Smart Link
Smart Link is a feature developed to address the slow
convergence issue with STP. It provides link redundancy as well
as fast convergence in a dual uplink network, allowing the backup
link to take over quickly when the primary link fails.

MSTP
As a Layer 2 management protocol, the Multiple Spanning Tree
Protocol (MSTP) eliminates Layer 2 loops by selectively blocking
redundant links in a network, and in the mean time, allows for link
redundancy.

RRPP
The Rapid Ring Protection Protocol (RRPP) is a link layer
protocol designed for Ethernet rings. RRPP can prevent
broadcast storms caused by data loops when an Ethernet ring is
healthy, and rapidly restore the communication paths between
the nodes in the event that a link is disconnected on the ring.

A single high availability technology cannot solve all availability problems in more and more complex
network environments. Therefore, various availability technologies are required to enhance network
availability on a basis of detailed analysis of network environments and user requirements. For
example, at the distribution layer, a redundancy mechanism should be adopted on edge nodes to
connect them to the corresponding nodes, and at the core layer, nodes should be meshed.
Therefore, to achieve complete high availability, network designers and managers need to take into
full consideration during the design, construction, and maintenance of a network.
