Ntchito ndi chizindikiro cholunjika kwambiri

Kwa masinthidwe amtundu wofikira, zitsimikizo zosavuta za QoS, njira zotetezera, kuthandizira njira zoyendetsera maukonde, ma protocol amitengo ndi ma VLAN onse ndi ntchito zofunika, komabe, ngati musanthula mosamala, ntchito zina zitha kugawikanso pansi pakuwoneka kosavuta, ndipo izi zimagawika. ntchito ndiye chifukwa chachikulu cha kusiyana kwazinthu komanso njira yofunikira yowonetsera mtengo wowonjezera wazinthu. Kuti apatse ogwiritsa ntchito kusinthasintha kwakukulu pakugwiritsa ntchito, mfundo ya QoS yosinthira iyenera kuthandizira zoikamo zoyambira pamapaketi angapo, choyambirira chikhoza kukhazikitsidwa pa adilesi ya MAC, VLAN, adilesi ya IP, ndi doko motsatana. Nthawi yomweyo, kusinthaku kumayenera kukhala ndi mphamvu zowongolera kusokonekera komanso kuthekera koletsa kuyenda, kuthandizira mautumiki osiyanitsidwa ndi Diffserv, ndikusiyanitsa mwanzeru mitsinje yosiyanasiyana yogwiritsira ntchito potengera gwero/kopita MAC/IP kuti ikwaniritse zosowa za nthawi yeniyeni yogwiritsa ntchito ma multimedia. Ngakhale masinthidwe ena pamsika pano amati ali ndi zitsimikizo za QoS, amangothandizira zoikamo zoyambira pamlingo umodzi, zomwe zimabweretsa zovuta zambiri pazogwiritsa ntchito ogwiritsa ntchito.

Thandizo la VLAN

VLAN ndi netiweki yam'deralo. Mwa kugawa maukonde am'deralo kukhala magawo pafupifupi maukonde a VLAN, kasamalidwe ka maukonde ndi chitetezo cha maukonde zitha kulimbikitsidwa, ndipo kuwulutsa kwa data kosafunikira kumatha kuwongoleredwa, Gulu logwira ntchito pamanetilo limatha kudutsa malire omwe amagawana nawo, ndikugawanitsa subnet malinga ndi ntchito yoyang'anira, masiwichi a opanga osiyanasiyana ali ndi kuthekera kosiyanasiyana kwa ma VLAN, komanso kuchuluka kwa ma VLAN omwe amathandizidwa nawonso ndi osiyana. Ntchito yoyang'anira maukonde Kupyolera mu ntchito yoyang'anira maukonde, mungagwiritse ntchito mapulogalamu oyang'anira kuti muyang'anire ndikusintha kusintha, mwachitsanzo, kungathe kuyendetsedwa kudzera pa Webusaiti, Telnet, SNMP, RMON, etc. Kawirikawiri, osintha opanga amapereka mapulogalamu oyang'anira kapena chachitatu. -mapulogalamu owongolera chipani kuti azitha kuyang'anira kusintha kwakutali. Kusintha kwachindunji kumakumana ndi SNMPMIBI / MIBII ntchito zowerengera zowerengera, ndikuthandizira kasinthidwe kasamalidwe, kasamalidwe kaubwino wautumiki, kasamalidwe ka ma alarm ndi njira zina, kusintha kwa Gigabit kovutirapo kumathandizira kuwunika kogwira ntchito kwa RMON powonjezera gulu la RMON lomangidwa (mini-RMON).

Link aggregation

Kuphatikizika kwa ulalo kungapangitse bandwidth yolumikizana pakati pa masinthidwe ndi pakati pa masinthidwe ndi ma seva kukhala ndi scalability yabwino, mwachitsanzo, maulalo awiri, atatu, ndi anayi a gigabit amatha kulumikizidwa palimodzi kuwirikiza kawiri bandwidth. Khazikitsani maulalo osafunikira pamanetiweki, ndikugwiritsa ntchito Spanning Tree Protocol kuti mutseke ulalo wosunga zobwezeretsera, womwe mwanzeru supanga lupu. Kukanika kuchitika, ulalo wosunga zobwezeretsera umayatsidwa.

Thandizani protocol ya VRRP

VRRP (Virtual Routing Redundancy Protocol) ndi njira yothetsera kudalirika kwa maukonde. Mu protocol iyi, chipata chosasinthika (DefaultGateway) cha chipangizo cha terminal cha IP pamayendedwe ofikira angapo omwe amagawana nawo ambiri amathandizidwa mochulukirapo, kotero kuti chimodzi mwazinthu zosanjikiza zitatu chikatsika, chipangizo chosungirako chidzatenga kutumiza. ntchito mu nthawi, Wosuta amapereka mandala handover, amene bwino ntchito maukonde. Protocol ya VRRP ndi yofanana ndi protocol ya Cisco's HSRP, koma HSRP ndi eni ake a Cisco. Pakalipano, opanga masinthidwe akuluakulu athandizira kale VRRP protocol muzinthu zawo, koma zidzatenga nthawi kuti zigwiritsidwe ntchito kwambiri.
