communication Protocol (PCEP) for the support of GMPLS control plane. Contributions were brought to the IETF draft draft-ietf-pce-gmpls-pcep-extensions-01
• PCEP Extensions for Temporary Reservation. The contribution proposes an extension to the PCEP protocol to allow the PCC to request the PCE to block or reserve the resources computed in a path request of a TE LSP for subsequent requests for a certain time.

Extensions to Path Computation Element Communication Protocol (PCEP) for Hierarchical Path Computation Elements (PCE). This
document defines the Path Computation Element Protocol (PCEP) extensions for the purpose of implementing hierarchical PCE
procedures which are described in [PCE-HIERARCHY-FWK]. Relevant draft draft-zhang-pce-hierarchy-extensions-00
Methods and extensions / standard way to represent domain sequences in various deployment scenarios, including P2P, P2MP and
HPCE, involved draft: draft-dhody-pce-pcep-domain-sequence-01
Some of these contributions are still at early stages, potentially being merged, replaced, etc. Also, note that the PCE WG re-chartered a
few weeks ago, so it is expected that some of the individual drafts will be proposed / adopted as working group items (e.g. the poll for
adoption of draft-zhao-pce-pcep-inter-domain-p2mp-procedures-06 closed recently)
Finally, testing in the scope of WP3 and WP4 identified problems regarding PCEP transport (TCP ports) which have been addressed as
erratas to RFC5440 (main PCEP RFC) regarding, notably port restrictions
.
STRONGEST standardization interests in IETF in details
Área: Lorem ipsumRazón Social: Telefónica
Project name: STRONGEST
Main topics of interest on standardization: resource and admission control, energy efficiency
Targeted standardization fora: ETSI
Standardization status: • A first contact with ETSI TISPAN has been made, and it is intended to present STRONGEST there in the
next year. Once a suitable RACS extension has been defined within STRONGEST, it is planned to contribute it to TISPAN.
• A first presentation of the STRONGEST project and its goals has been made to ETSI EE, and a liaison exchange has been started in order to gain access to latest ETSI work and to inform EE about positions and developments at STRONGEST. It is expected that STRONGEST extensions to the metric will be contributed to ETSI EE once the work has sufficiently progressed.

Standardization in SARDANA
SARDANA project targets a practical transparent approach to Access&Metro Convergence.
Presence and contribution to FSAN mainly:
• Optically converged Hybrid Ring-Tree WDM-TDM Metro-Access Architecture
› Passive Ring-Tree Interface (Remote Node)
• Multi-operability, scalability and transparency.
List of FSAN meeting attended :• Japan – Kyoto, Lake Biwako November 2009
• USA – San Francisco February 2010
• China – Beijing April 2010
• Europe - Munich - September 2010
• USA – Las Vegas – November 2010
• Japan – Tokyo – January 2011
Three persons of SARDANA project were participating at FSAN meetings, from FT-Orange, IT and ISCOM.
Área: Lorem ipsumRazón Social: Telefónica
Standardization activities
• Poster about SARDANA during 2009 Kyoto meeting (and to ECOC’09)
• a presentation on "Interest in NGPON2 at FT" with the Sardana solution, (Kyoto)
• Call For Contribution on extended reach and topics for NG-PON2 workshop as Wavelength Stacking, Central
Office Consolidation, Achievable Optical Budget projections.
• White Paper on the drivers, requirements, and technologic evolutions for NG-PON2 : introducing the
concept of SARDANA ring-tree solutions.
• Several publications in Sardana (ECOC'09, ICTON’10) describe and specify key Sardana elements (like the ring-tree Remote Node) in terms
of Standardization, as proposals for NGPON2.
• In every Sardana plenary meeting, the FT, IT and ISCOM partners, that attended these Standardization meetings, updated the Sardana partner
representatives (with the required confidentiality) with the latest recommendations, so the designs have been aligned at every time as
much as possible.
