Topics in network testing

nlike previous issues, we finally have an issue with contributions solely from the industry. This issue consists of one contribution from a test equipment provider and another from an operator. Both articles are embedded with industrial needs and real systems, while still maintaining some research flavor. Again, soliciting highly industry-oriented submissions from test laboratories, test equipment providers, and service providers is a promising way to go. We shall continue in that direction, but will not rule out other input from manufacturers and academia.
