  • Patent number: 10073971
    Abstract: Aspects of the subject disclosure are directed towards protecting machines, such as virtual machines in a cloud datacenter, from receiving unwanted traffic, and also reducing bandwidth by eliminating redundant data transmissions. In one aspect, an agent intercepts packets from a source, and determines whether the destination is allowed to receive packets from the source, based upon a communication group membership. The agent also may drop packets based upon malware/fraud signatures. The agent also attempts to reduce bandwidth by replacing redundant content with identifiers (e.g., hashcodes), which a destination machine uses to rebuild the original content. A destination-side agent may perform the same or similar communication group membership and malware/fraud signature filtering operations, and reassemble redundancy-reduced content from received identifiers as needed.

  • Patent number: 10069859
    Abstract: Some embodiments provide distributed rate limiting to combat network based attacks launched against a distributed platform or customers thereof. The distributed rate limiting involves graduated monitoring to identify when an attack expands beyond a single server to other servers operating from within the same distributed platform distribution point, and when the attack further expands from one distributed platform distribution point to other distribution points. Once request rates across the distributed platform distribution points exceed a global threshold, a first set of attack protections are invoked across the distributed platform. Should request rates increase or continue to exceed the threshold, additional attack protections can be invoked. Distributed rate limiting allows any server within the distributed platform to assume command and control over the graduated monitoring as well as escalating the response to any identified attack.

  • Patent number: 9451524
    Abstract: The broadcast nature of wireless communication may be utilized by transmitting a packet frame identifying at least one relay node that can transmit the packet frame without transmitting an acknowledgement frame confirming receipt of the packet frame by a respective relay node. A relay node may cancel a relay obligation to transmit a packet frame based on detecting transmission of the packet frame by another node or based on detection of an acknowledgement frame confirming that a destination node received the packet frame. A transmission chain corresponding to the transmission of a packet frame may be assigned a priority. Alternatively or in addition, a relay node within a transmission chain may be assigned a priority. A priority may determine the amount of delay inserted prior to transmitting a packet frame.

  • Patent number: 9419895
    Abstract: Techniques for customizing forwarding decisions in a network device via a hardware lookup table result are provided. In one embodiment, a network processor of the network device can perform a lookup into a lookup table based on one or more sections of a received packet. The network processor can then determine, based on the lookup, an entry in the lookup table and retrieve, using a pointer included in the lookup table entry, a mode value from a results table. The mode value can identify an operational flow (e.g., a series of forwarding decisions) to be carried out by the network processor for forwarding the received packet.

  • Patent number: 9344347
    Abstract: In a delay time measuring apparatus a sequence number, data length, and receiving time of a data packet transmitted from a source unit to a destination unit are stored in a storage section. In addition, an ACK number and receiving time of an ACK packet returned from the destination unit to the source unit are stored in the storage section. After that, a calculation section obtains an ACK packet an ACK number of which is equal to a value obtained by adding data length of a second data packet of two successive data packets transmitted without waiting for the ACK packet to a sequence number of the second data packet of the two successive data packets from the storage section. Then the calculation section calculates round trip time from receiving time of the second data packet of the two successive data packets and receiving time of the ACK packet obtained.
