Individualized connectivity based request handling
Individualized connectivity based request handling is disclosed. For example, a content source is accessed by a client device and a load balancer executes on a processor to receive a first request based on the client device accessing the content source. A first session variable is set to a first value in a first session and a first latency to the client device is measured. A first plurality of target nodes is selected based on the first session variable. A first plurality of messages is sent to the first plurality of target nodes. A second request is received from the client device after the first session expires, starting a second session. The first session variable is set to a different second value in the second session. A second plurality of messages is sent to a second plurality of target nodes different from the first plurality of target nodes.
1. A system comprising:
a content source accessed by a client device over a network; and
a load balancer service across the network from the client device executing on one or more processors to:
receive a first request based on the client device accessing the content source;
establish a first session between the client device and the load balancer service;
set a first session variable to a first value in the first session;
send a first plurality of messages to a first plurality of target nodes selected based on the first value of the first session variable;
update the first value to a second value responsive to receiving a result of a probe sent by one of the load balancer service and the client device, wherein the result of the probe is stored by at least one of the load balancer service and the client device as a client device variable;
receive a second request in the first session from the client device;
send a second plurality of messages to a second plurality of target nodes different from the first plurality of target nodes based on the second value of the first session variable;
establish a second session between the load balancer service and the client device after the first session is terminated; and
in the second session, setting a first session variable of the second session to a third value based on the client device variable stored from the first session.
2. The system of claim 1 , wherein the first session variable is one of a timeout value, a request class, a client device type, and a network connection type.
3. The system of claim 1 , wherein a first latency between the load balancer service and the client device is computed from an elapsed time between at least one of (i) the client device accessing the content source and the load balancer service receiving the first request, (ii) the content source responding to the client device and the load balancer service receiving the first request, and (iii) the client device sending the first request and the load balancer service receiving the first request.
4. The system of claim 1 , wherein the first plurality of target nodes is selected based on a respective average response time from each of the first plurality of target nodes.
5. The system of claim 1 , wherein the probe measures at least one of a round trip latency between the load balancer service and the client device and a network bandwidth of the client device.
6. The system of claim 1 , wherein the probe is triggered based on one of (i) the client device accessing one of the content source and the load balancer service and (ii) a timing discrepancy between the load balancer service and the client device.
7. The system of claim 1 , wherein the client device variable is one of a measured latency between the load balancer service and the client device, a network bandwidth of the client device, a screen resolution of the client device, a user account logged into the client device, and a measurable physical attribute of the client device.
8. The system of claim 1 , wherein the first plurality of target nodes is a plurality of advertisers, the load balancer service conducts a first auction with the first plurality of target nodes for a first advertisement impression associated with a first view of the content source accessed by the client device.
9. The system of claim 8 , wherein an advertisement type is selected based on a client device variable, an advertisement auction setting is adjusted based on a client device variable, and the advertisement auction setting includes at least one of an auction timeout setting and an auction target setting.
10. A method comprising:
receiving a first request based on a client device accessing a content source over a network;
establishing a first session between the client device and a load balancer service over the network;
setting a first session variable to a first value in the first session;
sending a first plurality of messages to a first plurality of target nodes selected based on the first value of the first session variable;
updating the first value to a second value responsive to receiving a result of a probe sent by one of the load balancer service and the client device, wherein the result of the probe is stored by at least one of the load balancer service and the client device as a client device variable;
receiving a second request in the first session from the client device; and
sending a second plurality of messages to a second plurality of target nodes different from the first plurality of target nodes based on the second value of the first session variable;
establishing a second session between the load balancer service and the client device after the first session is terminated; and
in the second session, setting a first session variable of the second session to a third value based on the client device variable stored from the first session.
11. The method of claim 10 , wherein the first session variable is one of a timeout value, a request class, a client device type, and a network connection type.
12. The method of claim 10 , further comprising:
computing a first latency between the load balancer service and the client device from an elapsed time between at least one of (i) the client device accessing the content source and the load balancer service receiving the first request, (ii) the content source responding to the client device and the load balancer service receiving the first request, and (iii) the client device sending the first request and the load balancer service receiving the first request.
13. The method of claim 10 , further comprising:
selecting the first plurality of target nodes based on a respective average response time from each of the first plurality of target nodes.
14. The method of claim 10 , wherein a second session variable includes at least one of a motion setting, an orientation setting, and a network bandwidth setting.
15. The method of claim 10 , further comprising:
measuring, by the probe, a round trip latency between the load balancer service and the client device.
16. The method of claim 10 , further comprising:

19. The method of claim 10 , wherein the client device variable is one of a measured latency between the load balancer service and the client device, a network bandwidth of the client device, a screen resolution of the client device, a user account logged into the client device, and a measurable physical attribute of the client device.
20. The method of claim 10 , further comprising:
storing the client device variable in a cookie.
