Abstract: Embodiments of this application provide a method for obtaining path information and an apparatus, relate to the communications field, and can accurately obtain a forwarding path for detecting a service packet. A service packet is obtained, where the service packet is a target service packet or an updated target service packet, the target service packet is a service packet that matches a flow rule, and the flow rules used to obtain the service packet that matches the flow rule; an ingress interface information field and/or an egress interface information field is/are generated according to a path detection tag on an ingress interface and/or an egress interface through which the service packet passes. The method is used to obtain path information of the service packet.

Abstract: The present disclosure discloses a flow specification (FlowSpec) message processing method. In the method, a controller forwards device interface information reported by the forwarding device; selects at least one forwarding device interface to which a FlowSpec rule needs to be applied from the received forwarding device interface information; generates an application interface rule based on the at least one forwarding device interface to which the FlowSpec rule needs to be applied; and sends a FlowSpec message to the forwarding device.

Abstract: A method for allocating a global label is provided, including: receiving, by a controller, a first message sent by a forwarding apparatus, where the first message carries a first label range, multiple labels included in the first label range are a subset of multiple labels included in a label space of the forwarding apparatus, and the first label range is not equal to the label space of the forwarding apparatus; and allocating, by the controller, a global label to the forwarding apparatus according to the first label range carried in the first message, where the global label is a label in the first label range. In addition, a method for obtaining a global label, a controller, and a forwarding apparatus are further provided. The foregoing solutions improve efficiency of global label allocation.
