Service providers worldwide are moving toward the dream goal of service automation from the front end of customer ordering and service monitoring to the back end of service provisioning, network monitoring, and active service-level agreement (SLA) enforcement.These are explored in depth with expert opinions. Also explored are a customer self-service portal for on-demand ordering and monitoring of Ethernet services, intelligent customer premises equipment for provisioning and monitoring, and testing and monitoring software for ensuring workability across physical and virtual networks.

Notes de l'éditeur
- Michael/IHS Team – Could you cover a section on market trends in orchestration? This slides includes diagrams from a recent MEF LSO Report and it talks of challenges in moving towards a universal management solution. Option to include or not rests with IHS, of course.

- KulCloud, Omnitron Systems, Veryx, and WebMS partnered to demonstrate Lifecycle Service Orchestration (LSO) at the MEF Proof of Concept Showcase. On a live, multi-vendor network, the partner companies are highlighting the benefits of Lifecycle Service Orchestration for elastic delivery of SLA assured cloud services. The network consists of an SDN-based data center network and a Carrier Ethernet 2.0 access network with 10G protected fiber rings. The Prism SDN controller from KulCloud is used to control the data center network in the demonstration. Service Activation Testing (SAT) and Performance Monitoring are performed for the Layer 3 data center network and the Layer 2 Carrier Ethernet network, using physical and virtual test probes. The network accepts dynamic service requests from end users through a cloud-based, self-service customer portal and then automates the provisioning, remote activation testing and monitoring of the requested service in real time.
- Here is a high-level diagram of a Data Center on the right, that hosts virtual network functions. Enterprise customer has hosted their application at the data center and requires SLA assured on demand service connectivity. Service provider delivers the SLA assured service connectivity from the Data Center network across a Carrier Ethernet 2.0 WAN towards the enterprise. Network Interface Devices, or NIDs, are deployed throughout the CE 2.0 WAN and demarcation points. First Layer 2 demarcation challenge >> SDN/NFV Data center Layer 3 virtual network functions needs to interoperate with the of CE 2.0 Physical Network functions. Example: Preserve or Translate the CoS designators Dynamic service creation and provisioning Bandwidth or capacity upgrade on demand. All of the above have to work in tandem across the Layer 2 and Layer 3 network. >> Second challenge is integrating Performance Monitoring functions for various network layers. The service provider is required to deliver the end-to-end performance monitoring SLA assurance to the Enterprise customer. >> Third challenge How the service provider can seamlessly integrate CE 2.0 Service OAM functions into an already deployed SDN/NFV white box solution without forklift upgrades. >> Fourth challenge, Layer 2 ENNI connectivity is a challenge in a multi operator network. Even more challenging will be connecting multiple service providers and disparate networks. >> Last challenge, Service providers would like to minimize the complex equipment inventory to reduce both CAPEX and OPEX for different types of service tiers across different types of access networks like active Ethernet, xPON, HFC, WDM, etc. Over to you Michael
- Network element based testing is not sufficient Root cause of problem has to be determined Dynamic – transition as VNFs migration
- Network element based testing is not sufficient Root cause of problem has to be determined Dynamic – transition as VNFs migration
- So, the challenge I mentioned before is the interoperability between PNF and VNF >> Demarcation devices should expose and abstract the features and functions to enable ease of programmability from external 3rd party management software. In order to achieve programmability and openness, Demarcation devices must conform to the MEF control plane and data plane specifications for service delivery and enable SDN/NFV within the context of other network developments. Leveraging the definitions, information model and specifications from the MEF are the mechanism by which the new SDN based management can orchestrate and control the CE 2.0 Layer 2 Ethernet services. >> Another challenge is integrating Performance Monitoring functions for various network layers The solution is demarcation devices must support and interoperate with PNF/VNF PM initiator and responder functions for Layer 2 and 3. Not many NID vendors support TWAMP PM for Layer 3 and 4.
- The challenge of adding CE 2.0 functions to SDN/NFV white box solutions without forklift upgrades >> Is accomplished by installing CE2.0 compliant SFP NID into the White Box equipment conserving CPU cores for additional VNFs. Adding CE 2.0 Service OAM with Layer 2 and Layer 3 performance monitoring is a simple as installing a Small Form Pluggable transceiver. >> Seamless ENNI connectivity between different networks is accomplished by deploying NIDs that support CE 2.0 Ethernet Interconnect Points (EIP) standards, MEF 26.1 ENNI port specification and MEF 33/51 defines the access service using MEF 26.1 Technical spec. Demarcation devices must support dual tagging with TPID of 88A8. >> Inventory consolidation challenge is addressed with a single demarcation solution that supports different service tiers like Silver, Gold, and Platinum different service types like Business services, mobile backhaul, small cells and carrier Wi-Fi demarcation with PoE support up to 60W per port. PON, HFC, and Active Ethernet access networks with variety of network functions such as SyncE, Packet timing and security protocols.
- For the Bandwidth on Demand Proof of Concept Omnitron’s iConverter Carrier Ethernet 2.0 Network Interface Devices (NIDs) provided the Physical Network Functions (PNF) for the ring, access, aggregation and demarcation infrastructure. Omnitron devices provided the ENNI connectivity to deliver content delivery services from the SDN/NFV Datacenter to the CE 2.0 WAN and demarcation at the Enterprise. The NIDs responded to Veryx SAMtest controller’s 1564 Service Activation Test initiator at the NOC to perform the service activation testing. The NIDs interoperated with the Veryx Virtual Test Agents (VTA) at the Datacenter and responded to the TWAMP (Layer 3) and Y.1731 (Layer 2) performance monitoring probes non-intrusive to customer data traffic. Upon gathering the customer bandwidth change request via the WebNMS customer webportal the WebNMS Symphony platform managed the Omnitron devices at the Layer 2 CE2.0 WAN network and Enterprise demarcation location by provisioning the appropriate service attributes such as EVC/BWP/CoS and continuously monitored fault and performance of the end to end service.
- The wide area network (WAN) is in the midst of a paradigm shift. Simultaneously, expectations for how bandwidth is delivered are evolving. Omnitron network interface devices have been integrated with many SDN orchestration platforms, and SLA performance monitoring and assurance reporting customer portals. The devices have been tested with various Physical and virtual test assurance platforms. Omnitron has a variety of feature rich CE2.0 standard compliant compact network interface device solutions for various service type and access network deployment. Network Interface Device on a Small Form Pluggable in short NID on a SFP for the SDN/NFV white box solutions adding CE2.0 OAM and wire speed Service Activation Test Initiator and responder capabilities . All of the devices support Performance Monitoring across various network layers Layer 2 Y.1731 Initiator/Responder probes and Layer 3 TWAMP Initiator/Responder probes eliminating the need for expensive standalone test equipments.
