Changfei Kirasi: Chii chinonzi Core Switch? Ndeupi musiyano kubva kune yenguva dzose switch

Kutanga, ngatitarisei pane:

Core switches haisi mhando yekuchinja,
Iyo switch inoiswa pa core layer (network backbone).
1. Chii chinonzi core switch

Kazhinji, mabhizinesi makuru network uye internet cafes inoda kutenga epakati switch kuti iwane yakasimba network yekuwedzera hunyanzvi uye kuchengetedza mari iripo. Chete kana huwandu hwemakomputa hwasvika pane imwe nhanho hunogona kushandiswa core switch, nepo pasina kudiwa kwepakati switch pazasi makumi mashanu, uye nzira yakakwana. Iyo inonzi core switch inoreva network architecture. Kana iri diki nharaunda network ine akati wandei makomputa, 8-chiteshi diki switch inogona kunzi core switch. Core switch kazhinji inoreva Layer 2 kana Layer 3 switch ine ese ari maviri network manejimendi mabasa uye yakasimba throughput. Munzvimbo yetiweki ine anopfuura 100 makomputa, yakakosha switch yakakosha kune yakagadzikana uye yakakwirira-kumhanya kushanda.

2. Kusiyana pakati pema core switch uye nguva dzose

maswichi: Huwandu hwezviteshi mukuchinja nguva dzose kazhinji 24-48, uye ruzhinji rwenetiweki ports igigabit Ethernet kana gigabit Ethernet ports. Basa guru nderekuwana data remushandisi kana kuunganidza chinja data kubva kune mamwe maseru ekuwana. Rudzi urwu rwekuchinja runogona kugadziridzwa neVlan yakapusa routing protocol uye mamwe ari nyore SNMP mabasa zvakanyanya, uye iyo backplane bandwidth idiki. Kune nhamba huru ye core switch ports, iyo inowanzoita modular uye inogona kubatanidzwa zvakasununguka ne optical ports uye gigabit Ethernet ports. Kazhinji, machinjiro epakati ndiwo matatu-layer switch anogona kuseta akasiyana epamberi network maprotocol senge nzira maprotocol/ACL/QoS/load balancing. Chinonyanya kukosha ndechekuti iyo backplane bandwidth yecore switch yakakwira zvakanyanya kupfuura iyo yenguva dzose switch, uye ivo vanowanzove neakaparadzana enjini module uye ari ekutanga uye backup. Musiyano uripo pakati pevashandisi vanobatana kana kuwana network: Chikamu chetiweki chinotarisana zvakananga nevashandisi vanobatana kana kuwana network inowanzo kunzi iyo yekupinda layer, uye chikamu chiri pakati peiyo yekupinda layer uye yepakati layer inodaidzwa sekugovera. layer kana aggregation layer. Chinangwa chechikamu chekuwana ndechekubvumira vashandisi vekupedzisira kuti vabatanidze kunetiweki, saka iyo yekupinda layer switch ine hunhu hwemutengo wakaderera uye yakakwira port density. Iyo convergence layer switch inzvimbo yekuchinjisa yeakawanda yekupinda layer switch, iyo inofanirwa kukwanisa kubata ese traffic kubva kune yekuwana layer zvishandiso uye nekupa uplink kune yakakosha layer. Naizvozvo, aggregation layer switch ine mashandiro epamusoro, mashoma machinjiro, uye yakakwirira yekuchinjisa mitengo. Iyo musana wetiweki unonzi core layer, ine chinangwa chikuru chekupa yakagadziridzwa uye yakavimbika musana wekutapurirana chimiro kuburikidza nepamusoro-kumhanya kutumira kutaurirana. Naizvozvo, iyo core layer switch application ine yakakwirira kuvimbika, kuita, uye kubuda.
Kuenzaniswa neyakajairwa switch core switch, ivo vanofanirwa kuve nemaficha akadai sehombe cache, yakakwirira huwandu, virtualization, scalability, uye module redundancy tekinoroji. Parizvino, musika wekuchinja wakasanganiswa, uye mhando yechigadzirwa haina kuenzana. Vashandisi vanogona kuterera kuCF FIBERLINK mukusarudza kwechigadzirwa, uye zvechokwadi pane imwe yakakodzera yepakati switch yako!
