Packet mode kutaurirana kunogona kuitwa kana pasina ma intermediate forwarding nodes (packet switches kana ma routers). Packet dzinowanzotumirwa nepakati network nodes asynchronously uchishandisa yekutanga-mukati, yekutanga-kunze buffering, asi inogona kutumirwa zvinoenderana nechimwe chirongwa chekuronga chekumirira zvakanaka, kugadzira traffic, kana kusiyaniswa kana kuvimbiswa kwemhando yebasa, senge kuremerwa kumirira zvakanaka kana leaky bucket. Muchiitiko chechinhu chemuviri chakagoverwa (senge redhiyo kana 10BASE5), mapakeji anogona kuendeswa zvinoenderana nechirongwa chekuwana zvakawanda.
