Smart Home wiring generally has the following five methods:
1. Star Connection 2, bus connection 3, Power Line Carrier connection 4, infrared connection (IR) 5, Wireless RF) Connection
1. From the perspective of stability, star connections are the most stable and reliable, followed by bus connections, Power Line Carrier connections, infrared connections, and Wireless RF connections. Traditional security systems use Star connections, so they are also the most reliable.
Although bus connections a
Practical Analysis of DNS multi-point deployment IP Anycast + BGP
Most of the Multi-Point deployment in the DNS field uses the IP Anycast + BGP mode. In this mode, you do not need to purchase additional equipment, and the deployment is flexible and diverse. However, like all other technologies, IP Anycast + BGP technology can play its biggest advantage only in the appropriate fields and scope.
As the Internet continues to grow and the number of Internet users increases, most websites or DNS serv
China's wireless routers are developing rapidly. So I have studied the parameter settings in the wireless routers. I would like to share with you here, hoping to help you. As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has a very direct relationship with wireless signals.
In fact, to make the wireless router in a very stable state, you must make a series of reasonable setting
With the development of China's routing industry, many emerging technologies have emerged. IP routing technology is widely used in routing technology, here we will mainly analyze the practical principles that should be followed when using IP routing technology, from the perspective of the transmission network, I think it is necessary to carefully check whether it has the Bandwidth Reservation for processing QoS and users' mobile terminals in the whole IP environment.

Ningbo often needs to download design drawings from foreign customers' servers for production. When downloading, the network management system generally does not want to be affected by the Internet access or downloading of general users. Therefore, you can apply for two lines: Generally, both lines are open for Internet use; however, when special work is required, it can be controlled to retain specific lines for a large number of download tasks to ensure that important data can be transmitted

. Strictly speaking, IP balancing is equivalent to the superposition of two or more single WAN products.
Second generation: Server Load balancer or Dual Network
The second generation of Multi-Wan technology includes two types. One is balancing, and the other is shunting.
The first type is Server Load balancer. It allocates and schedules all Intranet Session requests to bind and aggregate bandwidth. Server Load balancer is more advanced than IP address balancing because it processes sessions rath
rapid decline in profits in the traditional telecom operation market makes operators urgently need a value-added profit margin beyond ordinary narrowband telephone services, and broadband is regarded as the next wave of growth. It is undoubtedly tempting for carriers with traditional telecom networks to use DSL technologies promoted by the original network resources.
In the last round of man construction boom, China's broadband access technology main
Given the massive investment in DSL broadband access services, it has become a matter of widespread concern for carriers to use existing resources to optimize the current network, reduce O M costs, and provide richer services. As a world leading information technology manufacturer, Siemens has been committed to the Construction of China Telecom Networks for a long time. Apart from leading ADSLoverISDN/POTS solutions, Siemens has the latest insights o
on providing good outdoor coverage rather than indoor coverage. Therefore, the number of users of the third-generation communication business in early broadband code division multiple access (WCDMA) is much lower than that of the second-generation communication business.
In addition to ensuring higher service quality (QoS), the dedicated indoor coverage system also allows operators to win more roaming users, because most roaming users enable the automatic selection of public land mobile network
Headquarters and implement them through the smart routing technology of VPN. When the branch is connecting to the headquarters for VPN, you can intelligently select the corresponding line of the Headquarters for access, and the data packets sent back from the Headquarters network will also be returned from the fastest line. Without the need to purchase specialized Server Load balancer equipment, users can increase the network access speed across carriers
. The combination of these key factors can help manufacturers of optical fiber access network devices provide important features pursued by carriers: reliable customer service supply can be achieved through the existing infrastructure of operators, it provides flexible user interface support and good scalability for current and next-generation services.
Reliable network and device redundancy policies
The ADM622 device provides various network and devi
manageability. It is very difficult to manage user permissions. Generally, users can only pay by monthly subscription. However, it is difficult to control user traffic and access duration by attaching devices or modifying devices ). Second, poor network performance. The work of Ethernet broadcasting leads to insufficient isolation between users. User information problems and broadcast storms often occur.
These two key problems cause many defects in the services provided by the LAN access method
and its corresponding encapsulation, user authentication (combined with the authentication server), automatic configuration of the user end, and QoS service guarantee. Physically, A Broadband Network Gateway can be either a device or multiple devices. It can be used to implement a broadband access network remote server, Dynamic Host Configuration Protocol (DHCP) server (or DHCP repeater) and router functions.
Access nodes, Ethernet convergence networks, and broadband network gateways belong to
Fiber-optic access networks are still commonly used. So I studied the new challenges of fiber-optic access networks to meet the "full-service" operation. I would like to share with you here, hoping they will be useful to you. Generally, end users only care about the service types provided by carriers and the "integrated" and "one-stop" experience. Therefore, only by providing integrated services can operators increase user loyalty and occupy a greater
expansion: the first batch of applications of the Multi-Wan VPN Router in China occur in Internet cafes and residential areas. To meet the needs of many users, increasing the bandwidth through the Multi-WAN router has become the most direct choice. In addition, some users find that the function of multiple WAN routers can connect to multiple ADSL to replace the optical fiber. Because the bandwidth cost of the optical fiber is much higher than that of ADSL, the bandwidth cost can also be reduced
The WiMAX solution is also an excellent choice for carriers that lack local access resources.

Although the description of Ultra-Wideband is not detailed, it does help to separate this technology from the traditional "narrow band" system, or the updated system mainly refers to the "Broadband" system of the future 3G cellular technology described in the document. There are two main differences between ultra-wideband and other "narrowband" or "broadband. First, the ultra-broadband bandwidth is defined by the
by traditional operators. However, there are also significant shortcomings, because the application platforms must be different and have poor connectivity or cannot communicate with each other at all. Therefore, once a telecom operator chooses an application platform, business Development is also limited by this application platform. In addition, the interconnection of this business model can only be achieved at the network layer, so due to factors such as interconnection, the operator can only
value-added content applications (developed by third parties or carriers) will be implemented based on the enabling platform. In 3G environments, currently, the enablement Technology Platforms available can be roughly divided into four categories: WAP platform, multimedia information transmission platform, location-based application platform, and mobile e-commerce platform, with the development of terminal performance and wireless technology, more en
