Infrastructure
For developing high-availability applications, redundancy in the network
infrastructure is the answer. Protection against loss of network segments can be
obtained by implementing a single or coupled ring architecture.
The first level of redundancy can be achieved by implementing a single ring.
ConneXium switches allow the set up of backbone ring configurations.
The ring is constructed using HIPER-Ring ports. If a section of the network becomes
inoperative, the ring structure (including a maximum of 50 switches) converts to a
line-type configuration within 0.5 seconds.
The second level of redundancy can be achieved by implementing a dual ring.
The control intelligence built into the ConneXium switches allows the redundant
coupling of HIPER-Ring ports and network segments.
A third level of redundancy can be achieved by implementing a mesh topology.
The “Spanning Tree” protocol is a protocol that determines a single path for the
information when multiple paths exist. If the active path is broken, the Spanning Tree
protocol enables one of the alternative paths.
ConneXium switches offer this possibility.
