Delay for Gigabit Interfaces

I was wondering if someone can let me know how much latency/delay I will get in a solution that is a big ring with 460 Switches Catalsyt 2950G interconnected with 2 Gigabit Interaces (WS-G5486) each one.

This will not be an easy one to work out without testing, but basically you can have a specific metro solution for the 2950.


Please bear in mind that you will have various packet sizes which will naturally add delay.


This from CCO:

- 13.6-Gbps switching fabric

- 6.8-Gbps maximum forwarding bandwidth

- Forwarding rates based on 64-byte packets

- Cisco Catalyst 2950G-48: 10.1-Mpps wire-speed forwarding rate

- Cisco Catalyst 2950G-24 and 2950G-24-DC: 6.6-Mpps wire-speed forwarding rate

- Cisco Catalyst 2950G-12: 4.8-Mpps wire-speed forwarding rate

- Cisco Catalyst 2950T-24: 6.6-Mpps wire-speed forwarding rate

- Cisco Catalyst 2950C-24: 3.9-Mpps wire-speed forwarding rate


For what you are aiming at, i think a look here would be the best for you..
