This page is intended to describe use of HCoS inside Circuit Cross-Connect - CCC environment. In order to guarantee dedicated bandwidth along CCC path it is necessary to apply traffic classifiers at the ingress and hierarchical schedulers and shapers at the egress. Using 2 Juniper MX204 routers and 2 DELL PowerEdge R520 servers we will simulate production GTS scenario. These devices are regular part of Prague's laboratory on which it is allowed access with known credentials.
