摘要： A network switch includes a plurality of ports for communicating over a network. Processing circuitry processes inbound frames received from the network via the ports and sends outbound frames to the network. Remote management circuitry (RMU) is responsive to commands received from a host device external to the network switch. The RMU receives via one of the ports a remote access request frame from the host device, wherein at least part of the remote access request frame is encrypted, and decrypts the remote access request frame. In response to successful decryption of the part of the remote access request frame, the RMU accesses one or more configuration registers of the network switch in accordance with the remote access request frame, composes a remote access response frame, at least a portion of the remote access response frame being encrypted, and sends the remote access response frame to the host device.

摘要： Techniques and architecture are described that utilize switchport protected flags to provide switchport protected functionality across network devices, e.g., switches, routers, etc., in fabric networks. For example, a first port of a first network device of a fabric network receives a packet from a first host destined for a second host. The second host is onboarded to the fabric network via a second port of a second network device. It is determined (i) if a first protected flag associated with the first port of the first network device is set as true and (ii) if a second protected flag associated with the second host is set as true. Based at least in part on (i) the first protected flag associated with the first port being set as true and (ii) the second protected flag being set as true, the first network device drops the packet.

摘要： A data transmission method for to a data center including a first site and a second site is disclosed. According to the data transmission method, after obtaining a first data packet sent by a virtual machine at the first site, a switch at the first site identifies a service type of the first data packet, and determines routing information of the first data packet based on the service type of the first data packet; and after determining the routing information, the switch sends the first data packet based on the routing information, where the routing information is used to indicate a bearer link for transmitting the first data packet, and a link through which the first data packet is transmitted to the second site is the bearer link. In this way, the first data packet may be transmitted through a link that corresponds to the service type of the first data packet.

摘要： In one aspect, a computerized system useful for implementing a virtual private network (VPN) including an edge device that automatically establishes an Internet Protocol Security (IPsec) tunnel alongside an unsecure Multipath Protocol (MP) tunnel with a gateway device in preparation for a transmission of a secure traffic communication. The edge device has a list of local subnets. The edge device sends the list of local subnets to the gateway during an initial MP tunnel establishment handshake message exchange between the edge device and the gateway device. Each subnet includes an indication of whether the subnet is reachable over the VPN. A gateway device that automatically establishes the IPsec tunnel alongside the unsecure MP tunnel with the edge device. An enterprise datacenter server that comprises an orchestrator module that receives a toggle the VPN command and enables the VPN on the orchestrator. The orchestrator informs the edge device the list of subnets is accessible over the VPN causing the edge device to update the gateway device with a new list of subnets of the edge device that accessible over the VPN.

摘要： A first ingress interface on a switch receives a first control packet for establishing a Transmission Control Protocol (TCP) session and selects a first engine running on a first line card in the switch. A second ingress interface receives a second control packet and selects the same first engine. Data associated with the TCP session received by the first or second ingress interface subsequent to establishing the TCP session is to be forwarded to the first engine. The first ingress interface receives a third control packet and sends, to the selected first engine, a notification indicating the TCP session which is to be tracked. The first or second ingress interface receives a fourth packet with a payload associated with the TCP session and forwards, to the selected first engine, a copy of the fourth packet, thereby facilitating a plurality of engine instances to support application identification.

摘要： Some embodiments provide a method for configuring a gateway machine in a datacenter. The method receives a definition of a logical network for implementation in the datacenter. The logical network includes at least one logical switch to which logical network endpoints attach and a logical router for handling data traffic between the logical network endpoints in the datacenter and an external network. The method receives configuration data attaching a third-party service to at least one interface of the logical router via an additional logical switch designated for service attachments. The third-party service is for performing non-forwarding processing on the data traffic between the logical network endpoints and the external network. The method configures the gateway machine in the datacenter to implement the logical router and redirect at least a subset of the data traffic between the logical network endpoints and the external network to the attached third-party service.

摘要： The avionic system of an aircraft includes a set of avionic computers and a switch associated with each avionic computer. For each avionic computer of the set of avionic computers, the avionic system includes a communication link between the switch associated with this avionic computer and each of the switches associated with the other avionic computers. Each switch is configured such that it routes the data frames received on its input ports to its output ports in a manner predefined only on the basis of the input ports on which these data frames are received. The various switches are configured such that, when an avionic computer sends a data frame, this data frame is transmitted to all of the other avionic computers.

摘要： This disclosure describes methods, devices, and systems related to coordinating channel switch times and specifying device operation (for example, transmitting device operation) to ensure data reception by one or more devices (for example, receiving devices). A device may receive a data path setup request frame from a second device. The device may cause to send a data path setup response frame. The device may cause to establish a communication with the second device on a first channel. The device may cause to establish a communication with the second device on a second channel at a first time. The device may cause to wait, by the device, at least for a duration specified by a channel switch time (CST) parameter. The device may cause to send device data to the second device over the first channel or the second channel based at least in part on the CST parameter.
