tested after each modification.9. Fish and Paws can be combined, but not both (you can have your cake and eat it too–but not at once)We often meet with a rigid "or" choice. If we change our views and our system rules, these choices sometimes do not put us in a dilemma.? Experienced project managers know that increasing the number of system features and cutting time and expenses is not a good idea. However, this is possible if we refine our ideas, fin

required, so (40-2)/8 = 4.(4) timestamp option (timestamps)The timestamp option is used to calculate the round trip time RTT, where the sender sends the time value of the current clock into the timestamp field when sending the message segment, the receiver copies the value of the timestamp field into the acknowledgment message, and when the receiving party receives the acknowledgement message, compares the timestamp of the acknowledgment message (equal to the timestamp of the sender sending the

In addition, if you use Tcp_tw_reuse, you must set Tcp_timestamps=1, otherwise it is not valid. Here, you have to be aware that opening these two parameters will have a larger pit--may cause TCP to connect some weird problems (because, as mentioned above, if you do not wait for the timeout to reuse the connection, the new connecti

I don't know if anyone has played this way, maybe there is, maybe not.Time and space are always in the favoritism, only because the facilities are not complete, in the age of resource scarcity, can only choose. But if the resources are plentiful, the fish and bear paws can be fully combined! For a routing lookup, the compact data structure takes up a small amount of space, is it going to pay the price for it? If we consider the MMU facility, we will f

Another reason for ambiguity is that two names look much like each other. For example, "Thisisonename" and "thisisonname" difference between small and should not be seen at a glance. In addition, the lowercase L (l) and 1 are similar in some editors, and 0 and O are the same; Pay attention to this problem. There should be a clear distinction be
