摘要： A method for protecting against link failures in a communications network having a plurality of paths between senders and receivers is provided. The method includes sending data units by the senders over the communications network on working circuits, applying network coding to form a combination of data units from data units from a plurality of the senders, and sending the combination of data units over the communications network on a backup circuit. If one or more link failures occur in the working circuits resulting in loss of one or more of the data units, then the method further includes recovering the one or more of the data units from the combination of data units transmitted on the backup circuit. The backup circuit used to carry the combination of data units may be implemented in-band with user data or may be implemented as out-of-band backup circuits.

摘要： A method and system for providing protection of multiple communication sessions using the bandwidth resources on the order of those required to protect a single communication session. This is facilitated through the use of network coding on a protection cycle. Transmissions from all connections are coded together using network coding and transmitted in two different directions on a cycle, so that the signal can be recovered by the receiver in two ways: on the working path, and on the protection (cycle) path.
摘要翻译：一种方法和系统，用于根据保护单个通信会话所需的顺序的带宽资源提供对多个通信会话的保护。这通过在保护周期上使用网络编码来实现。所有连接的传输都使用网络编码一起编码，并在一个周期内以两个不同的方向进行传输，从而可以通过两种方式在接收机上恢复信号：工作路径和保护（循环）路径。
