M'mawonekedwe amakono a digito, komwe intaneti imapezeka paliponse, ndikofunikira kukhala ndi njira zotetezeka zoteteza ogwiritsa ntchito kuti asalowe mawebusayiti omwe angakhale oyipa kapena osayenera. Yankho limodzi lothandiza ndikukhazikitsa Network Packet Broker (NPB) kuyang'anira ndikuwongolera kuchuluka kwa ma network.
Tiyeni tidutse zochitika kuti timvetsetse momwe NPB ingathandizire pazifukwa izi:
1- Wogwiritsa amalowa patsamba: Wogwiritsa amayesa kupeza tsamba lawebusayiti kuchokera pazida zawo.
2- Mapaketi omwe amadutsa amafananizidwa ndi aPassive Tap: Pamene pempho la wogwiritsa ntchito likuyenda pa intaneti, Passive Tap imabwereza mapaketi, kulola NPB kusanthula magalimoto popanda kusokoneza kulankhulana koyambirira.
3- Network Packet Broker imapititsa patsogolo magalimoto otsatirawa ku Policy Server:
- HTTP GET: NPB imazindikira pempho la HTTP GET ndikutumiza ku Policy Server kuti iwunikenso.
- Makasitomala a HTTPS TLS Moni: Pazambiri za HTTPS, NPB imagwira paketi ya Client Hello ya TLS ndikuitumiza ku Policy Server kuti idziwe komwe mukupita.
4- Policy Server imayang'ana ngati tsamba lomwe mwapeza lili pamndandanda wakuda: Policy Server, yokhala ndi nkhokwe ya mawebusayiti odziwika oyipa kapena osayenera, imayang'ana ngati tsamba lomwe lafunsidwa lili pamndandanda woletsedwa.
5- Ngati webusayiti ili pamndandanda wakuda, Seva ya Policy imatumiza paketi ya TCP Reset:
- Kwa wogwiritsa ntchito: Seva ya Policy imatumiza paketi ya TCP Reset yokhala ndi IP yochokera patsambali komanso IP yofikira kwa wogwiritsa ntchito, kuletsa kulumikizidwa kwa wogwiritsa ntchito patsamba loletsedwa.
- Ku webusayiti: Seva ya Policy imatumizanso paketi ya TCP Reset yokhala ndi IP yochokera kwa wogwiritsa ntchito komanso IP yopita patsamba lawebusayiti, ndikudula kulumikizana kuchokera kumalekezero ena.
6- HTTP yolozeranso (ngati magalimoto ali HTTP): Ngati pempho la wogwiritsa ntchito lidapangidwa pa HTTP, Seva ya Policy imatumizanso kuwongolera kwa HTTP kwa wogwiritsa ntchito, kuwalozera ku tsamba lotetezeka, lina.
Pogwiritsa ntchito yankholi pogwiritsa ntchito Network Packet Broker ndi Policy Server, mabungwe amatha kuyang'anira bwino ndikuwongolera mwayi wogwiritsa ntchito mawebusaiti oletsedwa, kuteteza maukonde awo ndi ogwiritsa ntchito kuvulazidwa.
Network Packet Broker (NPB)zimabweretsa kuchuluka kwa magalimoto kuchokera kumagwero angapo kuti zisefe zina zowonjezera kuti zithandizire kuwongolera kuchuluka kwa magalimoto, kudula kwa magalimoto, ndi kuthekera kwa masking. Ma NPB amathandizira kuphatikizika kwa magalimoto apaintaneti ochokera kumagwero osiyanasiyana, kuphatikiza ma routers, ma switch, ndi ma firewall. Kuphatikizika kumeneku kumapangitsa kuti pakhale mtsinje umodzi, kufewetsa kusanthula kotsatira ndi kuyang'anira ntchito zapaintaneti. Zipangizozi zimathandiziranso kusefa komwe kumayendera pamanetiweki, zomwe zimapangitsa kuti mabungwe aziyang'ana pazomwe zili zofunika pakuwunika komanso chitetezo.
Kuphatikiza pa kuphatikizika kwawo ndi kuthekera kwawo kusefa, ma NPB amawonetsa kugawa kwanzeru kwamagalimoto pama network pazida zingapo zowunikira ndi chitetezo. Izi zimatsimikizira kuti chida chilichonse chimalandira deta yofunikira popanda kudzaza ndi chidziwitso chakunja. Kusinthika kwa ma NPB kumafikira pakukhathamiritsa kuyenda kwa magalimoto apaintaneti, kugwirizanitsa ndi kuthekera kwapadera ndi kuthekera kwa zida zosiyanasiyana zowunikira ndi chitetezo. Kukhathamiritsa uku kumalimbikitsa kugwiritsidwa ntchito moyenera kwa zinthu pamanetiweki onse.
Ubwino waukulu wa Network Packet Broker wanjira iyi ndi monga:
- Kuwonekera kwathunthu: Kuthekera kwa NPB kutengera kuchuluka kwa magalimoto pamaneti kumalola kuwona kwathunthu kulumikizana konse, kuphatikiza magalimoto onse a HTTP ndi HTTPS.
- Granular Control: Kuthekera kwa Policy Server kusungitsa mndandanda wakuda ndikuchita zomwe mukufuna, monga kutumiza mapaketi a TCP Reset ndi kuwongoleranso kwa HTTP, kumapereka kuwongolera pang'ono kwa ogwiritsa ntchito mawebusayiti osayenera.
- Scalability: Kugwiritsa ntchito bwino kwa NPB kwa magalimoto apaintaneti kumatsimikizira kuti yankho lachitetezoli litha kukulitsidwa kuti ligwirizane ndi zomwe ogwiritsa ntchito akukula komanso zovuta zama network.
Pogwiritsa ntchito mphamvu ya Network Packet Broker ndi Policy Server, mabungwe amatha kupititsa patsogolo chitetezo chawo pa intaneti ndikuteteza ogwiritsa ntchito awo ku zoopsa zomwe zimadza chifukwa cholowa mawebusayiti osaloledwa.
