No matter how fast you make a data network or how much bandwidth you provide sooner or later it will be full. The DDS Network was last upgraded in the early 2100s and while currently easily sufficient it is estimated by 2120 the network will be overloaded with the amount of data the DDS will be needing to pass around estimated to increase by 190% by then (and that is a conservative estimate).
The DDS, and UNP, have therefore outlined plans for a new data network in the 2120s, which will be preceded by an upgrade to the main trunks of the network in the next decade. Improved message switching and encyption will also be built into the upgrades. The plans come with a hefty price tag, the interim upgrade is estimated at costing 1.4 billion zarks and a new network over 4.5 billion zarks but the DDS say data is vital and will only become more so as new technologies like DAC and OA 3.0 spread across the DDS plus the number of UCVs increase.
