Abstract: A method and apparatus for controlling link aggregation are provided. When a transmission path for transmitting data is established, it is detected whether an available bandwidth of a bearer link at a destination end of the transmission path to be established is sufficient for bearing the data to be transmitted. If not, it is determined whether the destination end has sufficient available aggregatable Ethernet links for bearing the data to be transmitted. If the destination end has sufficient available aggregatable Ethernet links for bearing the data to be transmitted, the destination end is notified to perform a link aggregation sufficient for bearing the data to be transmitted.

Abstract: A method, system, and apparatus for diagnosing a route in a network based on a Diameter protocol are provided. The method includes the following steps. A source Diameter node generates a diagnosis message and sends it. An intermediate Diameter node adds diagnosis information thereof to the diagnosis message after receiving it and forwards it until the diagnosis message is forwarded to a Diameter server capable of processing the diagnosis message or a Diameter node incapable of forwarding the diagnosis message. The Diameter server or the Diameter node generates a response message and sends it carrying diagnosis information thereof, information in the diagnosis message, and a response type. The intermediate Diameter node adds the diagnosis information thereof to the response message after receiving it, and forwards it until the response message is forwarded to the source Diameter node. The source Diameter node parses the response message to obtain route related information.

Abstract: A server, a P2P network system, a method for routing, and a method for transferring resource key assignment are provided. The server comprises a routing processing module and a storage module connected therewith. The P2P network system comprises a structured P2P network and a server configured therein. The server routes the searching node to the node storing the resource key assignment based on the stored information, to thereby achieve a quick route. The method for routing is realized by searching for the node storing the resource key assignment via the server. Therefore, it merely takes two hops, i.e., the server and the node storing the resource key assignment, for the node to find the resource key assignment in search.

Abstract: A method for generating a secure association key (SAK), a method for realizing medium access control security (MACsec) and a network device are provided. The method for generating an SAK includes the following steps. A sending key selection protocol (KSP) instance sends a key selection protocol data unit (KSPDU) to the other KSP instances in the same secure connectivity association (CA). The KSPDU includes a secure connectivity association key identifier (CKI) of the instance and information about a MACsec level that the sending KSP instance belongs to. If the receiving KSP instance and the sending KSP instance belong to the CA with the same MACsec level, an SAK is generated based on the KSPDU. The MACsec of multiple levels in a communication network and the secure MACsec network communication with multiple levels are realized, thus ensuring the confidentiality of the network communication.

Abstract: A method for avoiding label collision in PBT controlled by GMPLS is provided. The method is as follows. A label to be assigned is selected for a label switched path (LSP) to be established. It is judged whether the label selected from labels to be assigned is repeated by previously assigned labels. The selected label is used as the label of the LSP if the selected label is not repeated by any of the previously assigned labels. The embodiment of the present invention also provides a device for avoiding label collision. Thus, the problem of label collision in PBT controlled by GMPLS is effectively solved.

The method includes: selecting, by a current network, another network to execute a paging procedure, when receiving user data and determining a corresponding communication interface of the terminal device in the current network to be in a Dormant Mode, where the another network uses wireless standards different from the current network; sending, by the another network, a paging message to the terminal device to enable the terminal device to reconnect to the current network. A terminal device and network system is also provided.

Abstract: A redirector, a relay, a system for configuring route information, and a method for updating route information are disclosed herein. The redirector includes: a route storing module and a route indicating module. The redirector further includes: a monitoring module which is coupled to communicate with the route storing module and configured to monitor change of the route configuration information; and a notifying module which is coupled to communicate with the monitoring module and configured to send a notification to the intermediate node managed by the redirector, where the notification indicates that the route information corresponding to the changed route configuration information is invalid. Through the foregoing solution, after the route configuration information changes, a notification may be sent in time to indicate that the previously subscribed route indication information is invalid, thus better ensuring correct forwarding of the service request message and improving the QoS.

Abstract: A loop withdrawal method in multi-protocol label switching is disclosed. When detecting a rewinding event of colored thread, a node judges whether an upstream interface of the colored thread is in a stalled status, and if yes, prohibits distribution of a colored thread rewinding message via the upstream interface of the colored thread; otherwise, the node continues to distribute the colored thread rewinding message and transmit label mapping via the upstream interface. When detecting a withdrawal event of the colored thread, the node removes colored thread information of the upstream interface of the colored thread, judges whether the node has received another colored thread for a same service, and if yes, extends a new colored thread via a downstream interface of the colored thread; otherwise, the node continues to distribute a colored thread withdrawal message via the downstream interface of the colored thread.
