Need advice for parallel requests

[Jaguar Xiong]

Hi,
    We are considering using thrift for peer to peer communicaiton, the 
system contains multiple nodes, and each node could send multiple 
requests (without waiting for response from previous requests) to any 
other nodes.
    But looking into message definition, I could find message 
type(call,response,exception,etc), sequence number, which seems fit the 
purpose. But I don't know if any of the existing Server (TSimpleServer, 
TNonblockingServer, etc) really fit my need.
    Could you share some ideas on existing components, or any starting 
point for implement such feature?

Thanks!
