This draft is a work item of the Service Function Chaining WG of the IETF. Title : Network Service Header (NSH) Authors : Paul Quinn Uri Elzur Carlos Pignataro Filename : draft-ietf-sfc-nsh-28.txt Pages : 40 Date : 2017-11-03 Abstract: This document describes a Network Service Header (NSH) imposed on packets or frames to realize service function paths. The NSH also provides a mechanism for metadata exchange along the instantiated service paths. The NSH is the SFC encapsulation required to support the Service Function Chaining (SFC) architecture (defined in RFC7665).

The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/ Technical Summary This document describes a Network Service Header (NSH) inserted onto packets or frames to realize service function paths. NSH also provides a mechanism for metadata exchange along the instantiated service path. NSH is the SFC encapsulation required to support the Service Function Chaining (SFC) Architecture (defined in RFC7665). Working Group Summary The working group has had many discussions on this document. Many individuals from many companies have helped bring together this solution. Over the last 9 months significant effort has gone into fixing issues raised by earlier reviews. While there is still some disagreement (such as on the fact that the WG selected TTL mechanism is a compromise with some accepted imperfections), all technical limitations are identified in the document and dealt with in fashions acceptable to the rough consensus of the working group. Document Quality There are multiple implementations of this work, some from open source and some proprietary.

This draft is a work item of the Service Function Chaining WG of the IETF. Title : Hierarchical Service Function Chaining (hSFC) Authors : David Dolson Shunsuke Homma Diego R. Lopez Mohamed Boucadair Filename : draft-ietf-sfc-hierarchical-05.txt Pages : 26 Date : 2017-11-13 Abstract: Hierarchical Service Function Chaining (hSFC) is a network architecture allowing an organization to decompose a large-scale network into multiple domains of administration. The goals of hSFC are to make a large-scale network easier to reason about, simpler to control and to support independent functional groups within large network operators.

It provides a small elaboration on the NSH document. There seemed to be good working group acceptance of the work, although we never formally adopted it. The WG Chairs have determined that it makes sense to go directly to a WG last call on this document. Given that there are two last calls an two calls for working group adoption (see following emails) we are allowing 3 weeks for these calls. Please respond with either support or objection to the WG delivering this document to our area director for publication as a Proposed Standard RFC. We need to see feedback. Silence does not imply consent. We would prefer feedback with content.

NEW: Like any NSH packets, such packets are contained ^^^^^^^^^^^^^^^^^^^^^^^^^^ within the SFC-enabled domain. (3) Point to the section where same use cases are described: OLD:=20 This document illustrates some of the functions that may be achieved or enhanced by this mechanism, but it does not provide an exhaustive list of use cases, nor is it intended to be definitive about the functions it describes. =20 NEW: This document illustrates some of the functions that may be achieved or enhanced by this mechanism, but it does not provide an exhaustive list of use cases, nor is it intended to be definitive about the functions it describes (refer to Section 5).=20 ^^^^^^^^^^^^^^^^^^^^=20 (4) Delete this text:=20 It is expected that other documents will describe specific use cases in more detail and will define the protocol mechanics for each use case. (5) Add this text at the end of the section: NEW: This document uses the terms defined in [RFC7665] and [I-D.ietf-sfc-nsh]. * Section 2: (1) Merge Sections 2 and 3 + change the title accordingly OLD:=20 The Network Service Header NEW: Next Protocol 'None': Specification & Behavior (2) NSH is already cited in the document OLD: The NSH is defined in [I-D.ietf-sfc-nsh]. It includes a field called ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ "Next Protocol" that is used to indicate the nature of the payload NEW: The NSH includes a field called "Next Protocol" that is used to=20 indicate the nature of the payload (3)=20 OLD: This document defines a new value for the "Next Protocol" field. NEW: This document defines TBD1 value for the "Next Protocol" field. * Section 3: (1)=20 OLD:=20 3. Processing Rules NEW:=20 2.2. Processing Rules (2) Before describing the processing behavior, the reader may first need to= know about the triggers for sharing such information. Please position this= two paragraphs at the beginning of the section:=20 A packet with no payload data may be inserted at the head end of an SFP (such as at a Classifier) and may be easily forwarded by an SFF or SFI on the SFP using the processing rules defined in [I-D.ietf-sfc-nsh]. A packet with no payload may also be generated by an SFC-aware SFI as a result of processing an incoming packet (i.e., triggered by a condition arising from processing a normal NSH packet with a payload). In such cases, the SPI/SI can be inherited from the original packet or can be set according to information supplied through the control plane, or management plane, or indicated by information carried in the metadata of the data packet. This document does not further specify the triggers to generate an NSH packet with a "Next Protocol" set to "None". (3) Insert this NEW text right after the first two ones: Some setup is need= ed before a node can generate a packet with None:=20 NEW: An SFC-aware node may be instructed by the control plane about=20 the conditions under which such packets are to be generated.=20 Further, the control plane is responsible for providing the required information to generate the corresponding NSH packet (e.g., SFP=20 Identifier to use, TTL). (4) Update this text to insist that one or multiple piece of metadata can b= e inserted: OLD: o MUST create a packet carrying an NSH and the desired metadata NEW: o MUST create a packet carrying an NSH and the desired metadata; one or= more metadata fields may be included. (5)=20 A transit node (SFF, SFI, or Classifier) receiving a packet with "Next Protocol" indicating "None" MUST NOT attempt to parse or process beyond the end of the NSH, but SHOULD process the NSH and the metadata as normal. I wonder whether "normal" can be expanded a little bit here. For example, i= ndicate what to do if an intermediate node is instructed to strip a metadat= a, and no metadata field is left. Should the packet be forward even if no m= etadata field is included of it should stop forwarding. (6) Add this text at the end of the section: NEW: In deployments where Next-Protocol "None" is not desired,=20 administrators SHOULD instruct SFC-aware nodes to discard packets with Next-Protocol "None". =20 * Section 6 (1) Simplify this text:=20 OLD: The procedures for handling NSH fields with unknown values are set out in [I-D.ietf-sfc-nsh]. In particular, section 2.2 of [I-D.ietf-sfc-nsh] describes how elements of an SFC enabled network handle unknown values of the "Next Protocol" field. SFC-aware nodes that do not understand the meaning of a value contained in the "Next Protocol" field of the NSH are unable to parse the payload. Such nodes silently drop packets with unknown "Next Protocol" values unless explicitly configured to forward them. NEW: SFC-aware nodes that do not understand the meaning of a value contained in the "Next Protocol" field of the NSH are unable to parse the payload. Such nodes silently drop packets with unknown "Next Protocol" values unless explicitly configured to forward them=20 (Section 2.2 of [I-D.ietf-sfc-nsh]). (2)=20 o SFC Proxies will drop the packets o SFIs will most likely drop the packets - Use the same wording for SFC-aware SFs and SFC proxies given that both ca= n update/insert/strip metadata. (3) o Reclassifiers will most likely drop the packets - Purely speaking, these are classifiers according to the SFC architecture. (4) Not sure to understand this text:=20 It is a general processing rule for all forwarders that they SHOULD NOT attempt to send packets with zero length, and packets with the NSH "Next Protocol" set to "None" are expected to have zero payload length. (5) Please delete this text: In any case, SFC-aware nodes at the end of an SFP MUST NOT forward packets with "Next Protocol" set to "None". Because it is redundant with the text in Section 3: Such nodes MUST NOT forward packets with "Next Protocol" indicating "None" even if there are some bytes after the NSH. * Section 5: (1) Please add this text as a preamble: Communicating the exact value of a = given context information is only one step in the process. Some setup is re= quired to instruct SFC-aware nodes about allowed context information to sha= re, how to consume it, what do after consuming it, and so on.=20 NEW: As discussed in [I-D.ietf-sfc-control-plane], the control plane is=20 responsible for instructing SFC-aware nodes about the metadata allowed for a given SFP, the semantic of such data, the behavior to follow=20 after consuming metadata, the order of processing metadata, etc.=20 Such considerations are assumed to be in place within an SFC-enabled domain. The following focuses on the provisioning of allowed metadata values for a given SFP. =20 * Section 5.1: the metadata can be provisioned on other nodes than an SFC-a= ware SF: OLD:=20 Per-SFP metadata is metadata that applies to an SFP and any data packets on that SFP. It does not need to be transmitted with every packet, but can be installed at the SFIs on the SFP and applied to all packets on the SFP. It could be installed by inclusion in the NSH of a data packet sent on the SFP, by out of band control or management plane mechanisms, or by separate metadata-only packets using "Next Protocol" set to "None" as described in this document. Per-SFP metadata-only packets may be sent along the path of an SFP simply by setting the correct SPI in the NSH, and setting the SI to the correct value for the hop of the SFP at which the metadata is to be introduced. Classifiers and reclassifiers will know the correct SI values to be used from information supplied by the control or management plane as is the case for NSH packets with payload data. NEW: Per-SFP metadata are metadata that apply to an SFP and any data ^^^^ ^^^^^^ =20 packets bound to that SFP. It do not need to be transmitted with every ^^ packet, but can be provisioned on the classifier, SFC-aware SFs, and SFC= -aware proxies for this SFP and applied to ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^= ^^^^^^^^^^^^^^ all packets on the SFP. It could be provisioned by inclusion in the ^^^^^^^^^^^ NSH of a data packet sent on the SFP, by out of band control or management plane mechanisms, or by separate metadata-only packets using "Next Protocol" set to "None" as described in this document. Per-SFP metadata-only packets may be sent along the path of an SFP by setting the correct SPI in the NSH, and setting the SI to the correct value for the hop of the SFP at which the metadata is to be introduced. SFC-aware nodes (e.g., Classifiers) will know the corre= ct ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^=20 SI values to be used from information supplied by the control or management plane as is the case for NSH packets with payload data. * Section 5.2: Idem as Section 5.1 * Section 5.6:=20 OLD:=20 Per-packt metadata is metadata that applies specifically to a single ^^^^^^ ^^ ^^^^^^^^ =20 payload packet. It informs an SFI how to handle the payload packet, and does not apply to any other packet. The mechanisms described in this document are not applicable to per- ^ ^^^^ packet metadata because, by definition, if the "Next Protocol" indicates "None" then there is no packet following the NSH for the metadata to be associated with. NEW: Per-packet metadata are metadata that apply specifically to a single payload packet. It informs an SFI how to handle the payload packet, and does not apply to any other packet. Evidently, the mechanism described in this document is not applicable to= per- ^^^^^^^^^^ packet metadata because, by definition, if the "Next Protocol" indicates "None" then there is no packet following the NSH for the metadata to be associated with. * Section 6: SHOULD be would be more appropriate here:=20 OLD: The amount of packets with "Next Protocol" set to "None" on an SFP MAY be rate limited at any point on the SFP to provide additional security. NEW: The amount of packets with "Next Protocol" set to "None" on an SFP SHOULD be rate limited at any point on the SFP to provide additional security. * Section 7:=20 OLD:=20 IANA has been requested to create a registry of "Next Protocol" values in [I-D.ietf-sfc-nsh]. This document requests IANA to allocate a value from that registry to indicate "None" (TBD1 in this document). It is strongly suggested that a value of 0 (zero) be assigned. NEW: This document requests IANA to allocate a value from the=20 "NSH Next Protocol" registry at https://www.iana.org/assignments/nsh/nsh= .xhtml#next-protocol (TBD1 in this document): Next Protocol Description Reference 0x00 None [This-Document] Thank you.

I was concerned about sending too many requests to the WG. However, as noted by you and Med, there is a strong relationship with the two MD-1 drafts and the MD-2 draft. As such, I will send an adoption call for the MD-2 draft later today.

I believe the intent is to leave it free to the implementer and operator (p= er "local policy"), but I feel like I had to read between the lines. Could we add a paragraph like this somewhere in section 3? NEW: For backwards compatibility, SFIs are permitted to discard payload-none = NSH packets.=20 However, SFIs SHOULD forward payload-none NSH packets (according to the = normal rules of decrementing SI and sending to SFF).
