udp_copy2 Description

udp_copy2 implements plaintext non-interactive data transfer over UDP/IPv4 with a preset transfer rate. udp_copy2 project consists of two executables, udp_send2 and udp_recv2, implementing plaintext non-interactive data transfer over UDP/IPv4 with a preset transfer rate. On lossy links, it yields better throughput than TCP-based transfers.It may also be used for smooth user space throttling. It dedicates a mode to SNAT/MASQ, so the receiver can initiate transfer from behind a firewall. It features a very precise user space packet scheduler.It handles SIGSTOP in a rational way. It only transfers in one direction for one invocation. It needs and uses no synchronous I/O multiplexing. Shell access is required on both ends. The package also contains the auxiliary multi-threaded tool "bigpipe", which can be used to reduce pipeline latency.What's New in This Release:· The package has been ported to Cygwin 1.5.19-4.· Some messages are more user friendly now.· Several small portability and documentation related fixes have been applied against bugs which likely manifested nowhere.· The multi-threaded program "bigpipe" has been added for Unix98 platforms and Unix95 platforms with Posix Threads.· It promotes asynchronicity among members of a pipeline.· It helps in advancing through regular files on NFS-, SMB-, or USB-mounted devices.· This benefits udp_copy2 directly because it requires very low latency on stdin/stdout.· The version numbering has been sanitized.Installation:After make finished, check the executables: $ ls -l udp_recv2 udp_send2 bigpipeSimply copy the executables to a proper place, for example: $ cp -i -p udp_recv2 udp_send2 bigpipe $HOME/bin
