The SD-WAN market is growing fast, but so is competition. In such a competitive environment, SD-WAN vendors need to offer products with unique features and capabilities in order to stand out. Real-time application visibility powered by deep packet inspection (DPI) software can be the decisive element in achieving them.
This whitepaper highlights the key value of DPI software, which is enabling advanced SD-WAN analytics and security features.
DPI software is made to inspect packets at high wire speeds and a critical factor is the throughput and resources required. Keeping the amount of resources that integrated DPI and application classification technology requires low is critical. The fewer cores (on a multi-core processor) and the less on-board memory an engine needs, the better. Multi-threading provides almost linear scalability on multi-core systems. In addition, highly-optimized flow tracking is required for handling millions of concurrent subscribers.
When your solution needs deep packet inspection (DPI) application awareness as a key enabling feature, highly reliable and accurate identification of network traffic and applications - in real time - is an expected requirement. Whether itís for software defined networks to enable policy control and critical traffic steering or to protect corporate networks, IoT devices, and cloud platforms from malicious attacks, itís crucial to choose the right DPI solution.
According to many market research analysts, the global wireless access point (WAP) market is anticipated to continue its upward trajectory and to grow at an impressive compound annual growth rate (CAGR) of approximately 8% through 2020. Many enterprises are utilizing cloudcomputing technology for cost-cutting purposes, eliminating investments required for storage hardware and other physical infrastructures. With significant growth expected in Internet usage, particularly bandwidth consuming video traffic, WAP vendors need to enable their customers to monitor and improve device performance, improve end user experience, and enhance security. These customers include general enterprises that offer Internet access to patrons like airports, hotels, retail / shopping centers and so on. These external Internet access providers can differentiate themselves by offering optimum service through advanced network analytics, traffic shaping, application control, security capabilities and more.
When Barracuda first engaged with Rohde & Schwarz Cybersecurity in 2007, enterprises were more concerned about the unauthorized use of Skype, other P2P applications and instant messaging. Although the need for application control and awareness remains, enterprise concerns are shifting to securing enterprise applications hosted in private and public clouds, protecting east-west data center traffic and preventing unwanted traffic and malware on the corporate network.
In its quest to continue increasing market share, American Financial Services (AFS) began to realize the importance of a solid analytics package to help develop and track a list of targeted keywords in several pay-per-click search engines. Additionally the highly competitive nature of their most popular keywords was creating a considerable marketing challenge.
