Abstract: A method is applied to a network comprising a first area and a second area. A first node in the first area obtains aggregated routing information, where the aggregated routing information is obtained by aggregating a plurality of pieces of original routing information, the plurality of pieces of original routing information correspond to N nodes in a network segment, the N nodes in the network segment have a same flexible algorithm flex-algo, and the aggregated routing information carries an algorithm identifier used to indicate the flex-algo and a network segment identifier used to indicate the network segment. The first node sends the aggregated routing information to the second area, where the aggregated routing information is used to indicate a node in the second area to send a packet to the N nodes in the network segment based on the aggregated routing information.

Abstract: A packet sending method and device. The first node sets a next-hop of the routing information to a next-hop through which the first node reaches the first route source. The destination address of the routing information is the address prefix. When the second route source is superior to the first route source, the first node switches the next-hop of the routing information to a next-hop through which the first node reaches the second route source. Then, the first node adds, to a target packet, path information of a forwarding path from the first node to the second route source according to the switching operation, where a destination address of the target packet matches the address prefix. Finally, the first node forwards the target packet to the second route source through the forwarding path.

Abstract: A method for performing bidirectional forwarding detection (BFD) on an aggregated link between a first network device and a second network device, where the first network device sends, to the second network device, information used to establish at least two BFD sessions. The first network device receives information that is used to establish at least two BFD sessions and sent by the second network device. The first network device respectively establishes BFD sessions between at least two pairs of ports according to the stored information and the information sent by the second network device. The first network device determines whether at least one BFD session in the established BFD sessions is up. If at least one BFD session in the established BFD sessions is up, the first network device determines that the aggregated link between the first network device and the second network device is available.

Abstract: A method, device, and system for measuring network packet loss. A sender performs data packet counting processing on a service stream sent to a receiver to obtain a first data packet count corresponding to a measurement period identifier. The sender sends an OAM packet including a measurement period identifier to be queried to the receiver. The OAM packet and a data packet of the service stream are transmitted on a same path. The sender receives a second data packet count that is returned by the receiver after the receiver receives the OAM packet. The second data packet count is a count obtained by the receiver by performing data packet counting processing on the received service stream. The sender determines a network packet loss situation according to the first data packet count and the second data packet count.
