Abstract

The techniques and systems described herein implement an improved peer matching service by coordinating peer matching requests across multiple peer matching nodes configured within a peer matching unit so that resource consumption can be spread out and resource limitations are not exceeded. Moreover, the peer matching service can determine if a peer matching unit is overloaded (e.g., experiencing an increased number of requests in a given time interval that is causing performance degradation), and the peer matching service can implement an action to scale out the number of requests within the peer matching unit (e.g., re-distribute some peer matching requests to another peer matching unit). In various examples, the peer matching service can determine if peer devices are co-located peer devices based on location information and can generate a list that prioritizes the co-located peer devices.

Claims17

Dependent claims

A system comprising:

one or more processors;
and
memory storing instructions that, when executed by the one or more processors, configure the one or more processors to:
receive, from a particular peer matching node of a plurality of peer matching nodes that register peer identifiers for peer matching services associated with a content identifier, first information representative of a first set of changes to a first list of peer identifiers maintained by the particular peer matching node, wherein a peer match enables a peer user device to download content associated with the content identifier from another peer user device via a peer-to-peer connection rather than from a content delivery network;
update, based at least in part on the first information, a second list of peer identifiers associated with a plurality of peer user devices that have registered for peer matching services associated with the content identifier across the plurality of peer matching nodes;
generate second information representative of a second set of changes to the second list of peer identifiers, the second set of changes occurring at one or more of the plurality of peer matching nodes other than the particular peer matching node;
associate a version number with the second information;
receive a request for the version number from the particular peer matching node, the particular peer matching node being previously unavailable to receive the second information;
and
in response to receiving the request for the version number from the particular peer matching node, send, to the particular peer matching node, the second information.

A method comprising:

receiving, from a particular peer matching node of a plurality of peer matching nodes that register peer identifiers for peer matching services associated with a content identifier, first information representative of a first set of changes to a first list of peer identifiers maintained by the particular peer matching node, wherein a peer match enables a peer user device to download content associated with the content identifier from another peer user device via a peer-to-peer connection rather than from a content delivery network;
updating, based at least in part on the first information, a second list of peer identifiers associated with a plurality of peer user devices that have registered for peer matching services associated with the content identifier across the plurality of peer matching nodes;
generating, by one or more processors, second information representative of a second set of changes to the second list of peer identifiers, the second set of changes occurring at one or more of the plurality of peer matching nodes other than the particular peer matching node;
associating a version number with the second information;
receiving a request for the version number from the particular peer matching node, the particular peer matching node being previously unavailable to receive the second information;
and
in response to receiving the request for the version number from the particular peer matching node, sending, to the particular peer matching node, the second information.

One or more computer storage media comprising instructions that, when executed by one or more processors, configure a device to perform operations comprising:

receiving, from a particular peer matching node of a plurality of peer matching nodes that register peer identifiers for peer matching services associated with a content identifier, first information representative of a first set of changes to a first list of peer identifiers maintained by the particular peer matching node, wherein a peer match enables a peer user device to download content associated with the content identifier from another peer user device via a peer-to-peer connection rather than from a content delivery network;
updating, based at least in part on the first information, a second list of peer identifiers associated with a plurality of peer user devices that have registered for peer matching services associated with the content identifier across the plurality of peer matching nodes;
generating second information representative of a second set of changes to the second list of peer identifiers, the second set of changes occurring at one or more of the plurality of peer matching nodes other than the particular peer matching node;
associating a version number with the second information;
receiving a request for the version number from the particular peer matching node, the particular peer matching node being previously unavailable to receive the second information;
and
in response to receiving the request for the version number from the particular peer matching node, sending, to the particular peer matching node, the second information.
