Data structures

The main data structures using the various facilities of the program are in doubly linked list, which facilitates their movement. The maximum number of entries is limited only by available memory. Search operations in most of the facilities are carried out linearly, a fact that causes a mild but almost imperceptible impact. Because of the speed with which tends to increase the traffic monitor IPs, it use a

to perform searches more efficiently. (Search operations are carried out whenever the program needs to check if it is already listed the Ethernet or IP address or protocol or network port. In addition, it has a folding mechanism links merely contains notes on old entries that are available for reuse. Every time a connection is restarted or completely closed, the ticket information is not released, but added an entry to the ''closed-list.'' By detecting a new connection, the list is checked and if it is not empty, the first entry in use that is available will be reused, then, clear the ''list-closed''
