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.

AOS delivers powerful, intent-driven automation of network services in vendor-agnostic environments by delivering it as an easily consumable service in response to consumer-specified intent. Network devices serve packets, AOS services serve application workloads.
According to numerous studies, 70-80% of outages are due to configuration change applied to a living system, and not due to initial deployment. Initial, one-time deployment can be seen as sort of a “hello world” application; the real complexities arise as the system evolves. With AOS, configuration, telemetry, and expectations are derived from the single source of truth - the intent - in an idempotent fashion, and as such there is no implementation difference between initial deployment or change management.
Explore the optimization tools that give you the ability to see and control the performance and security of your WAN traffic, a vital component to your cloud success. Among other things, these tools help you counteract the effects of latency introduced by geographical WAN distances and allow you to alleviate network congestion that might results from sending a lot large files and retransmitting dropped packets.
Computer networks are built to facilitate the flow of communication, not stop it. Unfortunately, data packets can be manipulated to look normal yet contain an exploit. These techniques evade standard security measures and, in most cases, can deliver a malicious payload without detection. Often, these advanced evasion techniques (AETs) take advantage of rarely used protocol properties in unexpected combinations. Most network security devices are not capable of detecting them. While many pass industry tests with high ratings, those ratings are based on protection against a limited number of threats. The exact number of AETs is unknown, but it is close to hundreds of millions. To defend against AETs, your network security should incorporate seven critical features into your next gen firewall.

The need to understand how the performance and problems within the technical infrastructure impacts the capabilities of the business is massive. However, the majority of companies can only measure application and specific asset performance, whereas many issues within the infrastructure lie at the transport level, where packet switching presents both great opportunities and major issues.
