road signaling and co-signaling. Signaling is a signaling network attached to a computer network or telephone network, do not need to re-build a network. The co-signaling system requires a re-construction of a signaling network (mainly between the offices).What is a signaling network?Signaling network is a special data support network which transmits signaling to the public channel signaling system.What constitutes a signaling network?Signaling networks are generally composed of signaling point

. Therefore, if the test results of Cat6A cables only pass the pass, the margin will be very tight. Of course, if you do not consider off-line crosstalk when using shielded cables, the margin is absolutely sufficient. 4. Test the transmission of a simulated data center network in Alien Crosstalk As you know, the cabling of twisted pair wires in the data center is very intensive. I have encountered a project with 960 copper cables in a cabinet. All the conclusions above are the results of theoret

includes multiple virtual machines, one virtual machine, multiple virtual machines, and other technologies. Through virtualization technology, you can manage multiple network devices in a unified manner, or completely isolate the services on one device, thus reducing the management cost of data centers by 40%, increase IT utilization by about 25%. 4. FCOE Technology Traditional data centers often have a data network and a storage network. The new generation of data center network convergence is

I always face a kind of problem, that is the technical staff always ask some magic word why is such, but not that, such as TCP's time-wait value is 2 minutes or 1 minutes, such as the STP timeout time is x instead of y ... Don't you know the perpetual motion? It is impossible for a machine to move without the input of energy from the outside. This is what I call Fulcrum theory, nothing can be justified, and everything needs outside influence. You see

, processing precision, directly related to the avoidance of link performance degradation and transceiver damage. In addition, the use of miniaturized optical fiber connectors (SFF) also improves the human interface of the traditional fiber interface. Two, high bandwidth IP application Multimedia Integrated cabling Today's network is moving towards centralization. The transmission of data, voice and video over a single medium can save a lot of money. STP
