2 results about "Down link" patented technology

A communication device in a communication network includes at least one processor. The at least one processor is configured to at least one processor configured to search a spectrum of the communication network using a Long Term Evolution Primary Synchronization / Secondary Synchronization Signals (LTE PSS / SSS), estimate the LTE interference using cell specific reference signals for Down Link (DL) when the LTE PSS / SSS signal is detected, and utilize LTE cell specific reference signals (CRS) and feed the equalized signal to a Data Over Cable Service Interface Specification (DOCSIS) Physical Layer (PHY) engine.

Disclosed are methods, controllers, and computer-readable media that explicitly label data packets and interfaces as trusted or untrusted. The data packet labeling can occur at a centralized security hub or at the enforcement site itself, i.e., at the interface to the trusted or untrusted region. The packet can be labeled with metadata associated with the packet, and that label can be carried through the transport of the packet to avoid overbroad or unnecessary security procedures. Further, a network administrator can designate certain links as trusted or untrusted so that packets designated as trusted can be sent down trusted links, and untrusted traffic can be sent down untrusted links. Network resources are saved while traffic is better separated and allocated down links with trustworthiness that is congruent with that of the packet.
