Serverless Signaling via Message Queues for P2P Session Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peer-to-peer communication systems require a dedicated signaling server for establishing connections, leading to inefficiencies due to unused computing resources and limited scalability.
Innovation Solution
The use of message queues within a message queuing service allows peers to communicate directly for signaling, eliminating the need for a dedicated signaling server and enabling 'serverless' signaling, combined with an on-demand code execution system for efficient resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated signaling server is used to facilitate peer-to-peer communication, then connection establishment is reliable, but computing resource usage increases and scalability is limited
Solution Approach 1:
The patent extracts the signaling function from the dedicated signaling server and relocates it to message queues. Peers directly publish and subscribe to signaling messages through the message queue system, eliminating the need for server-mediated signaling while maintaining connection establishment reliability
Solution Approach 2:
The message queue system serves as an intermediary between peers for signaling communication. Instead of requiring a dedicated signaling server, peers use the existing message queue infrastructure to exchange signaling messages, achieving serverless signaling while maintaining reliability
2Adaptability or versatility
If a dedicated signaling server is deployed, then signaling functionality is available, but system scalability is constrained
Solution Approach 1:
The patent makes the message queue system universal by using it for both traditional message passing and signaling functions. This multi-functionality eliminates the need for separate signaling server infrastructure, thereby improving scalability while reducing system complexity
Solution Approach 2:
The patent merges the signaling function with the existing message queue infrastructure. By combining these functions into a single system rather than maintaining separate signaling and messaging infrastructures, the system achieves better scalability and reduced complexity
3Reliability
If signaling messages are exchanged through a signaling server, then connection establishment is reliable, but resource utilization is inefficient due to unused computing resources
Solution Approach 1:
The patent enables peers to serve their own signaling needs by directly publishing and subscribing to signaling messages through message queues. This self-service approach eliminates the need for dedicated signaling server resources, reducing computing resource waste while maintaining signaling reliability through direct peer-to-peer message exchange

AI summary
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.
