The concepts and technologies disclosed herein are directed to a network-assisted Raft consensus protocol, referred to herein as 'NetRaft.' According to one aspect of the concepts and technologies disclosed herein, a system can include a plurality of servers operating in a server cluster, and a plurality of P4 switches corresponding to the plurality of servers. Each server of the plurality of servers can include a back-end that executes a complete Raft algorithm to perform leader election, log replication, and log commitment of a Raft consensus algorithm. Each P4 switch of the plurality of P4 switches can include a front-end that executes a partial Raft algorithm to perform the log replication and the log commitment of the Raft consensus algorithm. The back-end can maintain a complete state for responding to requests that cannot be fulfilled by the front-end. The requests can include read requests and/or write requests.

Aspects of the subject disclosure may include, for example, receiving network information for a group of video sessions. Embodiments include calculating an overall video traffic metric for the group of video sessions for each cell based on the network information and include determining a first overall video traffic metric of a first cell is above a first predetermined threshold and a second overall video traffic metric of a second cell is below the first predetermined threshold. Also, embodiments include generating a graphical map that indicates the overall video traffic metric for each cell in the cellular network and sending the graphical map to a mobile device in the first cell showing first overall video traffic metric and the second overall video traffic metric relative to the first predetermined threshold. Other embodiments are disclosed.
