09836364 · 2017-12-05 · ·

Technology is disclosed for recovering I/O modules in a storage system using in-band alternate control path (ACP) architecture (“the technology”). The technology enables a storage server to transmit control commands, e.g., for recovering an I/O module, to the I/O module over a data path that is typically used to transmit data commands. The control commands are typically transmitted using ACP that is separate from the data path. By enabling transmission of control commands over the data path, the technology eliminates the need for separate medium for ACP, at least in part, to transmit the control commands. The technology can be implemented in a pure in-band ACP mode, which supports recovering an I/O module of a storage shelf in which at least one I/O module is responsive, and/or in a mixed in-band ACP mode, which supports recovery of I/O modules of a storage shelf in which all I/O modules are non-responsive.

Wi-Fi offload of cellular data

A security gateway system offloads cellular data from user equipment (“UE”). The system receives a dynamic host configuration protocol (“DHCP”) message from a Wi-Fi access point (“AP”) in communication with the UE. The system converts the DHCP message into an authentication, authorization and accounting (“AAA”) access request and sends the AAA access request to an AAA server. The system receives an AAA access accept from the AAA server and initiates a gateway general packet radio service tunneling protocol tunnel setup with a setup node.
