Abstract: Disclosed is a gateway which includes a communication circuit, a memory, and a processor operatively connected with the communication circuit and the memory. The processor receives a data packet of a node through a network processing layer, identifies whether there is data flow corresponding to the data packet of the node and authorized from an external server, inspects authentication information of the data packet, when there is a need to inspect the authentication information of the data packet based on authentication information included in the data flow, generates data flow identification information capable of being identified by an application processing layer based on the data packet and forward the data packet to the application processing layer, and processes the forwarded data packet based on the data flow identification information by means of the application processing layer.

Abstract: Methods and systems are provided to facilitate network ingress fairness between applications. At an ingress port of a network, the applications providing data communications are reviewed so that and arbitration process can be used to fairly allocate bandwidth at that ingress port. In a typical process, the bandwidth is allocated based upon the number of flow channels, irrespective of the source and characteristics of those flow channels. At the ingress port, an examination of the application providing the data communication will allow for a more appropriate allocation of input bandwidth.

Abstract: A method by a first controller in a software defined networking (SDN) network for programming a switch in the SDN network to use a controller port as a watch port. The method includes generating an instruction for the switch to create a first group entry for a first group in a packet processing pipeline of the switch, where the first group entry includes a first bucket that specifies a first controller port as a watch port and an action for the switch to forward packets to the first controller via the first controller port, where the first controller port being specified as the watch port in the first bucket indicates that execution of the action specified by the first bucket is to be contingent upon a liveness of the first controller port and sending the instruction to the switch to cause the switch to create the first group entry.

Abstract: Embodiments of the present disclosure provide a packet processing method and a network device, so as to effectively resolve a problem that a quantity of concurrent packet processing policies is limited in a network device due to scarce hardware resources of a packet forwarding chip. A method part in the embodiments of the present disclosure includes: obtaining, by a first network device, identification information; processing, by the first network device, a packet when receiving the packet, where a processed packet includes the identification information, and packets corresponding to different preset policy information include different identification information; and sending, by the first network device, the processed packet to a second network device, so that the second network device matches a corresponding policy for the processed packet based on the identification information.

Abstract: Embodiments described herein generally involve identifying workloads in a multi-site networking environment. Embodiments include determining that a given network is stretched across a first network segment at a first site and a second network segment at a second site. Embodiments include creating a stretched administrative domain for the given network and mapping an address of the given network to the stretched administrative domain in a lookup table for an administrative domain associated with the first network segment. Embodiments include receiving a flow record from an observation point in the first network segment, the flow record having a source IP address associated with the second network segment and a destination IP address associated with the first network segment. Embodiments include identifying a source workload and destination workload of the flow record using the lookup table and a workload identification table that maps combinations of IP addresses and administrative domains to workloads.

Abstract: Systems and methods are provided for “on the fly” routing of data transmissions in the presence of errors. Switches can establish flow channels corresponding to flows in the network. In response to encountering a critical error on a network link along a transmission path, a switch can generate an error acknowledgement. The switch can transmit the error acknowledgements to ingress ports upstream from the network link via the plurality of flow channels. By transmitting the error acknowledgement, it indicates that the network link where the critical error was encountered is a failed link to ingress ports upstream from the failed link. Subsequently, each ingress port upstream from the failed link can dynamically update the path of the plurality of flows that are upstream from the failed link such that the plurality of flows that are upstream from the failed link are routed in a manner that avoids the failed link.
