Through above-mentioned processing procedure; Can obtain monitoring result to monitoring to the legitimacy of the operation of interface and operating process in the data link layer; Monitoring result and predetermined operations rule compared obtain fault message, thereby can position to high efficient and reliable the fault in the data link layer.
(2), be directed against the detection of message transmissions
The legitimacy of step 1, detecting operation;
When the operation to the data link layer message transmission is triggered; Startup is to the monitoring of the operation of data link layer message transmission; Message monitoring modular 312 obtains the type identification (for example send message identification or receive message identification) of interface operation requested operation; And the type is identified at operating database 32 matees (the action type sign that is about to enumerate in the action type field in operation types sign and the operating database 32 compares coupling); If comprise this operation types sign in the operating database 32, explain that then this operation is legal operation, create a new record as operation note according to data structure as shown in Figure 5; This operation types sign of the 8th to 15 bit record in operation note handles proceeding to step 2; If do not comprise this operation types sign in the operating database 32; Explain that then this operation is illegal operation; Create a new record as operation note according to data structure as shown in Figure 5 equally; At the 0th to the 1st of operation note record 00 expression operation failure, this operation types sign of the 8th to 15 bit record, in the abnormal results information (being specially the illegal information of action type) of the legitimacy of the 25th to 31 bit record monitoring operation, handle proceeding to step 4;
The legitimacy of step 2, detecting operation object
Whether legal the legitimacy of detection messages attribute comprises two aspects, comprise the consistency of the type of detection messages and detection messages self information;
At first; Message monitoring modular 312 obtains the type identification of message from the message of transmission; The type identification of the message that obtains is mated in operating database 32; The type of message sign of enumerating in the type identification that is about to message and the type of message field in the operating database 32 compares coupling, and with the type of message field that limits in the sign of the type of message of forbidding enumerated compare coupling, if the type of message field comprises the type identification of this message in the operating database 32; The type that this message is described is legal; The the 32nd to 55 bit in the operation note of having created continues the type identification of recorded message, otherwise the type of message is illegal;
Secondly, under the legal situation of the type of message, the consistency of detection messages self information; Particularly; From message, resolve length information and the address information (comprising source IP address, source MAC, purpose IP address and target MAC (Media Access Control) address) of obtaining message; Actual length and the address information of the length information of the message that parsing is obtained and address information and message compares, at this two all under situation of unanimity, the self information that message is described is consistent; If there is inconsistent situation in the two, explain that the message self information is inconsistent;
Under the consistent situation of legal and message self information, handle proceeding to step 3 in the type of message; Under the illegal perhaps inconsistent situation of message self information of the type of message; The the 0th to the 1st record 00 in the operation note of having created represented operation failure, write down the abnormal results information (being specially the illegal information or the inconsistent information of message self information of type of message) of the legitimacy of monitoring operand and the type identification that the 32nd to 55 bit continues recorded message at the 25th to 31 bit, handles proceeding to step 4;
The process of step 3, monitoring operation
The operating process of message monitoring modular 312 Monitoring Data link layer message transmissions; Particularly; Beginning message transmission when (comprise and begin to send message and begin to receive message); The the 16th to 17 sign that recording operation begins 00 in the above-mentioned operation note of having created, when finishing (comprise and finish to send message and finish to receive message) at message transmission, the sign 11 that finishes at the 16th to 17 recording operation of operation note.
And; Whether there are abnormal conditions in the process of message monitoring modular 312 monitoring message transmissions; When appearance is unusual in message transmission procedure; Message monitoring modular 312 obtains the abnormal information that business module produces according to concrete abnormal case, the abnormal information of obtaining is recorded in the 25th to 31 bit in the operation note of having created, and writes down 10 or 01 at the 0th to 1 bit of operation note;
For occurring when unusual, 0th to 1 bit record 11 signs of message monitoring modular 312 in the operation note of having created are operated successfully in message transmission procedure;
