Abstract: Computing devices and methods for transmitting and receiving optimized tunneling IP packets. At the entry point of a tunnel, an IP packet comprising at least one header is received. If data comprised in one of the at least one header of the received IP packet are redundant with data comprised in one or more tunneling header of a tunneling IP packet, then the redundant header is removed from the received IP packet. The tunneling IP packet encapsulating the received IP packet (with its redundant header removed) is transmitted. A header removal field is positioned in the tunneling IP packet to indicate the positive determination of redundancy. At the exit point of the tunnel, the tunneling IP packet is received. The header removal field and the one or more tunneling header of the tunneling IP packet are used for identifying the previous determination of redundancy and recreating the removed header.

In some embodiments, the method of operation of a network nodes comprises assigning POs to a plurality of User Equipments (UEs) in accordance with one or more anti-affinity groups such that, for a defined time interval, POs within the defined time interval are assigned to UEs in a same anti-affinity group. The method further comprises notifying the plurality of UEs of the POs assigned to the UEs. In this manner, the expected maximum number of pages within the defined time interval is substantially reduced.

Abstract: Preventing timeouts of I/O requests at a data storage system that are associated with cloud-based and/or external data storage systems. Rather than allow a timeout to occur, a response is sent to the host at a predetermined time before timeout, which will prevent the timeout from occurring and may cause the host system to “retry” the I/O operation by issuing another I/O request specifying the same I/O operation. The data storage system may repeat this process a preconfigured number of times or indefinitely, or until the host or user terminates or the application crashes. An I/O request received from a host may be configured in accordance with one or more SAN- or NAS-based protocols, and the I/O request may be translated into an I/O request conforming to one or more cloud-based and/or Internet-based protocols and transmitted to a cloud-based and/or external storage system.

The remote computing device further transmits an encrypted remote challenge. The local computing device generates a remote challenge response based on the remote challenge; and transmits an encrypted remote challenge response to the remote computing device.
