Joale, DPI (tlhahlobo ea boitšoaro bo tebileng) e sebetsa ho NPB:
1). Patlisiso ea Packet: NPB e nkeloa sebaka sa marang-rang ho tsoa mehloling e fapaneng, e kang switch, e re, routers, li-toutes. E fumana lipakete e tšela marang-rang.
2). Pakete ea pakete: Lipakete tse hapiloeng li pakiloe ke NPB ho nts'etsapele likarolo tse fapaneng tsa protocol le data e amanang le eona. Ts'ebetso ena ea ho ipalla e thusa ho tseba likarolo tse fapaneng har'a lihlooho tse kang li-iP, lijalo tsa sehlopha (mohlala, li-protocol tsa sekhukhu.
3). Tlhahlobo ea tefo: Ka DPI, NPB, NPB e ke ke ea lekola tlhahlobo ea hlooho 'me e shebane le moputso oa' nete ka har'a lipakete. E hlahloba litaba tsa chelete ka botebo, e sa hlole ka kopo kapa protocol e sebelisitsoeng, ho ntša tlhaiso-leseling e nepahetseng.
4). Boitsebiso ba protocol: DPI e nolofalletsa NPB ho tsebahatsa li-protocol tse khethehileng le likopo tse sebelisoang kahare ho sephethephethe sa marang-rang. E ka bona le ho khetholla protocol joalo ka http, FTP, SMTP, DNS, VNS, VNS, Protocols.
5). Tlhahlobo ea litaba: DPI e lumella NPB ho lekola litaba tsa lipakete bakeng sa lipaterone tse itseng, li-signature, kapa mantsoe a bohlokoa. Sena se nolofalletsa ho fumanoa ha litšokelo tsa litšokelo tsa marang-rang, joalo ka malware, vaerase, liteko tsa enjene, kapa lintho tse belaetsang.

6). Metadaa Exction: Nakong ea DPI, NPB e bua ka metadata e amehang lipakeng. Sena se ka kenyelletsa tlhaiso-leseling e joalo ka mohloli le liaterese tsa IP, linomoro tsa Port, lintlha tsa thuto, data efe kapa efe e nepahetseng.
7).
