Abstract
Managing TCP anycast requests at content delivery network nodes is disclosed. In some embodiments, serving a request includes receiving a request at a node of a plurality of nodes comprising a content delivery network, wherein each of the plurality of nodes share a same anycast IP address to which the request is directed and servicing the request at the node.
Claims12
A method for managing traffic in a content delivery network (CDN), comprising:
- monitoring, with a network device, a number of requests being processed by a plurality of servers in a first node in said CDN;
- receiving a request at the network device in the first node, wherein the request is serviceable by at least one of the first node and a second node;
- first determining, with the network device, whether the first node is in a maintenance or backup mode;
- redirecting, with the network device, the request to a second node if the first node is determined to be in the maintenance or backup mode as decided in the first determining step;
- servicing, with the network device, any existing sessions at the first node if the first node is determined to be in the maintenance or backup mode as decided in the first determining step;
- second determining, with the network device, when the servicing step is finished;
- and
- performing a maintenance operation or backup operation at the first node when it is determined in the second determining step that the servicing step is finished;
- wherein the first node and the second node share a same anycast IP.

A system for managing traffic in a content delivery network (CDN), comprising:
- a network device at a first node of a plurality of nodes in the CDN, said network device configured to:
- monitor a number of requests being processed by a plurality of servers in a first node in said CDN;
- receive a request in the first node, wherein the request is serviceable by at least one of the first node and a second node;
- first determine whether the first node is in a maintenance or backup mode;
- redirect the request to a second node if the first node is determined to be in the maintenance or backup mode as decided in the first determining step;
- service any existing sessions at the first node if the first node is determined to be in the maintenance or backup mode;
- second determine whether the service of any existing sessions at the first node is finished;
- and
- perform a maintenance operation or backup operation at the first node when it is determined that the service of any existing sessions at the first node is finished;
- wherein the first node and the second node share a same anycast IP.
