Time to ReThink
The Napatech Time to ReThink series provides a number of briefs outlining specific challenges for different types of network appliance applications. The insights provided in each brief are based on Napatech experience with over 100 OEM customers in production today and the challenges they are facing every day. The briefs are designed to be both educational and inspirational to help network appliance designers make the right choices in the face of rising demands.
Time to ReThink SDN and NFV
Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are gathering momentum as telecom carriers struggle to manage rapid growth in data traffic. Discussions have focused on the ability of SDN and NFV to make network and service provisioning more agile and flexible. But, do they fully address the challenge facing carriers today? Only by enabling real-time insight into what is happening in the network, and how services are performing, will the true benefits of SDN and NFV be realized.

Time to ReThink Appliance Portfolio Development
A network appliance is a stand-alone, dedicated device or system that focuses on a particular networking task, such as monitoring, test and measurement, optimization or security. The traditional approach has been to develop an appliance with a particular application, at a specific port speed and deploy the appliance to monitor one point in the network. However, the relentless increase in data speed and complexity is driving appliance developers to rethink their portfolio development strategies using universal network appliances.

Time to ReThink Real-Time Big Data Analytics
Real-Time Big Data Analytics (RTBDA) has emerged as a new topic in big data discussions. The concepts underpinning RTBDA can be applied in a telecom context, but it does require a rethink on what is “real time” and what sources of information can support a RTBDA strategy. Fortunately, the technologies required to implement such a strategy are not only available, but in many cases already being used, just not as effectively or strategically as they could be.

Time to ReThink Appliance Throughput
Napatech intelligent adapters and standard servers provide
network appliance vendors with a powerful platform for system throughput.
Napatech can now demonstrate system throughputs of 100 Gbps off-line and 80
Gbps in-line. This provides a flexible and easily deployable solution for
appliance vendors that monitor, test, secure, or optimize networks and

Time to ReThink Mobile Network Analysis
The combination of Napatech intelligent adapters, DPI
software and COTS hardware provides Telecom Equipment Manufacturers (TEMs) with
a powerful platform for real-time network analysis. TEMS can thus enable carriers
to provide innovative services and superior quality of experience, thereby
increasing revenue while experiencing explosive growth in mobile data traffic.

Time to ReThink Network Security
Three current trends—cloud computing, big data analysis and mobility—threaten network security. All three promise efficiency and convenience, but they also expose the network to critical vulnerabilities through centralized data and less controlled access. Napatech proposes a holistic solution based on analysis of network and security information.

Time to ReThink Guaranteed Delivery
Guaranteed packet capture ensures that all data is collected in real-time with zero packet loss, but this is no longer enough. To assure zero packet loss for the analysis application,the network appliance needs to be designed for guaranteed delivery.

Time to ReThink Performance Monitoring
New requirements for application awareness and support for unified communications are challenging performance monitoring appliance vendors to reconsider their approach. Flexibility and scalability are key requirements. At the same time, new opportunities can be realized by expanding monitoring capabilities to include new usage scenarios

Time to ReThink Time Precision and Accuracy
For effective network monitoring, analysis, test and measurement precise Ethernet frame time stamping and accurate time synchronization is essential. As line rates increase the challenge for OEM appliance vendors is ensuring continued precision and accuracy. What are the technology choices available and which of these can help in meeting these challenges?

Time to ReThink Network Management
Telecom network management has traditionally focused on polling mechanisms to provide snapshots of network events. As network data speeds and volumes accelerate, especially in mobile data networks, it is time to rethink how network management is performed and the solutions that are needed to scale with future demand.
