Abstract: Systems and methods for SNMP access are disclosed. A computer-implemented method of SNMP access includes mapping a MIB object in a MIB into an XML object in an XML document, generating a class library based on the XML document, creating a service object representative of a service associated with SNMP access to the MIB object, and linking the class library according to the service object to perform the service.

Abstract: An anti-virus system for enforcing a virus monitoring and scanning process, the anti-virus and firewall system comprises a master CPU card, a plurality of slave CPU cards and a programmable logic. The master CPU card is used for controlling the virus monitoring and scanning process and dividing the virus monitoring and scanning process into a plurality of sub-processes. The plurality of slave CPU cards are controlled by the master CPU card in a software level and a hardware level, each of the plurality of slave CPU cards receives and processes one of the plurality of sub-processes then sends back to the master CPU card. The programmable logic controlled by the master CPU card for monitoring and controlling said plurality of slave CPU cards at a hardware level.
