[Teas] SNMP and network slicing

[Adrian Farrel <[e-mail]>]

Hi,

Kenichi pointed out that the current version of the slicing draft has a
couple of mentions of SNMP and that this might no longer be appropriate
given the IESG statement at
https://www.ietf.org/about/groups/iesg/statements/writable-mib-module/ 

I agree.

I propose to remove all mention of SNMP from Section 5.2 unless anyone
objects.

The text that will change is:

OLD
   There are several IETF-defined mechanisms for expressing the need for
   a desired logical network.  The NBI carries data either in a
   protocol-defined format, or in a formalism associated with a modeling
   language.

   For instance:

   o  Path Computation Element (PCE) Communication Protocol (PCEP)
      [RFC5440] and GMPLS User-Network Interface (UNI) using RSVP-TE
      [RFC4208] use a TLV-based binary encoding to transmit data.

   o  Network Configuration Protocol (NETCONF) [RFC6241] and RESTCONF
      Protocol [RFC8040] use XML abnd JSON encoding.

   o  gRPC/GNMI [I-D.openconfig-rtgwg-gnmi-spec] uses a binary encoded
      programmable interface;

   o  SNMP ([RFC3417], [RFC3412] and [RFC3414] uses binary encoding
      (ASN.1).

   o  For data modeling, YANG ([RFC6020] and [RFC7950]) may be used to
      model configuration and other data for NETCONF, RESTCONF, and GNMI
      - among others; ProtoBufs can be used to model gRPC and GNMI data;
      Structure of Management Information (SMI) [RFC2578] may be used to
      define Management Information Base (MIB) modules for SNMP, using
      an adapted subset of OSI's Abstract Syntax Notation One (ASN.1,
      1988).
