摘要： A computer readable medium that includes computer readable program code embodied therein. The computer readable medium causes the computer system to receive, by a data link rule enforcer, a packet from a packet source of the packets, and obtain a data link rule applying to a data link. The data link is operatively connected to the packet source, and the data link is associated with a media access control (MAC) address. The computer readable medium further causes the computer system to determine, by the data link rule enforcer, whether the packet complies with the data link rule, and drop, by the data link rule enforcer, the packet when the packet fails to comply with the data link rule.

摘要： A computing system is configured to receive incoming packets at a first priority designated for use when receiving packets that are not associated with specific subscription levels. Incoming packets are examined to determine whether they are associated with a particular subscription level. Responsive to a determination that a given packet received over a particular connection is associated with a particular subscription level, the computing system is reconfigured to process packets subsequently received over the same connection at a different priority associated with the particular subscription level.
