Dual Core Network Design – Dual core design, also known as dual plane or disjoint plane topologies, refers to a highly redundant network chosen by companies whose main objective is to improve the resiliency of their network. Created using different data planes, dual core design is implemented by companies that receive the service from the different service providers. Put simply, big companies use dual core design in order to improve their network. Institutions that generally use this design are found in Europe; they include banks, hospitals, and other financial institutions. What’s more, some companies outside Europe use this design.
The links – passing through same fiber conduit, building, town, or city – are identified as Shared Risk Link Group (SRLG) since they share the same fate if there are any technical glitches. It is pertinent to carefully identify SRLG links between the providers. And if there are shared links, diverge links should be demanded.
