Chinhu chakakosha icho vatengi vanofanirwa kutarisa muNPB is is is is is-yekuvhara kudzokera kumashure.
Network packet broker inofanirwa kukwanisa kusangana yakazara traffic traffic yechiteshi chimwe nechimwe pane chishandiso. MuCassis system, kushamwaridzana nedzidzo yekudzoreredza kunofanirawo kuve nekugona kuzere kwetraffic traffic yeiyo yakabatana module. Kana iyo NPB ichidonha chikanda, izvi zvishandiso hazvizove nekunzwisisa kwakazara kwe network.
Kunyangwe huwandu hwakawanda hweNPB hwakavakirwa pane eic kana FPGA, nekuda kwechokwadi chePaketi yekugadzirisa maitiro, iwe uchawana zvakawanda zvibvumirano kana cpus inogamuchirika (kuburikidza module). Iyo MyLinking ™ network packet broker (NPB) yakavakirwa pamhinduro yeAsia. Izvi kazhinji kazhinji chinhu chinopa shanduko inochinjika uye saka haigone kuitwa zvakachena muHardware. Izvi zvinosanganisira kudengenyeka kwepaketi, timestamps, ssl / tls decryption, keyword search, uye yenguva dzose kutaura kwekutsvaga. Izvo zvakakosha kuti uzive kuti kushanda kwayo kunoenderana nekuita kweCPU. (Semuenzaniso, nguva dzose inotsvaga yekutsvaga maitiro akafanana inogona kubereka zvakaringana zviitiko zvichienderana nemhando yemotokari, kufananidza chiyero, uye saka hazvisi nyore kuona usati waita chairo chaicho.
Kana iyo CPU-Inotsvaga maficha akagoneswa, ivo vanova chinhu chinodzikisira mukuita zvakazara kweNPB. Advent yeCPUS uye yakarongwa ichichinja machipisi, yakadai sekaveni Xpliant, isina kujairika network-yechiitiko chevamiriri vepamusoro Pakati pezvinyorwa zvepamberi zvataurwa pamusoro apa, keyword uye yenguva dzose kutaura kwekutsvaga mienzaniso yakanaka yeinotevera-chizvarwa kugona. Iko kugona kwekutsvaga paPacket kubhadhara mikana yekuvhara traffic pachirongwa uye zviyero zvekushandisa, uye zvinopa zvakadzama kudzora pamusoro peneti yekushanduka kupfuura iyo l2-4.
Network packet broker inokodzera sei mukuzvivara?
Iyo NPB inogona kuiswa mune yakasungirirwa network nenzira mbiri dzakasiyana:
1- Inline
2- Out-ye-bhendi.
Maitiro ega ega ane zvakanakira uye zvakaipa uye anogonesa kutevedzera traffic munzira iyo dzimwe nzira dzisingakwanise. Iyo Inline Network Packet Broker ine chaiyo-nguva network traffic traffic iyo inofamba nemushini munzira yaro kuenda kunzvimbo yayo yekuenda. Izvi zvinopa mukana wekunyengedza traffic munguva chaiyo. Semuenzaniso, kana uchiwedzera, uchichinja, kana kudzima vlan tags kana kuchinja nzvimbo IP kero, traffic inotevedzwa kune yechipiri link. Semukati meInline nzira, NPB inogona kupawo kudzoreredzwa kune mamwe maturusi ematare, senge ids, Ips, kana firewalls. NPB inogona kutarisa mamiriro emidziyo yakadaro uye zvine simba re-nzira traffic kune inopisa kumira mune chiitiko chekutadza.
Iyo inopa kushanduka kukuru mumugwagwa wakasarudzika Iyo inopawo zvisingaenzaniswi network nekuona uye zvinovimbisa kuti midziyo yese inogamuchira kopi yemotokari yaida kubata nemazvo mabasa avo zvakanaka.
