      Network-wide Latency Maps for Mesh, Hybrid and Cloud Networks

      By: Thierno Diallo | Category: Network and service monitoring, SDN/NFV | Posted date: 2017-07-13 | Views: 2288

      A key driver behind mesh, hybrid and cloud based networks is the ability to optimize service paths and application server locations to ensure performance metrics continue to be met. Knowing in advance how moving an application server or changing the service path will impact latency is critical to ensuring that the customer’s overall quality of experience (QoE) is maintained.

      Performance assurance in LTE-A and 5G virtual and hybrid networks

      By: Thierno Diallo | Category: Big data analytics, Internet of Things (IoT), Network and service monitoring, SDN/NFV | Posted date: 2017-06-26 | Views: 1744

      Your mobile backhaul network is working just fine. You very seldom see issues with regards to service delivery and quality, and certainly nothing that can’t be identified and fixed quickly. So, besides a bit of scaling to accommodate more traffic, your network is LTE-A- and 5G-ready, right? Not so fast!

      How do you upgrade your network for one-way delay metrics without breaking the bank?

      By: Thierno Diallo | Category: Big data analytics, Ethernet IP, Network and service monitoring | Posted date: 2017-06-16 | Views: 2139

      Today’s services, and consequently the networks that carry them, are highly asymmetrical. Most bandwidth-hungry applications, such as IP Video, require much more bandwidth downstream than upstream. At the same time, self-optimization technologies, such as software defined networking (SDN), no longer require the upstream and downstream traffic to follow the same path through the network.

      Is your network 5G-ready? Probably not!

      By: Thierno Diallo | Category: Big data analytics, Internet of Things (IoT), Network and service monitoring, SDN/NFV | Posted date: 2017-06-02 | Views: 2001

      Everyone has read the news. Mobile data is on the rise, driven by an ever-growing number of new apps and a video content streaming explosion. Furthermore, LTE-A and 5G promise to fuel this growth by bringing more bandwidth to the mobile device. According to the most recent Cisco Visual Networking Index (VNI) Global Mobile Data Traffic Forecast Update, mobile data grew by 63% in 2016 to 7.2 exabytes per month by the end of 2016.

      Service Quality: See It from the Subscriber’s Point of View

      By: Thierno Diallo | Category: Big data analytics | Posted date: 2015-10-23 | Views: 6809

      When adding differentiated service offerings to monetize new access and applications, providers are faced with new challenges. When it comes to business services, providers need to keep customers happy by delivering additional flexibility while assuring the quality and performance of the new services. To compound the situation, limited options are available in terms of solutions that are capable of continuously measuring and assuring the level of application performance experienced by end users.

      Solving the Challenge of Assuring Business Services

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

      Revenues from business services are growing at a fast pace with customers demanding a high quality of service and experience in return for premium services. Operators have long struggled to assure the delivery of services across an increasingly complex network. To succeed in this challenging market, the following are critical:

      • Assuring E2E IP performance
      • Delivering stringent SLAs
      • Supporting the delivery of demanding VoIP and Video applications

      TCP Performance Testing and Our Approach (with Live Demo)

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

      With more and more subscribers and the growing data load on packet networks, service providers have to cope with heightened performance pressure. Loss and latencies are daily occurrences but the impact of these network events has very different effects on User Datagram Protocol (UDP) traffic as compared to Transmission Control Protocol (TCP) traffic. Contrarily to UDP, TCP performance is greatly impacted by loss and latency as well as incorrect configurations. This is why service providers have to struggle to effectively and correctly troubleshoot TCP performance issues or qualify TCP performance at activation.


      The Evolution of Service Assurance (RCR Wireless)

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

      Service assurance has been an ongoing struggle for wireless carriers as they look to balance their spectrum and network assets with growing consumer demand. Advances in software have become the latest tools use by mobile operators, including the move towards virtualization in order to become more agile in handling service assurance demands. This webinar will look to provide insight into the companies providing such software support and how operators are tapping into that help to better manage their networks and services delivered to customers.


      HetNet Series: Small Cells and Wi-Fi (Spanish by TeleSemana)

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

      Operators are looking at the deployment of small cells and Wi-Fi hotspots in dense urban areas as means to deal with congestion. However, an urban area presents many deployment challenges for this new infrastructure and thus operators will face very different scenarios and many times the experience in one neighborhood may not help to deploy the infrastructure in the next one.

      Deploying and Assuring World-Class Mobile Backhaul

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

      Mobile backhaul plays a key role in customer experience because it links the mobile core to the RAN infrastructure. To ensure the best mobile customer experience, LTE and new mobile services, such as VoIP, mobile video, interactive games and apps, backhaul networks must comply with stringent SLA requirements. In this context, cost-effectively deploying SLA-compliant backhaul networks and ensuring optimal performance during peak load conditions can be very challenging for operators.


      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.


      Measuring the Pulse of Your Network: Assessing Packet-Based Network Synchronization

      By: Thierno Diallo, Bruno Giguère | Category: Carrier Ethernet Networks, Backhaul (OBSAI, CPRI, GigE), Private/Utility

      This webinar explores the current state of synchronization Standards for the synchronization over packet implementations, as well as methods of deployment and the tools and techniques required to assure the successful implementation and ongoing support of such systems.
