Best practices for Voice over MetroRing

[heespino]

Hi, We have installed a MetroRing Gigabit Ethernet using 3550 and 6500 Catalyst switches. Today, only data is running, but looking at tomorrow, when voice/video be requested, I am trying to find some best practices for QoS or traffic classification. If you can point me to some of them will be great.

Hi,

You might also find those useful: " LAN QoS"

and "Cisco AutoQoS White Paper"

http://www.cisco.com/en/US/tech/tk543/tk759/technologies_white_paper09186a00801348bc.shtml

as well as "Configuring QoS" for Catalyst 6500 switches

http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_guide_chapter09186a008007fb2b.html

The most comprehensive starting point will be: "Quality of Service (QoS)"

Hi,

Apart from the QOS part ..

Important factor for metro is dynamic failover from active to backup path in ring environments.

Most of the SP uses RSTP or MSTP to achieve this at L2 level on their metro E rings , which has higher failover delay .

If you are planning to give carrier grade voice services over metro ring , look forward for induction of RPR based rings in ur Metro

Thanks and Regards
