Systems, apparatuses, and methods for efficient power management of a multi-node computing system are disclosed. A computing system includes multiple nodes that receive tasks to process. The nodes include a processor, local memory, a power controller, and multiple link interfaces for transferring messages with other nodes across links. Using a distributed approach for power management, negotiation for powering down components of the computing system occurs without performing a centralized system-wide power down. Each node is able to power down its links, its processor and other components regardless of whether other components of the computing system are still active or powered up. A link interface initiates power down of a link with delay or without delay based on a prediction of whether a link idle condition leads to the link interface remaining idle for at least a target idle threshold period of time.

The communication network comprises an SDN network and an edge gateway, the SDN network forwards a request of a terminal to the edge gateway, and if the request is an uplink request, the edge gateway carries out decryption, compression and aggregation processing on the uplink request, carries out compliance evaluation and then sends the uplink request to a cloud block chain; and if the request is a downlink request, the edge gateway returns the downlink request to the terminal. According to the method, the end-edge-chain hierarchical efficient communication network with the software-defined edge gateway as the core is constructed, stable and reliable data uplink is achieved, and the method has the advantages of being low in time delay, high in throughput, self-adaptive and capable of being supervised.

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.

A base station selects a subset of at least one geographically separated antennas for each of the plurality of user equipments.

The base station signals the subset of the plurality of geographically separated antennas via higher layer Radio Resource Control or via a down link grant mechanism. The base station optionally does not signal the subset of the plurality of geographically separated antennas to the corresponding mobile user equipment.
