[ns] Reg timestamps!!

[Archana Krishna <KArch@UH.EDU>]

Hi,
I am trying to implement an admission control algorithm on ns.I am
using udp flows. I need to record the time when the packet
is generated by the source. This recorded time should be accessible at the
point the packet reaches the destination.Having a time stamp on each
packet solves the problem.

There is hdr_cmn :

struct hdr_cmn {
        packet_t ptype_;                // packet type (see above)
        int     size_;          // simulated packet size 
        int     uid_;           // unique id
        int     error_;         // error flag
        double  ts_;            // timestamp: for q-delay measurement
        int     iface_;         // receiving interface (label)
        int     direction_;     // direction: 0=none, 1=up, -1=down
        int     ref_count_;     // free the pkt until count to 0

Do you think I can use this for time stamping the udp packets I
generate????

Can anyone please answer my question.
Thanks in advance.
