    • A virtual machine operating system for communication between first and second applications which execute in different user portions of the virtual machine operating system and use Internet Protocol (IP). The virtual machine operating system comprises a first user portion, a second user portion and a base portion. The first user portion executes the first application and includes a first device driver for a first virtual network interface card (NIC). The second user portion executes the second application and includes a second device driver for a second virtual NIC. The base portion is shared by the first and second user portions and includes the first and second virtual NICs. The base portion maintains a table of IP addresses by which each device driver addresses its respective NIC and other, corresponding addresses by which the base portion addresses the virtual NIC. The first device driver is programmed to receive an IP datagram from the first application and pass it to the first NIC using IP. The datagram includes an IP address of the second virtual NIC and an indication that the second application should receive the datagram. The base portion is programmed to determine the other address of the second NIC based on the table and transfer the datagram to a storage location associated with the second virtual NIC or the second device driver.
    • 用于在虚拟机操作系统的不同用户部分中执行并使用因特网协议(IP)的第一和第二应用之间的通信的虚拟机操作系统。 虚拟机操作系统包括第一用户部分,第二用户部分和基本部分。 第一用户部分执行第一应用并且包括用于第一虚拟网络接口卡(NIC)的第一设备驱动器。 第二用户部分执行第二应用并且包括用于第二虚拟NIC的第二设备驱动程序。 基本部分由第一和第二用户部分共享,并且包括第一和第二虚拟NIC。 基本部分维护IP地址表,每个设备驱动器通过该表来寻址其各自的NIC以及基本部分通过该地址对虚拟NIC的其他对应的地址。 第一个设备驱动程序被编程为从第一个应用程序接收IP数据报,并使用IP将其传递到第一个NIC。 数据报包括第二虚拟NIC的IP地址和第二应用程序应该接收数据报的指示。 基本部分被编程为基于该表来确定第二NIC的另一个地址,并将数据报传送到与第二虚拟NIC或第二设备驱动程序相关联的存储位置。
