Abstract: A package substrate, including a first reference layer and a second reference layer disposed opposite to each other, a first composite layer disposed on a side of the first reference layer and close to the second reference layer, a second composite layer disposed on a side of the second reference layer and close to the first reference layer, and a metal trace is laminated between the first composite layer and the second composite layer. The first composite layer and the second composite layer each include a first dielectric layer and a second dielectric layer disposed opposite to and in contact with each other, the first dielectric layer is in contact with the metal trace, and a stiffness of the second dielectric layer is greater than a stiffness of the first dielectric layer.

Abstract: Embodiments of this application disclose a tunnel establishment method. A first communication apparatus may receive first adjacency topology information sent by a second communication apparatus, and establish a first tunnel between the first communication apparatus and the second communication apparatus when the first adjacency topology information matches second adjacency topology information of the first communication apparatus. It can be learned that, in this solution, the first communication apparatus may locally store only the second adjacency topology information of the first communication apparatus. Compared with the conventional technology in which information about two endpoints of a tunnel needs to be configured on the first communication apparatus, configuration for the first communication apparatus is simpler.
