What is NFV?

NFV stands for Network Functions Virtualization. It defines the replacement of usually stand alone appliances used for high and low level network functions, such as firewalls, network address translation, intrusion detection, caching, gateways, accelerators, etc, into virtual instance or set of virtual instances, which are called Virtual Network Functions (VNF). In other words, it could be seen as replacing some of the hardware network appliances with high-performance software taking advantage of high performance para-virtual devices, other acceleration mechanisms, and smart placement of instances. The origin of NFV comes from a working group from the European Telecommunications Standards Institute (ETSI) whose work is the basis of most current implementations. The main consumers of NFV are Service providers (telecommunication providers and the like) who are looking to accelerate the deployment of new network services, and to do that, need to eliminate the constraint of slow renewal cycle of hardware appliances, which do not autoscale and limit their innovation.

NFV support for OpenStack aims to provide the best possible infrastructure for such workloads to be deployed in, while respecting the design principles of a IaaS cloud. In order for VNF to perform correctly in a cloud world, the underlying infrastructure needs to provide a certain number of functionalities which range from scheduling to networking and from orchestration to monitoring capacities. This means that to correctly support NFV use cases in OpenStack, implementations may be required across most, if not all, main OpenStack projects, starting with Neutron and Nova.

Mission statement

The sub-team aims to define the use cases and identify and prioritise the requirements which are needed to run Network Function Virtualization (NFV) workloads on top of OpenStack. This work includes identifying functional gaps, creating blueprints, submitting and reviewing patches to the relevant OpenStack projects and tracking their completion in support of NFV.
The requirements expressed by this group should be made so that each of them have a test case which can be verified using an OpenSource implementation. This is to ensure that tests can be done without any special hardware or proprietary software, which is key for continuous integration tests in the OpenStack gate. If special setups are required which cannot be reproduced on the standard OpenStack gate, the use cases proponent will have to provide a 3rd party CI setup, accessible by OpenStack infra, which will be used to validate developments against.

  • Intensive I/O requirements - potentially millions of small VoIP packets per second per core
  • Intensive memory R/W requirements
  • CDN cache node
  • Router
  • IPSec tunneller
  • Session Border Controller - media relay function
-
Control plane Any other communication between network functions that is not directly related to the end-to-end data communication between edge applications.
  • Less intensive I/O and R/W requirements than data plane, due to lower packets per second
  • More complicated transactions resulting in (potentially) higher CPU load per packet.

ETSI-NFV Use Cases - High Level Description

Use Case #1: Network Functions Virtualisation Infrastructure as a Service

This is a reasonably generic IaaS requirement.

Use Case #2: Virtual Network Function as a Service (VNFaaS)

This primarily targets Customer Premise Equipment (CPE) devices such as access routers, enterprise firewall, WAN optimizers etc. with some Provider Edge devices possible at a later date. ETSI-NFV Performance & portability considerations will apply to deployments that strive to meet high performance and low latency considerations.

Use Case #3: Virtual Network Platform as a Service (VNPaaS)

This is similar to #2 but at the service level. At larger scale and not at the "app" level only.

Use Case #4: VNF Forwarding Graphs

Dynamic connectivity between apps in a "service chain".

Use Case #5: Virtualisation of Mobile Core Network and IMS

Primarily focusing on Evolved Packet Core appliances such as the Mobility Management Entity (MME), Serving Gateway (S-GW), etc. and the IP Multimedia Subsystem (IMS).

Use Case #6: Virtualisation of Mobile base station

Focusing on parts of the Radio Access Network such as eNodeB's, Radio Link Control and Packet Data Convergence Protocol, etc..

Use Case #7: Virtualisation of the Home Environment

Similar to Use Case 2, but with a focus on virtualising residential devices instead of enterprise devices. Covers DHCP, NAT, PPPoE, Firewall devices, etc.

Use Case #8: Virtualisation of CDNs

Content Delivery Networks focusing on video traffic delivery.

Use Case #9: Fixed Access Network Functions Virtualisation

Wireline related access technologies.

Contributed Use Cases

Session Border Controller

Contributed by: Calum Loudon

Description

Perimeta Session Border Controller, Metaswitch Networks. Sits on the edge of a service provider's network and polices SIP and RTP (i.e. VoIP) control and media traffic passing over the access network between end-users and the core network or the trunk network between the core and another SP.

Characteristics

  • Fast and guaranteed performance:
    • Performance in the order of several million VoIP packets (~64-220 bytes depending on codec) per second per core (achievable on COTS hardware).
    • Guarantees provided via SLAs.
  • Fully high availability
    • No single point of failure, service continuity over both software and hardware failures.
  • Elastically scalable
    • NFV orchestrator adds and removes instances in response to network demands.
  • Traffic segregation (ideally)
    • Separate traffic from different customers via VLANs.

Requirements

  • High availability:
    • Requires anti-affinity rules to prevent active/passive being instantiated on same host - already supported, so no gap.
  • Elastic scaling:
    • Readily achievable using existing features - no gap.

Virtual IMS Core

Contributed by: Calum Loudon

Description

Project Clearwater, http://www.projectclearwater.org/. An open source implementation of an IMS core designed to run in the cloud and be massively scalable. It provides SIP-based call control for voice and video as well as SIP-based messaging apps. As an IMS core it provides P/I/S-CSCF function together with a BGCF and an HSS cache, and includes a WebRTC gateway providing interworking between WebRTC & SIP clients.

Characteristics relevant to NFV/OpenStack

  • Mainly a compute application: modest demands on storage and networking.
  • Fully HA, with no SPOFs and service continuity over software and hardware failures; must be able to offer SLAs.
  • Elastically scalable by adding/removing instances under the control of the NFV orchestrator.

Requirements

  • Compute application:
    • OpenStack already provides everything needed; in particular, there are no requirements for an accelerated data plane, nor for core pinning nor NUMA
  • HA:
    • implemented as a series of N+k compute pools; meeting a given SLA requires being able to limit the impact of a single host failure
    • potentially a scheduler gap here: affinity/anti-affinity can be expressed pair-wise between VMs, which is sufficient for a 1:1 active/passive architecture, but an N+k pool needs a concept equivalent to "group anti-affinity" i.e. allowing the NFV orchestrator to assign each VM in a pool to one of X buckets, and requesting OpenStack to ensure no single host failure can affect more than one bucket
    • (there are other approaches which achieve the same end e.g. defining a group where the scheduler ensures every pair of VMs within that group are not instantiated on the same host)
    • for study whether this can be implemented using current scheduler hints
  • Elastic scaling:
    • as for compute requirements there is no gap - OpenStack already provides everything needed.
