摘要： For managing a traffic overload in a software defined network (70) having an SDN controller (10), when an indication of a traffic overload is received (200), there are steps of identifying (208) traffic flows which contribute to this, identifying (210) nodes (20, 21, 22) of the network controllable by the SDN controller and located along a path of the identified traffic flows before the location of the traffic overload. The SDN controller is used to control (220) the identified nodes to control the identified traffic flows to reduce the traffic overload. By using the SDN controller to control the reduction compared to diverting suspicious traffic flows to a separate external security server, the extra network resources used for carrying the diverted traffic flows are not needed, the separate security server is not needed, and the risk of such diverted traffic flows themselves causing overloads is reduced. It can be applicable to a range of causes of overload, including denial of service attacks.
摘要翻译：为了管理具有SDN控制器（10）的软件定义网络（70）中的业务过载，当接收到业务过载的指示（200）时，存在识别（208）有助于此的交通流量的步骤，识别（210）节点（20,21,22），其可由SDN控制器控制并且沿着所识别的业务流的路径在流量过载的位置之前定位。 SDN控制器用于控制（220）所识别的节点，以控制识别的流量，以减少流量过载。通过使用SDN控制器来控制与将可疑流量转向单独的外部安全服务器相比的减少，不需要用于承载转移流量的额外网络资源，不需要单独的安全服务器，并且存在这样的风险转向流量本身导致过载减少。它可以适用于一系列过载的原因，包括拒绝服务攻击。

摘要： Tone Reservation scheme for optical OFDM where the reserved tones are located outside the allocated transmit frequency band (out- of-band reserved tones). A plurality of peaks in the time-domain digital signal after IFFT are cancelled by adding amplitude and phase adjusted selected pre-calculated peak cancellation signals. Said cancellation signals are filtered out before transmission. Multiple peaks can be cancelled per symbol by using disjoint subsets of reserved tones.

摘要： This invention relates to a unit (200) and a system (290) for protection switching of line cards (270,280) in a telecommunication system. Known solutions implement a so called protection bus which has several disadvantages. It does for example not allow for different simultaneous protection switching configurations. The current invention overcomes these disadvantages and comprises a protection unit (200) connectable between the communication lines (250) and the line interface unit (270). The protection unit (200) is interconnected with other protections units (210,220) with detachable electrical connection elements (251,252) to form a protection switching system (290). One protection unit (210) in the protection switching system (290) is connectable to a standby line card (260). The protection switching system (290) is adapted so that when protection switching is needed the line signal is re-directed between the communication line (240) for a failed line card (280) and the standby line card (260) via the electrical connection elements (251,252).
