Abstract: An example system and method for facilitating virtual cable modem termination system VCMTS redundancy in cable modem network environments is provided and includes spawning a first instance of a virtual network function (VNF) on a first server in a cable modem network, spawning a second instance of the VNF on a different second server, configuring the second instance to be communicatively coupled to the first instance in a same subnet of the network, and synchronizing (e.g., copying, coordinating, matching, etc.) state between the first instance and the second instance. In specific embodiments, the VNF comprises a VCMTS.

Abstract: In some embodiments, a user equipment device (UE) implements a method for discovering the presence of neighboring UEs using an on-demand discovery signal transmission technique. This discovery process may be performed to enable the UEs to perform peer-to-peer communications with each other, wherein peer-to-peer communications is defined as direct communication between the UEs without involving a base station. The UE may be configured to transmit a discovery request signal when it has moved greater than a threshold amount since transmission of a prior discovery request signal. The discovery request signal causes one or more neighboring UEs to each transmit a discovery signal in response, and also causes the UE which generated the discovery request signal to transmit its own discovery signal. The received discovery signal from each of the neighboring UEs is useable to discover, or detect the presence of, these neighboring UEs.

Abstract: The disclosed embodiments include a system, method, and computer program product for improving network performance. For example, in one embodiment, a computer-implemented method for improving network performance includes determining network performance information data indicative of network transmission characteristics of a first set of data packets that are communicated, using a first data link layer protocol, over at least one link of a network. The method further includes the step of improving, using a processor, transmission of a second set of data packets over the network, which utilizes a second data link layer protocol, based on the network performance information data determined from the first set of data packets that are communicated using the first data link layer protocol.
