1 Área: Lorem ipsum Razón Social: Telefónica CAON Standardization Activities Telefónica I+D Juan Fernandez-Palacios Telefonica I+D. CAON co-chair

2 Área: Lorem ipsum Razón Social: Telefónica  FSAN: Optical access standardization (i.e NGPON2)  IETF: Control plane standardization Key standardization fora

3 Área: Lorem ipsum Razón Social: Telefónica FSAN Task Force  CAON contributions at FSAN are being centralized by Thomas Pfeiffer (ALU)  Key issues  OFDM based NGPON2 solutions are still in an early stage for standardization  Still, in terms of expected total system costs it cannot compete with conventional TDM/WDM-based PON solutions taking into account the current state of component technologies  A solid recommendation to FSAN to choose OFDM technology for NGPON2 solutions can not be done yet

4 Área: Lorem ipsum Razón Social: Telefónica IETF Standardization Task Force TechnologiesIntra-carrierInter-carrier Single DomainMultidomain Packet Switching (IP, MPLS-TP, etc) Wavelength Switching Sub-wavelength Switching IT and network integration (Cross Stratum) MAINS (CCAMP, PCE, MPLS-TP OAM) GEYSERS (CSO)c STRONGEST (PCE, MPLS-TP OAM) ONE, CHRON ETICS (PCE, CCAMP, PCN, CDNI, …), Lots of potential sinergies and collaboration activities within IETF GEYSERS

5 Área: Lorem ipsum Razón Social: Telefónica Innovation challenges in core networks Photonic Transport Transmission ROADM Cost efficient high speed transmission up to 1 Tbps- Flexible Grid. Pure optical subwavelength switching. Multilayer coordination Resource optimization through multilayer planning. OPEX savings from coordinated planes.

6 Área: Lorem ipsum Razón Social: Telefónica Multilayer Interworking  Current core networks are based on several layers.  Mid-term scenario: IP/MPLS network over reconfigurable wavelength switched optical network (WSON).  Three key elements to help in the management and coordination of such multi-layer architectures: User to Network Interface (UNI) Path Computation Element (PCE) Virtual Network Topology Manager (VNTM).  UNI standard method to allow resource request between layers acting as server and client  PCE aim is to calculate the route between endpoints, especially in complex scenarios  VNTM is in charge of maintaining the topology of the upper layer by connections in the lower layer.

7 Área: Lorem ipsum Razón Social: Telefónica Multi-Domain Interworking: H-PCE

8 Área: Lorem ipsum Razón Social: Telefónica Flexgrid Control Plane ITU-T SG-15 is extending the standard G to include the concept of flexible grid › Goal: allow an efficient and flexible allocation and configuration of optical spectral bandwidth for high bit-rate systems. Currenlty ITU-T is extending the architecture of the optical transport networks (G.782) to add the flexi-grid layer (also referred to as the media layer) as the server layer of the optical channels. IETF is starting to look at the definition of the GMPLS based control of the flexible grid networks › Several frameworks and solutions from different companies were presented › In the 84th IETF meeting in Vancouver, the Framework for GMPLS based control of Flexi-grid DWDM networks joining for the first time all the efforts of the industry, led by FP7 STRONGEST partners (Telefonica and CTTC), draft- ogrcetal-ccamp-flexi-grid-fwk-00 was presented. › All the control plane extensions (signalling, routing, path computation) need to be done… still a lot of work ahead…

9 Área: Lorem ipsum Razón Social: Telefónica ITU-T Terminology for Sub-Lambda Photonically Switched Network (SLPSN)  SLPSN definition: SLPSN is a switching technology which handles, at the data plane level and in a photonic way, temporal slices of individual or multiple wavelengths. SLPSN incorporates the optical time domain in addition to the wavelength/frequency and space domains.  SLPSU definition: a sub-lambda photonic switching unit (SLPSU) is an optically sliced unit of a wavelength in time domain, such as an optical time slot, an optical burst, or an optical packet.

Ciulli, “Architecture for Service Provisioning with Cross Stratum Optimization”, Internet-Draft, work in progress, draft-contreras-cso-functional-architecture-00, October 2011  Path Computation Element requirements for CSO A. Tovar, L. Contreras, G. Landi, N. Ciulli, “Path Computation Requirements for Cross-Stratum-Optimization”, Internet-Draft, work in progress, draft- tovar-cso-path-computation-requirements-00, October 2011  An architecture for CSO enabled Path Computation D. Dhody, Y. Lee, N. Ciulli, L. Contreras, O. Gonzalez de Dios, “Cross Stratum Optimization enabled Path Computation”, Internet-Draft, work in progress, draft-dhody-pce-cso-enabled-path-computation-01, March 2012

11 Área: Lorem ipsum Razón Social: Telefónica Conclusions  NGPON2 OFDM is not mature enough for standardization  Multilayer coordination The current standards need to be extended to suggest new configurations (e.g. new TE-Links) to the VNTM. UNI is currently being extended Multilayer PCE, VNTM and UNI can cooperate together.  Multidomain optical networks Hierarchical PCE is a good candidate to enable multi-domain interworking.  Subwavelegths Commom termionolgy is being standardized at ITU-T GMPLS extensions to be proposed at IETF  Flexgrid ITU is standardizing the date plane Frawework has just started in IETF… GMPLS/PCE extensions to be done.  IT and Optical network Convergence First steps taken at IETF
