[Xorp-hackers] Questions on the architecture

[theo29 the29]

I have two questions on the XORP architecture which I hope someone can 
answer:

1. The architecture is based on a single threaded event loop, that divides 
its time doing a select() on all its file descriptors (in the selector 
list), and executing expired timer events. A select() is one of the more 
expensive things you can do in the kernel, so I was wondering if you had 
thought something about the scalability of that approach (for example in 
terms of number of protocols communicating with the finder server). Did you 
not consider asynchronous IO?

2. What is the purpose of the SocketServer class. Should protocols not open 
their own sockets, but rather deligate that to the XRL target implementing 
the socket4.xif (which I belive is executed in the FEA process now)? Why 
deligate this task?

Best regards
