      How to ensure automation drives effective NFV/SDN orchestration

      By: Vikas Arora | Category: Big data analytics, SDN/NFV, Test orchestration | Posted date: 2017-03-21 | Views: 2701

      Software-defined networks (SDNs) leveraging virtual network functions (VNFs) promise to reshape the networks of communications service providers (CSPs) in order to enable new, faster and more customizable services, while simultaneously allowing CSPs to optimize network resources and reduce operating expenses. No doubt, this is a tall order to fill, and one that requires a different way of operating.

      Evolving from Backhaul to Fronthaul with C-RAN

      By: Vikas Arora | Category: Carrier Ethernet Networks, Backhaul (OBSAI, CPRI, GigE), Private/Utility

      According to a 2014 Infonetics survey, 45% of mobile operators plan to deploy remote radio heads (RRHs) as an alternative or complement to small cells, to create denser coverage and capacity on their networks. But connecting  a group of RRHs to a stack of baseband units, usually deployed in a CO, has specific challenges. This webinar examines the requirements for RRH and for extending it to full Cloud-RAN (or C-RAN) topologies, and also discusses considerations for integrating fronthaul connectivity into the backhaul network.

      Mastering Small Cell Deployments with Limited Budget, Resources and Efforts

      By: Thierno Diallo, Vikas Arora | Category: Service Assurance: Network and Fiber Performance/Integrity Monitoring

      With the rise of mobile broadband, mobile network operators (MNOs) are facing an incredible challenge in terms of delivering mobile QoE while maintaining low operation costs. To meet the rising demands of mobile broadband subscribers and mobile service usage, small cells are a promising solution that enable operators to deploy small and focused access points in order to alleviate congestion and increase coverage in smaller zones. However, small cells also pose significant challenges to operators, from deployment to troubleshooting.
