1 Slide title In CAPITALS 50 pt Slide subtitle 32 pt GMPLS RSVP-TE Extensions for OTN and SONET/SDH OAM Configuration draft-kern-ccamp-rsvp-te-sdh-otn-oam-ext-00 András Kern – Ericsson Attila Takács – Ericsson IETF-75 Stockholm

2 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Background, motivation, objectives SONET/SDH and OTN support a rich set of supervision functions [ITU-T G.806] –Continuity/Connectivity/Signal quality/Payload Type/Multiplex structure/Alignment supervision –Management signals Configuration of supervision functions requires extensive management steps executed separately from connection establishment signaling Extend connection establishment for SONET/SDH [RFC4606] and OTN [RFC4328] with the configuration of supervision functions in GMPLS controlled networks Extension is based on the OAM Configuration framework for GMPLS: draft-ietf-ccamp-oam-configuration-fwk

3 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Supervision functions in scope: –Continuity –Connectivity –Signal Quality Two new technology specific OAM Configuration TLVs carried in the LSP_ATTRIBUTES Object OTN OAM Configuration TLV OTN TTI Configuration Sub-TLV SAPI and DAPI (forming TTI) Match on SAPI, DAPI, SAPI+DAPI Unidirectional/upstream/downstream/both AIS insertion OAM Configuration Extensions Degraded signal thresholds Sub-TLV Error model: Bursty Threshold parameters for Degraded Signal SONET/SDH OAM Configuration TLV SDH TTI Configuration Sub-TLV Trail trace identifier (TTI) Upstream/downstream AIS insertion Degraded signal thresholds Sub-TLV Error model: Poisson/Bursty Threshold parameters for Excessive Error/Degraded Signal

4 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt OAM configuration of FA-LSPs RFC4328 defines bi-region model for OTN –Digital (ODUk) LSPs [TDM] –Optical (OCh) LSPs [LSC] Currently no OAM for Optical OCh LSPs OTUk digital layer is used to create a managed optical connection adding OAM functions Optical LSPs provide FAs for the digital hierarchy –Signaling of FA-LSPs according to RFC 4206 and draft-ietf-ccamp-lsp- hierarchy-bis Proposed extension –Configure OTUk supervision functions along with server optical LSP utilizing FA-LSP signaling –OAM Configuration TLV for the OTUk layer added to the LSP_TUNNEL_INTERFACE_ID Object –Default values for OAM related flags that would be carried in the Attribute Flags TLV MEP desired – YES MIP desired – NO AIS desired – YES OTUk OCh

5 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Next Steps Solicit feedback and comments from the WG This draft is complementing draft-ietf-ccamp-oam- configuration-fwk by defining technology specific objects and mechanisms Adopt as WG document
