Staying current on WAN connectivity technology is the first step to ensuring the WAN is operating at peak efficiency. Take an inventory of existing WAN connectivity as the next step to reaping significant cost savings.
Why Inventory?
Network managers who do not have an accurate inventory of WAN circuits are not alone. It is commonplace to view the invoices received from telcos/ISPs as an inventory. However, changes made to the WAN infrastructure are often not reflected on invoices from the WAN provider. The accuracy of telco/ISP invoices are suspect and network managers should not rely on them.
