  • Patent number: 11438254
    Abstract: A method is implemented by a switch in a software defined networking (SDN) network to trace packets in a packet processing pipeline of the switch. The method includes creating a copy of a received packet to function as a trace packet. The method further includes, at each of one or more subsequent flow tables that the trace packet traverses, appending an identifier of that flow table to a recorded route of the trace packet and resubmitting the trace packet to that flow table to be processed without packet tracing. The method further includes sending, at an egress table, the trace packet to a controller along with the recorded route of the trace packet.

  • Patent number: 11418396
    Abstract: Some embodiments provide a method, executable by a network device, that receives a packet from a network at a first port of the network device. The method further sends the packet to a second port of the network device. The second port includes an interface and a loopback function implemented at an egress of the interface. The loopback function is configured to transmit the packet back to the network device through the interface. The interface is configured to truncate the packet upon receiving the packet from the loopback function. Upon receiving the truncated packet from the interface of the second port, the method also forwards the truncated packet to a device through a third port of the network device that is coupled to the device.

    Abstract: A monitoring solution allows for testing of forwarding states on network devices. In a particular example, an agent on a router A directs a probe packet to a first neighbor device. The first neighbor device reflects the probe back to the router A. The reflected probe packet undergoes a forwarding state lookup similar to other network traffic and is routed to a second neighbor network device. The second neighbor network device reflects the probe back to router A, which can then intercept the packet and redirect it to an agent on router A for verification whether the lookup was performed correctly.

  • Patent number: 11032249
    Abstract: A server in a captive portal accepts a connection from a user device to the IP address of the server and receives a HTTP or HTTPS request over the connection. The connection may be a result of the user device being previously determined to be not logged in, and consequently provided the IP address of the server as a DNS resolved IP address, the user device thereafter caching the IP address of the server. The server responds with requested content if the target host of the request is a local host. If the target host is a remote destination, the server queries a login database to determine whether the user device is logged in. The server acts as a transparent proxy between the user device and the remote destination if the user device is logged in, else the server sends alternate content to the user device over the connection.

    Abstract: Techniques for launching compute instances on cloud provider network substrate extensions deployed within communications service provider networks are described. A service of a cloud provider network receives a request to launch a compute instance from a customer, the request including a latency requirement. A provider substrate extension is selected to host the compute instance from a plurality of provider substrate extensions of the cloud provider network based at least in part on the latency requirement. The plurality of plurality of provider substrate extensions are connected to a communications service provider network and controlled at least in part by the service of the cloud provider network via a connection through the communications service provider network. A message is sent to cause the selected provider substrate extension to launch the compute instance for the customer.

  • Patent number: 10972293
    Abstract: An Ethernet transceiver is disclosed. The Ethernet transceiver includes transceiver circuitry having receiver circuitry to receive refresh signals during corresponding refresh cycles from a link partner during a low-power idle mode of operation. Each refresh signal has a refresh period, and where a quiet period is interposed between successive refresh cycles. Signal quality detection circuitry, during the low-power idle mode, determines a measure of signal quality associated with the received refresh signals. Subsequent refresh cycles exhibit at least one of an adjusted refresh period or an adjusted quiet period based on the measure of signal quality.

  • Patent number: 10958493
    Abstract: A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.
