In July 2015, IHS Infonetics, a world-renowned consulting firm, released the latest market research report on NFV (Network Functions virtualization, networking function virtualization). The report shows that the NFV market space will grow from $950 million in 2014 to $11.6 billion in 2019, with a CAGR of 65% and a gradual shift in value from hardware to software, with software accounting for 80%, suggesting that the era of NFV has come full-fledged.

At the same time, the global LTE construction is fully rolled out, operators have also accelerated volte (Voice over LTE) construction, Vodafone, Deutsche Telekom, T, China Mobile, Hong Kong Telecom, Skt and LG Uplus have launched the commercial VoLTE network, It is expected that at the end of 2015 there will be 460 LTE networks and more than 100 million volte users, more than half of which will be built with NFV technology.

NFV develops into the fast lane, the core network will be the first cloud

In October 2012, NFV-ISG was established by 13 leading operators in ETSI to promote "network function virtualization", launched the NFV white Paper, and proposed the NFV objectives and action plan, which aims to decouple the software and hardware of traditional telecommunications equipment, based on common computing, Storage and networking devices enable telecom network functions, improve management and maintenance efficiency, and enhance system flexibility.

After more than 3 years of development, NFV technology has become increasingly mature, into the rapid development period, standards organizations, open source organizations, operators and equipment vendors to work together to promote the development of the NFV industry chain. According to the IHS Infonetics Survey, 35% of operators will deploy NFV in 2015, and the world's leading operators have launched their own network transformation strategy based on NFV and SDN technology.

For example, at/T launches the Domain 2.0 initiative to transform the network infrastructure from hardware-centric to software-centric, open-cloud-based networks, restructure operators, and open network capabilities, with the goal of achieving 75% network virtualization by 2020.

Telefonica launches the UNICA project to build a distributed, unified, and easy-to-control cloud data center based on the SDN network and telecom Services cloud deployment to meet the demands of agile deployment, on-demand, and easy-to-control for telecommunications and general cloud services.

China Mobile in the 2015 Shanghai World Mobile Congress, the official release of the Novonet 2020 Vision, the hope to integrate new technologies such as NFV and SDN, to build a resource can be globally scheduled, the ability to fully open, capacity resilient scalability, and the architecture can be flexibly adjusted next generation network.

Operators have fully recognized the importance of NFV to future network evolution, which has been listed as the cornerstone of future network strategy development. The industry has also reached two common understandings for the development of NFV: first, the development of NFV will begin with the core network, first the control plane, then the signaling surface and the data plane, and finally the media surface; second, NFV is not just a reduction in operating costs, but an agile, valuable and intelligent cloud network based on NFV, That leads to more revenue growth, the real business value of NFV.

Huawei Cloudcore leads the way of core network cloud

Core network as a telecommunications network exchange and control center, after the cloud needs to continue to maintain high reliability, high performance, fault self-healing and queue flow control, such as carrier-class service level requirements, but also have an open architecture capability, which must require the core network has a truly cloud-oriented software design.

The Huawei Cloudcore Solution incorporates a leading cloud-based software architecture design, including Vims (IP multimedia Subsystem), VSDM (subscriber Data Management), Vdra (Diameter Routing Agent), VPCRF (Policy and charging Rules Function), and VSBC (Session Border Controller), a full range of core cloud products, And the new Mano (Management and Orchestration) section, and can be easily opened to third-party applications based on a fully cloud-capable core network.

An Agile core network

The agility of the network is the primary function that operators bring to the NFV/SDN evolution, which integrates the resource elasticity of infrastructure cloud, the network elasticity of SDN, and the business elasticity of NFV, according to the business demand, the network, VNF (virtualized function, virtual network capabilities, and cloud infrastructure to enable it to automatically increase business instances as the business grows, and to automatically reduce business instances as the business slows down, enabling automated, end-to-end deployment and flexible scheduling of the entire system's resources to accelerate business uptime.

Network function virtualization is expected to save more than 70% of hardware and more than 40% of opex (operation expenditure) operating costs with COTS (commercial off-the-shelf) universal servers, And all of this has to be built on software refactoring to support cloud-based features.

Huawei Cloudcore Solutions adopt advanced Cloud Software Architecture, support program and data separation, business processing unit without call state data, store business state in separate distributed database, so that business processing unit can flexibly scale, Can flexibly increase or release the occupied virtual machine resources according to the increment of business volume, and the current session in the scaling process will not suffer any loss. In addition, the core network as the backbone of the communication network, carrier-class service level guarantee is indispensable. The Huawei Cloudcore solution is based on multi-layered reliability strategies, health detection and fault self-healing based on business KPIs, latency-based business queue flow control, and high performance design with virtual compute/storage/network resource optimization. and heterogeneous resource pool and other technological innovations ensure that network virtualization remains more than 99.999% of carrier-class reliability.

Not only that, Huawei's Cloudcore solution architecture is fully open to support a wide range of common hardware and cloud operating systems, as well as the ability to integrate with multiple vendors.

"Case sharing"

At the beginning of July 2015, Huawei helped Vodafone to formally commercial the world's first cloud volte network in its Italian subnet, becoming a milestone in the transformation of the telecommunications cloud, and its successful experience has attracted wide attention from the industry. In this project, Huawei is responsible for providing mature cloud IMS and providing end-to-end horizontal and vertical integration services as the primary integrator, which guarantees the carrier-class capability of the cloud network.

A valuable core network

In the face of OTT players competing, the business innovation ability is not enough, it is difficult to play its advantage in the network pipeline, it is difficult to compete with OTT players in the business and user experience. The advent of NFV/SDN technology enables operators to easily and flexibly integrate their plumbing capabilities, leveraging technologies such as big Data, NFV and SDN to open their capabilities to third parties, creating a new ecosystem and increasing the revenues of their operators.

Huawei Cloudcore Solutions enable operators to provide a one-stop network capability open platform for third-party partners, including DevOps (development and operation) integrated operational models that include development, testing, on-line, and operations-wide lifecycle Encapsulation of communication resources such as voice, video, conferencing, messaging, location, bandwidth, and data of the carrier into an API (application programming Interface) or SDK (software development Kit), open to partners, To accelerate the new business innovation and on-line, to achieve the operator and partner win.

In addition, operators can use network function virtualization to directly open their network capabilities to third parties to provide services, namely VNF as a service. For example, operators can unify the media surface, combine control surfaces and open capabilities to provide ubiquitous real-time audio and video and streaming services, including audio and video transcoding, audio and video optimization and audio and video analysis capabilities to meet the needs of individual, family, business and industry different commercial scenarios.

The existing telecommunications network can not fully meet the needs of various industries for telecommunications capabilities, for example, the car network needs ultra-low latency, video sites need high-bandwidth capabilities, and banking business needs very high network reliability. The advent of NFV/SDN technology has made it possible to establish a virtual private network for each enterprise or industry, and we can visually call it a network shard--cutting the traditional telecommunications network into thousands of network shards, each of which corresponds to a business or industry customer, The service provided by the operator can be referred to as a network Shard service (Slice).

"Case sharing" Sichuan mobile in the face of industry and OTT severe competition in the situation, the adoption of Huawei Cloudcore capability open Platform for enterprises, developers and OTT open multimedia calls, multimedia conferencing and multimedia messaging and other rich communication capabilities, together to build enterprise and industry applications, the user from people to the mobile phone , set-top boxes, cameras, and the internet of things. Among them, an OTT micro-business through the call Sichuan Mobile communication capabilities to provide instant communication services, business online six months has been accumulated to Sichuan mobile to bring more than 200 million minutes of the traffic volume, the daily call can reach 1 million minutes. In addition, the platform's resiliency and intelligent operation capabilities based on NFV technology also enable Sichuan Mobile to easily respond to explosive third-party business growth, creating an industry model for both operators and OTT.

An intelligent core network

Network virtualization based on data center, decoupling of network hardware and software, network personalization, introduction of massive third-party business, and automatic orchestration and elasticity of business and resources all require that the whole network must have the features of maintainability, service and operation.

Based on the pooling of infrastructure and full capacity openness, Huawei Cloudcore Solutions can unify and unify the network, resources and network elements according to different business and strategy, and automatically integrate and integrate operational experience to realize automatic orchestration and operation and automation of business through unified intelligent Orchestration System. Reduces the workload and reduces maintenance complexity.

KPI-based health detection and fault self-healing is also an important means to ensure the service level of the system carrier. Huawei Cloudcore Solution supports real-time monitoring of business KPIs and compares them with historical statistics, and after the key business KPI falls to a certain range, it starts automatic alarm, automatic switching and other measures to realize the self-healing of the system fault.

The Huawei Cloudcore solution also supports end-to-end fault-bound positioning after network hardware and software decoupling, and intelligently analyzes and correlates the security information of each component, such as logs, alarms, and abnormal output, to quickly locate or predict the security potential of the system in advance. In addition, the Business processing unit under the cloud architecture has no call state data and supports N+m backup mode, which greatly improves the reliability of the whole system and reduces the urgency and cost of maintenance.

"Case sharing"

As a premier integrator, Huawei is helping Vodafone to provide a range of end-to-end operational tools as it formally commercialized the world's first cloud volte network in its Italian subnet. The two sides in the Huawei Nfv/sdn Open Laboratory for Joint Innovation Verification, and cooperative development of health detection tools, in a fully mirrored Vodafone Italy in the environment of artificial injection failure, the experiment proves that: the system according to the expected realization of sub-health automatic detection and system self-healing, The fault location, which takes more than 4 hours, is converted into a 3-hour early warning to avoid the occurrence of the fault.

NFV will be the enabling technology for future fully connected networks

Huawei predicts that by 2025, the world will have 100 billion connections, 6.5 billion internet users, 8 billion smartphones, which indicates that we are entering a fully connected world. Connectivity-based ICT technologies, such as cloud computing, 5G, and the Internet of things, are leveraging the world's sustainable leverage, and the cool, immersive business experience of virtual reality, augmented reality, holographic communications and immersive communications will be a reality.

The fully connected world requires a comprehensive reconfiguration of the communication network, and NFV will be the enabling technology for network reconfiguration, architecture refactoring, operational refactoring, and business reconfiguration. Regardless of how the network changes, its core function still depends on the connection control, data management and policy management, but need to have higher requirements to meet the needs of mass terminal and mass business, such as ultra-high bandwidth, ultra-low latency, big data, context-based policy control, network fragmentation and hierarchical distributed deployment and so on.

Huawei Cloudcore Solutions lead the core network transformation, and actively engage with the world's leading operators to carry out a fully connected core network research. At the same time, Huawei also plays an important role in the standard and open source communities associated with NFV, the co-chair of the NFV infrastructure group in the ETSI NFV Standards Organization, which has been adopted at the top of 1153 proposals.

In addition, Huawei was once again awarded the "Best Cloud IMS Solution" award at the 2015 IMS World Forum. Huawei also partnered with partners to drive the development of the NFV industry through the opening of NFV/SDN labs in Asia, Europe and North America, and became one of the OPNFV's 9 accredited laboratories worldwide.
