  1. Carrier Ethernet, SDN and Virtualization Reshaping The Services & Networking Landscape Ralph Santitoro MEF Director and Co-chair of CE4Cloud/SDN Project Director of Strategic Market Development, Fujitsu

  2. Melding of Worlds WAN Connectivity Services • Long service lifecycle • Manual service activation • Infrequent changes Cloud Services • Short service lifecycle • Automated service activation • Frequent changes (Elastic) WAN Connectivity Services Cloud Services On Demand Automated Elastic Services Cloud applications are changing how we view WAN services Carrier Ethernet is evolving to support this new reality

  3. Different objectives but complementary MEF Ethernet Services • Carrier origins • Focus on services • Defines the service Software Defined Networking • Data Center origins • Focus on network architecture • Defines how to build networks MEF Ethernet Services Telecoms World Software Defined Networking IT World MEF Ethernet Services delivered on an SDN SDNs define how networks are implemented Ethernet Services can leverage SDN’s network programmability

  4. MEF Service Attributes Define Network Functions MEF 23.1 CoS Performance Parameters MEF 23.1 CoS Performance Tiers MEF 20 LOAM MEF 10.2 EVC Performance Parameters MEF 6.1 CE-VLAN ID / CoS Preservation • MEF Service Definitions • are agnostic of network or technology implementation • do not specify where network functionality is implemented MEF 30 SOAM-FM MEF 10.2 CE-VLAN ID/EVC Map MEF 7.1 EMS-NMS Info Model MEF 35 SOAM-PM MEF 33 Service Attributes MEF 26.1 OVC BW Profiles MEF 10.2 EVC BW Profiles MEF 26.1 OVC BW Profiles MEF 26.1 ENNI Attributes MEF 26.1 OVC End Point Map MEF 6.1 BUM Frame Delivery • MEF 26.1 • S-VLAN ID / CoS Preservation MEF 10.2 EVC BW Profiles MEF 6.1.1 L2CP Handling MEF 16 E-LMI LOAM MEF 6.1 Service Attributes MEF services accommodate traditional and SDN implementations

  5. MEF work to facilitate Cloud service delivery • Extend services attributes to be more dynamic • E.g., Bandwidth on Demand • Standardized Northbound APIs • Make Ethernet Services more programmable • Enable applications to query Ethernet service attributes, e.g., Bandwidth and Performance • MEF collaborating with ONF • How to map an MEF Ethernet services into an ONF SDN architecture • Need orchestration across multiple operator domains Goal to accommodate traditional and SDN implementations

  6. Summary • Cloud Services have changed how we view Carrier Ethernet services • MEF is evolving Ethernet Service attributes • To better support on-demand cloud service delivery • Supported via traditional or SDN implementations • SDNs with virtualized network functions • may enable new applications or optimize current applications of MEF Ethernet services not possible with traditional network implementations
