Applications are king. Forget all the things you do to ensure proper routing in your data center. Forget the tweaks for OSPF sub-second failover or BGP optimal path selection. None of it matters to your users. If their login to Seibel or Salesforce or Netflix is slow today, you’ve failed. They are very vocal when it comes to telling you how much the network sucks today. How do we fix this?
The first problem is the cloud focus of applications. Once our packets leave our border routers it’s a giant game of chance as to how things are going to work next. The routing protocol games that govern the Internet are tried and true and straight out of RFC 1771(Yes, RFC 4271 supersedes it). BGP is a great tool with general purpose abilities. It’s becoming the choice for web scale applications like LinkedIn and Facebook. But it’s problematic for Internet routing. It scales well but doesn’t have the ability to make rapid decisions.
The stability of BGP is also the reason why it doesn’t react well to changes. In the old days, links could go up and down quickly. BGP was designed to avoid issues with Continue reading
