    Abstract: The disclosure provides a controller, a method for adjusting packet flow rule, and a network communication system. The method includes: receiving, by a controller, a health status of a first port and a health status of a second port of each of a plurality of hosts in the network communication system; adjusting a packet flow rule of each of the hosts based on the health status of the first port and the health status of the second port of each of the hosts; and transmitting the adjusted packet flow rule of each of the hosts to each of the corresponding hosts to control each of the hosts to transceive a packet according to the corresponding packet flow rule.

    Abstract: A method for monitoring traffic in a network is provided. The method is used in a communication device, wherein the network is formed by switches and hosts. The method includes: collecting LLDP information, VLAN information, host NIC information and host-tenant mapping information to obtain a physical network topology and a plurality of virtual network topologies; detecting a plurality of physical link loads of the physical network topology; obtaining a target path between two of the hosts or between the switches by analyzing the virtual network topologies; selecting one of the switches on the target path to serve as a mirror switch according to the physical link load corresponding to the target path or a hop count; and receiving mirror traffic transmitted from the mirror switch, and performing packet payload analysis on the mirror traffic.

    Abstract: A network communication method, a system and a controller of PCIe and Ethernet hybrid networks are provided. In one example of the network communication method, a packet is transmitted or received via a network interface (NIC). The packet is transmitted via an Ethernet over PCIe (EoP) port by adopting a PCIe based EoP architecture based on a PCIe bus for an intra-rack transmission, and the packet is transmitted via an Ethernet port for an inter-rack transmission. If the transmitted packet belongs to a broadcast packet, the network interface receiving the packet discards the packet or transmits the packet to the controller without re-broadcasting the packet again.

    Abstract: An OpenFlow switch, a packet exchanging method thereof, an SDN controller and a data flow control method thereof are provided. The OpenFlow switch includes a network unit, a storage unit and a processing unit. The network unit is connecting to a network, wherein the network at least includes Ethernet switches. The storage unit stores a flow table including action rules, and each of the action rules includes a condition and an action. The processing unit receives a packet, the processing unit analyzes the packet and determines whether the packet satisfies the condition of each of the action rules. If the processing unit determines that the packet satisfies the condition of a first action rule, the processing unit executes the action of the first action rule, which includes: substitutes a flow address for a destination MAC address of the packet, and transmits the packet to the network through the network unit.

    Abstract translation: 提供了OpenFlow开关，其分组交换方法，SDN控制器及其数据流控制方法。 OpenFlow交换机包括网络单元，存储单元和处理单元。 网络单元正在连接到网络，其中网络至少包括以太网交换机。 存储单元存储包括动作规则的流程表，并且每个动作规则包括条件和动作。 处理单元接收分组，处理单元分析分组并确定分组是否满足每个动作规则的条件。 如果处理单元确定分组满足第一动作规则的条件，则处理单元执行第一动作规则的动作，其包括：替换分组的目的地MAC地址的流程地址，并将分组发送到 网络通过网络单元。
