Wiki Updates May 2015

The following are proposed updates for Industry impact section in NFV, the TiS section in Wind River Systems and the addition to the Overview section in Open vSwitch.

The purpose is to update NFV-related articles to include current TiS information on availability (fault tolerance) and performance (AVS), drawing on recent news releases and Ton Nolle's blog.


Industry impact

NFV has proven a popular standard even in its infancy. Its immediate applications are numerous, such as virtualization of Mobile base stations, Platform as a Service (PaaS), Content Delivery Networks (CDN), fixed access and home environments.[3] The potential benefits of NFV is anticipated to be significant. Virtualization of network functions deployed on general purpose standardized hardware is expected to reduce capital and operational expenditures, and service and product introduction times.[4][5] Many major network equipment vendors have announced support for NFV.[6] This has coincided with NFV announcements from major software suppliers who provide the NFV platforms used by equipment suppliers to build their NFV products.[7][8]

However, to realize the anticipated benefits of virtualization, network equipment vendors are improving IT virtualization technology to incorporate carrier-grade attributes which are required to achieve high availability, scalability and performance, and effective network management capabilities.[9] To minimize the total cost of ownership (TCO), carrier-grade features must be implemented as efficiently as possible. This requires that NFV solutions make efficient use of redundant resources to achieve five-nines availability (99.999%)[10], and of computing resource without compromising performance predictability.

The NFV platform is the foundation for achieving efficient carrier-grade NFV solutions.[11] It is a software platform running on standard multi-core hardware and built using open source software that incorporates carrier-grade features. The NFV platform software is responsible for dynamically re-assigning VNFs due to failures and changes in traffic load, and therefore plays an important role in achieving high availability. There are numerous initiatives underway to specify, align and promote NFV carrier-grade capabilities such as ETSI NFV Proof of Concept[12], ATIS[13] Open Platform for NFV Project,[14] Carrier Network Virtualization Awards[15] and various supplier ecosystems.[16]

The vSwitch, a key component of NFV platforms, is responsible for providing VM-to-VM (virtual machine) and VM to the outside network. Its performance determines both the bandwidth of the VNFs and the cost-efficiency of NFV solutions. The standard Open vSwitch's (OVS) performance has its shortcomings which need to be resolved to meet the needs of NFVI solutions.[17] Significant performance improvements are being reported by NFV suppliers for both OVS and Accelerated Open vSwitch (AVS) versions.[18][19] The level of improvement is critical to the CSP business as it directly translates to lower Total Cost of Ownership TCO. For example a seven fold improvement using an Accelerated vSwitch (AVS) would result in an NFV solution requiring just 15% as many blades as a standard OVS-based solution.[20]

Virtualization is also changing the way availability is specified, measured and achieved in NFV solutions. As VNFs replace traditional function-dedicated equipment, there is a shift from equipment-based availability to a service-based, end-to-end, layered approach.[21][22] Virtualizing network functions breaks the explicit coupling with specific equipment, therefore availability is defined by the availability of VNF services. Because NFV technology can virtualize a wide range of network function types, each with their own service availability expectations, NFV platforms should support a wide range of fault tolerance options. This flexibility enables CSPs to optimize their NFV solutions to meet any VNF availability requirement.

Wind River Titanium Server

Introduced in 2014, the Wind River Titanium Server provides a Network Functions Virtualization (NFV) software platform used by network equipment suppliers to build NFV equipment.[23] The product is based on Wind River Open Virtualization and includes Wind River Linux, an optimized real-time Kernel-Based Virtual Machine (KVM++), Intel Data Plane Development Kit (Intel DPDK), Accelerated vSwitch (AVS) technologies and carrier grade extensions and plug-ins to OpenStack. The server provides the following basic capabilities:[24][25][26]

  • Fault Tolerant: capable of being configured to achieve a range of service availability requirements, including “six 9s” availability which is achieved by carrier-grade fault management features and reliable software.
  • Performance: carrier-grade Accelerated vSwitch (AVS), responsible for providing the VM-to-VM (virtual machine) and VM to the outside network, achieves high and efficient network performance and scalability to maximize the number of subscribers per server. The Accelerated vSwitch (AVS) achieves a 20 fold improvement in performance.[27]
  • Manageability: scheduling and orchestration of workloads, failures, and security to management service level agreements (SLAs). The platform manages applications through existing OSS/BSS/NMS systems and uses standards-based application programming interfaces (APIs)

Open vSwitch Overview (addition only)

The market success of Open vSwitch depends not just on its ease of programmability, but OVS needs to be fast and efficent. The standard version's performance shortcomings, such as high overhead, need to be resolved to significantly improve throughput - and do so by the efficient use of computing resources and without compromising performance predictability.[28] With the advent of Network Functions Virtualization (NFV) there have been a number of initiatives to accelerate OVS performance. Improvements have been reported of 10 to 20 times for both OVS and Accelerated vSwitch (AVS) versions over the standard OVS configuration.[29][30]
