Ultimately Fast File Transfer

HCP tools can achieve the ultimate in high-speed file transfers in any environment.

Our developed communication engine 'HpFP2' (High-performance and Flexible Protocol ver.2 *) enables significantly high-speed communication.

HpFP2 is a technology to maximally enhance the line usage efficiency with an innovative transmission control on the UDP layer by keeping the interface compatible with TCP sockets.

HpFP2 includes different effective controls to solve typical issues on the UDP communications, such as effective retransmission control, congestion control, transmission control, and flow control, which realizes remarkably high transmission efficiencies without significant drops in the communication speed in unstable or high latency network environments.

It can also realize that wide band networks over 1Gbps for HPC achieve high- speed file transfer, making the most of the bandwidth.

* HpFP was researched and developed by CLEALINK TECHNOLOGY Co., Ltd. and NICT (National Institute of Information and Communications Technology). CLEALINK TECHNOLOGY and NICT hold a patent (Patent Application No.6613742) about mechanisms for realizing fast communication on HpFP.

Effective Bundling Transfer of Many Files

The HCP tools realize effective file transfer for different sizes of files from small to large.

The most difficult case for FTP(File Transfer Protocol) widely used in transferring files, is to transfer many small files collectively.

On the other hand, the HCP tools efficiently and collectively process files with a memory buffer assigned for each one, which results in greatly shortening the processing time. The more files, the more effective.
