In the Internet+ era, video, DC,
and cloud-based enterprise services drive network evolution towards a DC-centric ultra-broadband network architecture.
Enterprise scales have become increasingly polarized, whereas large Internet service providers (ISPs) are encouraged to construct their own backbone networks.
ISPs are facing the following challenges:
Inter-DC data is growing substantially.
The network needs to carry multiple services to meet various ISPs' requirements.
Dynamic adjustment of private line bandwidth can effectively reduce network leasing costs.
Network availability and reliability are major concerns of ISPs. Reliability has become one of the most important factors for evaluating network performance.
Cloud-based services place increasingly higher requirements on network latency.
Fast service provisioning is required in the ever-increasingly competitive ISP industry.
A solution that provides simple maintenance, quick locating, and easy scalability is also required.
Facing these challenges, the ISP multi-service transport solution provides the following functions:
