System and method for mobile network access load balancing. In accordance with a first method embodiment, a method includes receiving, at a network access load balancing controller, performance status information from a mobile network access gateway. The method also includes calculating, at the network access load balancing controller, a dynamic performance score for the mobile network access gateway utilizing the performance status information and calculating, at the network access load balancing controller, a weighted ranking of dynamic performance scores of a plurality of mobile network access gateways. The method further includes assigning, based on the weighted ranking of dynamic performance scores, one of the plurality of mobile network access gateways to serve as a mobile network access gateway for a user element.

System and method for mobile network access load balancing

A method and system for selecting a server load balancer (SLB) for processing requests associated with a client are provided. The method may commence with receiving a Domain Name System (DNS) request from a client DNS server associated with the client. The method may include determining a geolocation of the client. The method may continue with receiving a time delay record including a round trip time (RTT) between the client and each of pluralities of SLBs and a geolocation of each SLB. The method may include matching the geolocation of the client and the geolocation of each of the pluralities of SLBs. The method may include selecting SLBs having the geolocation that matches the geolocation of the client. The method may further include selecting, from the SLBs, an SLB having a lowest RTT and sending a DNS response comprising network data of the selected SLB to the client DNS server.

Distributed global server load balancing controllers sharing service delay time

Provided are methods and systems for managing health statuses of servers. The method for managing health statuses of servers in a distributed GSLB system may include receiving, at a GSLB site controller, health statuses of local servers associated with the GSLB site controller. The method may further include exchanging, by the GSLB site controller, the health statuses of the local servers with health statuses of remote servers associated with at least one remote GSLB site controller. The method may further include distributing, by the GSLB site controller, at least a part of the health statuses of the local servers and the remote servers to SLBs associated with the GSLB site controller.

Managing health status of network devices in a distributed global server load balancing system

A method and system for measuring application response delay is described. The method may commence with receiving a Domain Name System (DNS) request from a client DNS server. The method may include measuring round trip time between the client DNS server and a first Global Server Load Balancing (GSLB) controller, between the first GSLB controller and a server load balancer (SLB) collocated with the first GSLB controller, and between the SLB and an application server. The method may further include receiving measurements of round trip time between the client DNS server and a second GSLB controller, between the second GSLB controller and an SLB collocated with the second GSLB controller, and between the second GSLB controller and a further application server. A cumulative response time associated with the application servers may be calculated based on the measurements to select an application server having a lowest cumulative response time.
