DiffServ uses a 6-bit differentiated services code point (DSCP) in the 6-bit differentiated services field (DS field) in the IP header for packet classification purposes. The DS field, together with the ECN field, replaces the outdated IPv4 TOS field.
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.
Differentiated Services Code Point (DSCP): 6 bits Originally defined as the type of service (ToS), this field specifies differentiated services (DiffServ). [34] Real-time data streaming makes use of the DSCP field. An example is Voice over IP (VoIP), which is used for interactive voice services. Explicit Congestion Notification (ECN): 2 bits
Astrologer Tali Edut, one half of ELLE’s resident astrologers The AstroTwins, walks us through the basics, including the signs, planets, houses, and aspects.
QoS Class Identifier (QCI) is a mechanism used in 3GPP Long Term Evolution (LTE) networks to ensure carrier traffic is allocated appropriate Quality of Service (QoS). ). Different carrier traffic requires different QoS and therefore different
As related to network technology, COS is a 3-bit field that is present in an Ethernet frame header when 802.1Q VLAN tagging is present.The field specifies a priority value between 0 and 7, more commonly known as CS0 through CS7, that can be used by quality of service (QoS) disciplines to differentiate and shape/police network traffic.
DSCP may refer to: Differentiated services code point, a field in the IPv4 and IPv6 headers in computer networking; Defense Supply Center Philadelphia, a latter name ...
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
