Abstract: In a network congestion handling method, a first network device determines a target port, where the target port is an egress port that is in a pre-congestion state or a congestion state. The first network device sends a first notification to at least one second network device. The at least one second network device is capable of sending, through at least two forwarding paths, a data flow to a host corresponding to the target port. The first notification includes information of a network device to which the target port belongs and information of the target port. The first notification can enable the at least one second network device to perform an operation of avoiding network congestion. The network congestion handling method can effectively alleviate network congestion and improve network bandwidth utilization.

Abstract: The present disclosure discloses a method and an apparatus for generating an ACL table, and relates to the data center field. A controller obtains a port type of each port of a first network device, and selects, based on the port type of each port, a target port whose port type is a preset type from all ports of the first network device. The controller generates a corresponding first-type access control list ACL entry for each target port, and generates one second-type ACL entry corresponding to a routing table of the first network device, where an action of the second-type ACL entry is redirecting to the routing table. The controller adds the second-type ACL entry and each first-type ACL entry to an ACL table of the first network device.
