[Learning favorites] compares the main advantages and disadvantages of circuit switching, packet switching, and group switching in multiple aspects

(1) circuit switching: Before communication, a physical channel exclusive to both parties must be established between the two parties (composed of the switching devices and links of both parties ), therefore, it has the following advantages and disadvantages. Advantages: ① Because the communication line is dedicated to users of both parties, the data transmission

Application of Optical Switching Technology in Communication Networks

, then, the Air Separation switching technology is used for link exchange at all levels, and the destination end outputs the corresponding optical signals by using the wavelength division switching technology. Then, the signals are merged and output separately. Common exchange technologies include air division-Time Division mixing, Air Division-wavelength divisio

Graph core technology of All Optical Networks: optical switching technology (1)

In modern communication networks, dense wavelength division multiplexing (DWDM) optical transmission networks make full use of the huge bandwidth resources of optical fiber to meet the explosive growth needs of various communication services.

Power supply circuit switching and lithium battery charging circuit design

the statuses are normal, the charging can be performed, and the back-level load regulator works normally.. This is becauseWhen the charging management IC is powered on, it needs to detect the status of batThe input pin of the ldos is also connected to the branch connecting the bat and the lithium battery cathode, which will affect the working status of the bat pin, causing the charging management IC to enter the streaming charging phase. Connect the bat pin and the voltage input of the Charging

The principle of optical burst switching and the structure of network nodes

Dense wavelength division multiplexing (DWDM) technology provides a huge transmission capacity for communication networks, and gradually becomes the mainstream transmission technology. With the maturation of DWDM technology and the rapid growth of transmission capacity, the pressure of traditional electronic switching system is increasing, and the introduction of optical

Computer network series-what is circuit switching and packet switching?

Group First, let's look at the concept of the next grouping. The so-called grouping is to divide a packet into smaller packets. For example, for a 10GB packet, it is not always a one-time delivery of the past bar, but it is divided into a number of small packets sent past. Structure diagram for each block of data:File headers are typically descriptive data, such as source and destination addresses, data types, and so on. The data part is what is really going to be communicated to the objectCircu

Comprehensive Analysis of Optical Burst Switching Technology and Its Research

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprec
