摘要： A packet tunneling method, a switching device, and a control device are provided. The method includes: receiving, by the switching device, a tunnel flow table entry delivered by the control device, where the tunnel flow table entry is used to determine a to-be-tunneled packet and indicate a tunneling operation to be performed on the to-be-tunneled packet; determining, by the switching device according to the tunnel flow table entry, whether the received first packet is the to-be-tunneled packet; and when the first packet is the to-be-tunneled packet, tunneling, by the switching device, the first packet according to the tunnel flow table entry. According to the embodiments of the present invention, because the switching device supports a tunnel flow table, when a packet is transmitted in a mobile packet network by using the OpenFlow protocol, tunnel encapsulation or decapsulation can be performed on the packet by using the tunnel flow table entry delivered by the control device, thereby enhancing a packet processing capability in the mobile packet network.

摘要： One embodiment of the present invention provides a switch. The switch includes a packet processor and a spanning tree management module. The packet processor obtains information associated with a spanning tree from a message. The spanning tree management module, in response to the obtained information being superior to locally available information of the spanning tree, determines the port role of a local port of the switch for the spanning tree to be the root port and the port state of the local port for the spanning tree to be blocking.

摘要： The invention relates to a method and a bus system for the interchange of device-specific data between fieldbus slaves (FBS) of a first fieldbus (FB1) and a fieldbus master (FBM) of a second fieldbus (FB2), wherein the first fieldbus (FB1) is connected for communication to a common Ethernet network (EN) via a first gateway (G1) and the second fieldbus (FB2) is connected for communication to a common Ethernet network (EB) via a second gateway (G2), wherein the communication via the Ethernet network (EN) occurs according to the client-server communication principle, wherein the first gateway (G1) reacts on the network side as a fieldbus master (FBM) and on the Ethernet side as a web service server (WSS), and wherein the second gateway (G2) reacts on the fieldbus side as a fieldbus slave (FBS) and on the Ethernet side as a web service client (WSC). In order to accelerate the transmission of data between spatially separate fieldbuses and to reduce the data volume, according to the invention the fieldbus slaves (FBS) and the data thereof are configured in a database (DB) of the web service client (WSC), the web service client (WSC) transmits a list of required data to the web service server (WSS), and the web service server (WSS) cyclically extracts the required data from the fieldbus slaves (FBS) and returns only changes in data values to the web service client (WSC), wherein the database (DB) is updated in the web service client (WSC) on the basis of the changed data values.

摘要： A method and apparatus for flushing port tables in an Ethernet network that includes a Root Bridge node (1) and a plurality of bridge nodes (2-7). A ring of bridge nodes affected by a change in the topology of the Ethernet network is identified from the plurality of, bridge nodes. The ring of bridge nodes (2-7) includes a branching bridge node (2) providing a connection to the Root Bridge node (1). Port tables are flushed only at the bridge nodes on the ring (2-7), rather than all of the bridge nodes in the Ethernet network, which greatly reduces the amount of signalling required during a relearning process.
