| Amit, Network Engineer: “I need to migrate my infrastructure to IP in order to reduce costs. How do I keep my SDH/SONET and TDM applications running reliably?” | | John, Head of Teleprotection: “Absolutely nothing must compromise the operation of our Teleprotection relays. I need deterministic, fail-safe connectivity that meets our latency budget and symmetric delay criteria. “ | | David, Security Engineer: “I need to minimize system vulnerability. Our outside protection is solid but anyone with network access can cause damage. How do I protect from inside threats without increasing network complexity by an order of magnitude?” |
