摘要:
The present invention provides a system (100) for managing at least one network service (101). The system (100) comprises at least one network node (102) including at least one connection tracking module (103), which is configured to perform connection tracking on at least one packet belonging to a network service session. Further, the system also comprises at least one external data storage or memory (104) configured to store connection tracking data obtained by the at least one connection tracking module (103 9, and to share the stored connection tracking data (105) across all network nodes (102).
摘要:
The present invention provides a system for detecting and preventing the intrusion of malicious data flows in a software defined network (SDN). The system comprises at least one data storage or memory, configured to store flow states of data flows, and to share and update the flow states across the system, at least one shared-state forwarding element (FE) configured to block, forward, or replicate a received data flow based on a flow state of the data flow and/or a comparison of the data flow with predetermined patterns, and at least one inspection element (IE), configured to receive a replicated data flow, and to classify, whether the data flow is malicious or allowed. The IE is configured to alter the flow state of the data flow according to a classification result. The present invention provides a corresponding method for detecting and preventing intrusion of malicious data flows in a SDN.

摘要:
The present invention relates to a method for discovering network-level proximity between nodes (141, 143, 205, 206) of a software-defined data centre, SDDC, (100, 200), wherein the SDDC (100, 200) comprises hosts (111-118, 121-128, 211-218, 221-228), each host being connected to one of the nodes (141, 143, 205, 206), the method comprising discovering the network-level proximity between the nodes based on a software-defined networking, SDN, control plane protocol.

The present invention provides a system 100 for managing a network. The system 100 comprises at least one service network node 102 including at least one connection tracking module 103, which is configured to perform connection tracking on at least one packet belonging to a network service session. Further, the system 100 also comprises at least one external data storage or memory 104 configured to store connection tracking data obtained by the at least one connection tracking module 103. Finally, the system 100 comprises an application network node 106 including a common application layer configured to drive at least one application 108 based on the stored connection tracking data 105.
摘要:
The present invention provides a method (100), system (200, 300) and computing device configured for invoking software application methods of remote Java objects. Therein, a client (201) sends (101) at least one remote Java application object request to at least one of a plurality of Java application server instances (202). An SDN application (204) located in the network path between the client (201) and the plurality of Java application server instances (202) receives (102) the at least one remote Java application object request, and forwards (103) the at least one remote Java application object request to the plurality of Java application server instances (202). Then, the SDN application (204) generates at least one remote Java application object pool (302) based on object references received from the plurality of Java application server instances (202) in response to the at least one forwarded remote Java application object request. When the SDN application (204) receives at least one remote Java application method invocation request sent by the client (201) associated with the at least one remote Java application object request, it delegates the at least one remote Java application method invocation request to one or more of the plurality of Java application server instances (202).
