The Samsung Chord is a brilliant and fun way to share content and user events in real-time between devices. The Samsung Chord (Chord) SDK allows application developers to develop local information-sharing applications without a detailed knowledge of networking.
Chord enables simple real-time sharing without the cloud!
- Easy discovery and connection with nearby devices
- Real-time experiences between multiple devices
- Fast peer-to-peer connection, without the need of a server
- Decentralized networks where peers can come and go at any time
Chord quickly connects nearby devices so you can create shared, real-time experiences like collaborative interaction, multi-player games and media sharing. Without using the cloud or server, it instantly supports sharing 1-to-1, 1-to-many or many-to-many.
Devices running Chord-based applications discover each other using a UDP broadcast based discovery, and then use a TCP-based protocol stack to create a reliable, peer-to-peer local communication network. This network can be used to share data, including text, binary messages and files, with selected members of the network.
Chord SDK helps you create a group with multi-devices in real-time, automatically, requiring no manual processing of devices which join or leave the group.
