摘要： Aspects of the present disclosure relate to providing secure access to resources of a private network. For example, a client device may transmit a request identifying the protected resource to an authentication server. The authentication server queries a network address lookup table to identify a network address of the protected resource based on the identifying information of the request. If the network address denotes a network location that is not generally accessible, the authentication server generates a resource record that identifies a bastion host, a port, and a connection method for accessing the protected resource. The resource record and the network address may then be transmitted to the client device. In response, the client device may use the information in the resource record to establish a tunnel connection with the bastion host, and the client device uses the tunnel connection to access the protected resource via the bastion host.

摘要： This disclosure relates to relating time-to-live information with location data for wireless network access points. A freshness component determines a value associated with a freshness of location data for an access point. An encoding component encodes the value into a time-to-live information element included publicly broadcast access point information, and a transmitter transmits the publicly broadcast access point information. The publicly broadcast access point information includes at least one of a beacon frame or probe response. Additionally, by providing a value satisfying a non-inclusion threshold for the time-to-live information, emitters or network administrations may use time-to-live information to indicate that they do not wish to have location data for an access point stored.

摘要： Methods and systems wherein a first network device in a first network maintains attribute information for one or more routes to one or more network devices external to the first network. The first network device is configured to identify that a first route to the second network device external to the first network has a particular network traffic management capability, and to update the attribute information to indicate that the first route to the second network device has the network traffic management capability. The first network device is configured to select the first route for a new network packet flow from the first network to the second network device, based on the recorded information, and route the new network packet flow to an external network in the first route. In some implementations, the first network is a software-defined network.

摘要： A network device may comprise storage media configured to store traffic, instructions for a lookup engine, a map manager, a traffic forwarder, and a map. The map may comprise rules associating IPv4 and IPv6 addresses. The traffic forwarder may be configured to forward outbound traffic to the second device. The lookup engine may comprise instructions to cause the processor to check the map to determine whether the map comprises a rule associating the second address of the second device and the first address of the first device. If so, the instructions may cause the processor to forward the inbound traffic from the second device to the first device. If the map does not comprise this rule, the instructions may cause the processor to send a query to a second network device asking whether the second network device comprises a rule associating the first and second address.

摘要： Exemplary embodiments provide techniques for measuring network latency attributable to the transit of packets through the network. This may be accomplished by developing a common sense of time with the server that allows packet inter-arrival times to be accurately measured. In establishing the common time between the client and the server, it may be necessary to overcome network topology manipulations and/or packet pacing manipulations performed by an intermediate device. Accordingly, an end-to-end multiplexing protocol may be employed which allows a protected connection to be established from the client directly to the server, bypassing the manipulations. Using the multiplexing protocol, a timing flow may be established for carrying timing traffic. After trading timing traffic with the server for a period of time, the client may establish a common or shared sense of time with the server which may be used to measure the latency in the network.
