Abstract: Example service processing methods and apparatus are described. One example method includes obtaining a service template set by a first controller. The service template set includes one or more service templates. The first controller sends service template information corresponding to the service template set to a second controller. The first controller receives a first message sent by the second controller. The first message includes first service template information corresponding to a first service template, and the first service template information is determined by the second controller according to a requirement of a first service. The first controller performs provisioning of the first service based on the first service template that is determined based on the first service template information. The second controller determines a corresponding service template according to a service requirement, to trigger the first controller to perform service provisioning based on the service template.

Abstract: This application discloses a method for identifying a source address of a packet and an apparatus, and pertains to the field of network security. A protecting device intercepts a packet whose destination address is an IP address of a protected device, where the protected device provides a service according to the QUIC protocol. The protecting device sends a retry packet to a source address of the packet in response to that the packet is an initial packet. The protecting device identifies the source address of the packet as an attack source address if the protecting device receives no response packet corresponding to the retry packet. The protecting device determines the source address of the intercepted initial packet to identify an attack source address used by an attacker, and subsequently prevents only packets from the attack source address from being sent to the protected device.
