SELF-ORGANIZED STORAGE NODES FOR DISTRIBUTED DELIVERY NETWORK

摘要

A distributed delivery network for capacity enhancement of a communication link shared by multiple communication devices for network access service. The distributed delivery network may include one or more distributed storage devices, some of which may include at least one rotating disk storage device, a network interface, and one or more environmental sensors. Each distributed storage device may monitor data from the environmental sensor(s) and transition between an active state where messages are stored in or retrieved from the storage device, and a standby state where access is suppressed. The distributed storage devices may self-organize control operations for the distributed delivery network including message storage and retrieval and redundancy of messages, which may be determined by frequency of requests for the messages.

主权项

1. A communications system comprising:
a network gateway device; a plurality of distributed storage devices coupled to the network gateway device, a distributed storage device of the plurality of distributed storage devices comprising:
a housing;a rotating disk storage device within the housing;a network interface to support communication with the network gateway device;a sensor to produce a sensor signal indicating a characteristic of an environment external to the housing; anda control circuit to detect an adverse operating condition for the rotating disk storage device based on the sensor signal, and to transition the distributed storage device from an active state to a standby state upon detection of the adverse operating condition, wherein:in the active state, the distributed storage device enables access of the rotating disk storage device to store messages received via the network interface, to retrieve the stored messages in response to requests received via the network interface, and to provide a given stored message of the stored messages for redundancy of storage within other distributed storage devices of the plurality of distributed storage devices based on a frequency of requests for the given stored message; andin the standby state, the distributed storage device prevents access to the rotating disk storage device.
