Achieving network redundancy is one of the most important strategies for meeting those commitments, and Netnod services are specifically designed with redundancy in mind. The design of Netnod’s connection model in Stockholm, in particular, is a leading example offering many advantages for operators who require highly redundant interconnection services. What is network redundancy? network topology and help networks IXPs in other cities are all by dark Redundancy is the ability of a network route packets around link and router fibre, arranged with one of the local to withstand a failure without failures.
