While the technological benefits of using software defined networking (SDN) to help operators dynamically provision network applications and services have been well publicised, the economic benefits that the technology could bring are now being articulated.
Global mobile traffic is expected to grow nearly 11-fold over the next four years, according to research conducted by networking kit vendor Cisco.
Mobile backhaul and optical networking specialist Tellabs has announced that it is to be bought by private equity firm Marlin Equity Partners for $891m, or $2.45/share. Tellabs said that it had accepted the offer from Marlin, which in December last year bought NSN’s optical business, after contacting more than 30 potential buyers.
Software defined networking (SDN) is much talked about and so far has been used to optimise datacentre resources in the cloud. It has been much discussed in the telco sphere and operators have tested SDN applications for operational network elements but the application of SDN to transport and backhaul optimisation has only started so recently that there is little quantification to support SDN business cases for service providers. That may soon change however, as research released Thursday found that SDN can almost half the perceived “backhaul shortfall” and save operators just under $5bn in capital expenses by 2017.
