    Abstract: Server devices operating on the Internet or another wide area network (WAN) are able to locate client devices using address information obtained from a shared location. Client devices initially determine their own network address information and submit the determined information for a priori storage at the shared location on the WAN. Each server device, in turn, contacts a message service or the like to establish a persistent data connection that is maintained between the message service and the server device over time. After the client device stores its own address information, the client initiates contact with the server via the message service having the previously-established persistent connection. Upon receipt of the instruction from the message service, the server is able to retrieve the client's previously-stored address information from the WAN storage and use the information to establish a connection with the client.

    Abstract: Systems and methods for establishing secure remote connections to media devices establish a secure shell (SSH) connection between two machines which are located in two different private networks, such as between a remote debugging computer and a receiving device. The receiving device has a persistent outbound connection with a message server. The remote debugging computer connects to a relay manager and obtains a relay instance IP address and port. The relay manager then forwards the relay instance IP address and port to the receiving device via the message server. After receiving the connection request from the message server, the receiving device connects to the relay instance IP and port and waits for the input data. The remote debugging computer performs an SSH handshake and the receiving device directly authenticates the SSH connection.

    Abstract: Novel techniques are described for lock-free sharing of a circular buffer. Embodiments can provide shared, lock-free, constant-bitrate access by multiple consumer systems to a live stream of audiovisual information being recorded to a circular buffer by a producer. For example, when a producer system writes a data stream to the circular buffer, the producer system records shared metadata. When a consumer system desires to begin reading from the shared buffer at a particular time, the shared metadata is used to compute a predicted write pointer location and corresponding dirty region around the write pointer at the desired read time. A read pointer of the consumer system can be set to avoid the dirty region, thereby permitting read access to a stable region of the circular buffer without relying on a buffer lock.

    Abstract: Various arrangements for performing secure domain name system (DNS) routing are presented. A secure signature may be generated using an internet protocol (IP) address of an authorized device. An encoded character string may be generated that comprises the IP address. The domain name server may receive a request for an IP address mapped to the hostname. The hostname may be validated using the secure signature. The IP address of the authorized device may be decoded from the encoded character string at least partially in response to the hostname being validated by the domain name server. The IP address decoded from the encoded character string may be transmitted at least partially based on the hostname being validated and the request for the IP address.
