I don&#x27;t think it really applies to a packet switched network:
 &gt; adding extra capacity to a network when the moving entities selfishly choose their route can in some cases reduce overall performance.<p>Network frames don&#x27;t &quot;selfishly choose their route&quot; and are entirely at the whims of the Routers they pass through.<p>Because of complex routing and suboptimal peering&#x2F;routing, a &quot;shortcut&quot; could be added that makes it quicker to get from A to X1 but makes it take much longer to get from A to X2
Additional routes (as in &quot;directing packets the right way&quot;, not physical routes) would fix this and get the best of both worlds.
