1. A Layer 2 measurement method, performed by a network side device, comprising:
obtaining a Layer 2 DownLink (DL) packet delay or a layer 2 UpLink (UL) packet delay, wherein the Layer 2 DL packet delay comprises;
D1 which is a delay of a packet transmitted through an interface between a Master Node (MN) and a Secondary Node (SN);
D2 which is a delay of a packet transmitted through an air interface between a Distributed Unit (DU) and a terminal;
D3 which is a delay of a packet transmitted through an interface between a Centralized Unit (CU) and a DU; and
D4 which is a delay a Packet Data Convergence Protocol Service Data Unit (PDCP SDU) transmitted in a CU User Plane (UP),
wherein the Layer 2 UL packet delay comprises:
the D1, the D2, and the D3.
