Abstract: This application discloses a load balancing method and apparatus, and a device, and relates to the field of network technologies. The method includes: after a packet sent by a server is received, determining whether the packet is a first packet of a flowlet, if the packet is the first packet of the flowlet, determining a destination switch based on a destination address of the packet, determining a weight value of at least one equal-cost path associated with the destination switch in a stored equal-cost path weight table, where the equal-cost path weight table stores a correspondence between the at least one equal-cost path and the weight value, and scheduling, based on the weight value of the at least one equal-cost path, the packet onto a corresponding equal-cost path for transmission.

Abstract: A method and an apparatus are disclosed for generating an ACL table. 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.

Abstract: A method for obtaining a port path and an apparatus to improve a network capacity, where the method includes receiving, by a controller, a request message from a first server, where the request message requests port path information, and the port path information includes a port that a logical link from the first server to a second server passes through, obtaining, by the controller, a first absolute port path (APP) and a second APP according to network topology information, where the first APP includes a port that a logical link from a root node to the first server passes through, and the second APP includes a port that a logical link from the root node to the second server passes through, obtaining, by the controller, the port path information according to the first APP and the second APP, and sending the port path information to the first server.

Abstract: Embodiments of this application provide a transmission path determining method and apparatus, where the method includes: determining that a current path corresponding to a flow to which a to-be-transmitted packet belongs is congested; and determining a target path for the to-be-transmitted packet based on a path congestion information table, and adding information about the target path to the to-be-transmitted packet, so as to transmit the to-be-transmitted packet based on the target path, where a congestion degree of the target path is less than a congestion degree of the current path, each entry of the path congestion information table includes a transmission path and congestion information corresponding to the transmission path, and the congestion information is used to indicate a congestion degree of the transmission path.
