    • Methods implemented in an electronic device are disclosed for checkpoint and rollback recovery in a SDN system. The method utilizes message identifiers to indicate an order of consistent states of forwarding tables of a plurality of network elements of the SDN system. The SDN controller of the SDN system receives a request to recover the network to a previous state, and identifies a consistent state of forwarding table for each of the plurality of network elements utilizing the message identifiers associated the consistent states, where the identified consistent states represent the previous state of the network without the identified consistent states being captured at the same time at the plurality of network elements. The SDN controller indicates the identified consistent state for each of the plurality of the network elements to a corresponding network element, where the corresponding network element makes its forwarding table consistent with the identified consistent state.
    • 公开了一种在电子设备中实现的方法,用于SDN系统中的检查点和回滚恢复。 该方法利用消息标识符来指示SDN系统的多个网络元件的转发表的一致状态的顺序。 SDN系统的SDN控制器接收到将网络恢复到先前状态的请求,并且使用与一致状态相关联的消息标识符来识别多个网络元件中的每一个的转发表的一致状态,其中所标识的一致状态表示 在多个网络元件处同时捕获没有识别的一致状态的网络的先前状态。 SDN控制器将所识别的多个网络单元的一致状态指示给相应的网络单元,其中相应的网络单元使其转发表与所识别的一致状态一致。

    • A method of managing network configuration data in a database includes storing current configuration data representing a current configuration of the network in a database as a collection of managed objects. Historical configuration data representing past configurations of the network is stored in the database as a collection of changed objects. Change parameters associated with the changes to the configuration data may additionally be stored. The database may be restored to a prior version, representing a prior configuration of the network, by restoring at least one changed object. The database may be altered to other configurations by restoring one or more changed objects. The changed objects to be restored may be selected by change parameters, such as a timestamp, operator identification, or group code. Proposed changes to the network may be modeled by substituting proposed configuration data for the current configuration data in the database.
    • 管理数据库中的网络配置数据的方法包括将表示网络的当前配置的当前配置数据存储在数据库中作为被管理对象的集合。 表示网络过去配置的历史配置数据作为已更改对象的集合存储在数据库中。 可以另外存储与配置数据的更改相关联的更改参数。 通过恢复至少一个改变的对象,可以将数据库恢复到表示网络的先前配置的先前版本。 可以通过恢复一个或多个改变的对象来将数据库改变为其他配置。 可以通过更改参数(例如时间戳,操作员标识或组代码)来选择要恢复的更改对象。 可以通过将建议的配置数据替换为数据库中的当前配置数据来建模对网络的更改。
