The entire process from design (via CAD), to electronic order entry, to iPad-toting installers using electronic blueprints, requires uninterrupted access to the network and server farms in the U.S. and around the world. So, if the network was unavailable, everything stopped.
At EvensonBest’s New York City headquarters, there was running a joke about needing to protect the network guru, Martin Silverman, from being hit by a bus.
The company had a secondary IPSec VPN network, so that if a primary MPLS link failed, the backup link would take over. But that wasn’t good enough. “Routing protocols aren’t as responsive as they need to be,” says Silverman. “If I have two networks and can route over two networks, and the first one goes down, within a minute or two, it will fail over. But if the first network is dropping every third packet or retransmitting a lot of packets, the network may be crawling, but it may not switch over automatically.”
“The four-hour support you get with an MPLS service contract—which is the best you can get—is great except for when your business is actually down for four hours.”
What he needed was automation. “It became necessary to find a solution to allow us to make the network bulletproof to failure and network degradation,” Silverman says.
