New high bandwidth, real-time services such as VoIP, VoD and IPTV stress IP network infrastructures and require high QoS (Quality of Service) and QoE (Quality of Experience). VoIP calls must sound as good as land-line service, IPTV must be absent of pixelation, blurring, or frozen frames, high-speed Internet services must appear responsive. However, the task becomes difficult to achieve because the IP network is best effort in nature with unpredictable routing and traffic changes over time and is made up of isolated domains with no cross-domain control. It is complex and is often maintained through human intervention. Oftentimes the end user becomes the monitoring system putting operators in a “reactive mode”, resulting in angry customers. With little information on end user QoE and network QoS, quality problems cannot be quickly fixed and high operation costs could be incurred for each truck roll. Service carries high Service Level Agreement (SLA) penalties for network providers. Merely adding bandwidth is not a feasible solution any more.

Data center solutions are our first priority. The above factors combining with the following additional forces create an urgent demand for solutions: tremendous growth in traffic and web based applications, vulnerability to attacks, congestion and equipment failures, static path selection, exploding complexity due to the growing number of appliances and band-aids type of upgrades, service interruptions with manual management and high ISP peering cost and poor performance. Data center operators solve the above problems today by over-provisioning bandwidth and/or hiring additional employees.

CertusNet believes that IP networks need to be self-managing, self-diagnosing, self-healing and self-optimizing for large scale deployment of real time QoS-sensitive applications. Its mission is to provide service assurance and application delivery for IP networks through real-time end-to-end traffic and service control. It offers visibility into underlying network infrastructure, traffic content, and end-customer experience, and takes proactive action to optimize the service path, and solve or mitigate problems automatically before customers complain.
