Extending acceptable sequence range

A sequence recovery method performed by a node in a time sensitive network, the method comprising: receiving a packet having a sequence number; determining whether the sequence number is within a predetermined range of reference sequence numbers, where the reference sequence number is a current latest sequence number accepted by the node, and where the predetermined range includes a historical range and a future range, wherein the historical range has a length equal to a historical length and includes the reference sequence number and a predetermined number of consecutive sequence numbers immediately before the reference sequence number, and the future range has a length equal to a future length and defines a predetermined number of consecutive sequence numbers immediately after the reference sequence number, wherein the future length is greater than the historical length. 一种由时间敏感网络中的节点执行的序列恢复方法，所述方法包括：接收具有序列号的分组；确定所述序列号是否在参考序列号的预定范围内，其中所述参考序列号是所述节点接受的当前最新序列号，并且其中所述预定范围包括历史范围和未来范围，其中所述历史范围具有等于历史长度的长度并且包括所述参考序
