Loopback (also written loop-back) is the routing of electronic signals or digital data streams back to their source without intentional processing or modification.It is primarily a means of testing the communications infrastructure.
This layer, presentation Layer and application layer are combined in TCP/IP model. 9P Distributed file system protocol developed originally as part of Plan 9; ADSP AppleTalk Data Stream Protocol; ASP AppleTalk Session Protocol; H.245 Call Control Protocol for Multimedia Communications; iSNS Internet Storage Name Service
Simple Loop Prevention Protocol (SLPP) in computer networking is a data link layer protocol developed by Nortel (previously acquired by Avaya, now a part of Extreme Networks) to protect against Layer 2 network loops. SLPP uses a small hello packet to detect network loops.
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
IEEE 802.1ag is an amendment to the IEEE 802.1Q networking standard which introduces Connectivity Fault Management (CFM). This defines protocols and practices for the operations, administration, and maintenance (OAM) of paths through 802.1 bridges and local area networks (LANs). The final version was approved by the IEEE in 2007. [1]
IS-IS is a link-state routing protocol, operating by reliably flooding link state information throughout a network of routers. Each IS-IS router independently builds a database of the network's topology, aggregating the flooded network information. Like the OSPF protocol, IS-IS uses Dijkstra's algorithm for computing the best path through the ...
In particular, Ethernet operations, administration and maintenance (EOAM) is the protocol for installing, monitoring and troubleshooting Ethernet metropolitan area network (MANs) and Ethernet WANs. The OAM features covered by this protocol are discovery, link monitoring, remote fault detection and remote loopback.
The new layer-2 configuration protocols work with backward-compatible extensions to the Ethernet 802.1 frame format; such minimal changes allow AVB devices to coexist and communicate in standard IT networks, however, only AVB-capable switches and endpoint can reserve network resources with admission control and synchronize local time to a ...
