Abstract
The present application describes a system and method for determining a latency between a client device and various servers of a networking system.
Claims15
A method, comprising:
- receiving, at a first server, a first request from a client device;
- determining that a latency measurement instruction has been issued;
- based on determining that the latency measurement instruction has been issued and in response to receiving the first request from the client device, providing a first redirect response to the client device, the first redirect response causing the client device to submit a second request to a second server;
- receiving, at the first server, a final request, the final request being provided to the first server from the client device based on the client device receiving a second redirect response from the second server;
- determining a latency measurement between the client device and the second server based, at least in part, on a time between when the first redirect response is provided to the client device and when the final request is received by the first server;
- determining whether the latency measurement is above a latency threshold;
- and
- in response to determining that the latency measurement is above the latency threshold, causing the client device to access the second server instead of the first server.

A system, comprising:
- a processor;
- and
- a memory coupled to the processor and storing instructions that, when executed by the processor, perform operations, comprising:
- receiving a first request from a client device;
- receiving a latency measurement instruction;
- based on receiving the latency measurement instruction and in response to receiving the first request from the client device, providing a first redirect response to the client device, the first redirect response causing the client device to submit a second request to a server;
- receiving a final request, the final request being provided from the client device based on the client device receiving a second redirect response from the server;
- determining a latency measurement between the client device and the server based, at least in part, on a time between when the first redirect response is provided to the client device and when the final request is received;
- determining whether the latency measurement is above a latency threshold;
- and
- in response to determining that the latency measurement is above the latency threshold, causing the client device to access the server.

A method, comprising:
- providing a latency measurement instruction to a first server, the latency measurement instruction causing:
- the first server to receive a first request from a client device;
- the first server to provide a first redirect response to the client device, the first redirect response causing the client device to submit a second request to a second server;
- the first server to receive a final request, the final request being provided from the client device based on the client device receiving a second redirect response from the second server;
- the first server determining a latency measurement between the client device and the first server based, at least in part, on a time associated with the first redirect response and the final request;
- and
- the first server determining whether the latency measurement is above a latency threshold;
- and
- receiving an instruction from the first server causing the client device to access the second server instead of the first server in response to the first server determining that the latency measurement is above the latency threshold.
