Abstract
A network switch comprises a load balancer steering mechanism configured to receive a service request received from a load balancer and forward the service request to a first server in a load-balanced server cluster. The service request was initiated by a client and transmitted to the load balancer. The network switch is configured to receive return traffic transmitted by the first server, and to automatically steer the return traffic to the load balancer.
Claims23
A method comprising:
- receiving, at a network switch, a service request forwarded from a load balancer on an overlay network, wherein the service request was initiated by a client;
- forwarding the service request to a first server in a load-balanced server cluster;
- receiving, at the network switch, a server traffic flow transmitted by a server in the load-balanced server cluster;
- and
- automatically steering the server traffic flow to the load balancer on the overlay network.
An apparatus comprising:
- a plurality of network ports;
- a memory;
- and
- a processor configured to:
- receive, a service request forwarded from a load balancer on an overlay network, wherein the service request was initiated by a client;
- forward the service request to a first server in a load-balanced server cluster;
- receive a server traffic flow transmitted by a server in the load-balanced server cluster;
- and
- automatically steer the server traffic flow to the load balancer on the overlay network.
One or more computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:
- receive, at a network switch, a service request forwarded from a load balancer on an overlay network, wherein the service request was initiated by a client;
- forward the service request to a first server in a load-balanced server cluster;
- receiving, at the network switch, a server traffic flow transmitted by a server in the load-balanced server cluster;
- and
- automatically steer the server traffic flow to the load balancer on the overlay network.
