Encrypted traffic visibility with next-gen DPI

Encryption is rapidly becoming synonymous with network security and privacy. However, encryption presents challenges in the form of diminished network visibility and control which can be disruptive to networks that are highly reliant on deep network insights into managing and securing their data and assets. This whitepaper reviews encryption protocols, loss of traffic visibility and the associated adverse impact on network functionalities. It provides insights on how the incorporation of encypted traffic intelligence (ETI), including cutting-edge ML / DL techniques, circumvents the limitations associated with conventional deep packet inspection.

Session and subscriber awareness in mobile core networks

While general traffic awareness grants IP network operators an overview of the network, subscriber awareness goes a step further by unearthing deeper insights on the subscriber level. This whitepaper explains why subscriber awareness plays a key role in the management of networks and how vendors of network packet brokers and other equipment, as well as mobile operators, are able to enhance the performance of their network functions by incorporating the OEM software module R&S®GSRM.

ipoque tests deep packet inspection for 5G networks

Deep packet inspection (DPI) is a critical element of 4G/5G wireless networks as it is mandatory for application awareness and flow prioritization for proper service delivery and high quality of experience. Tests of R&S®PACE 2 DPI show a significant performance increase on Intel® Xeon® Scalable processor-based servers when upgrading to a new CPU. This demonstrates the different impact on performance of aligned vs misaligned non-uniform memory access (NUMA) in dual socket systems.

DPI for application performance monitoring

In a world dominated by real-time applications, network insights are critical for both network service providers and enterprises to ensure that applications continue to deliver the experience and service levels expected by users. Deep packet inspection (DPI) technology, embedded in APM solutions, provides the network intelligence needed to manage application performance, determining root causes of performance issues, detecting inappropriate traffic and security risks, and reacting to network slowdowns before they impact end users.

DPI and 5G

DPI’s granular classification capabilities help network operators manage an array of new applications and services introduced by 5G. Application awareness and detailed traffic analytics are key for various network services to support 5G's features, such as network slicing and edge computing. Deep packet inspection technology empowers real-time traffic classification, feeding information into the network to support the implementation of these advanced features.

Deep packet inspection

Deep packet inspection has been an essential component of information technology networks for well over two decades. Internet traffic volume and encrypted traffic rates have increased exponentially over the years. At the same time, DPI software has evolved into a powerful tool to meet new network challenges and plays a vital role in today's internet and network infrastructures. With expanding technologies such as cloud computing, 5G or the internet of things (IoT), DPI-enabled protocol and application awareness is becoming even more important for networks.

DPI for vEPC vendors

Deep packet inspection (DPI) is the key for virtualized evolved paket core (vEPC) solutions vendors to truly improve competitive service differentiation. With DPI they can transform markets focused on network agility, intelligence and automation. Embedded in service chains and network slices, DPI supports real-time analytics and quality of experience. This includes visualization and reports on application performance and security diagnostics for network and service operations.

SD-WAN and DPI

The SD-WAN market is growing fast, but so is competition. In order to stand out in such a competitive environment, SD-WAN vendors need to offer products with unique features and capabilities. Real-time application visibility powered by deep packet inspection (DPI) software can be the decisive element in achieving them.

Why network security requires deep packet inspection

What is needed to identify, investigate and block attacks in this ever-changing threat landscape? The answer is deep visibility into network traffic, up to the application layer and beyond, as provided by the advanced OEM DPI engine R&S®PACE 2. For network security vendors to help customers effectively block and mitigate threats, this visibility is a critical prerequisite for the stability and reliability of modern cybersecurity solutions.
