Abstract: There is provided a method for optimizing a download of requested data to an electronic data processing unit that is currently receiving unrequested multicast data through a router included in a network. The unrequested multicast data corresponds to at least one multicast data group. Internet Group Management Protocol (IGMP) V2 Leave Messages are sent to the router for the at least one multicast data group. IGMP Membership Queries issued by the router for the at least one multicast data group are ignored, so as to cause the router to terminate a transmission of the unrequested multicast data to free up available bandwidth for the download of the requested data.

Abstract: A system and method for initializing a SNMP agent in SNMPv3 mode. In one aspect of the invention, a method is provided that allows an operator to securely enter the initial SNMPv3 privacy and authentication keys into a SNMPv3 device and cause the device to enter in SNMPv3 mode. The SNMP manager and SNMP agent both generate an associated random number and public value. The SNMP manager passes its public value to the SNMP agent in a configuration file, which causes a proprietary MIB element in the SNMPv3 device to be set with the public value of the SNMP manager. The SNMP manager reads the public value of the SNMP agent through a SNMP request using an initial valid user having access to the public value of the SNMP agent. The SNMP agent and SNMP manager each independently compute a shared secret using the Diffie-Hellman key exchange protocol.
