    摘要: A digital clock placement engine has circuitry that adjusts a duty cycle of a clock signal and adjusts the locations of the rising/falling edges of the clock signal for purposes of data sampling or other operations. In a forwarded-clock interface implementation, a clock signal is received along with a data signal, and the received clock signal may be distorted to due various factors. To enable the received data signal to be sampled correctly, the clock placement engine generates a recovered clock signal having rising and falling edges that are placed/timed between the rising and falling edges of the received clock signal.

    摘要: Methods, systems, and computer readable media for offloading IPsec processing from application hosts using an IPsec proxy mechanism are disclosed. According to one method, at least one of unencrypted, IPsec, and Internet key exchange (IKE) packets transmitted between a first application host and a second application host are intercepted by a network gateway. The network gateway performs all IKE and IPsec-related processing for the at least one unencrypted, IPsec, and IKE packets on behalf of the first application host such that the second application host is unaware that IPsec processing is being performed by the network gateway.

    摘要: According to one aspect, the subject matter described herein includes a method for communicating an encrypted data packet. The method includes steps occurring at a first gateway node. The method also includes receiving a data packet from a first host. The method further includes determining that a first security association (SA) instance associated with the data packet is in an inactive state. The method further includes identifying a second SA instance that is both associated with the data packet and in an active state. The method further includes forwarding the data packet to the second SA instance.
