    Abstract: Methods for managing an address on a switching device, managing an address on a network switch, and screening addresses in a cloud computing environment are provided. One embodiment is directed towards a computer-implemented method for managing an address on a switching device that is communicatively coupled to a plurality of virtual machines. The method includes accessing an address pool that includes an assigned address for each virtual machine from the plurality of virtual machines. The method includes determining, on the switching device, a used address for the virtual machine from the plurality of virtual machines. The method includes determining whether the used address is matching the assigned address for each virtual machine. The method also includes routing traffic from the virtual machine to a hypervisor in response to the used address matching the assigned address.

    Abstract: Some implementations of the present invention provide mechanisms for gating the transmission of FIN and other short overhead messages of the like in order to improve spectral efficiency. In some implementations spectral efficiency is improved by reducing the number of air-link connections established to merely transmit FIN and other short overhead messages of the like. In one implementation FIN messages are buffered in a queue and transmitted when an air-link connection is established to transmit higher value messages. In one implementation FIN messages are buffered and transmitted when the contents of the buffer breach a threshold that justifies the establishment of an air-link connection to transmit the contents of the buffer.

    Abstract: Approaches for preventing TCP data injection attacks in packet-switched networks are disclosed. A first approach provides for dropping received segments that carry ACK values smaller than the next unacknowledged sequence number expected minus the maximum window size. This approach helps keep spurious injected segments out of the TCP re-assembly buffer. In a second approach, heuristics are used to examine the sequence number of a newly arrived segment, and when the sequence number is the next expected, then the newly arrived segment is used and the contents of the re-assembly buffer are not considered. Further, if the data payload of the newly arrived segment overlaps in sequential order with segments already in the re-assembly buffer, the overlapped segments in the re-assembly buffer are considered spurious and are discarded. Thus, this approach helps remove spurious data from the re-assembly buffer if the first approach somehow fails to prevent the data from entering the re-assembly buffer.

A method for controlling bandwidth allocation of each of a plurality of data packet categories in a multi-rate network by determining, by a device, a throughput rate of one of a plurality of data packet categories/classes (the jth data packet category) and reducing the throughput rate of the jth data packet category when the throughput rate reaches a predetermined level, wherein a maximum bit rate of a data packet category is based on a distance between members of the data packet category and the device and wherein said jth data packet category transmits TCP packets, is described.
