Sei Nzvimbo Yenyu Yekuchengetedza Data Ichida Vatengesi Vemapaketi Emagetsi?
Chii chinonzi network packet broker?
Network packet broker (NPB) tekinoroji inoshandisa maturusi akasiyana-siyana ekutarisa kuti iwane uye iongorore traffic mu network. Ma "packet broker" anosefa ruzivo rwetraffic kubva kuma "network links" uye anoaparadzira kune chishandiso chayo chekutarisa network. Nekuva nehunyanzvi hwe "advanced filtering", NPB inogona kubatsira kupa data performance iri nani, kuchengetedzeka kwakasimba, uye nzira inokurumidza yekuona chikonzero chezvinetso zvese nekushandisa advanced application intelligence. NPB inowedzera kushanda zvakanaka kwenetwork uku ichidzikisa mari yako panguva imwe chete. Network packet brokers dzimwe nguva dzinogona kunzi "data access switches", "monitoring switches", "matrix switches", kana "tool aggregators".
Munyika yanhasi ine hunyanzvi hwedhijitari, nzvimbo dzedata dzinoita basa rakakosha mukutarisira nekuchengetedza ruzivo rwakawanda. Nekuwedzera kuri kudiwa kwekushanda kwenetwork kwakavimbika uye kwakanaka, zvakakosha kuti nzvimbo dzedata dzive ne network packet brokers (NPBs). Kunyangwe kana nzvimbo yedata isati yaisa 100G ethernet, NPB inogona kubatsira zvikuru.
Mukati medata centre, maturusi akasiyana-siyana anoshandiswa kutarisa mashandiro enetwork, kupa pachena, uye kuderedza njodzi nemabasa akaipa. Maturusi aya anovimba zvakanyanya nerukova rwemapaketi kuti ashande zvinobudirira. Zvisinei, pasina NPB, kutarisira nekuparadzira mapaketi aya kunogona kuva basa rakaoma.
NPB inoshanda senzvimbo huru inounganidza, inoronga, uye inopa network traffic kune maturusi ekutarisa kana ekuchengetedza anodiwa. Inoshanda semupurisa wetraffic, ichiona kuti mapaketi akakodzera anosvika kumaturusi akakodzera, ichivandudza mashandiro awo uye ichibvumira kuongororwa kuri nani nekugadzirisa matambudziko.
Chimwe chezvikonzero zvikuru nei nzvimbo yedata ichida NPB kugona kwayo kugadzirisa kumhanya kwenetwork kuri kuwedzera. Sezvo tekinoroji ichifambira mberi, kumhanya kwenetwork kuri kuramba kuchiwedzera. Zvishandiso zvekutarisa network zvechinyakare zvinogona kunge zvisina kugadzirirwa kubata huwandu hwemapaketi akagadzirwa nemanetwork ane kumhanya kwakanyanya akadai se100G ethernet. NPB inoshanda semutongi wetraffic, ichideredza kumhanya kwenetwork kusvika pakumhanya kunogoneka kwezvishandiso, ichiona kuti kutarisa uye kuongorora kwakarurama.
Uyezve, NPB inopa mukana wekukwanisa kukura uye kuchinjika kuti ikwane zvinodiwa zviri kuramba zvichikura zvedata center. Sezvo traffic yenetwork ichiwedzera, zvimwe zvishandiso zvingada kuwedzerwa kuzvivakwa zvekutarisa. NPB inobvumira kubatanidzwa kwezvishandiso zvitsva nyore nyore pasina kukanganisa magadzirirwo enetwork aripo. Inoita kuti zvese zvishandiso zvekutarisa nekuchengetedza zvikwanise kuwana mapaketi anodiwa, zvisinei nehukuru uye kuoma kwenetwork.
Nzvimbo dzedata dzinosanganawo nedambudziko rekutarisira traffic kubva kunzvimbo dzakasiyana mukati me network. Nekuwanda kwezvivakwa zvakapararira, zvakakosha kuve nekuonekwa kwakabatana uye kutonga traffic ye network. NPB inoshanda senzvimbo yepakati yekuunganidza traffic yese ye network, ichipa ongororo yakazara ye network yese. Kuonekwa uku kwakabatana kunobvumira kutarisa zviri nani, kugadzirisa matambudziko, uye kuongorora kuchengetedzeka.
Pamusoro pezvo, NPB inovandudza kuchengetedzeka mukati menzvimbo yedata nekupa kugona kwekupatsanura network. Nekutyisidzirwa kunogara kuripo kwekurwiswa kwecyber nevanhu vane hutsinye, zvakakosha kuparadzanisa nekutarisa traffic yenetwork kuti vaone uye vaderedze chero njodzi dzinogona kuitika. NPB inogona kusefa nekucheka traffic yenetwork zvichienderana nezvinodiwa zvakasiyana-siyana, zvakaita se IP address kana protocol type, zvichiita kuti traffic inofungirwa itumirwe kuti iongororwe zvakanyanya uye kudzivirira chero kutyorwa kwekuchengetedzwa kunogona kuitika.
Uyezve, NPB inoitawo basa rakakosha mukuonekwa kwenetwork uye kutarisa mashandiro ayo. Inopa ruzivo rwakadzama nezve traffic yenetwork, zvichibvumira vatariri vedata center kuona zvipingamupinyi, matambudziko ekunonoka, kana chero zvimwe zvinetso zvekushanda kwayo. Nekuva nemufananidzo wakajeka wekushanda kwenetwork, vatariri vanogona kuita sarudzo dzakangwara dzekuvandudza network uye kuvandudza mashandiro ayo ese.
Pamusoro pemabhenefiti aya, NPB inoitawo kuti network monitoring infrastructure ive nyore nekuderedza huwandu hwezvishandiso zvekutarisa zvinodiwa. Panzvimbo pekushandisa maturusi akawanda akazvimirira pabasa rega rega rekutarisa, NPB inosanganisa mashandiro acho kuita puratifomu imwe chete. Kubatanidzwa uku hakungochengetedzi nzvimbo chete asiwo kunoderedza mari inobatanidzwa nekutenga, kutarisira, uye kuchengetedza maturusi akawanda.
Uyezve, NPB inovandudza kushanda zvakanaka kwekutarisa nekugadzirisa matambudziko. Nekukwanisa kusefa nekuendesa mapaketi chaiwo kune zvishandiso zvinodiwa, vatariri venzvimbo dzedata vanogona kuona nekugadzirisa matambudziko enetwork nekukurumidza. Nzira iyi inorerutsa kuchengetedza nguva nezviwanikwa, ichiva nechokwadi chekuti nguva yekushanda yakaderera uye inowedzera kuwanikwa kwenetwork.
Mukupedzisa, NPB chinhu chakakosha chezvivakwa zvedata center. Inopa kugona kwakakosha kwekutarisira, kugovera, uye kugadzirisa traffic yenetwork, ichivimbisa kutarisa, kuchengetedzeka, uye kuongorora mashandiro zvakanaka. Nekuwedzera kwezvinodiwa zvenetwork dzinomhanya zvakanyanya uye magadzirirwo akapararira, NPB inopa kugona kukura, kuchinjika, uye centralization inodiwa kuti igadzirise matambudziko aya zvakananga. Nekudyara mari muNPB, vashandi vedata center vanogona kuve nechokwadi chekushanda zvakanaka uye kusimba kwezvivakwa zvavo zvenetwork uku vachideredza njodzi dzinogona kuitika uye kuchengetedza data rinokosha.
