Deploying diffserv at the network edge for tight slas, part I
John B. Evans, Clarence Filsfils · IEEE Internet Computing · 2004
In the first of a two-part series, we review industry best practices for designing, validating, deploying, and operating IP-based services at the network edge with tight service-level agreements (SLAs). We describe the important SLA metrics for IP service performance and discuss why Diffserv is the preferred technology to achieve these SLAs.
