Abstract: In various embodiments, a templated Domain Name System (DNS) nameserver respond to DNS to DNS requests, and a templated HyperText Transfer Protocol (HTTP) server respond to HTTP and Hypertext Transfer Protocol Secure (HTTPS) requests. The templated DNS nameserver responds to a DNS request with a predefined response specifying an Internet Protocol (IP) address associated with the templated HTTP server, based on a type of the DNS request. The templated HTTP server responds to an HTTP or HTTPS request with a redirection response specifying a default redirection Universal Resource Locator (URL), or a different URL if the default has been overridden. Domain management is simplified relative to conventional approaches using the templated DNS nameserver and the templated HTTP server. A new domain can simply be registered at a domain name registrar, and the templated DNS nameserver configured as an authoritative DNS nameserver at the domain name registrar.

Abstract: Some implementations enable an inmate communication session without requiring a call be accepted. An inmate initiates a request that is sent to a non-inmate. The request may request that the non-inmate participate in a future communication session. The non-inmate at some point (potentially long after receiving the request), responds to the request by providing input on their device. A scheduling device, in accordance with receiving a response from the second device in response to the request, schedules the communication session at a future time and notifies the inmate and non-inmate of scheduling of the communication session. At the future time, the scheduling device triggers creation of a virtual conference room. In response to a first message from an inmate device, the inmate device is joined to the virtual conference and, in response to a second message from a non-inmate device, the non-inmate device is joined to the virtual conference.

Abstract: This disclosure describes techniques for enabling distributed path computation and centralized path enforcement in a computer network used to implement a software application. In some cases, the disclosed techniques include using a central controller that initializes and coordinates monitoring agents deployed to network regions. The monitoring agents may collect monitoring data associated with application segments in their respective regions and share this data with each other. Using the aggregated data, the agents can compute optimal paths between application segment pairs spanning multiple regions. The optimal inter-region paths may be sent to the controller, which can program the paths into the routing application programming interfaces (APIs) of the various network environments like public cloud and on-premises networks.

Abstract: A system for the isolation of routes in a network is provided. During operation, the system can receive subscription information indicating that a first virtual private cloud (VPC) of the network subscribes to a first route tag. Here, the subscription to a route tag can indicate that a subscriber is to receive routes associated with the route tag. The system can also receive, from a routing protocol instance of the network, a first route advertisement indicating a first route in the network. The first route advertisement can include the first route tag. The system can then determine, based on the first route tag in the route advertisement, that the first VPC subscribes to the first route tag. Accordingly, the system can provide the first route to the first VPC.

Abstract: A method for determining a chain position of a network subscriber in an Ethernet network, in which the network subscribers are connected in a daisy chain. In a first step one of the two ports of the Ethernet gateway is deactivated. In a second step a status message from one of the network subscribers concerning non-connected ports of the network subscriber in question is acquired. In a third step at least one identification number is extracted from the status message from the network subscriber in question and a first chain position is assigned to the identification number. In a fourth step the other port of the network subscriber in question is deactivated. The first through fourth steps are repeated until all of the network subscribers with their identification number have been acquired. Subsequent chain positions are assigned in the repetitions of the third step.
