Abstract: A network performance parameter sending method includes: obtaining, by a first network node, a segment identifier of a second network node in a segment list of a packet, where the second network node is a next-hop segment node of the first network node on a forwarding path of the packet; and adding, by the first network node, a network performance parameter of the first network node to the segment list, and then sending the packet to the second network node. In a process of forwarding the packet by using the segment list in the packet, the first network node uses the segment list to carry the network performance parameter of the network node.

Abstract: Embodiments of the present invention provide a method, and an apparatus 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: Embodiments of the present invention relate to the field of communications and disclose a method and an apparatus for grouping line pairs, and a system, to solve a problem that obtaining a crosstalk cancellation coefficient matrix through channel training imposes a very high requirement on a system capability such as a computing capability and a storage capability and even affects user experience due to the relatively large number of line pairs in a large scale Vectored-DSL system. A technical solution provided in the present invention includes: acquiring crosstalk impact data between line pairs in a vectored-digital subscriber line Vectored-DSL system; and grouping line pairs, between which a crosstalk impact cannot be ignored, into one vector group according to a set threshold and the crosstalk impact data between the line pairs. The method and apparatus provided in the embodiments of the present invention are applicable to a large scale Vectored-DSL.
