The present invention relates to the technical field of communications. Disclosed are a network operation and maintenance system and a method for same to be compatible with a change in a packet of a network management system. The method comprises: after an ASN packet sent by a network management system is received, acquiring the version of the network management system; then acquiring, according to the version, an identifier of a first ASN packet which has a field different from that of a corresponding standard ASN packet; and creating the first ASN packet, and processing a field value of the first ASN packet which is the same as that of the corresponding standard ASN packet in accordance with a processing flow which is the same as that of the standard ASN packet. Thus, only one system is needed to be automatically compatible with differences in packets of network management systems of different versions, which automatically completes docking during access to the network management system without user intervention, and acquires corresponding data. In addition, the technical solution of the present invention overcomes the deficiencies in the prior art that the system is difficult to maintain, manual intervention is needed, and a large amount of packets are redundant, without changing codes of any application layer processing the ASN packet. |
