摘要: A Method and a system for securing a SDN controller from denial of service attack are provided. A SDN controller receives, from a networking device, data packets pertaining to a flow in Packet_IN messages, if the flow does not match flow entries in a first flow table of the networking device. A table miss flow entry pertaining to the flow is created in a second flow table of the networking device for sending the Packet_IN. The SDN controller installs a flood prevention flow entry in the second flow table to enable the networking device to drop subsequent data packets pertaining to the flow until the SDN controller installs, in the first flow table, a flow entry matching the flow. The flood prevention flow entry is deleted from the second flow table after the installation of the flow entry matching the flow.

摘要: Systems and methods are provided to add flow validation information to packets of network traffic. Each packet can have flow validation information added corresponding to the source and destination of the packet. A stateful network routing service may intercept packets and obtain or generate flow validation information based on the source and destination of the packet. The stateful network routing service may add the information to the packet and transmit the enriched packet to a network appliance. The stateful network routing service may receive a second enriched packet from the network appliance. The stateful network routing service can compare the enriched packet with the second enriched packet. Based on the comparison of the enriched packets, the stateful network routing service can determine whether the packet should be transmitted to the destination or dropped.

摘要: There is disclosed a router for routing data on a computing chip comprising a plurality of processing elements, the router comprising: a packet processing pipeline; a dropped packet buffer; and one or more circuits configured to: determine that a data packet in the packet processing pipeline is to be dropped; move the data packet that is to be dropped from the packet processing pipeline to the dropped packet buffer; and re-insert the dropped data packet from the dropped packet buffer into the packet processing pipeline for re-processing.

摘要: A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

摘要: The present invention relates to a method of transmitting a data unit by a user equipment (UE) belonging to a UE group in a wireless communication system. Especially, the method includes the steps of receiving the data unit from an upper layer; associating first time information with the data unit; transmitting a request message for transmitting the data unit; receiving an uplink grant with second time information related to the UE group in response to the request message; transmitting the data unit with the first time information on the uplink grant based on the first time information not being matched with the second time information, wherein the data unit is discarded based on the first time information being matched with the second time information.

摘要: An apparatus, comprising at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry is disclosed. The at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least, upon receipt of a deterministic data flow of data packets having a logical relation to each other, to identify the deterministic data flow based on a first control information provided at the apparatus. The apparatus is further at least caused to switch a forwarding status of the apparatus between a first status and a second status based on a second control information, and, in the first status, to decide whether to buffer or discard a data packet of the deterministic data flow of data packets based on a third control information.
