During the evolution of the next generation network, how to guarantee the high performance, high utilization rate, low power consumption and optimization of traffic and management of the existing network is the urgent task of the current operators.
Putting aside the surface and looking at the technology, it is not difficult to find that the low-key semiconductor industry is providing strong support for the improvement of the network with its solid, stable and innovative technical strength.
Opportunities from next-generation mobile technology
"Communications World Weekly": This year is the first year of the blowout of 3G development and LTE. It is also the 30th anniversary of the establishment of LSI. The proliferation of data services and the deployment of next-generation mobile technologies have brought LSI with 30 years of experience. What are the market and technology opportunities?
Zhang Wei: 3G and LTE are advancing rapidly across the country. LSI sees a huge growth opportunity for the next generation of high-performance wireless networks, and this is also one of the key development areas for LSI in the future. From 2G to 3G, LTE, and various high-profile wireless new network technologies proposed by the industry chain, such as Huawei's Single RAN and Aran's lightRadio, etc., have also brought more opportunities and development to LSI.
Through cooperation with operators such as China Mobile, we have seen that at this stage, operators have invested heavily in operating and service costs, but they have not been able to obtain satisfactory revenue. Users ’demands for bandwidth are increasing. How to ensure that all links of the industry chain can maintain good returns? These all require the support of advanced technologies and products.
In addition, traditional core network storage is no longer limited to the inherent model, and new distributed storage has brought new demands to the storage market.
LSI has noticed changes in the market, and has adopted an active strategy. Not long ago, LSI sold its external storage system business to help LSI focus more on the storage and network markets. At present, LSI has also established a product line for SSDs, striving for greater business opportunities in this communication revolution.
Semiconductor technology innovation eases network pressure
"Communications World Weekly": For the vigorous development of mobile Internet services, it seems that operators have repeatedly upgraded and optimized networks to fully meet users' needs for network quality and service experience, and LTE is still waiting for some time. From LSI's point of view, how can we resolve these conflicts as soon as possible?
Zhang Wei: Indeed, the current network user experience is not very satisfactory. Regarding how to avoid these contradictions in the replacement of old and new standards, LSI has taken several major measures to balance market demand.
First, the new generation of wireless access technologies have put forward the demand for soft programming multi-standards for basic equipment, which needs to reduce the optimization pressure of different network standards. LSI's multi-core Axxia communication processor, StarPro multi-core media processor and vector processor for next-generation wireless systems have technically realized the possibility of multi-mode software programming.
Second, wireless broadband data services often suffer from unbalanced network utilization. For example, at different times in different areas such as business districts and residential areas, the network load is too large during peak business hours, and the network utilization rate is low when the business volume is low. In response, LSI has launched a series of new solutions, including wire-speed deep packet inspection, programmable video acceleration, and advanced traffic management at the network edge, enabling operators to launch environment-aware strategic services and guarantee various services Different priority levels.
In response to the contradiction of wireless networks, LSI has also launched a series of Axxia communication processors based on multi-core processors and hardware acceleration engines. These products with unique architectures include packet classification, traffic management, server load balancing, and low-latency data. Features such as packet processing and deep packet inspection also greatly reduce system power consumption.
Third, deep packet intelligence is also very important. LSI's new processor can be built-in to intelligently check all data passing through the wireless network, helping operators understand the IP network situation and implement efficient management of it. This also helps to solve the problems of availability, delay and quality, and helps to effectively solve the problems of network coverage and security.
"Communications World Weekly": At the end of last year, Ericsson's new generation of mobile media gateways, which integrated LSI StarPro multi-core media processors and multi-core communication processors, have been put into mass production and attracted the attention of the industry. What other similar cooperation projects of LSI include? What kind of application trend is presented?
Zhang Wei: Wireless operators need highly scalable and powerful solutions to deal with the explosive demand for broadband and real-time video services. In addition to Ericsson, LSI has also launched media gateways and other products based on StarPro multi-core processors in cooperation with mainstream equipment manufacturers at home and abroad. .
At the same time, LSI is also developing a new generation of media gateway multi-core processors that support video + voice.
In technology migration, wireless operators focus on controlling capital expenditure and operating expenses while ensuring the best quality experience for customers. There are many standards for promoting upgrades, the most important of which are scalability and flexibility. In the base station, the solution should develop from a single field to multiple fields or multiple radios, and should support multi-Gb wired speed network scheduling and routing packet throughput in E-UTRAN. The solution must also support the IP and migration paths of traditional networks, and should achieve interoperability with 3G and 2G networks.
