Re: fragmentation/reassembly functions at link layer
Hi,
I have got the source code from Lloyd Wood (written by Hashimoto and
Sarikaya) for segmentation/reassembly. I find this agent-based approach
a little bit inflexible. Principally, I think ns should support packet
generating at link layer (that is, some classes derived from class
Connector or LinkDelay can generate packets) so that it supports the
implementaion of some protocols at link-layer. I have actually found an
example in mac-802_11.cc. The mac layer creates packets and send them to
the other end. But the hdr_cmn::uid_ field is set to 0 here. My question
is that what is the function of uid_ and whether we can trace packets
with uid_=0 using nam.
Thanks in advance.
Regards,
Nguyen Huu Thanh
