Based on the presentation by Greg Mirsky and discussion in= rtgwg and elsewhere, I have decided to charter a fast-moving Routing Area = design team to work on Overlay OAM.

The charter is below:

In the Routing Area, several = WGs (e.g. NVO3, BIER, and SFC) are working on relatively new encapsulations= to create overlays. These overlay or service encapsulations are transport-= independent since they may be over different transports or at different lay= ers in the networking stack. Each WG is starting to discuss what OAM and to= ols need to be developed (see draft-ietf-sfc-oam-framework-00, draft-ietf-b= ier-oam-requirements-00, and individual drafts in NVO3). With increasing us= e of overlay and service layer tunnels, extensions to traceroute to allow v= isibility into multiple layers are being discussed (e.g. draft-nordmark-nvo= 3-transcending-traceroute-01).

There is an opportunity to propose pr= otocols and methods to provide Overlay OAM in a sufficiently generic fashio= n that they can meet the requirements and be applied to at least BIER, NSH,= VXLAN-GPE, GENEVE, and GUE. A truly successful result would also be applic= able to other technologies.

This Design Team is chartered to first p= roduce a brief gap analysis and requirements document to focus its work on = protocol extensions. This should be published by March 2016. With that basi= s, this Design Team is chartered to rapidly propose extensions to existing = IETF OAM protocols such as those discussed in [RFC 7276] and new ones to su= pport the requirements for OAM from NVO3, BIER, and SFC. The Design Team wi= ll produce an initial proposal by IETF 95. It is expected that the initial = proposal will provide guidance to additional people who will be interested = in working on the details and gaps.

The Design Team will consider th= e preliminary OAM requirements from NVO3, BIER, and SFC. The Design Team sh= ould align with the LIME WG's work on common YANG models of OAM.

The members of the design team are:

=C2=A0 =C2=A0Greg Mir= sky (DT lead)

The design team ha= s a private mailing list that will be publicly archived.

The mail= ing list is rtg-ooam-dt@ietf.org.

The design team will also use a wiki to track s= ome information.=C2=A0 Others are also welcome to comment and interact ther= e.

The wiki is at: =C2=A0 http://wiki.tools.ietf.org/area/rtg/trac/wiki/R= tgOoamDT

Full support and looking forward to working with the DT team! Regards, Jeff On Dec 16, 2015, at 11:33 PM, Alia Atlas > wrote: Based on the presentation by Greg Mirsky and discussion in rtgwg and elsewh= ere, I have decided to charter a fast-moving Routing Area design team to wo= rk on Overlay OAM. The charter is below: In the Routing Area, several WGs (e.g. NVO3, BIER, and SFC) are working on = relatively new encapsulations to create overlays. These overlay or service = encapsulations are transport-independent since they may be over different t= ransports or at different layers in the networking stack. Each WG is starti= ng to discuss what OAM and tools need to be developed (see draft-ietf-sfc-o= am-framework-00, draft-ietf-bier-oam-requirements-00, and individual drafts= in NVO3). With increasing use of overlay and service layer tunnels, extens= ions to traceroute to allow visibility into multiple layers are being discu= ssed (e.g. draft-nordmark-nvo3-transcending-traceroute-01). There is an opportunity to propose protocols and methods to provide Overlay= OAM in a sufficiently generic fashion that they can meet the requirements = and be applied to at least BIER, NSH, VXLAN-GPE, GENEVE, and GUE. A truly s= uccessful result would also be applicable to other technologies. This Design Team is chartered to first produce a brief gap analysis and req= uirements document to focus its work on protocol extensions. This should be= published by March 2016. With that basis, this Design Team is chartered to= rapidly propose extensions to existing IETF OAM protocols such as those di= scussed in [RFC 7276] and new ones to support the requirements for OAM from= NVO3, BIER, and SFC. The Design Team will produce an initial proposal by I= ETF 95. It is expected that the initial proposal will provide guidance to a= dditional people who will be interested in working on the details and gaps. The Design Team will consider the preliminary OAM requirements from NVO3, B= IER, and SFC. The Design Team should align with the LIME WG's work on commo= n YANG models of OAM. The members of the design team are: Greg Mirsky (DT lead) Ignas Bagdonas Erik Nordmark Carlos Pignataro Mach Chen Santosh Pallagatti Deepak Kumarde David Mozes Nagendra Kumar Nainar The design team has a private mailing list that will be publicly archived. The mailing list is rtg-ooam-dt@ietf.org. The design team will also use a wiki to track some information. Others are= also welcome to comment and interact there.

Based on the presentation by Greg Mirsky and discussion in= rtgwg and elsewhere, I have decided to charter a fast-moving Routing Area = design team to work on Overlay OAM.

The charter is below:

In th= e Routing Area, several WGs (e.g. NVO3, BIER, and SFC) are working on relat= ively new encapsulations to create overlays. These overlay or service encap= sulations are transport-independent since they may be over different transports or at different layers in the = networking stack. Each WG is starting to discuss what OAM and tools need to= be developed (see draft-ietf-sfc-oam-framework-00, draft-ietf-bier-oam-req= uirements-00, and individual drafts in NVO3). With increasing use of overlay and service layer tunnels, extens= ions to traceroute to allow visibility into multiple layers are being discu= ssed (e.g. draft-nordmark-nvo3-transcending-traceroute-01).

There is an opportunity to propose protocols and methods to provide Overlay= OAM in a sufficiently generic fashion that they can meet the requirements = and be applied to at least BIER, NSH, VXLAN-GPE, GENEVE, and GUE. A truly s= uccessful result would also be applicable to other technologies.

This Design Team is chartered to first produce a brief gap analysis and req= uirements document to focus its work on protocol extensions. This should be= published by March 2016. With that basis, this Design Team is chartered to= rapidly propose extensions to existing IETF OAM protocols such as those discussed in [RFC 7276] and new ones to s= upport the requirements for OAM from NVO3, BIER, and SFC. The Design Team w= ill produce an initial proposal by IETF 95. It is expected that the initial= proposal will provide guidance to additional people who will be interested in working on the details and = gaps.

The Design Team will consider the preliminary OAM requirements from NVO3, B= IER, and SFC. The Design Team should align with the LIME WG's work on commo= n YANG models of OAM.

The members of the design team are:
Greg Mirsky (DT lead)

Ignas Bagdonas

Erik Nordmark

Carlos Pignataro

Mach Chen

Santosh Pallagatti

Deepak Kumarde

David Mozes

Nagendra Kumar Nainar

The design team has a private mailing list that will be publicly archi= ved.

The mailing list is rtg-ooam-d= t@ietf.org.

The design team will also use a wiki to track some information. = Others are also welcome to comment and interact there.

The wiki is at: http://wiki.tools.ietf.org/area/rtg/trac/wiki/RtgOoamDT=

Alia

Subject: Design Team on Overlay OAM= in Routing is Chartered

Based on the presentation by Greg Mirsky and discussion in= rtgwg and elsewhere, I have decided to charter a fast-moving Routing Area = design team to work on Overlay OAM.

The charter is below:

In th= e Routing Area, several WGs (e.g. NVO3, BIER, and SFC) are working on relat= ively new encapsulations to create overlays. These overlay or service encap= sulations are transport-independent since they may be over different transports or at different layers in the = networking stack. Each WG is starting to discuss what OAM and tools need to= be developed (see draft-ietf-sfc-oam-framework-00, draft-ietf-bier-oam-req= uirements-00, and individual drafts in NVO3). With increasing use of overlay and service layer tunnels, extens= ions to traceroute to allow visibility into multiple layers are being discu= ssed (e.g. draft-nordmark-nvo3-transcending-traceroute-01).

There is an opportunity to propose protocols and methods to provide Overlay= OAM in a sufficiently generic fashion that they can meet the requirements = and be applied to at least BIER, NSH, VXLAN-GPE, GENEVE, and GUE. A truly s= uccessful result would also be applicable to other technologies.

This Design Team is chartered to first produce a brief gap analysis and req= uirements document to focus its work on protocol extensions. This should be= published by March 2016. With that basis, this Design Team is chartered to= rapidly propose extensions to existing IETF OAM protocols such as those discussed in [RFC 7276] and new ones to s= upport the requirements for OAM from NVO3, BIER, and SFC. The Design Team w= ill produce an initial proposal by IETF 95. It is expected that the initial= proposal will provide guidance to additional people who will be interested in working on the details and = gaps.

The Design Team will consider the preliminary OAM requirements from NVO3, B= IER, and SFC. The Design Team should align with the LIME WG's work on commo= n YANG models of OAM.

The members of the design team are:

Greg Mirsky (DT lead)

Ignas Bagdonas

Erik Nordmark

Carlos Pignataro

Mach Chen

Santosh Pallagatti

Deepak Kumarde

David Mozes

Nagendra Kumar Nainar

The design team has a private mailing list that will be publicly archi= ved.

The mailing list is rtg-ooam-d= t@ietf.org.

The design team will also use a wiki to track some information. = Others are also welcome to comment and interact there.

The wiki is at: http://wiki.tools.ietf.org/area/rtg/trac/wiki/RtgOoamDT=

I have no opinion on that, but suggest that an= y OAM work on GRE should be done with GRE/UDP in mind.

Moreover, the GRE/UDP draft is likely to go to= WG Last Call in TSVWG in the next month or so. GRE/UDP is a simple e= ncapsulation, as there is no (shim) header between the UDP and GRE headers, and none will be added (in contrast to the new en= capsulations which have such headers):

Subject: Design Team on Overlay OAM in Routing is Chartered

Based on the presentation b= y Greg Mirsky and discussion in rtgwg and elsewhere, I have decided to char= ter a fast-moving Routing Area design team to work on Overlay OAM.

The charter is below:<= /o:p>

In the Routing Area, several WGs (e.g. NVO3, BIER, and SFC) are working= on relatively new encapsulations to create overlays. These overlay or service encapsulations are transport-independent since they may= be over different transports or at different layers in the networking stac= k. Each WG is starting to discuss what OAM and tools need to be developed (= see draft-ietf-sfc-oam-framework-00, draft-ietf-bier-oam-requirements-00, and individual drafts in NVO3). With = increasing use of overlay and service layer tunnels, extensions to tracerou= te to allow visibility into multiple layers are being discussed (e.g. draft= -nordmark-nvo3-transcending-traceroute-01).

There is an opportunity to propose protocols and methods to provide Overlay= OAM in a sufficiently generic fashion that they can meet the requirements = and be applied to at least BIER, NSH, VXLAN-GPE, GENEVE, and GUE. A truly s= uccessful result would also be applicable to other technologies.

This Design Team is chartered to first produce a brief gap analysis and req= uirements document to focus its work on protocol extensions. This should be= published by March 2016. With that basis, this Design Team is chartered to= rapidly propose extensions to existing IETF OAM protocols such as those discussed in [RFC 7276] and new ones to s= upport the requirements for OAM from NVO3, BIER, and SFC. The Design Team w= ill produce an initial proposal by IETF 95. It is expected that the initial= proposal will provide guidance to additional people who will be interested in working on the details and = gaps.

The Design Team will consider the preliminary OAM requirements from NVO3, B= IER, and SFC. The Design Team should align with the LIME WG's work on commo= n YANG models of OAM.

The members of the design t= eam are:

Greg Mirsky (D= T lead)

Ignas Bagdonas=

Erik Nordmark<= o:p>

Carlos Pignata= ro

Mach Chen=

Santosh Pallag= atti

Deepak Kumarde=

David Mozes

Nagendra Kumar= Nainar

The design team has a priva= te mailing list that will be publicly archived.

The mailing list is rtg-ooam-dt@ietf.org.

The design team will also u= se a wiki to track some information. Others are also welcome to comme= nt and interact there.

The wiki is at: http://wiki.= tools.ietf.org/area/rtg/trac/wiki/RtgOoamDT
