WAN Access to RouterTester using MS Terminal Services

When accessing lab equipment across a WAN (e.g. from home), broadband networks such as cable modem, DSL, and ADSL can introduce high communication latencies. These latencies are an accumulation of the following:

Transmission delays as a result of traversing physical distances
equipment forwarding (e.g. routers, gateways, satellites)
VPN security components (e.g. encryption/decryption)
Typical WAN latencies can be on the order of 125-150ms. In comparison, LAN networks present latencies of <5ms. These latencies can produce performance issues if they are compounded by communication protocols that require multiple acknowledgments.

Agilent recommends using Microsoft's Terminal Services (TS) for remote WAN access to RouterTester. This Technical Note describes the benefits of TS, compares it against other remote access methods, and shows how to set up TS servers and clients.

The Terminal Services client software needs to be installed on the client PC. The installation executable 'msrdpcli.exe' is available on the current RouterTester software release CD, and can also be downloaded from the Microsoft website.
