    • A system, apparatus and a method for implementing a secured communications link at a layer other than that at which packets are filtered are disclosed. In one embodiment, a computer system is configured to form a virtual private network (“VPN”) and comprises an address inspection driver to identify initial target packet traffic addressed to a target server. Also, the computer system includes a pseudo server module to receive rerouted initial target packet traffic from the address inspection driver. The pseudo server module is configured to convey packet regeneration instructions to a VPN gateway. The address inspection driver functions to identify additional target packet traffic addressed to the target server and routes the additional target packet traffic to the pseudo server. In one embodiment, the pseudo server is configured to strip header information from the additional target packet traffic to form a payload, and thereafter, to route the payload to the target.

    • A method and system is provided for migrating processes from one virtual machine to another on a network. To migrate the external state of a process, the process may use a network service connection system or a compact network service connection system for accessing resources external to the virtual machine. A process may be migratable separately from other processes. A process may have an in-memory heap used for the execution of the process, a virtual heap that may include the entire heap of the process including at least a portion of the runtime environment, and a persistent heap where the virtual heap may be checkpointed. In one embodiment, the virtual heap may serve as the persistent heap. In another embodiment, the virtual heap may be checkpointed to a separate, distinct persistent heap. The combination of the in-memory heap, the virtual heap, and the persistent store may be referred to as a virtual persistent heap. One embodiment of a method for migrating an application may include checkpointing the application to a persistent heap. Current leases to local and/or remote resources may be expired. The persistent state of the process may be packaged in the persistent heap and sent to the node where the process is to migrate. A transaction mechanism may be used, where the process's persistent state is copied and committed as having migrated on both the sending and receiving nodes. The state of the process may then be reconstituted into a new virtual persistent heap on the node where the application migrated. Leases to local and/or remote resources for the process may be re-established. The process may then resume execution on the node where it migrated. In one embodiment, a versioning mechanism may be used whereby nodes where a process once lived may cache a previous state. In addition, a user interface (UI) may be provided to manage process checkpoints.
    • 提供了一种方法和系统,用于将进程从网络上的一个虚拟机迁移到另一个虚拟机。 为了迁移进程的外部状态,该进程可以使用网络服务连接系统或紧凑的网络服务连接系统来访问虚拟机外部的资源。 进程可以与其他进程分开移植。 进程可以具有用于执行进程的内存堆,可以包括进程的整个堆的虚拟堆,其中包括运行时环境的至少一部分,以及可以检查点的虚拟堆的持久堆 。 在一个实施例中,虚拟堆可以用作持久堆。 在另一个实施例中,虚拟堆可以被检查点到单独的,不同的持久堆。 内存堆,虚拟堆和持久存储的组合可以被称为虚拟持久堆。 用于迁移应用的方法的一个实施例可以包括将应用程序检查点定位到持久堆栈。 当地和/或远程资源的租赁可能已过期。 进程的持久状态可以打包在持久堆中,并发送到进程要迁移的节点。 可以使用事务机制,其中进程的持久状态被复制并提交为在发送节点和接收节点上进行迁移。 然后可以将进程的状态重新构建到应用程序迁移的节点上的新的虚拟持久堆中。 可以重新建立对该过程的本地和/或远程资源的租赁。 然后,进程可以在迁移的节点上恢复执行。 在一个实施例中,可以使用版本控制机制,其中过程曾经存在的节点可以缓存先前的状态。 此外,可以提供用户界面(UI)来管理过程检查点。
