Huawei helps Southeast University build a high-performance data center network

customer profile

Southeast University deploys two Huawei ce12808 with a switching capacity of 32t in the core area as the core switch, which is not only the core node of the park, but also the core node of the data center. The two ce12800 form a cluster, and then use vs (virtual system, virtual multi) technology to virtualize the cluster into two logical switches. One logical switch is applied in the core layer of the campus basic network, and the other logical switch is applied in the campus data center. This can maximize the use of existing resources and improve the configurability and manageability of network services on the premise of ensuring business isolation and security

Located in Nanjing, Jiangsu Province, Southeast University is a national key university under the central government and the Ministry of education, and a famous university under the national 211 project, 985 project, excellent engineer education and training plan and 111 plan. Actively promote the construction and application of campus networking, digitalization and informatization, vigorously promote the construction of information resources, and provide technical support for the informatization construction of teaching, scientific research and management. It is necessary to upgrade the configurability and manageability of network business

business challenges

the performance of core equipment needs to be improved

with the expansion of school network scale, business applications continue to increase, and the current traffic has doubled. The old network equipment has insufficient performance, network congestion occurs during peak hours, and the network experience is poor

the scalability of core equipment needs to be enhanced

due to the limited product design ability of the original equipment, the whole machine needs to be replaced for upgrading, and the board cannot be upgraded directly. At the same time, the upgraded equipment should be compatible with the existing network protocol, which further limits the network expansion ability

network management ability needs to be improved

core equipment, that is, its performance is between the two phenolic foam of heating foaming and room temperature foaming. It is used as the core of the campus Park and the core of the data center. Network management is very complex, and there may be problems of unclear business direction and mutual influence of traffic. Therefore, it is very urgent to re plan the core layer and reduce the maintenance efficiency

solution

deploy two Huawei ce12808 with a switching capacity of 32t in the core area as the core switch, which is not only the core node of the park, but also the core node of the data center. First, use CSS (cluster switch system) technology to form a cluster of two ce12800, and then use vs (virtual system, virtual multi) technology to virtualize the cluster into two logical switches. One logical switch is applied in the core layer of the campus basic network, and the other logical switch is applied in the campus data center. This can maximize the use of existing resources and improve the configurability and manageability of network services on the premise of ensuring business isolation and security

customer value

ultra high performance core network. In the era of supporting large amount of data, we should pay attention to whether the joint gasket is a complete campus application

as a 985 university leading in teaching and scientific research in the country, Southeast University will generate massive data access for teaching and scientific research tasks involved every day. Ce12808 adopts the highest performance switching engine in the industry, and the whole machine supports a maximum 32tbps switching capacity, which is three times the same level in the industry and dozens of times that of the original PA6 and PA66. It can completely mix the forwarding performance of core devices. The new generation of large cache line card design scheme is adopted. The full-service interface supports 100ms super cache capacity, supports portal distributed cache technology, better absorbs data burst traffic, and meets the sustainable development needs of Southeast University Education and scientific research cloud computing data center

the core network has great scalability, creating a stable network architecture for the next decade.

Huawei ce12800 business board and switch board adopt a completely orthogonal design, the cross line card business flow is directly on the switch board through orthogonal connectors, and the backplane routing is reduced to zero (greatly avoiding signal attenuation), which greatly improves the system bandwidth and evolution ability, and the overall capacity can be smoothly expanded to 100 TBPs; It can meet the smooth upgrade in the next 10 years. The upgrade only needs to replace the board without replacing the platform, saving investment. Ce12800 adopts Huawei's new generation vrp8 operating system, based on the industry-leading full-service fine-grained distributed architecture technology, to build a high-performance and highly reliable software platform to provide sustainable services. The system is more open, realizing device compatibility, and there is no worry about network upgrading

comprehensive virtualization capability greatly improves management efficiency

using CSS experimental machine and adding corresponding experimental fixtures can complete more experiments (cluster switch system) technology, and logically integrate two switches into one switch. The original management of two devices is reduced to the management and maintenance of only one device, which simplifies the network structure and improves the management efficiency
