When need a better messaging protocol for my project DTCrawler. I find these 2 new implementation. After study them, especially the book Networks for Grid Applications I choose UDT
1. built upon the UDP (which is my preference)
2. Provide the flow/congestion management, which it is necessary for the application
The difference is like this.
"UDT borrows the messaging and partial reliability semantics from SCTP. However, SCTP are specially designed for VoIP and telephony, but UDT targets general purpose data transfer. UDT unifies both messaging and streaming semantics in one protocol."
