摘要： A network node of a telecommunications network controlled by a link-state protocol includes a network interface which receives a message that contains information on a change in topology of the network. The node includes a processing unit that blocks forwarding of traffic to at least one neighbor node of the network at the network interface, agrees on the change in topology with the neighbor node; and unblocks the forwarding of traffic when the neighbor node has information about the topology which is the same as the information about the topology in a memory. A transient loop prevention method of a network node of a network having a plurality of a network nodes controlled by a link-state protocol includes the steps of receiving a message at a network interface which contains information on a change in topology of the network. There is the step of blocking forwarding of traffic to each neighbor node of the network at the network interface by a processing unit. There is the step of agreeing by the processing unit on the change in topology with the neighbor node. There is the step of unblocking the forwarding of traffic when the neighbor node has information about the topology which is the same as the information about the topology stored in a memory.

摘要： This application discloses an attack stream identification method, apparatus, and device on a software defined network, where the software defined network includes a switch and a controller, where an invalid stream filter table is stored in the switch, and the attack stream identification method includes the following steps: receiving, by the switch, a data packet of a data stream, and searching, according to a characteristic value of the data packet, the invalid stream filter table for a state field of a filter entry corresponding to the data stream; when the state field is a suspected attack stream state or a non-attack stream state, sending, by the switch, a report message to the controller; determining, by the switch, a rate value for sending the report message to the controller, and filling the rate value in a rate field of the filter entry; and when the rate value is greater than a preset rate threshold, changing, by the switch, the state field of the filter entry to an attack stream state. The foregoing solution prevents a broadcast storm caused by an attack stream, and reduces resource waste of a controller and a switch.

摘要： The present invention discloses a method, an apparatus and a system for determining a service transmission path. The method includes: receiving a service chaining object sent by a client based on an expanded path computation element communication protocol (PCEP), wherein the service chaining object contains service processing capacities which service nodes need to provide when transmitting a service in a network; determining at least one service node matched with the service chaining object in the network according to service processing capacities which service nodes in pre-stored service node attribute information are capable of providing; and generating a service transmission path based on the determined service nodes, for transmitting the service initiated by the client. The problems of large flow pressure and low utilization rate of the service nodes deployed in the network may be well solved.

摘要： Provided are a Transparent Interconnection of Lots of Links (TRILL) Intermediate System to Intermediate System (ISIS)-based route calculation method and device. The method includes that: a route calculation unit acquires a Link State Protocol Data Unit (LSP) packet from each Routing Bridge (RB) in a network (S102); and the route calculation unit calculates a routing table of each RB according to the LSP packet acquired from each RB, and sends the routing table to the corresponding RB (S104). The method solves the problem that a TRILL ISIS-based route calculation manner adopted in related technologies occupies considerable calculation resources and can be easily attacked. The method reduces the calculation resources occupied by the TRILL ISIS-based route calculation manner, and reduces the opportunities of attacking the TRILL ISIS since it is unnecessary in the present scheme to conduct mutual flooding and synchronization among various RB and save the LSP of other RB, thereby improving the stability and reliability of a system.
