Abstract: An integrated circuit includes a first circuit, a second circuit, and a bus that couples the circuits together. The first circuit is simulated on a first simulator at the same time that the second circuit is simulated on a second simulator. A simulator plug-in is incorporated into the simulation model of the first circuit. A simulator plug-in is incorporated into the simulation model of the second circuit. If valid data is to pass from the first to second circuit across the bus during simulation, then the plug-in of the first model causes a network stack to generate a packet. The packet carries the data. After communication to the second simulator, the data is recovered from the packet, and is injected by the plug-in of the second model into the simulation of the second circuit. By exchanging data back and forth this way, multiple circuits are simulated simultaneously on different simulators.

Abstract: Software update information is communicated to a network appliance either across a network or from a local memory device. The software update information includes kernel data, application data, or indicator data. The network appliance includes a first storage device, a second storage device, an operating memory, a central processing unit (CPU), and a network adapter. First and second storage devices are persistent storage devices. In a first example, both kernel data and application data are updated in the network appliance in response to receiving the software update information. In a second example, only the kernel data is updated in the network appliance in response to receiving the software update information. In a third example, only the application data is updated in the network appliance in response to receiving the software update information. Indicator data included in the software update information determines the data to be updated in the network appliance.

Abstract: A device has physical network interface port through which a user can monitor and configure the device. A backend process and a virtual machine (VM) execute on a host operating system (OS). A front end user interface process executes on the VM, and is therefore compartmentalized in the VM. There is no front end user interface executing on the host OS outside the VM. The only management access channel into the device is via a first communication path through the physical network interface port, to the VM, up the VM's stack, and to the front end process. If the backend process is to be instructed to take an action, then the front end process forwards an application layer instruction to the backend process via a second communication path. The instruction passes down the VM stack, across a virtual secure network link, up the host stack, and to the backend process.

Abstract translation: 设备具有物理网络接口端口，用户可以通过该端口监视和配置设备。 后台进程和虚拟机（VM）在主机操作系统（OS）上执行。 前端用户界面进程在VM上执行，因此在VM中进行分区。 在VM外部的主机操作系统上没有执行前端用户界面。 设备中唯一的管理访问通道是通过物理网络接口端口，VM，VM堆栈以及前端进程的第一通信路径。 如果要指示后端进程采取行动，则前端进程通过第二通信路径将应用层指令转发到后端进程。 该指令通过虚拟机堆栈，跨虚拟安全网络链接，主机堆栈以及后端进程传递。
