Subject: Re: [Teas] [Netslices] terminology discussion network slicing

Hi,

1. Resources assigned to a slice are not necessarily virtual
[>DC] i don’t disagree with this

2.An LSP that is used to provide transport for a service (eg L2/L3 VPN)is not necessarily TE, and that doesn't make a VPN any less a VPN
[>DC] yes, this is right in theory, but if we see the slice as something with guaranteed performances (and it has to be in the 5G context), the VPN has to be bound to a TE tunnel…

3.Slice LS management is not done by IETF, YANG data modeling work is crucial to provide level of abstraction needed in multi-domain/multi-technology environment.
[>DC] Agree. And I guess you are referring just to the “transport” slice, which in turn is a portion of the Network Slice.Right?


In general, from ACTN prospective it is nothing different than resource allocation that meets constrains as requested by business logic.

Jari and myself have done 5G/slicing introduction to IAB during this week retreat and planning to follow up with the work in that area.

Cheers,
Jeff
