Strategically deployed, passive instrumentation on internet access links provides an ideal vantage point to monitor for metrics and KPIs, service flows, and packets for gathering statistics and then analyzing them. Detailed performance views via refined graphs, reports, and tables can be utilized to reduce overall MTTR associated with troubleshooting, traffic engineering, and/or capacity planning for these critical, value-added service links. The analysis of internet services will reveal:

  • Total Internet traffic volume by customer in real-time and over time to identify busiest sites and areas of the network
  • Utilization of different subscriber services and content types, such as streaming voice and audio media, VoIP, web browsing, or email to validate prioritization and routing decisions
  • Hosts, conversations, and response times for specific URLs to troubleshoot HTTP errors

IP MPLS Core Bearer Network
Many telecommunications providers have introduced MPLS-based VPN service offerings to satisfy increasing demands for secure, cost-effective transport of converged voice and application traffic to high-value business customers. As enterprises take advantage of newly introduced services that break out delivery for voice and video into high priority classes and tiered choices for their more latency-tolerant business applications, service providers are challenged to meet service quality expectations.

Again, sophisticated performance monitoring solutions that gather and analyze the collected statistics from MPLS-based VPN networks offer essential services visibility in the form of real-time and historical graphs, reports, and tables that can be used for troubleshooting, traffic engineering, and/or capacity planning purposes. The analysis of traffic flows over MPLS core bearer networks will reveal:

  • Services-aware analysis of utilization and traffic volume across the MPLS core
  • Traffic-flow and response times between individual customers and locations by services such as voice, data, and internet services to troubleshoot problems with valuable new Triple Play offerings
  • In-depth, packet-level details of an individual customer’s activity to analyze and discover the root cause of degradations
  • Bandwidth and services utilization of circuits highlighting individual VRFs to recognize changes in bandwidth or new QoS traffic prioritization schemes that may be needed to accommodate “power user” customers or locations.

It is easy to see the opportunity to increase market share and revenue from fast-rising demand for XoIP services for providers around the world. Reducing customer churn will be the challenge regardless of which technologies are deployed. Having the appropriate visibility into the services delivered, the customers using them, and the network infrastructure delivering them will be an essential part of a successful service delivery strategy. Service providers that embrace customer experience by moving beyond traditional infrastructure-centric approximations of service delivery will be in the best position to retain customers and assure their portion of success within the XoIP services market.
