Att---> Cust A ---> Cust B --->Cust c
We are Cust A and we get service from ATT and we provide service to Cust B where they have ftp server and cust B provides service to Cust C and When cust c is trying to download a file from ftp server,, speeds are 200KB and when cust B starts the connection or transfer,, speed is 5 meg, where as the link is of 50Meg.
We trid to check our network first and did not find any issue. and the traceroute shows the hop after our network which is to ATT is taking a long time... 30 msec to 300msec.
we even tried to provision another port at cust B and tried to hit the router at our end as we are providing service and the speeds are 40 Meg. and we ruled out our network.
Cust b and C are at the same location and switches in between.
We thought there might be firewall isue and no bandwidthe limiting any where in the network. no firewall isuue.
Even http speeds are low ,,
ATT claims,, there is nothing wrong,, we thought the way they are routing might be the issue.
We are out of ideas,, can u guys help us out coz cust c is very dissappinted with speeds.
