MSRP (Message Session Relay Protocol) protocol stack is an SDK developed by Juphoon, compliant with RFC4975 standards and its extended specifications. The protocol stack enables such services as data and file transfer defined by the IETF RFC 4975 document. It features high-speed file transfer and low bandwidth occupation via P2P transmission and is based on TCP. It is suitable for real-time services such as instant message (IM), file transfer, image sharing, game and service control.

Our MSRP protocol stack is a part of Juphoon’s protocol suite, adding high-speed data transmission capabilities to IMS-based services, such as file transfer, instant message (1-1 chat, 1-n chat and group chat), image sharing and wireless PTT control. It is designed to provide simple and intuitive interfaces, enabling rapid service integration and high-speed transfer.
