Who is the "net red" of the new generation network? The answer is undoubtedly 5G. At the 2016MWC Shanghai, which ended not long ago, 5G has become the most dazzling label. Whether it is the international big T, the telecom equipment provider, or the chip or test manufacturer, it has the latest 5G big trick. With the advancement of national strategies such as "Internet +" and "Broadband China", the evolution of the traditional Internet to the mobile Internet to the "Internet of Everything", the deployment of 11ac wave 1&2 WLAN and the emergence of 5G, the new generation of networks is constantly converging and converging. What brings about not only the increase in speed, cost and efficiency, but also trigger the reconstruction of the network architecture. Can the network processor and switch chip in it be responsible for this? The new generation network expects the awakening of the Force 5G's "beautiful" can be expressed by key values ​​such as 1000x capacity increase, 100 billion+ connection support, 10GB/s maximum speed, and 1ms delay. In 2016, many manufacturers in Shanghai have demonstrated 5G related services, such as driverless cars and virtual reality scenes, which have proved the excellent performance of 5G in low delay, ultra high density and large capacity. With the help of all parties actively preparing for the battle, 5G has gradually approached. In order to meet the requirements of 5G network access to the network anytime and anywhere, the important indicators for 5G network construction are better flexibility and scalability, so SDN (software-defined network) and NFV (network function virtualization) will be in the 5G core. The network is popular, and the integration of the core network and the access network and the reorganization of network functions will also be applied in depth. This is just a new engine that drives the network model and technology “sublimationâ€. In the data center, enterprise network, campus network, and small and medium-sized enterprise network, with the changes in business and demand, the network upgrade and upgrade is also the trend of the times. For example, the data center is an application-oriented integrated service platform and the core infrastructure of future cloud computing. The demand is increasing. Its network equipment is growing at a rate of more than 40% per year. The next-generation data center proposes a more comprehensive network architecture for network equipment. More demanding requirements include support for unified switching architecture, high capacity and scalability, forwarding performance, and refined Quality of Service (QoS). The campus network is also changing. With the continuous enrichment of services, the rapid development of cloud computing, and the increasing number of user mobility scenarios, BYOD has gradually become a trend, and many new demands have been placed on the campus network, such as requiring the campus network to have end-to-end network quality assurance. Capabilities, with the ability to differentiate and secure specific services in real time, flexible, and flexible to adapt to business needs. At the enterprise network level, along with the IT of a large number of enterprises, the investment of IT customers is more active, and the mature technologies such as large-scale server clusters, virtualization, and big data all raise higher on the enterprise network. Business requirements. It can be said that the new generation network of convergence and convergence has already come to the fore, various communication and network services will be highly integrated, and various services emphasize open API interfaces and flexible configuration and customization capabilities. The traditional network architecture is already “difficult to meetâ€. . The industry has introduced new technologies such as SDN, NFV, and cloud to create a new network that is simple, intensive, agile, and open, enabling multiple network implementations and virtualization of services, and will once again release the "original power" of the network. The new generation of networks under the guidance of network reconfiguration has been "on the road." Converged networks trigger multiple re-challenge The development of next-generation network convergence has increased the need for network infrastructure for deploying scalable and flexible computing solutions across the entire network. “Searching for the rootsâ€, a new proposition of the convergence and convergence of the new generation network, can be targeted to the traditional network architecture and service transformation challenges. First and foremost is the convergence of wireless and wired convergence. Raza Eltejaein, head of product marketing at Marvell, said that the convergence of wired and wireless networks is accelerating, with wired bandwidth from 1 GbE to 2.5 GbE up to 10bE, wireless from 802.11N to 11AC, followed by 11AX, a trend that requires higher performance. The network processor to deal with. In addition, 2.5GbE has been widely used. How to make enterprises still use 1GbE infrastructure, and enjoy a larger 2.5GbE or more bandwidth without the need for architecture upgrade becomes a new challenge. With the continuous deepening of IoT applications, the number of connected devices in home and industrial applications has increased dramatically. The services carried by the network have also expanded from simple data communication to multimedia such as voice, image and video. The bandwidth requirements have been greatly improved. And the requirements of the router have also increased. Raza Eltejaein further pointed out that "in this process, operators and service providers also want to provide differentiated and high value-added services, which puts higher and higher requirements on the reliability of network operation." †Perceptible, reconfigurable, and evolvable is the evolution of the new generation of networks. "Therefore more and more software technologies become inevitable. Using virtualized network equipment based on SDN/NFV technology to replace traditional private network equipment can provide more flexible and efficient network equipment, providing an 'engine' for network transformation." Raza Eltejaein analysis said. With the increasing vertical application of the Internet of Things, security issues are becoming more and more serious, facing the uncertainty of the network environment, the main threats faced by the sensing layer, the security risks of the transport layer and the application layer, and providing a strong security system. Become the focus of the industry. All deployed and newly deployed infrastructure platforms, whether on-site or in the cloud, should be fully addressed from a system perspective. High scalability, self-virtualization capabilities of network devices, multi-service support, and network convergence all require breakthroughs. In order to achieve this high goal, it is clear that we need to break through the "basic" - network processor and switch chip to achieve higher performance, more bandwidth and more scalable chips, with acceleration, security engine and line The engine can be solved one by one. Network processor and switch chip comprehensive upgrade response "The scalability, virtualization capabilities, multi-service support and network convergence requirements of network equipment make network processors need to be fully upgraded in terms of integration, scalability and support for SDN." Marvell Vice President, Connection, Michael Zimmerman, general manager of the Storage and Infrastructure Network (CSI) business unit, said. In the long-term design innovation experience of the network ecosystem, Marvell has launched the ARMADA 7000 and 8000 to meet market challenges. ARMADA uses Marvell's groundbreaking MoChi architecture and the industry's first ARM Cortex-A72-based system-on-a-chip (SoC) family with flexible scalability. "From the perspective of bandwidth, not only can 11AC be run, but it can even run 11AX in the future. It also supports 1 GbE, 2.5 GbE and 10GbE, as well as SATA3 and USB3.0. It also integrates multiple 10GE ports and packet processors for security. The hardware and acceleration devices provide hardware acceleration engine and flexible configuration, support CPU and I/O full virtualization, fully support the requirements of software-defined network SDN. In addition, it has integrated functions, as well as high scalability and software compatibility. Developed in an optimized way to match a variety of IP networks, data centers, enterprises, small and medium-sized businesses, etc." Raza Eltejaein concluded. At the switch level required for next-generation networks, Michael Zimmerman believes that on the one hand, bandwidth requirements are higher, connectivity beyond 2.5GbE is required, and no architecture upgrade is required; on the other hand, network administrators want to make the overall network connection a single Entity, supporting technologies such as physical layer devices (PHYs), implements a solution that combines the switch with the physical side. Aiming at this need, Marvell's switch chips, Prestera Aldrin and Alleycat, are available to provide a solution for the switch and the physical side. According to reports, Aldrin supports high bandwidth up to 10GbE to support wider, larger backplane connections. Aldrin is the industry's first to support 16 or even 24 or even more than 10 10GbE interfaces. Alleycat is the industry's highest performing, highest density, GbE-capable product line, using NBASE-T converter technology. It has a dedicated 40GbE stack and is the industry's first product to support 40GbE stacking. The Alleycat 3X is the industry's first 2.5GbE switch to support 24 interfaces. Especially worthy of the new chip Prestera 98DX325x, with Marvell's 88E2040 quad NBASE-T PHYs, can efficiently support the convergence of wired and wireless networks, while increasing 1GbE to 2.5GbE bandwidth. In addition, Marvell can introduce the SDN and switch abstraction layer interface into the 2.5GbE campus environment through the 98DX325x, providing a complete software protocol stack Turnkey solution for private cloud deployment.
