360 is safe as a sandbox, but it can still be done with extensions, and it is much safer than all browsers with IE kernel.
1. Open the 360 browser, and you can find the "extension" toolbar in the upper right corner of the browser

Zhengzhou railway station, located in Zhengzhou City, Henan Province, China, is a special grade station under the jurisdiction of China Railway Zhengzhou Bureau Group Co., Ltd. It is one of the eight comprehensive transportation hubs in China determined by the former Ministry of Railways of the people's Republic of China. It is an important part of Zhengzhou railway hub, and also a collection of high-speed railway, intercity railway, EMU train It is a comprehensive transportation hub integrating common speed trains and other passenger services
Zhengzhou station was built in 1904; In 1953, the reconstruction and expansion project of Zhengzhou railway station started; In 1956, the expanded station was put into use; In 1988, Zhengzhou railway station was reconstructed and expanded again; In December 1999, the main building of Zhengzhou railway station was put into useeffect: ignite all nearby enemies

the backplane bandwidth of a switch is the maximum data throughput between the switch interface processor or interface card and the data bus. Backplane bandwidth marks the total data exchange capacity of the switch, in Gbps, also known as switching bandwidth. The backplane bandwidth of general switches ranges from several Gbps to hundreds of Gbps. The higher the bandwidth of the backplane of a switch, the stronger the ability to process data, but at the same time, the higher the design cost< Generally speaking, the calculation method is as follows:
1) backplane bandwidth at line speed
the total bandwidth provided by all ports on the switch is considered. The calculation formula is port number * corresponding port rate * 2 (full plex mode). If the total bandwidth is less than or equal to the nominal backplane bandwidth, the backplane bandwidth is line speed
2) layer 2 packet forwarding line speed
Layer 2 packet forwarding rate = number of Gigabit ports × 1.488mpps + number of 100m ports * 0.1488mpps + number of other types of ports * corresponding calculation method. If this rate can be ≤ the nominal layer 2 packet forwarding rate, then the switch can achieve line speed when doing layer 2 switching
3) layer 3 packet forwarding line speed
Layer 3 packet forwarding rate = number of Gigabit ports × 1.488mpps + number of 100m ports * 0.1488mpps + number of other types of ports * corresponding calculation method. If this rate can be ≤ the nominal layer 3 packet forwarding rate, then the switch can achieve line speed when doing layer 3 switching
how to get 1.488mpps
the measurement of packet forwarding line speed is based on the number of 64 byte packets (the smallest packet) sent per unit time. For Gigabit Ethernet, the calculation method is as follows: 1000000000bps / 8bit / (64 + 8 + 12) byte = 1488095pps. Note: when the Ethernet frame is 64BYTE, the fixed overhead of 8byte frame header and 12byte frame gap should be considered. Therefore, the packet forwarding rate of a Gigabit Ethernet port with line speed is 1.488 MPPs when forwarding 64 byte packets. The packet forwarding rate of Fast Ethernet is one tenth of that of Gigabit Ethernet, 148.8kpps
* for 10 Gigabit Ethernet, the packet forwarding rate of one line speed port is 14.88 MPPs
* for Gigabit Ethernet, the packet forwarding rate of one line speed port is 1.488mpps
* for fast Ethernet, the packet forwarding rate of one line speed port is 0.1488kpps
* for the POS port of oc-12, the packet forwarding rate of a line speed port is 1.17mpps
* for the POS port of OC-48, the packet forwarding rate of a line speed port is 468 MPPs
the utilization of backplane bandwidth resources is closely related to the internal structure of the switch. At present, the internal structure of the switch mainly includes the following: one is the shared memory structure, which relies on the central switching engine to provide full port high-performance connection, and the core engine checks each input packet to determine the routing. This method needs large memory bandwidth and high management cost, especially with the increase of switch ports, the price of central memory will be very high, so the switch core becomes the bottleneck of performance implementation; The other is cross bus structure, which can establish direct point-to-point connection between ports, which has good performance for single point transmission, but is not suitable for multi-point transmission; The third is hybrid cross bus structure, which is a kind of hybrid cross bus implementation. Its design idea is to divide the integrated cross bus matrix into small cross matrices, and connect them through a high-performance bus. The advantages of this method are that the number of cross buses is reced, the cost is reced and the bus contention is reced; But the bus connecting the cross matrix becomes a new performance bottleneck.
