Abstract

Systems and methods are described for facilitating delivery of resources via peer-to-peer connections without requiring an intermediary signaling server. Typically, before establishing a peer-to-peer connection, peers must exchange signaling information such as their reachability over a network. Traditional systems often rely on an intermediary signaling server to act as a go-between for peers and assist in the exchange of signaling information. The present disclosure removes the need for a signaling server. Instead, peers may utilize message collections on a messaging system to exchange signaling information. A requesting peer may submit a request to access a resource to a message collection for that resource. A providing peer may obtain the request, and submit a response to a message collection for the requesting peer. Peers may continue to exchange information via the collections until a peer-to-peer connection is established.

Dependent claims

A system to facilitate establishment of a peer-to-peer connection between peers to provide video content, without requiring an intermediary signaling server to conduct signaling between the peers, the system comprising:

a messaging system comprising one or more processors and configured to provide:
a resource queue associated with the video content and configured to contain signaling messages from a first peer and to make the signaling messages from the first peer available for retrieval by a second peer providing access to the video content;
and
a peer queue associated with the first peer and configured to contain signaling responses from the second peer and to make the signaling responses from the second peer available for retrieval by the first peer,
wherein the first peer, the second peer, and the messaging system each represent distinct computing devices in communication over a network;
and
a streaming video system comprising one or more processors and configured to implement the second peer providing access to the video content, the streaming video system is further configured to:
retrieve, from the resource queue of the messaging system, a signaling message enqueued in the resource queue by the first peer, wherein the signaling message represents a request to access the video content, and wherein the signaling message includes network availability information of the first peer used by the second peer in the establishment of the peer-to-peer connection;
enqueue, within the peer queue of the messaging system, a signaling response, wherein the signaling response includes network availability information of the second peer used by the first peer in the establishment of the peer-to-peer connection;
receive, at the second peer, a communication from the first peer indicating that the first peer has retrieved the signaling response from the peer queue;
and
using at least the network availability information of the first peer, establish the peer-to-peer connection between the first peer and the second peer.

9 more elements

A computer-implemented method, wherein the method is implemented by a computing system comprising a first peer providing access to a resource over a network via a peer-to-peer connection, the method comprising:

submitting a query to a messaging system distinct from the first peer, the query requesting signaling messages within a resource queue provided by the messaging system and associated with the resource, the signaling messages representing requests to access the resource that are enqueued within the resource queue by peers distinct from the first peer and from the messaging system;
obtaining, from the resource queue, a signaling message from a second peer, wherein the signaling message includes network availability information of the second peer used by the first peer in the establishment of the peer-to-peer connection, and wherein the signaling message identifies a peer queue, on the messaging system, that is associated with the second peer;
enqueuing, within the peer queue, a signaling response that is responsive to the signaling message, wherein the signaling response includes network availability information of the first peer used by the second peer in the establishment of the peer-to-peer connection;
receiving, at the first peer, a communication from the second peer indicating that the second peer has obtained the signaling response from the peer queue;
and
using at least the network availability information of the second peer, establishing the peer-to-peer connection between the first peer and the second peer.

3 more elements

One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed by a computing system comprising a first peer providing access to a resource over a network via a peer-to-peer connection, causes the computing system to:

query a messaging system distinct from the first peer for signaling messages within a resource message collection provided by the messaging system and associated with the resource, the signaling messages representing requests to access the resource that are enqueued within the resource queue by peers distinct from the first peer and from the messaging system;
obtain, from the resource message collection, a signaling message from a second peer, wherein the signaling message includes network availability information of the second peer used by the first peer in the establishment of the peer-to-peer connection, and wherein the signaling message identifies a peer message collection, on the messaging system, that is associated with the second peer;
add to the peer message collection, a signaling response that is responsive to the signaling message, wherein the signaling response includes network availability information of the first peer used by the second peer in the establishment of the peer-to-peer connection;
receive, at the first peer, a communication from the second peer indicating that the second peer has obtained the signaling response from the peer collection;
and
using at least the network availability information of the second peer, establish the peer-to-peer connection between the first peer and the second peer.
