Hi there,
We are developing a solution to allow our Chinese branch to access SAP ECC system here in the US. The first task is to pick the right network communication protocol/technology as the enabler. Our initial thought is to use the VPN technique for the simplicity reason and low cost. But our Chinese office has a concern regarding the lateness sensitivity of the SAPGUI application. Then they recommend Frame-relay technique based connection, which is definitely costly than the VPN one.
So, if someone out there has the same challenge and got some success stories to share, I would like to thank you in advance. Any help is very much appreciated.
Best regards,
Joshua Z.
