In this article we will discuss RPR, will make brief discussion on RPR, last article we discuss about WiFi.
Resilient Packet Ring, also known as IEEE 802.17, is a protocol standard designed for the optimized transport of data traffic over optical fiber ring networks. The standard began development in November 2000 and has undergone several amendments since its initial standard was completed in June 2004.
Resilient Packet Ring (RPR) operates in the Media Access Control (MAC) layer of the Open Systems Interconnection (OSI) model. It provides a packet based transmission facility, with the aim of improving efficiency of Ethernet and IP services. RPR provides improved bandwidth utilization and throughput, greater speed of deployment, and optimized equipment and operational costs.
The control signal is carried in the opposite direction of the data traffic whose information it carries. For example if the outer ring carries data, its control information is carried by the inner ring.
An RPR node can dynamically negotiate bandwidth issues with other nodes. It is a Quality of Service (QoS) aware facility that can schedule traffic in order of their priorities. This avoids congestion and minimizes failed transmissions. If a link is broken in any ringlet, then data transmission continues through methods of steering and wrapping. In steering, all nodes are notified of the broken link and they reroute their traffic. In wrapping, the data traffic is looped back at the last node before the link breakage and routed to the destination station via the other ringlet.
I am Hamza arif, and i am excited to learn new things, i am well focused for my work and always try to explore new things. My graduate is in BS (Telecom) and i am expert in Networks and working on new technology is my passion i work a lot on AI (Artificial Intelligence) Augmented Reality and many other projects.
