Testing Challenges for Next Generation Metro/Edge Routing DevicesService providers have invested very heavily to increase capacity in their core network in response to industry predictions that bandwidth demand would soon exceed supply in the network core. In reality, traffic growth estimates were hugely inflated, resulting in excess bandwidth and equipment capacity in the network core.
The ‘if you build it - they will come' philosophy, and assumption that a high-capacity network is all you need to attract business has proved wrong, resulting in fierce competition amongst service providers, and significant industry consolidation. Service providers are now searching for ways to both:
- reduce operating expenses
- capitalize on their considerable investment by offering new revenue-generating, network-differentiating services and applications over their core infrastructure
This has fuelled investment in, and development of, a new breed of metro/edge devices that promises to satisfy both service provider objectives.
