Methods and systems for load balancing using forecasting and overbooking techniques |
摘要 |
Methods and systems for establishing user sessions between a client and a server or server farm can be carried out by a load balancing agent executing on a computer in communication with the client, server or server farm. The load balancing agent can intercept a connection request generated by an application executing on a client and responsively select a server on which to establish a user session. Selecting the server can be based on overbooking a particular server and choosing a server with a predetermined amount of forecasted load. Forecasted load can be determined by summing the current load on a server with a current load calculated by multiplying: the average load on the user sessions hosted by the server; by the number of cached user sessions stored on the server; and by the probability that a cached user session reconnects. |

1. A method comprising
(a) receiving, by an agent, a request to establish a session with an application available via a plurality of servers; (b) determining, by the agent, a load for each server of the plurality of servers using a number of cached sessions on each server and a load of a plurality of sessions on each server and a probability that a cached session will reconnect to a server; (c) selecting, by the agent, a server from the plurality of servers using a comparison of the load of each server; and (d) facilitating, by the agent, establishing the session with the application on the selected server. |
