Its secret sauce has been its relationships with operators.
Buffering packets in a network is both good and bad. It is good because a buffer can hold packets from one stream while another stream’s packets are being processed, to take up and release short bursts of traffic, to hold and then release packets when there is a very short interruption on the wire (or during a route change), and in many other situations. However, queues are bad when there is a standing queue, which means a particular flow always has some number of packets in a particular queue along the path between the source and the destination. This normally occurs at the narrowest point along the path, or rather the link with the lowest bandwidth. In a previous post, I looked at BBR, a change to the way TCP computes its window sizes, that attempts to reduce the amount of traffic “in flight” between a sender and receiver to reduce the number of packets being held in a particular buffer along the way.
This post will consider another solution: CoDel. CoDel is essentially an improved tail drop mechanism that provides the correct signals to TCP to slow down its send rate, or rather to reduce the window size (and Continue reading

When it comes to multi domain or Inter datacenter communication, minimizing the broadcast traffic between the datacenters is an important scaling requirement. Especially if you are dealing with millions of end hosts, localizing the broadcast traffic is critical to save resources on the network and the end hosts. Resources are bandwidth , CPU , memory […]
