GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently developed by beacon network, were officially introduced to the market, this is an important step in improving the Ethernet switch Product Lin
low address, where the sp pointer executes the last stack address used
Here we introduce the second pointer bp, which is used to represent local variables in the range of this function (this ghost bp is used to indicate the starting address of these local variables. Note that, the starting address does not include sfp and ret)
Bp and sp are based on the following operating mechanisms:

Network control and bandwidth optimization are achieved through advanced QoS, precise rate limiting, ACL, and multicast services. Network security through multiple authentication methods, data encryption technology, and network access control based on user, port and MAC address sim
Meanings of VCC, VDD, Vee, VSS, and VPP
Version 1:
To put it simply, we can understand it as follows:
I. Explanation
VCC: c = circuit indicates the circuit, that is, the voltage of the access circuit;VDD: D = device indicates the device's internal operating voltage;VSS: S = series indicates the public connection, which usually refers to the public grounding terminal voltage of the circuit;Vee: negative voltage power supply;VPP: programming/erasure voltage.
Ii. Description
1. for digital circuits
When the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect vswitches: Stack and cascade.
1. GBIC and SFP

When a function call occurs in a program, the computer does the following: First, the parameters are pressed into the stack;The contents of the Save instruction Register (IP) are returned address (RET); The third is the base address that is sent to the stack(FP), then copy the current stack pointer (SP) to the FP as the new base address, and finally the localAmount of space, the SP minus the appropriate value. Take the following procedure as an example:
VMOs Field effect tube has the advantages of both the electron tube and the advantages of transistors, the power amplifier made with it sound mellow, sweet, dynamic range, frequency response is good, so in recent years in the audio equipment has been widely used. High-power field-effect tube power amplifier, electric. The road is more complex, the production and commissioning is also more difficult, and. The cost is also very high, so it is not suitable for beginners. The following introducti

Q: What is a current controller?A: If the output parameter of the device is related to the input current parameter, the device is called a "Current Controller Device ".
The current controller device inputs the current signal, which isLow impedance input requires high driving power. For example, the bipolar transistor (BJT) is a current controller device, and the TTL circuit is a current controller device..
Q: What is a voltage controller?S: If the output parameter size of t
a low level. On the contrary, this method is especially used in interface circuits. To obtain a definite level, this method is generally used to ensure the correct circuit status to avoid accidents. For example, in motor control, the lower axle arm of the inverter bridge cannot be directly connected. If they are driven by the same single-chip microcomputer, the initial state must be set. Prevent passthrough!
