Nekuti maLAN switch anoshandisa virtual circuit switching, anogona kuve nechokwadi chekuti bandwidth pakati pema input ne output ports ese haina gakava, zvichiita kuti data ritumirwe nekukurumidza pakati pema ports pasina kukonzera matambudziko e transmission. Izvi zvinowedzera zvakanyanya data throughput yema network information points uye zvinogadzirisa network system yese. Chinyorwa chino chinotsanangura matekinoroji mashanu makuru anobatanidzwa.
1. ASIC (Dunhu Rakabatanidzwa Rinorongwa)
Iyi i-integrated circuit chip yakagadzirirwa kunyatsogadzirisa Layer-2 switching. Ndiyo tekinoroji huru yekubatanidza inoshandiswa mukugadzirisa networking nhasi. Mabasa akawanda anogona kubatanidzwa kune imwe chip, zvichipa zvakanakira zvakaita sekugadzira kuri nyore, kuvimbika kwakanyanya, kushandiswa kwesimba shoma, kushanda kwepamusoro, uye mutengo wakaderera. MaASIC chips anorongwa anoshandiswa zvakanyanya muLAN switches anogona kugadziriswa nevagadziri—kana kunyange nevashandisi—kuti aenderane nezvinodiwa zveapplication. Ave imwe yematekinoroji akakosha muLAN switch applications.
2. Mapaipi Akaparadzirwa
Nekugoverwa kwemapaipi, mainjini akawanda ekufambisa anogoverwa anogona kutumira mapaketi awo nekukurumidza uye ega. Mupaipi imwe chete, machipisi akawanda eASIC anogona kugadzirisa mafuremu akawanda panguva imwe chete. Kubatanidzwa uku uye kufambiswa kwemapaipi kunosimudzira mashandiro ekufambisa kusvika padanho idzva, zvichizadzisa kushanda kwemuganho wemagetsi eunicast, broadcast, uye multicast traffic pamaports ese. Nokudaro, kugoverwa kwemapaipi chinhu chakakosha mukuvandudza kumhanya kweLAN switching.
3. Memory Inokura Zvikuru
Kune zvigadzirwa zveLAN switching zvemhando yepamusoro, kushanda kwepamusoro uye mashandiro emhando yepamusoro zvinowanzo shandiswa pakushandisa system yekurangarira yakangwara. Tekinoroji yekurangarira inokura zvakanyanya inobvumira switch kuwedzera kugona kwekurangarira panguva imwe chete zvichienderana nezvinodiwa netraffic. MuLayer-3 switches, chikamu chememori chinobatanidzwa zvakananga neinjini yekutumira, zvichigonesa kuwedzerwa kwemamodules akawanda einterface. Sezvo huwandu hweinjini dzekutumira huchiwedzera, memori inobatanidzwa inowedzera zvinoenderana. Kuburikidza neASIC processing yakavakirwa papipeline, mabuffer anogona kuvakwa nenzira inochinja kuti awedzere kushandiswa kwememori uye kudzivirira kurasikirwa kwepaketi panguva yekuputika kukuru kwedata.
4. Maitiro Ekutsvaga Mutsetse Wepamusoro
Kunyangwe mudziyo wenetwork uine simba rakadii, ucharamba uchitambura nekuzara kwezvikamu zvenetwork zvakabatana. Kazhinji, traffic pachiteshi inochengetwa mumutsara mumwe chete wekubuda, inogadziriswa zvakanongedzwa neFIFO zvisinei nekuti chii chinonyanya kukosha. Kana mutsara wazara, mapaketi akawandisa anodonhedzwa; kana mutsara wakareba, kunonoka kunowedzera. Iyi nzira yetsika yekuisa mumutsara inokonzera matambudziko kumapurogiramu epanguva chaiyo uye emultimedia.
Saka, vatengesi vazhinji vakagadzira matekinoroji epamusoro ekuisa mutsetse kuti vatsigire masevhisi akasiyana-siyana pazvikamu zveEthernet, uku vachidzora kunonoka uye kushamisika. Izvi zvinogona kusanganisira mazinga akawanda emitsara pachiteshi chimwe nechimwe, zvichigonesa kusiyanisa zviri nani mazinga etraffic. Mapaketi emultimedia uye data real-time anoiswa mumitsara inonyanya kukosha, uye nematanho akayerwa, mitsara iyi inogadziriswa kakawanda—pasina kuregeredza zvachose traffic yakaderera. Vashandisi vemapurogiramu echinyakare havaoni shanduko munguva yekupindura kana throughput, nepo vashandisi vari kushandisa mapurogiramu akakosha panguva vachigamuchira mhinduro nenguva.
5. Kupatsanurwa Kwemotokari Otomatiki
Mukutapurirana kwenetiweki, mamwe mafambisirwo edata akakosha kupfuura mamwe. Maswichi eLayer-3 LAN atanga kushandisa tekinoroji yekupatsanura traffic otomatiki kuti asiyanise mhando dzakasiyana dzetraffic nezvinokosheswa. Maitiro ekudzidzira anoratidza kuti nekupatsanura otomatiki, maswichi anogona kuraira pombi yekugadzirisa mapaketi kuti isiyanise mafambisirwo akasarudzwa nemushandisi, zvichiita kuti pave nekunonoka kwakaderera uye kutumira zvinhu zvakanyanya kukosha. Izvi hazvingopi chete kutonga kwakanaka uye manejimendi ekufambisa traffic, asiwo zvinobatsira kudzivirira kuzara kwenetwork.
