摘要： Methods, systems, and computer programs are presented for providing a program to a server. One method includes an operation for receiving a request by a switching device from a first server, the request being for a boot image for booting the first server. In addition, the method includes operations for determining if the boot image is available from non-volatile storage in the switching device, and for forwarding the request to a second server when the boot image is absent from the non-volatile storage. Further, the method includes an operation for sending the boot image to the first server from the switching device when the boot image is available from the non-volatile storage.

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.
