Marka qalabka Nidaamka Ogaanshaha Faragelinta (IDS) la hawlgeliyo, dekedda muraayadda ee ku taal badhanka xarunta macluumaadka ee dhinaca asxaabta kuma filna (tusaale ahaan, hal deked muraayad ah ayaa loo oggol yahay, dekedda muraayaddana waxay ku jirtay aalado kale).
Waqtigan xaadirka ah, marka aynaan ku darin dekedo badan oo muraayad ah, waxaan isticmaali karnaa qalabka shabakadda ee nuqulka, isku-darka iyo gudbinta si aan ugu qaybinno isla xogta muraayadda qalabkayaga.
Waa maxay Network TAP?
Malaha waxaad markii ugu horreysay maqashay magaca TAP switch. TAP (Terminal Access Point), oo sidoo kale loo yaqaan NPB (Network Packet Broker), ama Tap Aggregator?
Shaqada ugu muhiimsan ee TAP waa in la dejiyo inta u dhaxaysa dekedda muraayadda ee shabakadda wax soo saarka iyo kooxda qalabka falanqaynta. TAP waxay ururisaa taraafikada muraayadda leh ama kala go'an ee ka timaadda hal ama in ka badan aaladaha shabakadda wax soo saarka waxayna gaadiidka u qaybisaa hal ama in ka badan aaladaha falanqaynta xogta.
Xaaladaha dejinta shabakadda TAP ee caadiga ah
Network Tap waxay leedahay calaamado cad, sida:
Qalabka Madaxa-bannaan
TAP waa qalab gaar ah oo aan saameyn ku yeelan culayska qalabka shabakadda ee jira, taas oo ah mid ka mid ah faa'iidooyinka marka loo eego muraayadda dekedda.
Beddel?
Shabakad Taabasho?
Shabakad Hufan
Ka dib marka TAP lagu xiro shabakadda, dhammaan aaladaha kale ee shabakadda saameyn kuma yeelanayaan. Iyaga, TAP-gu waa mid hufan sida hawada, aaladaha la socodka ee ku xiran TAP-na waa kuwo hufan oo u muuqda shabakadda guud ahaan.
TAP waxay la mid tahay Port Mirroring oo ku jirta badhanka. Haddaba maxaa loo adeegsadaa TAP gooni ah? Aan eegno qaar ka mid ah farqiga u dhexeeya Network TAP iyo Network Port Mirroring.
Farqiga 1aad: Shabakadda TAP way ka fududahay in la habeeyo marka loo eego muraayadda dekedda
Muraayadda dekeddu waa in lagu habeeyaa badhanka. Haddii la socodka loo baahan yahay in la hagaajiyo, badhanka waa in dib loo habeeyaa DHAMMAAN. Si kastaba ha ahaatee, TAP-ku wuxuu u baahan yahay oo keliya in la hagaajiyo meesha uu codsaday, taas oo aan saameyn ku yeelanayn aaladaha shabakadda ee jira.
Farqiga 2aadTAP-ka Shabakadda saameyn kuma yeesho waxqabadka shabakadda marka loo eego muraayadda dekedda
Muraayadda dekedda ee badhanka ayaa hoos u dhigaysa waxqabadka badhanka waxayna saameysaa awoodda wareejinta. Gaar ahaan, haddii badhanka lagu xiro shabakad taxane ah oo khadka ah, awoodda gudbinta ee shabakadda oo dhan si weyn ayay u saamaysaa. TAP waa qalab madax-bannaan mana waxyeelayso waxqabadka qalabka sababtoo ah muraayadda taraafikada. Sidaa darteed, wax saameyn ah kuma yeelanayso culayska aaladaha shabakadda ee jira, taas oo leh faa'iidooyin waaweyn marka loo eego muraayadda dekedda.
Farqiga 3aadShabakadda TAP waxay bixisaa habka taraafikada oo dhammaystiran marka loo eego nuqulka muraayadda dekedda
Muraayadda dekeddu ma hubin karto in dhammaan taraafikada la heli karo sababtoo ah dekedda is-beddelka lafteedu waxay shaandheyn doontaa qaar ka mid ah xirmooyinka khaladaadka ama baakadaha cabbirka aadka u yar. Si kastaba ha ahaatee, TAP waxay hubisaa daacadnimada xogta sababtoo ah waa "ku-celcelin" dhammaystiran oo ku jirta lakabka jireed.
Farqiga 4aadDib u dhaca gudbinta TAP waa ka yar yahay kan Port Mirroring
Qaar ka mid ah furayaasha hoose, muraayadda dekeddu waxay keeni kartaa dib u dhac marka la koobiyaynayo taraafikada dekedaha muraayadda leh, iyo sidoo kale marka la koobiyaynayo dekedaha 10/100m dekedaha Giga Ethernet.
Inkasta oo arrintan si weyn loo diiwaangeliyey, waxaan aaminsanahay in labada falanqayn ee dambe aysan lahayn taageero farsamo oo xooggan.
Haddaba, xaaladdee guud ahaan, waxaan u baahanahay inaan u isticmaalno TAP qaybinta taraafikada shabakadda? Si fudud, haddii aad leedahay shuruudaha soo socda, markaa Network TAP waa doorashadaada ugu fiican.
Tiknoolajiyada TAP ee Shabakadda
Dhageyso waxa kor ku xusan, dareem in shunt-ka shabakadda TAP uu runtii yahay aalad sixir ah, shunt-ka suuqa hadda jira ee TAP oo la isticmaalo qaab-dhismeedka hoose ee qiyaastii saddex qaybood:
FPGA
- Waxqabad sare
- Way adag tahay in la horumariyo
- Kharash sare
MIPS
- Dabacsan oo ku habboon
- Dhibaato horumar oo dhexdhexaad ah
- Iibiyeyaasha ugu muhiimsan RMI iyo Cavium waxay joojiyeen horumarinta waxayna ku guuldareysteen markii dambe
ASIC
- Waxqabad sare
- Horumarinta shaqada ballaarinta way adag tahay, badanaa sababtoo ah xaddidaadaha jajabka laftiisa
- Is-dhexgalka iyo qeexitaannada waxaa xaddidaya chip-ka laftiisa, taasoo keentay waxqabad ballaarin liidata
Sidaa darteed, cufnaanta sare iyo xawaaraha sare ee Network TAP ee suuqa lagu arko waxay leedahay meel badan oo lagu hagaajin karo dabacsanaanta isticmaalka wax ku oolka ah. Shunters-ka shabakadda TAP waxaa loo isticmaalaa beddelka hab-maamuuska, ururinta xogta, shunting-ka xogta, muraayadaynta xogta, iyo shaandhaynta taraafikada. Noocyada dekedda ee ugu badan ee caadiga ah waxaa ka mid ah 100G, 40G, 10G, 2.5G POS, GE, iwm. Sababtoo ah ka bixitaanka tartiib tartiib ah ee alaabada SDH, shunters-ka Shabakadda TAP ee hadda jira waxaa inta badan loo isticmaalaa jawiga shabakadda oo dhan ee Ethernet.
