I should think that you can use Multilink PPP (MPPP) to bundle multiple SDSL links together. Never tried it on SDSL but it works well on serial lines and ISDN.   As I recall each packet gets split across all the parallel links so you get good latency...

Hi,"@Douglas -- our core switch is of 3750G series. Im getting high latency only when i ping gateway of any vlans which are created on core switch. When i ping to other devices which are behind or after core switch i get proper response 1ms."I am say...

Let me re-state the "problem".Ping Round Trip time from a PC to a "gateway"  (perhaps a Cisco 2960) alternates between 3ms and 200ms.All other ping tests on network are 3ms or better."i guess its something related to core switch becoz when im pinging...

That all looks fine to me. The "missing" traceroute reply is from the far end router. Since it is terminating the VPN it will not "see" the traffic in decrypted form.Look elsewhere for your issue.In general networks cannot store packets for very long...

One option might be to use the "null" encryption algorithm for your troubleshooting excersise. Obviously you would need to assess the security risks of that approach. I am not sure how that might help you to troubleshoot poor performance though:)Obvi...
