Abstract:
A routing method and a device to provide a routing path that satisfies a quality of service (QoS) requirement, where the routing method includes performing QoS measurement on a path between the first routing node and a reachable adjacent routing node, to obtain a QoS parameter set of the path between every two adjacent routing nodes, reporting the QoS parameter set to the control node, receiving one or more routing tables of routing performed from the first routing node to the other routing node that are delivered by the control node, and receiving a packet, determining, from the one or more routing tables, a routing table corresponding to an identifier of the packet, and forwarding the received packet based on the routing table.
Abstract:
Embodiments of the present invention provide a method, a device, and a system for realizing disaster tolerance backup. The method includes the following steps: a device with an active-standby function determines a current state of the device with the active-standby function, after it is determined that the current state is an active state, the device with the active-standby function issues reachable route information to a connected routing device, where the device with the active-standby function and a device of which a current state is a standby state have a same IP address, the reachable route information includes route information relevant to the IP address, so that the IP address is reachable, and the device with the active-standby function and the device of which the current state is the standby state are backup devices for each other. The present invention can realize remote disaster tolerance backup and avoid service interruption.
Abstract:
An attack data packet processing method, an apparatus, and a system are provided. The method includes receiving, by a management node, description information of an attack data packet and an attack type of the attack data packet, where the description information and the attack type are sent by an awareness node; determining a processing policy on the attack data packet of the attack type according to the attack type; and sending the description information and the processing policy to a switch using a software-defined networking controller, so that the switch performs an operation indicated by the processing policy on the attack data packet with the description information.
Abstract:
A method for implementing a session border controller (SBC) pool and a SBC device are provided. In the present invention, an SBC pool is formed by at least two SBCs, the at least two SBCs are mutually backed up for disaster recovery and use a same Internet Protocol (IP) address for a terminal device, and whether the terminal device is registered in the SBC pool is determined; and if the terminal device has been registered in the SBC pool, a service message is forwarded to an SBC with which the terminal device is registered. In this way, it is avoided that SBC device disaster recovery places a special requirement for the terminal device, and the terminal device does not need to be configured with two IP addresses. Furthermore, all devices in the SBC pool can process the service message of the terminal device, thereby increasing a resource utilization rate.

Abstract:
A neural network model processing method includes obtaining a first low-bit neural network model through training, where the model includes a first operation layer and a second operation layer. Each operation layer includes at least one operation. Values/a value of a parameter and/or data used for the operation are/is represented by using N bits, and N is a positive integer less than 8. The neural network model processing method further includes compressing the model to obtain a second low-bit neural network model, where the compressed model includes a third operation layer. The third operation layer is equivalent to the first operation layer and the second operation layer, and an operation layer other than the third operation layer in the at least one operation layer is the same as an operation layer other than the first operation layer and the second operation layer in the at least two operation layers.
