The end customers in smart buildings are usually office organizations. Therefore, the information points are densely distributed, and the requirements for service quality, functions, and security are much higher than ordinary residential users. In addition to accessing computers, smart building networks also bear various A kind of data transmission task of building automation system, such as monitoring, lighting, air conditioning, electrical and so on. Therefore, the intelligent building network needs to have the characteristics of reliability, security, and openness, and also consider the special needs of commercial users. With the advantages of complete product line, high cost performance, and rich functions, MOBair provides a comprehensive solution for the construction of intelligent building network. For buildings of different sizes, MOBAL has proposed corresponding solutions to meet the needs of specific customers to the greatest extent.
Mobile medium-sized intelligent building network solution
As shown below:
Taking into account the characteristics of dense data points and large business volume in smart buildings, we use full Gigabit switches as the core of the network, and use two-tier Gigabit uplink and stackable 100M switches as access switches. At the same time, we consider firewalls and wireless Access and other services.
Core exchange:
We choose the AT-9816GB full Gigabit multi-layer switch in the Claymore 9800 series of Mobile as the core switching equipment of the intelligent building network. Mobile Claymore AT-9816GB core switch can provide up to 32Gbps full line-speed throughput, 24Mpps line-speed multi-layer forwarding capability, and support up to 16 GBIC interfaces (including SX/LX/LX25/LX40/LX70/1000BaseT, etc.). Insert GBIC modules as needed, reducing initial investment and ensuring scalability. The access layer, server group, routing switch and other equipment of the network are all connected to the core switch through Gigabit multi-mode fiber.
AT-9816GB’s outstanding 3-layer/4-layer switching performance is designed for users who have strict requirements on performance and service quality. Combining with the rich and powerful software features of AlliedWare from Mobile, AT-9800 can be ideal for construction The convergence network provides a complete solution. AT-9800 switch supports a rich set of Layer 2/3 features, including static routing, routing protocol set (RIP/RIPv2, OSPF, BGP-4, IS-IS), multicast protocol (IGMP, IGMP Snooping, DVMRP, PIM) -SM, PIM-DM), support IP routing, IPX routing and Appletalk routing, 4096 VLANs and flexible link aggregation function (LAG) and so on. Its load balancing function can help users more reasonably deploy network traffic for accessing public resource groups, thereby greatly improving network utilization.
The AT-9816GB switch also supports a firewall based on state detection. The firewall has passed the ICSA certification. It can provide effective protection for the internal network through the detection of the content of the data packet and the detection of the connection status. It can provide a wide range of anti-DoS attacks, including: Ping of death, SYN/FIN flooding, Smurf attacks, port scanning, fragmentation attacks and IP spoofing. Once it is attacked, it can automatically report to the police via E-mail. Different Ethernet ports can be divided into intranet and extranet, and establish a DMZ zone.
Access exchange:
We use MOBAL’s AT-8000 series switch as the access switch. The AT-8000 series has many varieties, which can be selected according to the needs. Among them, the AT-8024M with 24 10/100TX ports and two expansion slots is most suitable for the application of intelligent buildings. The expansion slots can be inserted into 10/100/1000BaseT modules. , Various 1000M fiber optic modules (multi-mode and single-mode), 100M fiber optic modules (multi-mode and single-mode), and special stacking modules can also be inserted to provide full-duplex 2Gbps stacking bandwidth. Through the unique intelligent stacking (Enhanced Stacking) technology, AT-8000 series switches can support up to 24 stacks, and only one IP address can manage all the switches in the stack.
The rich features of the AT-8000 series include 802.1Q VLAN tagging, which can divide different VLANs for different customers to ensure security. The AT-8000 series also supports 802.1p queue priority technology to support differentiation of large-scale networks and prioritize transmission. When the network administrator’s bandwidth resources are tight or there are data that must be sent first, the AT-8000 series can configure the priority of priority transmission for these data streams. The AT-8000 series also supports IEEE802.3ad and provides a maximum of 4 10/100M ports or 2 1000M ports aggregation, which can meet the needs of customers who need large-capacity data transmission. The AT-8000 series provides adaptive and broadcast storm control capabilities for each port. The automatic MDI/MDIX function supports easy connection to any port of other switches.
In terms of reliability, MAC-based port-level security can prevent unauthorized workstations from accessing the switch. The IEEE 802.1w-based Rapid Spanning Tree Protocol (STP) can achieve rapid convergence, minimize network failure time and minimize data packet loss. At the same time, the AT-8000 series supports TACACS+ and RADIUS authentication, which can centrally manage access control to a large number of network devices . The AT-8000 series also supports IEEE 802.1x port authentication. AT-8024M is equipped with a redundant power supply system RPS3004, equipped with a backup power supply of up to 4 units, which improves fault tolerance and normal network working time.
Wireless access:
Wireless access is becoming more and more popular in buildings because of its convenience and mobility. In meeting rooms, restaurants, coffee shops, and other leisure places where people flow and are difficult to wire, wireless LAN provides a powerful solution for high-speed access networks. In this solution, we choose Mobile’s AT-WL2411 as the wireless bridge and AT-WCL452 as the wireless access network card to solve the wireless access problem of smart buildings. AT-WL2411 is a carrier-class wireless bridge that supports 802.11b, which can realize seamless roaming of wireless LAN in buildings. In addition, AT-WL2411 also supports IP tunnel (support roaming between subnets), DHCP server, WEP64/128 encryption, automatic load balancing, network redundancy, 802.1x authentication, Radius authentication, IGMP multicast snooping, SNMP network management Abnormally rich functions such as to meet the application of carrier-grade wireless local area network.
Cooperate AT-WL2411 with Mobile’s wireless network card product AT-WCL452 to obtain a complete wireless local area network solution, and to maximize the reliability and security of the connection.
Mobile large-scale intelligent building network solution
Considering that there are more floors and greater business volume in large buildings, core equipment with larger capacity can be considered, as shown in the figure:
The large-scale building network uses the same network structure as the medium-sized building, but the core equipment is replaced by the Mobair core switch AT-SB4008 with greater data throughput, richer interface types, and higher reliability.
AT-SB4008 has 10 slots (8 of which are load slots), provides up to 128G switching matrix, supports up to 64 Gigabit ports, and also supports 10/100M ports. It is a true carrier-class product. AT-SB4008 provides many excellent features, hardware-based full wire speed, non-blocking multi-layer switching, support for IP/IPX routing, flexible deployment of policy-based QoS mechanisms, rich multicast features, simple and efficient control functions to facilitate user management and maintain.
In order to ensure high reliability, the AT-SB4008 chassis uses passive backplanes, redundant engines, 2+1 power supply redundancy, and hot-swappable technologies to provide users with high-availability solutions.
Summarize
Relying on its rich and powerful product line, Mobile has fully considered the characteristics of intelligent buildings, and can provide corresponding solutions for buildings of different sizes. Compared with other manufacturers’ solutions, Mobile’s intelligent building network solution has obvious advantages in terms of cost performance.
