摘要： Embodiments of this application provide a communication method and an apparatus, and relate to the field of communication technologies, to resolve an existing technical problem that a packet forwarding delay is long when a packet is forwarded through a layer 2 network and a layer 3 network in an ethernet. The method includes: A first network device receives a service packet from a first endpoint device, where a destination MAC address of the service packet is a specific local MAC address of a second endpoint device, the specific local MAC address includes an indication prefix and location information, the indication prefix indicates that the specific local MAC address includes the location information, and the location information indicates an access location of an endpoint device in a network. The first network device determines an egress port from a preset routing table based on the location information in the specific local MAC address of the second endpoint device, and sends the service packet through the egress port, where the routing table includes the location information and the egress port corresponding to the location information.

摘要： This application discloses a congestion control method and apparatus. In this application, a network device obtains time information of one or more congestion packets in a sent first data stream, where the one or more congestion packet carries a flag indicating a congestion notification; when the first data stream is congested, obtains a first congestion notification packet based on the time information of the one or more congestion packets in the first data stream, where the first congestion notification packet notifies that a packet is congested beyond a first specified interval; and sends the first congestion notification packet. According to the solutions in this application, a rate of a data stream can be prevented from being increased when the data stream is congested, and packet transmission efficiency is improved.

摘要： The present invention discloses a method for avoiding congestion on a network device and a network device, in order to resolve a problem of a decrease in a throughput of a network device caused when the network device performs, after receiving a series of packets, packet discarding processing on the series of packets in a manner of randomly and discretely discarding packets. The method includes: determining, by a network device according to a size of currently used storage space, whether packet discarding processing needs to be performed on packets that belong to a same data flow in the currently used storage space, where there are N packets that belong to the same data flow, and N≥2; and if packet discarding processing needs to be performed, discarding, by the network device, continuous M packets that belong to the same data flow, where 1≤M≤N.

摘要： The present invention discloses a method, system and device for packet routing, and a method and system for choosing backup resources. The method for packet routing includes: updating busy levels of nodes at predetermined intervals; and choosing a packet receiving node according to a Distributed Hash Table (DHT) algorithm and the busy levels of nodes and sending a packet to the chosen packet receiving node. The system for packet routing includes a sending node and a routing node. The method for choosing backup resources includes: a state advertising node broadcasts the busy level of the local node to other nodes in one multicast group; and a backup resource choosing node chooses a proxy node according to the received busy levels of nodes. The system for choosing backup resources includes a state advertising node and a backup resource choosing node. With the present invention, a node chooses a packet receiving node with reference to the busy levels of nodes in its routing table, which balances the loads among the nodes and avoids the happening of network congestion.
