Multe companii și organizații particulare și-au construit cu timpul propriile rețele de arie largă.

Liniile telefonice închiriate (<i>leased lines</i>) sunt scumpe. Mai convenabile sunt legăturile comutate (nededicate) cum ar fi cele bazate pe circuite comutate sau și pachete comutate. Aceste rețele au nevoie de protocoale (reguli de funcționare) care asigură transportul și adresarea mesajelor, așa cum ar fi familia de protocoale <a href="/wiki/TCP/IP" title="TCP/IP">TCP/IP</a>. </p><p>Pentru rezolvarea linkurilor folosite în WAN-uri companiile ISP folosesc deseori protocoale ca de ex. <a href="/w/index.php?title=Pachet_pe_SONET/SDH&action=edit&redlink=1" class="new" title="Pachet pe SONET/SDH — pagină inexistentă">POS</a> (plasare de pachete IP sau Ethernet), <a href="/w/index.php?title=MPLS&action=edit&redlink=1" class="new" title="MPLS — pagină inexistentă">MPLS</a>, <a href="/wiki/Mod_de_transfer_asincron" title="Mod de transfer asincron">ATM</a> și „<a href="/wiki/Releu_de_cadre" title="Releu de cadre">releu de cadre</a>”.
