End-to-End Network Service QoS – Part 2

In Part 1 of this article, I talked about how to design access QoS with sap-ingress and sap-egress QoS constructs from Nokia's Service Router for a coast-to-coast ePipe MPLS network service to support triple-play traffic. I showed how to classify the triple-play traffic at the ePipe's sap-ingress and map the traffic onto different Forwarding Classes (FC) for the … Continue reading End-to-End Network Service QoS – Part 2

End-to-End Network Service QoS – Part 1

Before the arrival of MPLS and the advance in silicon technology for ASIC and network processors in early 2000s, many carriers ran multiple single-purpose networks such as TDM, ATM and IP to support their video, voice and data network services. Some enterprises attempted to consolidate their triple-play traffic onto a single IP network. However, due to the silicon technology and QoS … Continue reading End-to-End Network Service QoS – Part 1
