Folks,

Do we have general consensus that we want the compression mechanism to replace the EVPN VXLAN header? If so, the VNI in the VXLAN header is 24-bits long. So, the Service Scale requirement should be 2**24 (i.e., 16.7 million).

                                                                                                                             Ron

I said more then >16bit and 1Million was something I know someone deployed. So I would say lets list what we have as a customer requirement somehow

Wim,

Two to the sixteenth power is only 65k. If you want to support 1 million services, you need 20 bits, not 16.

The EVPN VNI is 24-bits long. Given that EVPN is a fastest growing VPN service, I suggest that we may actually need 24 bits.

                                                                                                               Ron

Subject: REQ-7-27-SVC-SCALE-00

Short Name: Service scale

Description: The compression mechanism must support > 1Million services (>16bit)

Rationale: Some network operators deploy networks which requires > 500K services.

Metric: The compression mechanism allows to work in an environment that support this scalability.
