Network aggregation helps metro operators economically manage the bandwidth explosion

The increasing popularity of IP video, cloud computing and OTT content is exerting tremendous strain on metro networks. This pressure is compounded by the growing number of smartphone and 4G data service users, who are causing more mobile broadband traffic to be backhauled across metro networks.

To stay competitive and boost margins, metro operators are looking for ways to upgrade network capacity while reducing costs. One option is to add new overlay networks with more advanced capabilities. But while this may help temporarily with capacity, it leaves you with a network that is expensive to manage and difficult to scale.

 Moving to an all-IP network is another alternative. What I hear from operators is that IP router-based networks have not lived up to their expectations. The extra equipment requirements, as well as the incremental bandwidth required to transport some service types on an IP network, are making it unfeasible.

A third alternative is metro aggregation using a packet optical transport platform (POTP). By consolidating separate fixed and mobile networks into a single packet-based network, you can offer customers virtually unlimited bandwidth. You can also rapidly turn up a wide variety of service types, including:

  • wavelength services
  • private line services
  • Ethernet services
  • public and private MPLS/VPN services
  • cloud services and data center interconnect
  • mobile backhaul.

And network consolidation with a POTP helps you reduce CapEx and OpEx cost by providing a simpler design that requires less equipment, space, power and resources to manage.
