Responce Issue

[netlife]

Hi all,

I am facing problem in accessing a server.The scenario is

A--->B--->C--->D

Where,A=My Site. B=New York,C=Singapore,D=India.(Server)
I have been sudeenly facing the problem of Large Delay
of around 1598ms which was previously 540ms.
I had tried to trace that ip found that the delay occurs
between C and D router.But when a person from D ping my ip gets normal responce.
I am really wondering Why...?

Pls help.

Cheers,
netlife.

Have them do a tract from D to A. It is entirely possible that D is taking a different route to A than A is taking to D.

Thanx baddos,

I had a conference with them,traced the route from D.Same path followed.There is an expander box between C and D.And
the day before yesterday there was an outage on that link.
Would it be matter...?

Cheers,

A few things come to mind. If there was an outage the day before, I would say the most probably cause would be line issues. Have the telco come out and check the circuit. Insist they run all tests. Also check to sure line encoding hasn't changed.

If that proves uneventful, I would watch the interface details on the C and D router. Keep an eye out for errors in packets, and watch your buffers. If there is a WIC, check for state changes or bipolar inversions. if not, hopefully your CSU/DSU has an SNMP interface.

Thanx packettech.
I will certainly carry out the above checks.
Thank you.
