocol for specifying and controlling network traffic by class so that certain types of traffic get precedence - for example, voice traffic, which requires a relatively uninterrupted flow of data, might get precedence over other kinds of traffic.
Differentiated services. An architecture for providing different types or levels of service for network traffic. Diffserv aggregates flows in the network so that routers and switches need to distinguish only a relatively small number of aggregated flows, even if those flows contain thousands or millions of individual flows.
Differentiated Services An IETF standard that redefines the TOS bit s in the IP header in order to assign a priority of service to that packet.
A protocol for classifying network traffic and prioritizing traffic by its type. VoIP traffic can be allotted a higher priority than regular data, helping to reduce latency and jitter and preserve voice quality even when the network is under heavy load. Back

DiffServ (Differentiated Services) is a quality of service protocol that prioritizes IP voice and data traffic to help preserve voice quality even when network traffic is heavy.
Differentiated Services A IETF standard for a small, well-defined set of per-packet building blocks from which a variety of services may be built, thereby providing a framework for delivering quality of service (QoS) in networks. .This effort is largely focused on the use of the ToS field in IPv4 header as a QoS signaling mechanism, and it aims to provide definitions appropriate for aggregated flows for any level of aggregation. At least two services have initially been defined under this effort: The "Assured Service" and the "Preferred Service," each with slightly different definitions of service that from a technical perspective might be called "engineered best effort." RFC 2474 defines how to assign a class of service by setting the ToS field.
An architecture based on a simple model where traffic entering a network is classified and possibly conditioned at the boundaries of the network. The class of traffic is then identified with a DS code point or bit marking in the IP header. Within the core of the network, packets are forwarded according to the per-hop behavior associated with the DS code point.
Differentiated Services; the name of the field in the IP Datagram that specifies the service level (forwarding priority) for this packet.
Differentiated Services (based on RFC 2474). DiffServ uses the type-of-service (ToS) byte to identify different packet flows on a packet-by-packet basis. DiffServ adds a Class Selector code point (CSCP) and a Differentiated Services code point (DSCP).
An approach to providing QoS in networks that use a small, well-defined set of building blocks from which a variety of services can be built. DiffServ evolved from IETF's IntServ. It is a prioritization model, with preferential allocation of resources based on traffic classification.
