Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism ... RFC 3290 — An informal management model for ...
In this model, applications use the Resource Reservation Protocol (RSVP) to request and reserve resources through a network. Differentiated services ("DiffServ") implements the prioritized model. DiffServ marks packets according to the type of service they desire.
Differentiated service is extensively covered in a few narrow technical areas, such as telecoms networks and internet (see Differentiated services).It is also mentioned in some marketing sources, with reference to customer segmentation.
In computer networking, integrated services or IntServ is an architecture that specifies the elements to guarantee quality of service (QoS) on networks. IntServ can for example be used to allow video and sound to reach the receiver without interruption.
In RFC 2474 the definition of this entire field was changed. It is now called the "DS" (Differentiated Services, "DiffServ") field and the upper 6 bits contain a value called the "DSCP" (Differentiated Services Code Point). The upper 3 bits of DS maintains compatibility with IP Precedence.
RFC 2638 from the IETF defines the entity of the Bandwidth Broker (BB) in the framework of differentiated services (DiffServ). According to RFC 2638, a Bandwidth Broker is an agent that has some knowledge of an organization's priorities and policies and allocates quality of service (QoS) resources with respect to those policies.
DeepSeek rattled the global AI industry last month when it released its open-source R1 reasoning model, which rivaled Western systems in performance while being developed at a lower cost.
In the CP, DCF is used. In the CFP, the AP sends Contention-Free-Poll (CF-Poll) packets to each station, one at a time, to give them the right to send a packet. The AP is the coordinator. Although this allows for a better management of QoS, PCF does not define classes of traffic as is common with other QoS systems (e.g. 802.1p and DiffServ).
