t2stack

Description

t2stack is a collective name for the simplified network protocol stack and its supporting middleware for intelligent terminal scenarios, which mainly provides two core transmission capabilities: file and stream, and is suitable for multiple operating system platforms.

File transfer capability: Mainly for file sharing and cloning scenarios, compared with the Linux kernel protocol stack used before the application, the innovative protocol of t2stack can provide higher bandwidth utilization and lower latency than TCP in the WIFI environment, and provide a variety of optimizations in file transfer, such as large and small file collaboration, small file packaging and other purposes.

Streaming capability: Mainly for video streaming and audio streaming scenarios, it implements three competitive solutions, including semi-reliable transmission, adaptive bandwidth evaluation bitrate, and dynamic caching for weak network detection, to optimize user experience.

Introduction to the main interface functions

File Transfer

1. Establish a connection NSTACKX_DFileServer:Create a file transfer server NSTACKX_DFileClient:Create a file transfer client NSTACKX_DFileClose:close file trasfer
2. File transfer NSTACKX_DFileSendFiles:client send files NSTACKX_DFileSetStoragePath:server set file's storage path NSTACKX_DFileSetRenameHook:Set a callback function on server end to rename files with the same path and the same file name to prevent them from being overwritten
3. Get and Set Capabilities NSTACKX_DFileGetCapabilities:Get DFile's Capabilities NSTACKX_DFileSetCapabilities:Set DFile's Capabilities
4. Interactive processes

Stream Transfer

1. Initialize and destroy FtInit:initialize the VTP/FillP stack FtDestroy:deinitialize the FillP stack
2. Establish a connection FtSocket:create socket FtBind:bind socket and address on server FtListen:listen for connections on a socket FtAccept:acccept a connection on a socket FtConnect:Initiate a connection on a socket
3. Send and recv FtSendFrame:Send a video frame on a socket FtRecv:receive messages from a socket
4. Close a connection FtClose:close the socket connection and releases all associated resources
5. Interactive processes
