Thanks for the work on this. It's looking good.

Subject: [CCAMP] Charter update


Hi working group,


as briefly anticipated during the CCAMP session at IETF110 please find below
the proposal for the update to the charter. 

Please send you comments/suggestions before April 15th.



Daniele , Fatai, Oscar



The CCAMP working group is responsible for standardizing a common control
plane and a separate common measurement plane for non-packet technologies
found in the Internet and in the networks of telecom service providers (ISPs
and SPs). Examples of the devices in such networks include photonic
cross-connects, OEO switches, ROADMs, TDM switches, microwave links, and
Ethernet switches.

In this context, measurement refers to the acquisition and distribution of
attributes relevant to the setting up of tunnels and paths.

The working group develops extensions to core Traffic Engineering protocols
that are under the care of other working groups as well as YANG models for
the control and management of non-packet networks (this includes both device
models and network models). The CCAMP working group will coordinate with the
TEAS working group to ensure that extensions that can be generalized for use
with more than one technology are made appropriately, and with the working
groups that have responsibility for the specific protocols.


CCAMP WG work scope includes:

*	Definition of protocol-independent metrics and parameters
(measurement attributes) for describing links and paths that are required
for routing and signaling in technology-specific networks. These will be
developed in conjunction with requests and requirements from other WGs to
ensure overall usefulness.
*	Maintenance and extension of the Link Management Protocol (LMP)
*	Functional specification of extensions for GMPLS-related routing
(OSPF, ISIS) and signaling (RSVP-TE) protocols required for path
establishment and maintenance in non-packet, technology-specific  networks.
Protocol formats and procedures that embody these   extensions will be done
jointly with the WGs supervising those  protocols and the TEAS working group
has the responsibility to   determine whether such protocol extensions
should be generalized  for Traffic Engineering in any network. This may
include protocol work to support data planes that have  already been
approved by another Standards Development Organization. Note that the
specification or modification of data  planes is out of scope of this
working group.
*	Definition of management objects (e.g., as part of MIB modules or
YANG models) and control of OAM techniques relevant to the  protocols and
extensions specified within the WG. The OAM work will be synchronized with
*	Describe non-packet-specific aspects of traffic engineering
including for multi-areas/multi-AS/multi-layer scenarios and  define
protocol extensions in cooperation with the TEAS and  PCE working groups.
*	Define how the properties of network resources gathered by a
measurement protocol (or by other means such as configuration) can be
distributed in existing routing protocols, such as OSPF,  IS-IS, and BGP-LS.
CCAMP will work with the WGs that supervise  these.

The CCAMP WG currently works on the following tasks:

*	Protocol extensions and YANG models in support of optical networks
(e.g. WSON, flexi grid) with and without awareness of the optical

- Protocol extensions in support of flexible grid lambda networks.

*	Protocol extensions and YANG models in support of TDM networks (e.g.
*	YANG models in support of microwave networks.
*	YANG models fin support of L1 services
*	Client TE topologies 
*	Maintenance of existing protocol extensions for non-packet
technology-specific networks (Ethernet, TDM, OTN) already specified by
*	Maintenance of LMP.
