A conformance testing method including: obtaining a testing symbol pattern in an optical signal; performing equalization compensation on the testing symbol pattern; generating a testing eye pattern; calculating a value of a first parameter based on the testing eye pattern and a noise enhancement coefficient, where the first parameter is used to determine a transmitter dispersion eye pattern closure degree of the optical transmitter; and when the value of the first parameter is less than or equal to a preset threshold, determining that conformance testing on the optical signal succeeds.

Conformance testing method and apparatus, and storage medium

Embodiments of this application provide a link resource transmission method and apparatus. The method includes the following steps. A first node floods first control routing information, where the first control routing information includes an identifier of an area in which the first node is located. A second node floods second control routing information, where the second control routing information includes an identifier of an area in which the second node is located. The first node determines, through comparison, whether the identifier of the area in which the first node is located is consistent with the identifier of the area in which the second node is located. When the identifier of the area in which the first node is located is consistent with the identifier of the area in which the second node is located, the first node transmits link data information of the first node to the second node.

Link resource transmission method and apparatus

The present invention discloses a switching apparatus, a switching apparatus group, a data transmission method, and a computer system, and pertains to the field of computer technologies. The switching apparatus includes: a selection circuit module, a SERDES module, and a scheduling module.
