BGP
Friday, January 2, 2009 at 8:50AM I always get questions and concerns about loosing connectivity in a datacenter. Just like with power, it takes planning on the part of the client as well as the provider to plan for the day when it fails. Because, sooner or later, it will. Providers will honor their SLAs but to truly prepare for a loss of connectivity will require knowledge of BGP (Border Gateway Protocol) and being multihomed. Simply put, running BGP with two or more providers will allow you to have access to more providers so if one provider looses connectivity the other(s) can pick up the primary providers traffic. However, running BGP and knowledge of routing requires a level of skill and the investment in a router which will also take up room in the cabinet. Bottom line, if your organization requires 100% uptime you will sleep much better at night if you are multihomed.For more information about BGP or for contact information of a skilled engineer that understands BGP, please contact me at woody@globalcoloquote.com or 917-710-5226.
