Abstract: A cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node, that converts received data to analog data suitable to be provided on a coaxial cable for the plurality of customer devices. The plurality of vCores instantiated on at least one of servers is configured within a container to provide services to the plurality of customer devices through the transmission network, where each of the vCores includes a service endpoint that is accessible from within the container while each of the vCores does not include a service endpoint that is directly accessible from a network address exterior to the container. A gateway instantiated one of the servers within the container provides access to each of the vCores using said service endpoint over a non-encrypted channel, and provides access to the gateway from a network address exterior to the container over an encrypted channel.

Abstract: Methods, systems, and computer readable media can be operable to facilitate a testing of an unknown USB supply that is connected to a CPE (customer premise equipment) device to determine a current draw capacity of the USB supply. The CPE device may test the USB supply to determine whether the USB supply is capable of supplying a predetermined current. If the determination is made that the USB supply is not able to supply the predetermined current, an end-user may be instructed to plug an alternative PSU (power supply unit) into the CPE device, wherein the alternative PSU is capable of supplying the predetermined current to the CPE device. The CPE device may output an indication that an alternative PSU should be used via a graphics output to a display device through an HDMI (high-definition multimedia interface) connection or via an LED indication using one or more LEDs at the CPE device.

Abstract: A method for signing data such as software images is provided that uses modules executable by a generic client to sign hashes of the software images rather than the images themselves. The method avoids both the requirement for new or updated client software and the uploading of full software images to the signing system. This approach uses a generic client that requests and downloads processing modules from the signing system to perform the pre-processing operations in signing software images, as well as optionally for post-processing operations.

Abstract: A method to optimize the usage of these crypto resources for effectively sharing the resource with identical configuration crypto material and thereby reducing the operation overhead associated with cryptographic operations is disclosed.

Abstract: During operation, a radio node may provide, at a transmit time during a first time interval, a first instance of a keep-alive message to a computer. Then, the radio node may receive, at a receive time prior to a first instance of a transmit expire time, an instance of a keep-alive response from the computer, where the instance of the keep-alive response authorizes the radio node to transmit in a granted portion of the spectrum until a second instance of the transmit expire time has elapsed. Moreover, the radio node may determine, based at least in part on the receive time and the first instance of the transmit expire time, an updated transmit time. Next, the radio node may provide, at the updated transmit time, which is prior to the second instance of the transmit expire time, a second instance of the keep-alive message addressed to the computer.

Abstract: Techniques for efficient content delivery in an MABR system. Precisely, the disclosure recites a method comprising receiving, at an MABR client device, a manifest request from an ABR player, wherein the manifest request is initially redirected to the MABR client device by a rendezvous service upon updating the manifest request with a channel ID and an upstream CDN base information. The method further recites translating, by the MABR client device, the manifest request with a representation ID and obtaining a stream ID from the translated manifest request. The method further discloses performing look up in a cache for media content, requested in the translated manifest request, using the obtained stream ID.

Abstract: In some embodiments, a method receives a first signal that is sent in a first direction in a network. Communications in the network are full duplex communications in a same frequency band. The first signal is amplified in the first direction. The method trains a first echo canceller to cancel a first echo signal from the first signal where the first echo signal is received in a second direction. After training the first echo canceller, the trained first echo canceller is enabled. The method receives a second signal in the second direction that is sent in the second direction in the network. The second signal is amplified in the second direction. The method trains a second echo canceller to cancel a second echo signal received in the first direction from the second signal where the first echo canceller cancels the first echo signal that is received in the second direction.

Abstract: Methods, systems, and computer readable media can be operable to facilitate dynamic port forwarding. A CPE device may be configured to dynamically modify one or more port forwarding rules based upon a detection of changes at the CPE device, one or more client devices, and/or a local network that is supported by the CPE device. In response to a steering of a client device to a network extender, the CPE device may amend port forwarding rules to forward traffic from the CPE device to the network extender for delivery to the client device. In response to a detection of a low quality parameter value for a first client device, the CPE device may amend port forwarding rules to forward traffic associated with the first client device to a second client device, wherein the second client device is identified as a device supporting interchangeable services with the first client device.
