Huawei end-to-end solution
Huawei integrated the leading advantages in the field of routers and optical transmission, and launched the industry-leading end-to-end 100G solution. 100GE line cards and ports were first applied in the long-distance backbone, and gradually extended to the backbone edge and metropolitan area networks. client needs The rapid growth of network traffic has promoted the continuous growth of the line card capacity of routers and transmission equipment, from 1G, 2.5G, 10G to 40G and 100G. For operators, 100G line card and interface capacity means greater single device capacity, lower power consumption and cost per unit bandwidth, which can effectively help operators increase bandwidth, reduce operation and maintenance costs, and help ultimately Users get a more natural remote communication experience and a more convenient information acquisition experience. Solution introduction and its advantages With years of technical accumulation and a deep understanding of customer needs, Huawei has integrated its leading advantages in the field of routers and optical transmission to launch an industry-leading end-to-end 100G solution. 100GE line cards and ports will be first applied in the long-distance backbone (CORE), and will gradually extend to the backbone edge (EDGE) and metropolitan area (METRO) networks. In the long-distance backbone, through the NE5000E router cluster system that supports 100GE interfaces and the 40/80 wave & TImes; 100G OSN6800 / 8800 OTN system, a 100GE long-distance transmission is achieved, and the openness and reliability of the entire network are fully improved. It is suitable for network planning, construction and operation and maintenance. At the backbone edge and the core of the metropolitan area, the NE5000E cluster router 100GE interface direct connection solution is adopted to simplify the network architecture on a large scale and enable operators to easily respond to the business development trend of traffic localization. End-to-end deployable solution At present, the initial transmission distance of the 100GE optical module is only 10 kilometers. The 100GE interface is first applied in the core plane of the long-distance backbone, which requires close cooperation between the core router and the transmission system. Huawei OTN series products are based on 100G optoelectronic modules and core chips independently developed by Huawei, and integrate advanced coding and modulation methods such as OPFDM-DQPSK, oPDM-DQPSK, ePDM-QPSK, and realize 1500 km ultra-long distance transmission, which increases the transmission capacity of single fiber. To 8T. Cooperate with leading high-capacity OTN switching, intelligent ASON and other technologies to realize the continuous evolution of WDM transmission network to a larger capacity, more flexible, efficient and highly reliable network. The interoperability of routers and transmission is also a key point that operators must consider when building an end-to-end 100G network. Huawei gives full play to its advantages of having two industry-leading product series, both router and transmission, as well as active participation and in-depth comprehensive understanding in the field of 100G standards, to achieve standardized interoperability between 100GE routers and 100G transmission, which can provide operators with complete End-to-end 100G solution. Green and sustainable bandwidth growth guarantee The growth of bandwidth and the improvement of user service experience quality cannot be at the expense of unlimited power consumption growth and payment cost growth, otherwise the growth cannot be sustained. Huawei's 100G solution introduces a number of low-power technologies, which reduces the power consumption per 10G by 57% compared with the current system in the industry and reaches a leading level of <40W / 10G, effectively supporting the continuous growth of bandwidth. Enhanced service quality assurance EQC From the point of view of the actual operation of the operator's network, it is difficult to fully guarantee the need for end-to-end service quality assurance only by the increase in bandwidth, such as: Many operators have insufficient bandwidth to ensure that the video quality of IPTV cannot be guaranteed, nor can they accurately locate the specific fault location. P2P services have gradually become the main traffic of the Internet. P2P terminals are not clear about the topology of the network, resulting in more than 90% of IP traffic flowing to the backbone, instead of being localized like the traditional telecommunications network, which has caused continuous expansion pressure on the backbone and terminals. Reduced user experience quality. The increase in bandwidth and the intelligentization of access terminals have made DDoS-based network attacks a very important factor affecting network quality. Many network security incidents that have occurred have also exposed the vulnerability of traditional networks. To ensure an end-to-end business experience, the network cannot provide only one bandwidth, but requires more intelligence, and the deployment cost of such intelligence is limited. Huawei refers to this type of deployable quality assurance measures as EQC (Enhanced Quality Control). EQC is a full-network solution that can be deployed in various locations in the metropolitan area and backbone. Huawei's solution solidifies some EQC capabilities into hardware and chips to effectively reduce deployment costs. EQC is a necessary measure to cope with bandwidth growth, ensure service quality, and reduce operator's operating costs. EQC mainly includes the following content, Huawei will continue to optimize and enhance its capabilities in subsequent solutions: Scalable business support: able to identify businesses that require special assurance and give special quality assurance measures; Flow control and grooming: able to effectively control the flow of network traffic and optimize resource allocation; Business quality monitoring: able to monitor the status of business quality online so that problems can be discovered and eliminated in time; DDOS attack protection: able to protect the device itself and a network from DDOS attacks; Fast fault location: It is used in conjunction with service quality monitoring to accurately locate the faulty equipment or fault link when a service quality problem occurs. Solution application and customer benefits NE5000E has a core router that provides large capacity, high reliability and clustering capabilities, including 40G / 100G capabilities and rich reliability technologies. It can smoothly upgrade from single-frame expansion to back-to-back and multi-frame clusters to meet customers' future network growth needs. The IP backbone network is an important source of power for the development of broadband, security and business.
