This application provides a BIER multicast traffic statistics collection method, a device, and a system. The method includes: A first network device obtains a first BIER packet. The first network device performs traffic statistics collection on the first BIER packet based on multicast flow information, to obtain a traffic statistics collection result of the first BIER packet, where the multicast flow information is used to identify a multicast flow to which the first BIER packet belongs. The first network device sends the multicast flow information and the traffic statistics collection result of the first BIER packet to a controller.

The present disclosure provides a serial port communication mode conversion method, system, and circuit for a serial port circuit, in which the serial port circuit includes a first serial port and a second serial port, a transmission signal line of the first serial port and a reception signal line of the second serial port are connected to form a half-duplex signal line. The method includes: configuring the second serial port to enable after a preset time; controlling the first serial port to transmit a control signal to an external device through the half-duplex signal line within the preset time; and controlling the second serial port to receive response data transmitted by the external device through the half-duplex signal line after the preset time. The present disclosure realizes the conversion of the full-duplex serial port to the half-duplex serial port.

A method and network device for distributing Multi-Protocol Label Switching (MPLS) labels are provided by the present invention. The method for distributing the MPLS labels includes: a first device receives a Border Gateway Protocol (BGP) protocol message transmitted from a second device, wherein the BGP protocol message carries a service identifier of the second device; the first device establishes, according to the service identifier of the first device and the service identifier of the second device, a corresponding relationship between the first device and the second device; the first device distributes a MPLS label for the corresponding relationship. The present invention realizes that the MPLS labels are distributed for some type of the specific logical relationship between the two nodes in the BGP protocol, so that the network devices running the BGP protocol can efficiently obtain the MPLS label corresponding to the specific logical relationship.

Embodiments of the present invention provide a network label allocation method, a device, and a system, which enable a local PE to distinguish packets from different remote PEs. The method includes: generating, by a local provider edge PE, a VPN label route for each remote PE, where VPN labels in VPN label routes of different remote PEs are different, and the remote PE and the local PE at least belong to a same VPN; and sending the VPN label route to the remote PE, so that the remote PE separately matches an IP address of the remote PE with a target device IP address in the VPN label route, and matches an import route target RT of each VRF of the remote PE with a route target RT in the VPN label route, a packet related to a successfully matched VRF.
