Content Delivery in Wireless Wide Area Networks |
摘要 |
In a content delivery network, a metrics manager processes network topology information from channel measurements collected from at least one of a digi-node field and a client field, and distributes data signals to a selected edge-server set for storage and delivery to client devices. A parent server selects the edge-server set by employing an algorithm that constructs a trellis having a number of states at least equal to a number of edge servers in the edge-server set, wherein each state comprises a plurality of nodes, each node corresponding to one of a plurality of candidate edge servers. A trellis-exploration algorithm provides interconnects between each node of a first state to each of a plurality of nodes in a next state, and for each node in a state, selects a path corresponding to a best performance metric that connects to a node in a previous state, wherein each performance metric comprises the network topology information. |

1. An apparatus configured to select an edge-server set from a plurality of candidate edge servers, comprising:
a metrics manager configured to produce network topology information from channel measurements collected from at least one of a digi-node field and a client field, and to distribute data signals to the edge-server set for at least one of storage and delivery to client devices; and a parent server configured to:
construct a trellis having a number of states at least equal to a number of edge servers in the edge-server set, wherein each state comprises a plurality of nodes, each node corresponding to one of the plurality of candidate edge servers; andemploy a trellis-exploration algorithm to select the edge-server set, comprising providing interconnects between each node of a first state to each of a plurality of nodes in a next state, and for each node in a state, selecting a path corresponding to a best performance metric that connects to a node in a previous state, wherein each performance metric comprises the network topology information. |
