UDT穿透在P2P开发平台中的应用

UDT Penetration in the P2P Application Development Platform

目前众多的P2P软件都采用TCP/UDP协议的穿透,其中穿透的方式ALG、MIDCOM、STUN、TURN、FullProxy等。该文针对这些协议的各种穿透进行了分析和总结,提出了基于UDT传输协议的NAT穿透。它能够使P2P软件在穿透中实现可靠连接和动态设置QoS。通过在本公司自主开发的P2P平台[1]中的应用可以发现UDT穿透可以在数据传输中充分的利用有限的带宽。

Presently,most of the P2P softwares are using TCP/UDP while penetrate the different NATs in internet.The way of penetration are different,which includeing ALG, MIDCOM,STUN,TURN,FullProxyand so on. We set up a new NAT penetration based on the UDT while analysing and summarizing these kinds of penetrating technology.It can create the reliable connection while penetrate the dif- ferent NAT and set the QoS dynamically. Through the P2P platform which use the UDT NAT penetration we find it can use the limited bandwidth adequately in the data transmission.
