A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user's account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

Embodiments of the present disclosure provide methods, systems, apparatuses, and computer program products for an improved communication network. In one embodiment, a method is provided comprising receiving, at a first device, a first signal over a first medium, the signal comprising a first portion and a second portion, and extracting by a processor a third portion of the first signal, the third portion being at least a portion of the first portion of the first signal, the third portion being intended for receipt by a second device associated with a particular user account. The method may further include combining at least a fifth portion of the first signal with the third portion of the first signal to generate a second signal, the fifth portion of the first signal being at least a portion of the second portion of the first signal and providing the second signal to the second device.

Systems, methods, apparatus and computer-readable medium are described for improving efficiency and robustness for processing network packets at a network device, such as a customer premises equipment (CPE). The network device may include a plurality of physical network interfaces for receiving and transmitting network packets, and one or more processing entities. The one or more processing entities may provide a first router for providing routing functionality, wherein the first router is not virtualized, enable a virtual machine to execute a second router for providing routing functionality and forward a network packet using the first router or the second router from the device. The one or more processors may be configured to execute instructions associated with the first router from user space.

A transfer apparatus has an input port and an output port, an input line speed of the input port and an output line speed of the output port being capable of being set to differ from each other. The transfer apparatus comprises, for each output port: a low-latency frame transmission buffer to store a low-latency frame received at the input port; a normal-latency frame transmission buffer to store a normal-latency frame that is a frame received at the input port, the normal-latency frame being permitted to be transferred with higher latency than the low-latency frame; a time calculation unit to calculate output start time of the low-latency frame by using information on a frame length of the low-latency frame, the input line speed, and the output line speed when the low-latency frame is received; and an output contention control unit to control transfer of the low-latency frame and the normal-latency frame by using the output start time.
