Code as above; Write three functions of order500, order200 and orderNormal respectively, and process their own business logic in the functions respectively. If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.
That is to say, a total of false syn messages will occupy the TCP preparation queue for 63s, while the semi-connected queue defaults to 1024, which is different by system default and can be viewed by cat/proc/sys/net/ipv4/tcp_max_syn_backlog c. That is to say, sending 200 fake syn packets per second without any protection is enough to burst the semi-connection queue, thus preventing the real connection from being established and responding to normal requests. The end result is that the server has no time to ignore the normal connection request-denial of service.
