Masiku ano, momwe intaneti ilili paliponse, ndikofunikira kukhala ndi njira zodzitetezera zolimba kuti ogwiritsa ntchito asalowe m'mawebusayiti omwe angakhale oipa kapena osayenera. Njira imodzi yothandiza ndiyo kukhazikitsa Network Packet Broker (NPB) kuti iwunikire ndikulamulira kuchuluka kwa anthu omwe amabwera pa intaneti.
Tiyeni tikambirane za momwe NPB ingagwiritsidwire ntchito pa izi:
1- Wogwiritsa ntchito amalowa patsamba lawebusayiti: Wogwiritsa ntchito amayesa kulowa patsamba lawebusayiti pogwiritsa ntchito chipangizo chake.
2- Mapaketi omwe amadutsa amabwerezedwanso ndiKudina Kopanda MphamvuPamene pempho la wogwiritsa ntchito likudutsa pa netiweki, Passive Tap imabwerezanso mapaketiwo, zomwe zimathandiza NPB kusanthula kuchuluka kwa magalimoto popanda kusokoneza kulumikizana koyambirira.
3- Network Packet Broker imatumiza anthu otsatirawa ku Policy Server:
- HTTP PEZANPB imazindikira pempho la HTTP GET ndikulitumiza ku Policy Server kuti liwunikidwenso.
- HTTPS TLS Client Moni: Pa kuchuluka kwa anthu omwe akuyenda pa HTTPS, NPB imagwira paketi ya TLS Client Hello ndikuitumiza ku Policy Server kuti idziwe tsamba lawebusayiti lomwe mukufuna.
4- Policy Server imayang'ana ngati tsamba lawebusayiti lomwe lapezeka lili pamndandanda wakuda: Seva ya Ndondomeko, yokhala ndi database ya mawebusayiti odziwika kuti ndi oipa kapena osafunikira, imafufuza ngati tsamba lofunsidwalo lili pamndandanda wakuda.
5- Ngati tsamba lawebusayiti lili pamndandanda wakuda, Policy Server imatumiza phukusi la TCP Reset:
- Kwa wogwiritsa ntchito: Seva ya Ndondomeko imatumiza phukusi la TCP Reset lomwe lili ndi IP yoyambira ya tsamba lawebusayiti ndi IP yopita kwa wogwiritsa ntchito, zomwe zimapangitsa kuti kulumikizana kwa wogwiritsa ntchito ku tsamba lawebusayiti lomwe laletsedwa kuthe.
- Ku webusayiti: Policy Server imatumizanso paketi ya TCP Reset yokhala ndi IP yoyambira ya wogwiritsa ntchito ndi IP yopita patsamba lawebusayiti, ndikudula kulumikizana kuchokera mbali ina.
6- Kuwongolera kwa HTTP (ngati anthu ambiri ndi HTTP)Ngati pempho la wogwiritsa ntchito linaperekedwa kudzera pa HTTP, Policy Server imatumizanso HTTP redirect kwa wogwiritsa ntchito, kumutumiza ku tsamba lotetezeka komanso losiyana.
Pogwiritsa ntchito njira imeneyi pogwiritsa ntchito Network Packet Broker ndi Policy Server, mabungwe amatha kuyang'anira bwino ndikuwongolera mwayi wopeza mawebusayiti omwe ali ndi anthu omwe sanawagwiritse ntchito, kuteteza maukonde awo ndi ogwiritsa ntchito ku ngozi zomwe zingachitike.
Wogulitsa Mapaketi a Pakompyuta (NPB)imabweretsa magalimoto ochokera ku magwero osiyanasiyana kuti asefedwe kuti athandize kuyendetsa bwino kuchuluka kwa magalimoto, kudula magalimoto, ndi kuthekera kobisa. Ma NPB amathandizira kuphatikiza magalimoto a pa intaneti ochokera ku magwero osiyanasiyana, kuphatikiza ma rauta, ma switch, ndi ma firewall. Njira yophatikiza iyi imapanga mtsinje umodzi, zomwe zimapangitsa kuti kusanthula ndi kuyang'anira zochitika za pa intaneti kukhale kosavuta. Zipangizozi zimathandizanso kusefa magalimoto a pa intaneti, zomwe zimathandiza mabungwe kuyang'ana kwambiri deta yoyenera pakuwunika komanso chitetezo.
Kuwonjezera pa luso lawo lophatikiza ndi kusefa, ma NPB amawonetsa kugawa kwanzeru kwa magalimoto a pa intaneti kudzera mu zida zambiri zowunikira ndi chitetezo. Izi zimatsimikizira kuti chida chilichonse chimalandira deta yofunikira popanda kuwadzaza ndi zambiri zakunja. Kusinthasintha kwa ma NPB kumaphatikizapo kukonza kuyenda kwa magalimoto a pa intaneti, mogwirizana ndi luso lapadera ndi mphamvu za zida zosiyanasiyana zowunikira ndi chitetezo. Kukonza kumeneku kumalimbikitsa kugwiritsa ntchito bwino zinthu zonse mu zomangamanga za netiweki.
Ubwino waukulu wa Network Packet Broker wa njira iyi ndi monga:
- Kuwonekera Kwathunthu: Kuthekera kwa NPB kubwerezabwereza kuchuluka kwa anthu omwe ali pa netiweki kumalola kuti pakhale mawonekedwe athunthu a kulumikizana konse, kuphatikiza kuchuluka kwa anthu omwe ali pa HTTP ndi HTTPS.
- Kulamulira kwa Granular: Kuthekera kwa Policy Server kusunga mndandanda wakuda ndikuchitapo kanthu, monga kutumiza mapaketi a TCP Reset ndi ma redirects a HTTP, kumapereka ulamuliro waukulu pa mwayi wopeza mawebusayiti osafunikira kwa ogwiritsa ntchito.
- Kuchuluka kwa kukula: Kusamalira bwino kuchuluka kwa anthu omwe ali pa netiweki kumatsimikizira kuti njira yotetezerayi ikhoza kukulitsidwa kuti ikwaniritse zosowa za ogwiritsa ntchito zomwe zikuchulukirachulukira komanso zovuta za netiweki.
Pogwiritsa ntchito mphamvu ya Network Packet Broker ndi Policy Server, mabungwe amatha kulimbitsa chitetezo cha netiweki yawo ndikuteteza ogwiritsa ntchito awo ku zoopsa zokhudzana ndi kulowa m'mawebusayiti omwe ali ndi mndandanda wakuda.
