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 The DS field, together with the ECN field, replaces the outdated IPv4 TOS field.
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
The label edge routers at the edges of an MPLS cloud map between the end-to-end identifier, such as an IP address, and a link-local label. At each MPLS hop, there is a forwarding table that tells the label-switched router which outgoing interface is to receive the MPLS packet, and what label to use when sending the packet out that interface.
Broadly, there are four types of tools that help create network maps and diagrams: Hybrid tools; Network Mapping tools; Network Monitoring tools; Drawing tools; Network mapping and drawing software support IT systems managers to understand the hardware and software services on a network and how they are interconnected. Network maps and diagrams ...
To reflect multi-vendor driver support, and to prevent potential quarrels with APC, the project name was changed to Network UPS Tools starting from 0.42.0, released October 31, 1999. Arnaud Quette led the project since 2005, increasing its visibility to prospective contributors by creating a project on the Debian Alioth Forge , making it less ...
This allows intermediate routers that support ECN to mark those IP packets with the CE code point instead of dropping them in order to signal impending congestion. Upon receiving an IP packet with the Congestion Experienced code point, the TCP receiver echoes back this congestion indication using the ECE flag in the TCP header.
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.
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
