Abstract: A packet scheduler and a packet scheduling method are provided to satisfy a fair transmission rate of system resources and wired/wireless resources of radio traffic by inducing a fair traffic jacket transmission. An RLC(Radio Link Control) packet scheduler of an RLC layer checks whether a bearer is a real time bearer or a non-real time bearer(S100). If the bearer is a real time bearer, the RLC packet scheduler calculates a virtual scheduling time(S200). In the case of the non-real time bearer, the RLC packet scheduler calculates the virtual scheduling time by using another mathematic formula(S300). The RLC packet scheduler preferentially transmits a packet of a bearer having the largest virtual scheduling time to a MAC(Medium Access Control) layer by using the calculated virtual scheduling time(S400).

Abstract: A system and a method for detecting web application attacks by using a web log correlation analysis are provided to detect unknown attacks according as determining whether an access to a specific web page is normal or not, and to reduce false positive rate. A system for detecting web application attacks includes a web log preprocessor(110), a web log database(120), a web log correlation unit(130), and a correlation analysis information database(133). The web log preprocessor converts log information stored at a web log into formatted web log, constructs the formatted web log in a formatted log and stores the formatted web log at the web log database. The formatted web log stored at the web log database is transferred to a web log correlation unit. The web log correlation unit, including a connection state analysis unit(131) and a similarity measurement unit(132), calls the formatted web log, analyzes the formatted web log, and detects an intrusion with respect to a client request by using the analysis result. The connection state analysis unit manages site topology information, namely detects an abnormal access to a site by maintaining information on a state of connection between web pages. The connection state analysis unit determines an abnormal access or not by using a status code of the formatted web log in the formatted log table. Then, the connection state analysis unit stores a query string of a user to the correlation analysis information database in case of determining that an access to the web site is abnormal. The similarity measurement unit checks whether there exists string similar to query string of an attacker at the correlation analysis information database by calculating similarity of the query string of the attacker on the basis of the Ratcliff pattern matching algorithm.
