5. Server SDK:

The Huddle01 Server SDK allows you to perform protected admin actions on your server side, like generating peer access tokens and starting and stopping meeting recordings and livestreams.

Infrastructure Improvements on the Huddle01 SDK V2:

1. Transition to uWebSockets for Improved Performance & Reliability:

Previously, when using socket.io with huddle01 SDK, we faced noticeable delays and lag in WebSocket connection creation. The library struggled with managing reconnections and maintaining connection states, often losing metadata during reconnection attempts, especially on weak network signals. Although socket.io automatically switched to HTTP long polling in such situations, it failed to upgrade back to WebSocket, resulting in higher latency and server strain. The SDK’s limited control over reconnections and state management prompted us to seek alternative low-level WebSocket servers for better control over the entire lifecycle of the WebSocket.

2. Global Region Aware Distribution with Zero Downtime Upgrades:

The RTC(real-time communication) Infrastructure has undergone significant changes to enhance its global distribution and scalability. It is now deployed across multiple geographical regions, ensuring optimal connectivity and performance for rooms.
We have also implemented mechanisms for Zero Downtime Upgrades to the infrastructure. This allows for new performance and security updates to be pushed to the infrastructure without ever affecting the user’s experience.

3. Multi Region Cascading:

Previously, Rooms were limited to one mediaserver, with its location determined by the first peer to join the meeting. This setup was efficient when participants were from the same region.

Previously, when people from distant places joined a meeting, they faced delays and used up more internet data, which made the meeting quality worse. To fix this, we introduced Multi-Region Cascading. This clever system spreads the meeting across many servers in different places. It connects each person to the nearest server, which makes the meeting smoother, improves the audio and video quality, and uses less internet data.

This improvement not only made our users' experience better but also let us expand our meetings more easily. Now, we can handle more people in the same meeting by spreading it across many servers in different places.

improvements the Huddle01 SDK v2 provides:

Global coverage
Higher scale
Smoother reconnection
Zero-downtime deployments
Improved developer experience

Huddle01 SDK V2 Client Improvements:

After huddle01 SDK v2 has been available to our community for the past 1.5 years, huddle01 SDK V2 have received a lot of feedback regarding improving the developer experience, ease of integration, and numerous feature requests. With Huddle01’s SDK v2, aim is to address this feedback and make improvements accordingly.

Huddle01 SDK V2 performed a major internal code cleanup on the client-side SDKs, which involved eliminating the use of third party state management. In version 1, we relied on XState for this. Now, huddle01 SDK V2 utilise simple event listeners and use that to handle local states internally to ensure reactivity in the SDK.
Huddle01 SDK V2 transitioned from using JSON to Protocol Buffers to reduce the size of message payloads for interactions between the client and server. This change also allowed huddle01 SDK V2 to maintain consistent schema and cross-compatibility across all current and upcoming clients like (Flutter on Dart) due to automatic type generation with Proto files.
Recording and live-streaming can now be initiated with a single API call on huddle01 SDK V2.
Huddle01 SDK V2 introduced Functions and Hooks to provide more precise control over media source selection. i.e. Introduced the concept of Remote & LocalPeer to cater to simpler developer experience while allowing developers to have granular control over each stream from every peer.
Huddle01 SDK V2 removed the Lobby concept in favour of a simpler and seamless joining flow.
AccessTokens for Peers were added to allow developers to have granular permission control. This enables developers to incorporate custom business logic and implement first-class authentication control using any server-side authentication method.
Custom Metadata is now available for the Room , individual Peers and their media streams, enabling more creative and custom use cases such as MetaVerse and Webinars.

There are several neat changes included in the SDK v2 Docs. Huddle01 SDK V2 main objective was to enhance the SDK’s reliability, ease of integration, and scalability. Huddle01 SDK V2 put great emphasis on making it more robust and capable of handling large-scale communication needs. At the same time, huddle01 SDK V2 wanted to ensure that the SDK remains flexible and adaptable to accommodate innovative and non-traditional use cases in Real Time Communication.

The Next Phase of Huddle01: Roadmap to People-powered Communication.

The decentralized people-powered communication network is designed to provide ultra-low latency, enhanced data privacy and upto 95% cost savings on data transfer & compute.

In 2020, Huddle01 set on a journey to democratize WebRTC that would enable more open, censorship-resistant, private, and secure communication across borders, devices, identities, and users.

In the last 3 years, Huddle01 have come a long way. Huddle01 started with the demand-first approach, served 2M+ audio/video minutes to over 30K users [just in 2023] across multiple apps, platforms and networks leveraging our infrastructure.

In 2023, Huddle01 launched our Infrastructure - “SDKs & APIs” which can enable audio/video capabilities for any application [from socials to gaming to live video commerce] and users. This marked the completion of our Phase 2 where Huddle01 transitioned from Platform → Infrastructure layer. Huddle01 took demand-first approach and have been able to establish a recurring demand of minutes on our Network across different domains like ed-tech, socials, productivity & collaborative toolings, and others.

Now is the time to switch the gears, and get focused on how Huddle01 launch their DePIN for RTC [dRTC network] and hand over the power of supplying RTC minutes to the Node operators, and get closer to our mission of creating a “People-powered Communication Network”.

For 2024, Huddle01 have one clear mission: Launching HUDDLE01 DePIN for RTC [dRTC Network] & Protocol which will enable open, secure, private, and immersive communication for everyone.

Huddle01 mission is an ambitious one, and it isn’t the kind which can be achieved in one go. It will be a journey of progressive decentralization, with a phase-wise unveiling of our Network & Protocol.
