Virtualization to simplify and fully meet the future of Internet and cloud computing environment needs

The need for the web has spawned NFV (receptacle function virtualization, network functionality virtualization), and in recent days, this concept is driving the development of communications services, which have been adopted by a large number of telecom operators, or are attempting to use the NFV scheme, To build a safe and efficient network. Among the many solutions suppliers in the market, the Wind River is absolutely unique, this Intel's wholly owned subsidiary, in the field of telecommunications for many years, in fact, the operating system (RTOS) has been in the industry to maintain a "fact standard" status, then, in the NFV tide, How can the Wind River's solution help telecom operators?

The NFV in fact, the telecom operators for the NFV demand is not out of thin air, but the network transformation to pull. The basic need for network communication is always the desire for bandwidth, and the elimination of security concerns, while taking into account the cost costs. In a word, it is to solve the problem of performance and security under the condition of limited cost resources. The breakthrough to solve this problem is intelligent, so that operators of the network more intelligent.

Any system that is intelligent and low-cost will be implemented through standardized hardware plus powerful software, which is a universally accepted trend. In a more intelligent way, give full play to the standardization of hardware advances brought about by the potential and advantages of the Wind river such software manufacturers is an unprecedented opportunity. For operators, it can be purchased at low prices to a large number of standardized general-purpose hardware platform, deployed in a wider range, and what these hardware devices are doing, but can be based on the needs of this place, through the software to flexibly configure.

Especially in the future, due to the use of Industrial standard server hardware, performance and capacity upgrades are very convenient. In terms of functional diversity, if you need to add more value-added features or upgrade requirements, it is also easy to achieve through software upgrades, do not need to replace the hardware. In this context, the Wind River has become the preferred choice of NFV solutions for operators to consider.

The Wind River's NFV business-to-business purchases are clearly rational, and despite the advantages of the Wind river, operators will still be cautious about their purchases, and all concerns will vanish once they have a real understanding of the NFV solution to the Wind River. Many manufacturers in the industry are also launching NFV, the key is to see what kind of technology is based on. The characteristics of the Wind River is based on embedded software technology. And only on this basis, to reach the carrier level.

Compared with the enterprise IT software technology used by traditional It data centers, carrier-level NFV software lowers the price by one-fifth, improves performance by five times times, and achieves 6 9 levels of availability.

To achieve this goal, the Wind River employs HP's Intel architecture based cots server, and the Wind River breaks through the embedded realm, enabling its software to run on general-purpose industrial standard x86 servers.

At present, many providers of solutions claim to be able to offer NFV solutions, but if they cannot deliver carrier-level capabilities, they are not truly NFV products. And operator-level performance has been a part of the Wind River Company's DNA.

As a mandatory requirement of the telecommunications industry, operator-level performance is essential for operators and service providers, and the Wind River provides the River Carrier Grade Communications server solution that enables:

-Maintain the availability of the existing 5 9 or 6 9 levels (99.999至99.9999%) to ensure that downtime does not exceed 30 seconds per year.

-Manage applications through existing OSS/BSS/NMS systems.

-Provide a high level of scalability, in particular by adding new equipment to the network as part of the Internet of things.

-Achieve the performance and security requirements of the service level agreements (Sla,service levels Agreement) that have been implemented for users through the original virtualization application.

Traditionally, it and telecommunications communications are two different areas and industries. It networks are developed to deliver data. Telecommunications networks are developed to deliver voice. The fundamental difference between data and voice is that the voice is a continuous signal, uninterrupted, not delay, and the data is independent of discrete signals, can be segmented and based on the channel's free and busy status to adjust the transmission time.

In the IT field, the concept of "virtualization" comes together from the day the computer was invented. In order to solve the problem of sharing and utilization of all kinds of resources such as processor, memory and peripherals, various virtualization theories, methods and techniques have been developed in computer system. The core of virtualization technology is to virtualize less resources with faster processing speed, making users feel like they have more or even unlimited resources. Obviously, this is more or less the possibility of dispensing, it is not hundred percent reliable, and this is tolerable for data transmission. Hu Xueyan said "the eight jars Seven cover, cover to cover to go without help, this is business", a good interpretation of the concept of virtualization.

In the field of communications, the fundamental aim is to solve the problem of communication and signal transmission between two telephones and telegraph, whether using a landline line or using a radio channel, assuming that the communication channel is exclusive. The traditional telephone switchboard is continuously connected during the two telephone calls until the end of the call is disconnected. So, as long as the two sides can talk, the line is hundred cent belong to them. When you make a phone call, it's a very painful thing to do if the line breaks down or is slightly delayed. Therefore, the telecommunications operators require performance, reliability. However, this hundred percent reliability is at the expense of communication channel resource utilization. With the advent of the Internet, VoIP began to prevail. IP telephony can be free or cheap, but the quality of the call is not guaranteed. Because in the Internet, the sound signal is compressed and transmitted in the form of IP packets, and the communication channel is non-exclusive. In other words, even if the two sides did not hang up the phone, as long as the two sides do not speak, will not occupy the channel resources. This kind of communication technology developed from it field, although the cost is greatly reduced because of the extremely high channel resource utilization, but its performance and reliability lack stable guarantee, it is difficult to apply to the occasion of higher service level.

In recent years, telecom operators have also realized the cost advantages and flexibility advantages of virtualization, but the doubts about performance and reliability make it difficult for them to step forward. Wind River is not a traditional it vendors, but has been with the equipment manufacturers with the company of embedded software vendors, customer base, including many of the world's top telecommunications equipment manufacturers. Therefore, the Wind River has long been very understanding of the needs of telecom operators, and embedded software technology rather than traditional it software technology to meet the needs of operators. As far as the operating system itself is concerned, the real-time operating system (RTOS) has always been a special category, with a special entry threshold, while the RTOS of the Wind River Company has maintained the status of "fact standard" in the industry. It is this kind of technological development that makes the Wind River Company in a unique position, has the ability to provide higher performance and reliability of the NFV solution, can become worthy of telecommunications operators and equipment manufacturers Trust partners.

Strong vertical integration in this year's MWC, the Wind River and China Mobile to display C-ran base station, its core product is the Feng River Open virtualization. This is a Type II virtual Machine Manager, with dedicated hardware accelerator on the Intel server to provide carrier-level open source real-time kernel virtualization function, this is the Wind river advantage of a reflection. Wind River Open virtualization enables the onsite display of general-purpose servers to achieve performance close to dedicated hardware, providing Industry base stations that strictly comply with ETSI NFV Standards Group requirements.

Optimized for open source KVM (kernel-based virtual Machine, kernel based VM) technology to enable it to deploy network services and achieve carrier-level performance and reliability. Wind River provides the whole industry with open source technology, standardized hardware provided by the carrier-level solution, which is unique in the industry. Open source and open standards, these are already fully enjoyed in the IT field advantages, due to performance and reliability has been unable to achieve the level of assured operators, resulting in difficulties in the field of network communications to play an effective role. Now, through the Wind river operator-level optimization, and equipped with perfect after-sale support, so that the use of open source, standardized software technology NFV can be telecommunications equipment manufacturers and operators to accept.

Since its inception more than 30 years, has been able to grasp the market demand trends, while adhering to their core competencies, in between the two to achieve the best balance, that is, insight into demand and meet the needs of the perfect combination, which is the Wind river and even many enterprises the root cause of success. Full-industry cooperation and deep NFV with the new generation of SDN, NFV, traditional network services are built on the fixed-function proprietary equipment, it is difficult to meet future telecommunications network market demand, especially high growth and flexibility.

To help operators cope with these challenges and resolve the conflict between performance, security and cost, the Wind River uses open source kernel virtual machine technology and sophisticated Linux distribution kits to build fully integrated and performance-Optimized SDN and NFV solutions, Can be used in the dedicated operating system and dedicated hardware to run a number of applications, functions in the next generation of network equipment, so as to help operators successfully realize network transformation. The main strategy of the Wind River is based on SDN and NFV, stripping out the network function from the hardware through abstraction, specially optimizes, realizes the function of high performance, real-time and deterministic, and reduces the delay. Reduce operating expenses (OPEX) and capital expenditure (CAPEX) costs by consolidating hardware and software, reducing footprint and energy consumption, and increasing operational support efficiencies.

Through SDN, NFV, Wind River can help operators to better utilize idle network components to improve network efficiency, and to run new solutions on existing standard server platforms. For example, the Wind River River Carrier Grade Communications Server, a joint demonstration with HP at MWC and Hewlett-Packard, has been implemented for network device providers and service providers on HP BladeSystem carrier-level blades etsi/ NEBS Level 3 certification levels of platform, in terms of performance, economy and energy saving are satisfactory performance.

Coupled with the Wind River world-renowned support and service team, enough to provide operators with no worries to protect.

For example, the Wind River has launched a virtualization solution in the Wireless access Network (CRAN). Mobile operators deploying 4G wireless networks are looking for new ways to reduce the cost of wireless data, while Cran divides base station functionality into baseband units (BBU) and RF pull-away headers (RRH). The BBU includes the baseband 1th layer, the base station (BS) 2nd layer and the 3rd layer function. The RRH has a low-noise amplifier (LNA), an intermediate frequency module, and an antenna. The interface between BBU and RRH is defined by the general public Wireless Interface (CPRI) and the open Base Station Architecture Initiator (OBSAI) specification. This new architecture has enormous potential for saving such costs.

There is a big difference between embedded software and PC software ecosystem. PC software developers have little need to think about which company's software will run on PC hardware platforms, and embedded software is closely related to hardware chips and architecture platforms. This gives embedded software vendors a unique ability to optimize software for specific hardware.

At the same time, the Wind River has become a subsidiary of Intel, with the chip manufacturers more closely related. For example, Wind River Linux has been fully integrated with Intel DPDK, providing built-in high-performance optimizations for fast packet processing. The combination of Intel DPDK packet Rapid transfer capabilities and NFV applications enables High-performance solutions for many network devices, security devices, high-speed mobile and broadband devices.

Wind River with customized services and support to help customers build, integrate and manage their Intel DPDK solutions. Wind River provides services including architecture consulting, design and integration, protocol porting, performance tuning, and validation for Intel DPDK. Also, the Wind River Training course includes the architecture, application, and how to set up application interfaces (APIs) for Intel DPDK. Wind River Company in MWC 2014 with HP to demonstrate for the telecommunications business providers and network equipment suppliers to optimize the requirements of the carrier-level NEBS server, can provide operators expect flexibility and scalability, The Wind River Company's telecommunications expertise and mature and reliable technology can allow users to enter the fully ready state, quickly play NFV advantage.

Thus, the Wind River with its own embedded software advantages as the foundation, with the chip manufacturers, machine manufacturers and operators to establish a network to promote the transformation of the complete system, can help operators to make good use of SDN, NFV and other new technologies, fully meet the future of the Internet and cloud computing environment needs.
