This Issue captures several related comments collected from Paris pertaining to Networking, entered against the original RM Chapter-4 Etherpad, including JB1, JB5, JB-7, JB-9 & JB16 - JB20. Per initial triage, these apply to original Chapters [4*], 6 and the RA, hence this issue will be replicated against each of those targets. Individual Issues can be broken off if/when further investigation warrants.

1 Action - talk about how many NICs and bandwidth (recommended physical networking infrastructure. Northbound NICs, East West NICs (for storage traffic). Southbound NICs for Management/OAM and PXE/ILO.
5 Not include Ethernet PHY speeds in a Virtual NIC context. Its misleading. A vNIC is connecting vSwitch. It's rate limiting not Ethernet PHY related.
7 Should the catalog specify: logical or physical network interfaces?
9 How to match the vNIC speed with a Physical NIC if they different in number and speed and we have vSwitch in-between?
16 Why virtual network interfaces connected with physical interfaces bandwidth? -> Throughput requirements from VNFs
17 #vNIC should not be part of the flavor
18 Action - Should include number of connections (attach rate to connections?)
19 Action - how to define virtual NIC requirements
20 How/do Virtual network interface options values add value?

From 4/9/2019 mtg:

1 (CH5) - Already addressed in H/W Profile (Table 5-16, "NIC Configuration") (ACTION: Change "Platform" to "Host").

7, #9 & #16 (CH4) - Replace Table 4-15 with a single table of aggregate (logical) bandwidth choices

5 & #17 (CH4) Number of vNICs is based on the number of extensions, and is not part of the Flavor (ACTION: Clarify language in paragraph 4.2.2)

18 Discuss w/ Rabi WRT bandwidth per interface vs. agg b/w per VNF

Committed PR #265 to resolve JB-5 & JB-17. Pending review.

Closing Summary:

JB-1 is resolved w/ PR #263
JB-7, 9 & 16 are resolved w/ PR #265 (1/2)
JB-5, 17 & 18 are resolved w/ PR #265 (2/2)
JB-19 will be addressed in a Networking section, to be added to RM CH-4 (post-Antwerp)
JB-20 requires clarification from the originator. Please step forward, and we can clarify/address.
