MetroEthernet - QoS

Hi

What options do I have when implementing QoS in a MetroEthernet network.

We plan to run the following

an MPLS core, with non-mpls access rings.

We are looking to implement QinQ

Thanks

The following document talks about the QoS features available for a Metro Ethernet environment.

For MPLS core and non-MPLS access, check out the documents in the following link :

Re: MetroEthernet - QoS

Hi Kevin,

At a high level, one methodology to consider is to make sure you: classify, mark, police, queue and avoid congestion where applicable.

In a more detailed perspective, classification/marking and policing start to happen on the edge of the network where queuing/congestion avoidance happen as traffic starts to move through various parts of the network.

One of the first area's to consider is how you will classify traffic on ingress into the network and how you will mark traffic that conforms to the policy, such as, for example, classify on DSCP and mark the COS bits.
