Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces on those devices. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases for simplicity, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

Abstract: Systems and methods for implementing network changes are described herein. In one aspect, a network change procedure may be comprised of a plurality of scripts that may implement a change in the network. In one embodiment, the deployment may be paused after the script has been executed. During the pause, a change management server may determine the impact of the change on the network. If the change had a positive effect, the change management server may execute another script to make another network change. However, if the change had a negative effect, the change management server may initiate one or more remedial actions.

Abstract translation: 本文描述了用于实现网络变化的系统和方法。 在一个方面，网络改变过程可以由可以实现网络改变的多个脚本组成。 在一个实施例中，可以在脚本被执行之后暂停部署。 在暂停期间，变更管理服务器可以确定改变对网络的影响。 如果更改有积极的作用，变更管理服务器可能会执行另一个脚本以使其他网络发生变化。 但是，如果更改产生负面影响，则变更管理服务器可能会启动一个或多个补救措施。
