Network TAP (Mayeso Ofikira) ndi chipangizo cha hardware chojambulira, kupeza, ndi kusanthula deta yayikulu yomwe ingagwiritsidwe ntchito pa ma network a backbone, ma mobile core network, ma main network, ndi ma IDC network. Ingagwiritsidwe ntchito pojambula magalimoto olumikizana, kubwerezabwereza, kuphatikiza, kusefa, kugawa, ndi kulinganiza katundu. Network Tap nthawi zambiri imakhala yopanda ntchito, kaya yowunikira kapena yamagetsi, yomwe imapanga kopi ya magalimoto a pa intaneti kuti iwunikire ndi kusanthula. Zida zapaintaneti izi zimayikidwa mu ulalo wamoyo kuti zidziwike za kuchuluka kwa magalimoto omwe akuyenda pa ulalowo. Mylinking imapereka yankho lonse la 1G/10G/25G/40G/100G/400G network traffic capture, analytics, management, monitoring for inline security tools and out-of-band monitoring tools.
Zinthu zamphamvu ndi ntchito zomwe Network Tap imachita ndi izi:
1. Kulinganiza katundu wa magalimoto pa intaneti
Kulinganiza katundu kwa maulalo akuluakulu a data kumatsimikizira kulondola ndi kukhulupirika kwa ntchito pazida zakumbuyo ndipo kumasefa magalimoto osafunikira kudzera mu makonzedwe. Kutha kulandira magalimoto omwe akubwera ndikugawa bwino kuzipangizo zosiyanasiyana ndi chinthu china chomwe ma packet broker apamwamba ayenera kugwiritsa ntchito. NPB imakulitsa chitetezo cha netiweki mwa kupereka kulinganiza katundu kapena kutumiza magalimoto ku zida zoyenera zowunikira netiweki ndi chitetezo motsatira mfundo, kuwonjezera kupanga bwino kwa zida zanu zachitetezo ndi zowunikira ndikupangitsa moyo kukhala wosavuta kwa oyang'anira netiweki.
2. Kusefa kwanzeru kwa Network Packet
NPB ili ndi kuthekera kosefera kuchuluka kwa magalimoto pa netiweki kupita ku zida zina zowunikira kuti ikwaniritse bwino kuchuluka kwa magalimoto. Izi zimathandiza mainjiniya a netiweki kusefa deta yomwe ingagwiritsidwe ntchito, zomwe zimapangitsa kuti magalimoto aziyenda bwino, osati kungowonjezera kuchuluka kwa magalimoto, komanso kuthandiza kusanthula mwachangu zochitika komanso kuchepetsa nthawi yoyankha.
3. Kubwereza/Kusonkhanitsa Magalimoto pa Netiweki
Mwa kuphatikiza ma phukusi angapo mu mtsinje umodzi waukulu wa paketi, monga magawo a paketi ndi nthawi, kuti zida zachitetezo ndi zowunikira zigwire ntchito bwino, chipangizo chanu chiyenera kupanga mtsinje umodzi wogwirizana womwe ungatumizidwe ku zida zowunikira. Izi zithandiza kuti zida zowunikira zigwire bwino ntchito. Mwachitsanzo, magalimoto omwe akubwera amabwerezedwanso ndikuwonjezedwa kudzera mu ma interface a GE. Magalimoto ofunikira amatumizidwa kudzera mu mawonekedwe a 10 gigabit ndikutumizidwa ku zida zogwirira ntchito kumbuyo; Mwachitsanzo, madoko 20 a 10-GIGABit (magalimoto onse sapitirira 10GE) amagwiritsidwa ntchito ngati madoko olowera kuti alandire magalimoto omwe akubwera ndikusefa magalimoto omwe akubwera kudzera mu ma port a 10-Gigabit.
4. Kuyerekeza Magalimoto Paintaneti
Magalimoto omwe akusonkhanitsidwa amasungidwa ndikuwonetsedwa ku ma interfaces angapo. Kuphatikiza apo, magalimoto osafunikira amatha kutetezedwa ndikutayidwa malinga ndi momwe akonzedwera. Pa ma node ena a netiweki, chiwerengero cha ma doko osonkhanitsira ndi kusinthira pa chipangizo chimodzi sichikwanira chifukwa cha kuchuluka kwa ma doko omwe akuyenera kukonzedwa. Pankhaniyi, ma pompo angapo a netiweki amatha kusunthidwa kuti asonkhanitse, asonkhanitse, asefe, ndikuyika magalimoto kuti akwaniritse zofunikira zapamwamba.
5. GUI yothandiza komanso yosavuta kugwiritsa ntchito
NPB yomwe mukufuna iyenera kukhala ndi mawonekedwe osinthira -- mawonekedwe ogwiritsira ntchito zithunzi (GUI) kapena mawonekedwe a mzere wolamula (CLI) -- kuti muyang'anire nthawi yeniyeni, monga kusintha kayendedwe ka mapaketi, mapu a madoko, ndi njira. Ngati NPB si yosavuta kuyikonza, kuyiyendetsa, ndi kugwiritsa ntchito, sigwira ntchito yake yonse.
6. Mtengo wa Broker wa Mapaketi
Chinthu chimodzi choyenera kukumbukira pankhani ya msika ndi mtengo wa zida zowunikira zapamwambazi. Ndalama zonse ziwiri zazitali komanso zazifupi zimatha kusiyana kwambiri, kutengera ngati pali zilolezo zosiyanasiyana za madoko komanso ngati ma packet broker amavomereza ma SFP modules aliwonse kapena ma SFP modules okha. Mwachidule, NPB yogwira ntchito bwino iyenera kupereka zonsezi, komanso kuwonekera kwenikweni kwa link-layer ndi microburst buffering, pomwe ikusunga kupezeka kwakukulu komanso kulimba mtima.
Kupatula apo, Network TAPs imatha kukwaniritsa Ntchito Zapadera za Network Business:
1. Kusefa magalimoto a IPv4/IPv6 seven-tuple
2. Malamulo ofananiza zingwe
3. Kuchulukitsa magalimoto ndi kusonkhanitsa anthu
4. Kulinganiza katundu wa magalimoto
5. Kuyerekeza magalimoto pa intaneti
6. Chidindo cha nthawi cha paketi iliyonse
7. Kupereka phukusi
8. Kusefa malamulo kutengera kupezeka kwa DNS
9. Kukonza mapaketi: kudula, kuwonjezera, ndikuchotsa VLAN TAG
10. Kukonza zidutswa za IP
11. Ndege yolumikizira ya GTPv0/ V1 / V2 imagwirizana ndi kayendedwe ka magalimoto pa ndege ya ogwiritsa ntchito
12. Mutu wa ngalande ya GTP wachotsedwa
13. Thandizani MPLS
14. Kutulutsa chizindikiro cha GbIuPS
15. Sonkhanitsani ziwerengero pa mitengo ya mawonekedwe pa gululo
16. Kuthamanga kwa mawonekedwe a thupi ndi mawonekedwe a CHIKWANGWANI CHIMODZI
