What's different? Resilient Packet Ring and Spatial Reuse Protocol

[sunyoung.song]

Hello, I am getting confused.

RPR and SRP, these technologies is very simaler.

but, I saw these feature guides.

It's described RPR's recovery time has 50ms.

but, feature guide of SRP is not described recovery time.

What is recovery time of SRP?

If SRP has 50ms recovery time so I should changed model Cisco 10700 to 7500.

Please Help.

Best regards.

Sunyoung. Song.

RPR is a network type or technology (IEEE 802.17 Standard). Cisco's name for that technology was DPT. It's only a market name. SRP is a MAC layer protocol developed from Cisco. This SRP is the underlying protocol which Cisco is using for their implementation of RPR or DPT.

So RPR, DPT or SRP have the same functions. Also the recovery time of 50ms.

There is no difference between Cisco 10700 and 7500. Both are DPT/RPR interfaces.

Hope this helps to clear your confusion.

My questions concering cisco12000 card "4 port OC-12c/STM-4c SRP ISE Line Card". If I use one double ring beetwin to routers (2 optical port) I will get one STM-4 full duplex bandwith or 2xSTM-4 ? Can I use only one port in this aplication if I have only one pair of fiber.
