what is the difference between the RRPP/SEP/STP/ERPS?

In the current networking, various loop protocols emerge in an endless stream. How should we choose? For the Huawei switch, it support the ERPS/SEP/STP/RRPP.

what is the difference between these loop protocols?


RRPP

Provides fast convergence and carrier-class reliability.

  • Supports only level-1 sub-ring in ring networking.

  • Is a Huawei proprietary protocol that cannot be used for communication between Huawei and non-Huawei devices.

STP/RSTP/MSTP

  • Applies to all Layer 2 networks.

  • Is a standard IEEE protocol that allows Huawei devices to communicate with non-Huawei devices.

Provides low convergence on a large network, which cannot meet the carrier-class reliability requirement.

SEP

  • Applies to all Layer 2 networks.

  • Provides fast convergence and carrier-class reliability.

  • Displays the topology of an entire ring, facilitating fault location and device maintenance.

Is a Huawei proprietary protocol that cannot be used for communication between Huawei and non-Huawei devices.

ERPS

  • Provides fast convergence and carrier-class reliability.

  • Is a standard ITU-T protocol that allows Huawei devices to communicate with non-Huawei devices.

  • Supports single-ring and multi-ring topologies in ERPSv2.

Requires the network topology to be planned in advance. The configuration is complex.

the RRPP and SEP is the private protocol in Huawei, for the SEP we can use it on the safe city network.

the STP can communicate with other non-huawei device, but it convergence is slowly

the ERPS provide fast convergence, but if there have intersecting rings, it only support one down point.

Clearly explains the differences between these protocol families.

Small network stack may be a good choice.
