摘要： The present invention provides a method and apparatus for facilitating hot upgrades of software components within a telecommunications network device through the use of “signatures” generated by a signature generating program. After installation of a new software release within the network device, only those software components whose signatures do not match the signatures of corresponding and currently executing software components are upgraded. Signatures promote hot upgrades by identifying only those software components that need to be upgraded. Since signatures are automatically generated for each software component as part of putting together a new release a quick comparison of two signatures provides an accurate assurance that either the software component has changed or has not. Thus, signatures provide a quick, easy way to accurately determine the upgrade status of each software component.

摘要翻译： 本发明提供了一种通过使用由签名生成程序生成的“签名”来促进电信网络设备内的软件组件的热升级的方法和装置。 在网络设备中安装新的软件版本后，只有那些签名不符合相应和正在执行的软件组件的签名的软件组件才能升级。 签名通过仅识别需要升级的软件组件来促进热升级。 由于每个软件组件都会自动生成签名，作为组合新版本的一部分，两个签名的快速比较可以提供软件组件已更改或尚未更改的准确保证。 因此，签名提供了一种快速，简单的方法来准确地确定每个软件组件的升级状态。
