    • A network acceleration device includes a persistent, in-memory cache of network content. For example, the cache may store content in a manner that allows a software process to map virtual memory to specific, known regions of an underlying physical memory. Upon detecting a failure of a process executing within the network device, the network acceleration device may restart the software process and remap data structures of the cache to the known regions of the physical memory without necessarily requiring that the cache content be reloaded from a non-volatile memory, such as a hard drive. In this manner, the network acceleration device may accelerate download speeds by avoiding timely cache content restoration in the event of a software process failure.
    • 网络加速设备包括网络内容的永久性内存缓存。 例如,缓存可以以允许软件进程将虚拟存储器映射到底层物理存储器的特定的已知区域的方式存储内容。 在检测到在网络设备内执行的过程的故障时,网络加速设备可以重新开始软件处理并将高速缓存的数据结构重新映射到物理存储器的已知区域,而不一定要求高速缓冲存储器内容从非可读存储器重新加载, 易失性存储器,如硬盘驱动器。 以这种方式,网络加速设备可以通过在软件过程失败的情况下及时缓存内容恢复来加速下载速度。
