: 4mbps= transmits 4M bits per second.　　The unit of data transfer rate, the letter B (bit) is the bit and the letter B (Byte) is a byte. 4. Throughput vs. Bandwidth: Throughput and bandwidth are easy to mix, and the units are Mbps. First let's look at the two corresponding English, throughput: throughput; Bandwidth: Max net bitrate. When we discuss the bandwidth of a communication link, it usually refers to the number of bits per second that the link can transmit. We can say that the bandwidth o

encoding in the computer network, also known as the line speed. It can be said that the bandwidth of Ethernet is 10Mbps. However, you need to differentiate between the available bandwidth (bandwidth) on the link and the number of bits (throughput) that can be transmitted per second in the actual link. It is generally more likely to use the term "throughput" to represent the test performance of a system. Thus, because the implementation is affected by

think it has been sent successfully. Because the signal propagation is time-delay, it also takes a while to detect the conflict. This is also why there must be a minimum frame length limit.by standard, 10Mbps Ethernet with repeaters, the maximum length of the connection is 2500 meters, up to 4 repeaters, so the minimum transmission time for a frame of 10Mbps Ethernet is 51.2 microseconds. The data that can

Replace the browser (using Firefox/firefox, Google/chrome, or other browsers) to try again, if still not online, try to change the computer to do a comparative test. Household network cable due to aging, poor quality or too long line, resulting in line attenuation is too large, resulting in a WAN port parameters, but not the Internet. Try to adjust the speed and duplex mode of the router's WAN

Therefore, please ensure that sufficient bandwidth is included for these services. In general, an Internet connection arrives at a router, and then the network adapter connects the computer to the router. You need a high-performance network card to prevent bottlenecks between Internet connections and computers. For example, i

wiring must pay special attention to distinguish the type of cable. Cable use does not meet the requirements will be the problem of network impassability.

packet is transferred first-to-first, which is common in the packet-switched network, and only when all the packets that have been reached are transferred, the packets just arrived can be transferred. The length of the packet is represented by the L-bit, and the link transfer rate from router A to Router B is represented by R bps (that is, b/s). For example, for a 10Mbps Ethernet link, the rate is r=10mbps

After comprehensive consideration, the basic is on the basis of live555 based on the development, in the optimization of the Live555 itself and the program internal video data transmission optimization, not only to achieve the

I, Ethernet IIEthernet Type II Ethernet frames have a minimum length of 64 bytes (6+6+2+46+4) and a maximum length of 1518 bytes (6+6+2+1500+4). The first 12 bytes respectively identify the source node MAC address of the sending data frame and the destination node MAC address of the receiving data frame.The next 2 bytes identify the upper-layer data type that is carried by the Ethernet frame, such as 16 binary 0x0800 representing the IP protocol data, 16 binary 0X86DD representing the IPV6 proto

frame transmitted by host a transmits to the first moment of B. Thus, when A's frame reaches B, b detects a conflict and sends a conflict signal. If A's frame has already been sent before the conflict signal in B is transmitted to a, then a will not detect the conflict and mistakenly think it has been sent successfully. Because the signal propagation is time-delay, it also takes a while to detect the conflict. This is also why there must be a minimum frame length limit.by standard,

Can effectively isolate broadcast storms, reduce the occurrence of packet errors and errors, and avoid sharing conflicts.The switch can transmit data between multiple port pairs at the same time.Each port can be treated as a separate network segment. The network device on which it is connected has all the bandwidth on its own. It is not nec

cost of 19 For a 10Mbps link, it has a port cost of 100 For Switch B There are two ports, Port 1/1 has a port cost of 19, Port 1/2 has a port cost of 38, so port 1/1 is the root port. Port 1/1 on Switch C has a port cost of 19 and Port 1/2 has a port cost of 38, so ports 1/1 is also the root port.If the Ethernet line between switch A and switch C is changed to 10Mbps, then the situation is differe
