Deep packet inspection (DPI) is a form of filtering used to inspect data packets sent from one computer to another over a network. DPI is a sophisticated method of packet filtering that operates at the seventh layer (the application layer) of the Open System Interconnection (OSI) reference model. The effective use of DPI enables its users to track down, identify, categorize, reroute or stop packets with undesirable code or data.
DPI is normally more effective than typical packet filtering, which inspects only the packet headers. DPI inspects the packet's data part (and sometimes the packet header) when it goes over an inspection point, attempting to find protocol noncompliance, intrusions, spam, viruses or other predefined factors to determine whether the packet can pass or whether it must be directed to another location. With DPI, organizations can boost their network management systems without investing heavily in core network technologies.
According to QYResearch’s research, The global Deep Packet Inspection (DPI) market size is projected to reach US$ 17281.78 million by 2027, from US$ 3741.55 million in 2020, at a CAGR of 24.36% during 2021-2027.
The increasing necessity for DPI will be spurred by growing subscriber demand for mobile content and applications, coupled with the network operators’ need to control usage, cost and create new personalized services. Growth will be aided in part by: Increase in global broadband users, Mobile network operators have made significant investments in new technology to increase network performance and alleviate bandwidth congestion. Competitive pressure across network operators – The competition among network operators continues to increase as they battle for the latest generation of broadband users and seek to capture new revenue opportunities.
The key players globally are Cisco Systems, International Business Machine (IBM), Intel, NortonLifeLock (Symantec), Palo Alto Networks, Check Point Software Technologies, Extreme Networks, Netscout Systems, Procera Networks(Sandvine), Viavi Solutions, Allot Communications, Bivio Networks, Cpacket Networks and so on.
The leading companies own the advantages on better performance, more abundant product’s types, better technical and impeccable after-sales service. Consequently, they take the majority of the market share of high-end market. Looking to the future years, the slow downward price trend in recent years will maintain. As competition intensifies, prices gap between different brands will go narrowing. Similarly, there will be fluctuation in gross margin.
The industry is expected to remain innovation-led, with frequent acquisitions and strategic alliances adopted as the key strategies by the players to increase their industry presence. Significant and lasting barriers make entry into this market difficult. These barriers include, but are not limited to: (i) product development costs; (ii) capital requirements; (iii) intellectual property rights; (iv) Regulatory requirement; and (v) Transitions’ unfair methods of competition.
