US 7,926,116 B2 · Systems and methods for dynamic decentralized load balancing across multiple sites

Abstract

A method for enabling decentralized dynamic load balancing among a plurality of appliances providing access to a plurality of sites, each site comprising a local area network and at least one server includes: determining, by a first appliance, a first number of services currently available for access via a local area network connected to the first appliance; receiving, by the first appliance from a second appliance, a communication indicating a second number of services currently available for access via a local area network connected to the second appliance; receiving, by the first appliance, a plurality of requests to connect to a service; determining, by the first appliance, a weight to be assigned to the second appliance, wherein the determination is responsive to the second number; and forwarding, by the first appliance to the second appliance, a subset of the plurality of requests, wherein the number of requests comprising the subset is determined in response to the determined weight. Corresponding systems are also described.

(a) determining, by a first appliance, a first number of services executing on one or more servers managed over a first local area network by the first appliance;
(b) receiving, by the first appliance from a second appliance, a communication indicating a second number of services executing on one or more servers managed over a second local area network by the second appliance;
(c) receiving, by the first appliance, a plurality of requests to connect to a service;
(d) determining, by the first appliance, responsive to a ratio between the first number of services executing on the one or more servers on the first local area network managed by the first appliance and the second number of services executing on the one or more servers on the second local area network managed by the second appliance, a weight to be assigned to the second appliance;
and
(e) forwarding, by the first appliance to the second appliance, one or more of the plurality of requests responsive to the weight assigned to the second appliance on the second local area network by the first appliance on the first local area network.

A system for enabling decentralized dynamic load balancing among a plurality of appliances providing access to a plurality of sites, each site comprising a local area network and at least one service, the system comprising:

a first appliance determining a first number of services executing on one or more servers managed over a first local area network by the first appliance, receiving from a second appliance a communication indicating a second number of services executing on one or more servers managed over a second local area network by the second appliance and receiving a plurality of requests to connect to a service,
wherein the first appliance determines a weight to be assigned to the second appliance responsive to a ratio between the first number of services executing on the one or more servers on the first local area network managed by the first appliance and the second number of services executing on the one or more servers on the second local area network managed by the second appliance;
and forwards to the second appliance one or more of the plurality of requests responsive to the weight assigned to the second appliance on the second local area network by the first appliance on the first local area network.
