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 The DS field, together with the ECN field, replaces the outdated IPv4 TOS field.
A High Assurance Internet Protocol Encryptor (HAIPE) is a Type 1 encryption device that complies with the National Security Agency's HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification).
The Type of Service field in the IP header was originally defined in RFC 791, and has been interpreted for IP Precedence and ToS ever since. The definition was largely derived from a US DoD Specification JANAP-128, which defines message multilevel precedence and preemption.
Explicit Congestion Notification (ECN) is an extension to the Internet Protocol and to the Transmission Control Protocol and is defined in RFC 3168 (2001). ECN allows end-to-end notification of network congestion without dropping packets.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
A virtual router must use 00-00-5E-00-01-XX as its media access control (MAC) address. The last byte of the address (XX) is the virtual router identifier (VRID), which is different for each virtual router in the network.
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.
