Weighted random early detection (WRED) is a queueing discipline for a network scheduler suited for congestion avoidance. [1] It is an extension to random early detection (RED) where a single queue may have several different sets of queue thresholds.
The QoS technique developed by the working group, also known as class of service (CoS), is a 3-bit field called the Priority Code Point (PCP) within an Ethernet frame header when using VLAN tagged frames as defined by IEEE 802.1Q. It specifies a priority value of between 0 and 7 inclusive that can be used by QoS disciplines to differentiate ...
There is a UK HAIPE variant that implements UKEO algorithms in place of US Suite A. Cassidian has entered the HAIPE market in the UK with its Ectocryp range. Ectocryp Blue is HAIPE version 3.0 compliant and provides a number of the HAIPE extensions as well as support for network quality of service (QoS). Harris has also entered the UK HAIPE ...
Many of the proposed QoS mechanisms that allowed these services to co-exist were both complex and failed to scale to meet the demands of the public Internet. In December 1998, the IETF replaced the TOS and IP precedence fields in the IPv4 header with the DS field , which was later split to refer to only the top 6 bits with the ECN field in the ...
QinQ frames are convenient means of constructing Layer 2 tunnels, or applying quality-of-service (QoS) policies. 802.1ad is upward compatible with 802.1Q. Although 802.1ad is limited to two tags, there is no ceiling on the standard limiting a single frame to more than two tags, allowing for growth in the protocol.
Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network.
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.
This QoS information is called a flowspec and RSVP passes the flowspec from the application to the hosts and routers along the path. Those systems then analyse the flowspec to accept and reserve the resources. A flowspec consists of: Service class; Reservation spec - defines the QoS; Traffic spec - describes the data flow
