‘we make data make money’
Our real time telecom business support
systems enable the commercialization of
operator's network activity
• Leading global provider of virtualized, highly
scalable, ultrahigh performance, real-time
mediation, charging and policy systems
• Deployed globally in mission critical applications
including 3 of 4 US Tier 1 Telcos covering 85% of all
NAR subscribers
• Differentiated through performance, in-service
experience and support
• Incumbent position in rapidly emerging NFV and
VoLTE roll-outs

5. 5© Copyright 2017 Openet Classification: Confidential
®
• In 2012 Openet deployed the world’s first virtualized vPCRF across
a large tier one operator
• This included large scale deployments e.g. of 13 datacenters and
over 600 hypervisors
• This was pre-NFV but the solution consisted of a number of similar
components:
• Orchestration workflows
• Configuration Master
• Virtual infrastructure manager (RHEV-Manager)

Current Telco Challenges

9. 9© Copyright 2017 Openet Classification: Confidential
• Traditional voice, SMS and new IP services
are steadily being gobbled up by OTTs
• Deliver ‘apps’ that people want, at
incredible speeds and at low cost.
• DevOps mentality encourages rapid
innovation and deployment of new
services.
• If services fail, they learn and quickly move
to next big thing.
Current Telco Challenges

They must behave like Google
• To date Operator’s network flexibility has been limited to automating specific tasks.
• Tasks which were never tightly coupled to overall business process or strategy.
Launch & iterate, fail fast and fail often

What is NFV?

13. 13© Copyright 2017 Openet Classification: Confidential
What is NFV?

14. 14© Copyright 2017 Openet Classification: Confidential
NFV Reference Architecture
• VNF: Virtual Network Function – S/W implementation of network
function like P-GW, DPI or PCRF
• VNFM: VNF Manager manages life cycle of VNF ( creates, maintains
and terminates VNF instances).
• EMS: Element Manager Fault, Configuration, Accounting,
Performance and Security Management (FCAPS )
• NFVI: H/W and S/W environment in which VNFs deploy
• VIM: Virtualised Infrastructure Manager controls NFV resource (e.g.
Openstack, VMWare)
• Orchestrator: Service level lifecycle management. Orchestration of
physical and/or software resources that support the infrastructure
virtualization, and the lifecycle management of VNFs.

What is MANO?

16. 16© Copyright 2017 Openet Classification: Confidential
MANO and Openet
• MANO stands for Management and Orchestration.
• Virtualized Infrastructure Manager (VIM).
• Manages NFV resources that includes physical (server,
storage etc.), virtual resources (Virtual Machines) and
software resources (hypervisor) in an NFV
environment.
• VNF Manager (VNFM).
• This is the VNF Manager, which manages life cycle of
VNFs. That is it creates, maintains and terminates VNF
instances.
• NFV Orchestrator (VNFO).
• Automated arrangement, coordination, and
management of complex computer systems

Vendor Onboarding into MANO

19. 19© Copyright 2017 Openet Classification: Confidential
• Topology and Orchestration Specification for Cloud Applications (TOSCA), is an OASIS standard language to
describe a topology of cloud applications
• Capture everything needed to run the application
• Benefits include:
• Interoperability
• Portability
• Multi VIM
• Topology, workflows, policies
What is TOSCA?

20. 20© Copyright 2017 Openet Classification: Confidential
• Topology
• Defines nodes, relationships, capabilities
• Workflows
• Lifecycle Operations – install, scale etc
• Policies
• can express such diverse things like monitoring behavior, payment conditions, scalability, or continuous availability, for
example.
Topology, workflows, policies

21. 21© Copyright 2017 Openet Classification: Confidential
• They have a similar structure
• Description
• Input Parameters
• Output Parameters
• They have some differences
• Support for Workflows
• The WF is hardcoded into heat engine
• TOSCA has no hard coded processes

SR-IOV
• Single Root I/O Virtualisation provides :-
• Direct I/O throughput
• Reduced CPU utilization
• Increased scalability
• Improved device performance for
virtual guests

26. 26© Copyright 2017 Openet Classification: Confidential
SR-IOV
• In traditional I/O architectures, a single core has to
• handle all the Ethernet interrupts for all the incoming packets
• and deliver them to the different virtual machines running on the
server.
• Two core interrupts are required
• one to service the interrupt on the NIC (incoming packet) and
determine which VM the packet belongs to
• the second on the core assigned to the VM, to copy the packet to the
VM where the packet is destined.
• SR-IOV introduces the idea of a Virtual Function (VF).
• Virtual Functions are ‘lightweight’ PCI function entities that contain
the resources necessary for data movement.
• The hypervisor is not involved in the packet processing to move the
packet (between the hardware interface and the actual VM) thus
removing any bottlenecks in the path.

27. 27© Copyright 2017 Openet Classification: Confidential
DPDK
• Intel® Data Plane Development Kit (Intel® DPDK), a set of software libraries that can improve
packet processing performance by up to ten times.
• It moves control of Ethernet hardware directly into userspace processes to avoid the overhead of
communicating with the operating system kernel.
• This gives userspace all of the raw performance traditionally enjoyed by the kernel – and all of the
responsibility too.
• This is important for specialized low latency applications such as virtual network functions.
