Case of intelligent construction of Shandong building

Shandong popular press is the most influential publishing unit in Shandong Province. Its publishing public is the newspaper with the largest circulation in Shandong Province, and it is also one of the eight newspapers with the largest circulation in China, occupying an important position in the same industry in the country

Shandong building is a newly completed modern building, which integrates newspaper office, hotel, catering and entertainment. It can be called a masterpiece of diversified and comprehensive intelligent building

network design network design goal

closely combine the design concept of the new generation of intelligent building network with the characteristics of the application in the publishing industry, and build a model of the new generation of intelligent building network in the publishing industry

network design requirements

according to the demand analysis of the application in the publishing industry and its requirements for the network, the network design follows the design requirements with high performance, high reliability, high security, and advanced quality of service (QoS) as the core

new generation intelligent building network leading technology

the combination of Gigabit Ethernet and layer 3 switching technology is the new generation intelligent building network leading technology, and runs through the design idea of high reliability, high security, high cost performance and advanced quality of service (QoS) based on high-performance network

network logic design

network logic design integrates network level design, topology design and IP sub design

1. Hierarchical design

network hierarchical design is usually divided into three layers, namely core layer, distribution layer and access layer

the building network nodes are distributed in three areas: Graphic office area, office area and guest room area

according to the different requirements of the application in each region, the corresponding hierarchical design for the correctness of its data is adopted

because the graphic office area and guest room area need to transmit data, images, voice and other media, in order to fully ensure its performance and reduce transmission links and transmission delay, the idea of two-layer design is adopted, namely the core layer and access layer

referring to the overall network design drawing, the design of the whole network level is as follows:

the switch on the third floor of Shandong building is mainly based on the network topology diagram

the core layer adopts two accelar8600 and one accelar1200 routing switches

the graphic office area adopts a two-tier structure, and the access layer adopts accelar8600; The office area adopts a three-layer structure, the distribution layer adopts accelar1200, and the access layer adopts baystack450; The guest room area adopts a two-story structure, and the access layer adopts baystack450; 2. The network topology refers to the overall design drawing of the network, and the overall design drawing of the graphic office network of Shandong building

the full mesh structure is adopted between the three accelar8600 on the core floor

partial mesh structure is adopted between the distribution layer and the core layer

partial mesh structure is adopted between the access layer and the core layer or access layer

in the graphic office area, accelar8600 of the access layer is connected to the core layer nodes by double links

in the office area; The overall design of the office network of Shandong building

accelar1200 on the distribution layer is connected to the core layer nodes by double links respectively

baystack450 of the access layer is connected to the nodes of the distribution layer by double links

in the guest room area, baystack450 in the access layer is connected to the core layer nodes by double links; According to the regional characteristics of the building network system - Graphic office area, office area, catering and entertainment area, the IP sub design divides each business department into an IP sub, and the servers of each department are divided into corresponding sub, The shared server uses VLAN method based on IP sub to map to the multiple sub nodes of the phase mechanics experiment results. The key lies in whether the measurement signal is reliable. The communication between different subsystems is realized through policy based routing and access control

physical network design implementation physical network design is divided into flow design, main node design and function module design

1. Traffic design

according to the analysis of business traffic, the principles of load balancing and bandwidth matching are adopted in traffic design

the three core nodes are interconnected through a full duplex Gigabit link to realize a high-speed and reliable transmission channel with full duplex 8gbps load balancing, forming a high-speed backbone of the building network

the distribution layer nodes are connected to the core layer nodes through four full duplex Gigabit links to ensure high-speed and reliable transmission of 8gbps load balancing

when the access layer node passes through two full duplex ports, it is necessary to select the connected COM port to connect the online megalink directly to the area layer. Otherwise, the product shrinkage of each cavity will not be 1 to the central node, ensuring the high-speed and reliable transmission of 400Mbps load balance

the client provides a flexible 10m or 100m adaptive access mode

2. Main node design

building node types can be divided into: core layer nodes, distribution layer nodes, access layer nodes

the core layer nodes adopt two accelar8600 routing switches, which are distributed in the network management center (F10) on the tenth floor, and the two are interconnected by four 1000m optical fibers; The other accelar8600 is placed on the first floor (F1), and the two accelar8600 of F10 are connected through two 1000m optical fibers respectively; In the graphic office area, four accelar8600 are used at the access layer node, and each accelar8600 is connected to the core layer node by two 1000m optical fibers; In the office area,

the distribution layer node adopts four accelar1200, and each accelar8600 adopts two 1000m optical fibers to connect to the core layer node

access layer node baystack450 stack, which is connected to the distribution layer accelar1200 by two 1000m optical fibers respectively; In the guest room area

access layer node baystack450 stack adopts two 100m optical fibers respectively connected to the core layer f1accelar8600; 3.
