Detailed Information on Routers

A router is a device that connects LANs and WANs in the Internet. It automatically selects and sets routes based on the conditions of the channel, and sends signals in the forward and backward sequence according to the best path. The router is the hub of the Internet, “traffic police.” Currently, routers have been widely used in various industries, and products of various grades have become the main force for achieving various backbone network internal connections, backbone network interconnections, and interconnection between backbone networks and the Internet. The main difference between a router and a switch is that the switch occurs in the second layer of the OSI reference model (data link layer), and the routing occurs in the third layer, the network layer. This difference determines that routing and switches need to use different control information in the process of moving information, so the way the two implement their respective functions is different.

A router is also called a gateway. It is used to connect multiple logically separated networks. The so-called logical network represents a single network or a subnet. When data is transmitted from one subnet to another, it can be done through the routing function of the router. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish a flexible connection in a multi-network interconnection environment, and can use different data packet and media access methods to connect various subnets. The router only accepts the source station or the information of other routers is an interconnected device at the network layer.

Core functions

1) Internal Integrated TCP/IP Stack

GPRS DTU encapsulates PPP dial-up protocol and TCP/IP protocol stack and has embedded operating system. From hardware, it can be regarded as a combination of embedded PC and wireless GPRS MODEM; it has GPRS dial-up Internet access and TCP/IP data. The function of communication.

2) Provide bidirectional conversion function of serial data

GPRS DTU provides a serial communication interface, including RS232, RS485, RS422, etc. are all commonly used serial communication methods, and GPRS DTU design in most of the serial data is designed as a “transparent conversion” mode, which means that GPRS DTU can The raw data on the serial port is converted into TCP/IP data packets for transmission without changing the original data communication content. Therefore, the GPRS DTU can be connected to various user equipment’s that use the serial communication without changing the user equipment.

3) Support automatic heartbeat and stay permanently online

One of the advantages of the GPRS communication network is that the GPRS terminal equipment is permanently online, so typical GPRS DTUs are designed to support the permanent online function, which requires the DTU to include automatic dialing on power and use of heartbeat packets to maintain permanent online (when long When there is no data communication, the mobile gateway will disconnect the DTU from the center. The heartbeat packet is a small data packet sent between the DTU and the data center before the connection is disconnected to keep the connection from being disconnected. It supports automatic disconnection of the disconnected line. , automatic redial and other features.

4) Support parameter configuration, permanent preservation

As a communication device, GPRS DTU has a wide range of applications. In different applications, the IP address and port number of the data center and the baud rate of the serial port are different. Therefore, the GPRS DTU should support parameter configuration and store the configured parameters in internal permanent storage devices (generally FLASH or EEPROM, etc.). Once powered on, it will automatically work according to the set parameters.

5) Support user serial port parameter setting

The serial port parameters of different user devices are different. When the DTU is connected to the serial port of the user device, the DTU must be set according to the actual parameters of the user device serial port to ensure the normal communication and reliable data transmission of the user device.

Application area

DTU has been widely used in power, environmental protection, LED information release, logistics, hydrology, weather and other industries. As shown in the above figure, the principle of application is the same, although the industry of applications is different. Mostly, DTUs are connected to industrial equipment, such as PLCs, SCMs, and other automation products, and then establish a wireless communication connection with the background. With the increasing development of the Internet, the use of DTUs has become more widespread.

Machine to machine refers to direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the data it records to application software that can use it. Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer.

More recent machine to machine communication has changed into a system of networks that transmits data to personal appliances. The expansion of IP networks around the world has made machine to machine communication quicker and easier while using less power. These networks also allow new business opportunities for consumers and suppliers.

Wireless networks that are all interconnected can serve to improve production and efficiency in various areas, including machinery that works on building cars and on letting the developers of products know when certain products need to be taken in for maintenance and for what reason. Such information serves to streamline products that consumers buy and works to keep them all working at highest efficiency.

Another application is to use wireless technology to monitor systems, such as utility meters. This would allow the owner of the meter to know if certain elements have been tampered with, which serves as a quality method to stop fraud. In Quebec, Rogers will connect central system with up to 600 Smart Meter collectors, which aggregate data relayed from the province’s 3.8-million Smart Meters.

A third application is to use wireless networks to update digital billboards. This allows advertisers to display different messages based on time of day or day-of-week, and allows quick global changes for messages, such as pricing changes for gasoline.

The industrial machine to machine market is undergoing a fast transformation as enterprises are increasingly realizing the value of connecting geographically dispersed people, devices, sensors and machines to corporate networks. Today, industries such as oil and gas, smart city, government, among others, utilize machine to machine technologies for a myriad of applications.

To further enhance the wireless M2M and IoT reliability, the H685 4G router with Ethernet provides multi-connection for get different applications.

1) Failover

With this using, usually you can get one SIM Cards from the mobile network, get one xDSL modem line and WiFi AP (conneced to Internet or Private Networks). Set the main line, backup lines for failover application. Once the main line is failed, the H685 switches to backup line smoothly, which makes the communication stable and reliable. .

2) Load Balancing and Link Bonding

Being a 4G Load Balancing Router, the H685 can utilise the embedded 4G module, the RJ45 WAN and WiFi Client connections all at the same time and share these WAN connections with the LAN users.

With channel link bonding, the H685 4G router makes two or more links are combined for redundancy or increased throughput. Channel bonding is differentiated from load balancing in that load balancing divides traffic between network interfaces on per network socket (OSI model layer 4) basis, while channel bonding implies a division of traffic between physical interfaces at a lower level, either per packet (OSI model Layer 3) or a data link (OSI model Layer 2) basis.

If you have business in M2M Field, E-Lins H685 4G will be an excellent choice. Meanwhile E-Lins have many other good M2M Routers cover 2g/3g/4g network, if you have interests, E-Lins surely can provide you a suitable M2M router for your projects.
