The segment list includes a plurality of sequentially arranged identifiers. The identifiers include a first-type identifier and a plurality of second-type identifiers. Network devices or links identified by the first-type identifier and the second-type identifier are respectively on the first network and a second network. A type of the first network is different from a type of the second network. The segment routing device encapsulates a second packet header for the first packet to form a second packet. The second packet header includes the plurality of second-type identifiers. The segment routing device sends the second packet to the second network.

Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for supporting a non-vector line. The method includes: selecting n non-vector lines TL from lines that are in an initializing stage, where n is an integer greater than or equal to 1; controlling to perform no further initializing for other lines that are in the initializing stage except the TL until the TL fully enters a data transmission stage; and before the TL enters the data transmission stage, estimating a far-end crosstalk coefficient CTL-SV from the TL to a vector line SV that is in the data transmission stage, where the CTL-SV is used in signal processing to eliminate far-end crosstalk caused by the TL to the SV.
Abstract translation: 本发明的实施例提供了一种用于支持非矢量线的方法，装置和系统。 该方法包括：从初始化阶段的线选择n个非向量线TL，其中n是大于或等于1的整数; 对TL以外的初始化阶段的其他行进行不进行初始化，直到TL完全进入数据传输阶段为止; 并且在TL进入数据发送阶段之前，从TL到估计远端串扰系数CTL-SV到在数据发送阶段的向量线SV，其中CTL-SV用于信号处理以消除远端串扰， 由TL引起的端到端串扰到SV。

Abstract: This application discloses a packet processing method and apparatus, and a computer storage medium, and belongs to the field of segment routing technologies. In the method, the network node receives a packet carrying an SRH, where the SRH includes one or more TLV fields and a TLV processing attribute, the TLV processing attribute indicates whether the network node needs to process the TLV fields included in the SRH, and the network node determines, based on the TLV processing attribute, processing of the TLV fields included in the SRH. In this way, any segment endpoint node on a segment routing network may determine the TLV processing attribute by using the SRH, so as to determine whether the TLV fields included in the SRH need to be processed.
