17 Ring protocols Drawbacks of STP The convergence time is too long! STP (spanning-tree protocol) is built for the redundant links and loop avoidance network. When topology changes, STP takes about seconds to converge. RSTP (Rapid STP) improves the speed of convergence for bridged network from seconds to about 4 seconds, by immediately transitioning root and designated ports to the forwarding state. Ring Protocols only spends ms converging but it uses a ring topology instead of tree topology. STP RSTP Ring Proto Topology Type Any Topology Any Topology Ring Topology Convergence Time seconds 6 seconds ms* 16

18 ntroduction to ERPS ERPS is a protocol defined by the TU-T to prevent loops at Layer 2. Because it is defined in Recommendation TU-T G.8032/Y.1344, it is also called G ERPS defines R-APS PDUs and the protection switching mechanism. ERPS blocks a specified port to prevent loops at the Ethernet link layer. ERPS has two versions: ERPSv1 released in June 2008 and ERPSv2 released in August Ring etwork Protocol Advantage Disadvantage STP/RSTP/MSTP RRPP SEP ERPS Apply to all Layer 2 networks. Are standard EEE protocols that allow Huawei devices to communicate with non-huawei devices. Features fast convergence, meeting the carrier-class reliability requirement. Applies to all Layer 2 networks. Features fast convergence, meeting the carrier-class reliability requirement. Displays the topology of an entire ring, facilitating fault location and device maintenance. Features fast convergence, meeting the carrier-class reliability requirement. Provides a low convergence speed on a large network, which cannot meet the carrier-class reliability requirement. Supports only level-1 subrings on ring networks. s a Huawei proprietary protocol that does not support interoperability between Huawei and non-huawei devices. s a Huawei proprietary protocol that does not support interoperability between Huawei and non-huawei devices. Supports single-ring and multi-ring networking. On a ring network, devices supporting ERPS can communicate with each other regardless of their manufacturers. 17 Page 17
