Vatengi vanotida sei kuti tiongorore mashandiro etiweki, uye isu tinokwanisa kuiongorora kubva pazvinhu zvina izvi.
1. Bandwidth :
Bandwidth inotsanangurwa muBaidu Encyclopedia: iyo "yepamusoro data mwero" inogona kupfuura kubva pane imwe nzvimbo mumambure kuenda kune imwe nzvimbo pachikamu chenguva.
Iyo bandwidth yetiweki yekombuta ndiyo yakanyanya dhata data iyo network inogona kupfuura nayo, kureva mabheti mangani pasekondi (iyo yakajairika unit bps (bit pasekondi)).
Zvichitaurwa zviri nyore: bandwidth inogona kufananidzwa nemugwagwa mukuru, zvichiratidza nhamba yemotokari dzinogona kupfuura pachikamu chenguva;
2. Bandwidth inomiririra:
Bandwidth inowanzoratidzwa sebps, zvichiratidza kuti yakawanda sei pasekondi;
"Bits pasekondi" inowanzosiyiwa kana ichitsanangura bandwidth. Semuenzaniso, bandwidth i100M, inova 100Mbps, apo Mbps inoreva megabits/s.
Asi iyo unit yekumhanyisa yatinowanzo kurodha software ndeye Byte/s (byte/second). Izvi zvinosanganisira kushandurwa kweByte uye bit. Imwe neimwe 0 kana 1 mubhinari nhamba system idiki, uye diki ndiyo diki diki yekuchengetera data, iyo 8 bits inonzi byte.
Naizvozvo, kana isu tichibata Broadband, 100M bandwidth inomiririra 100Mbps, iyo theoretical network yekurodha kumhanya ingori 12.5M Bps, inogona kunge iri pasi pe10MBps, izvi imhaka yekushandiswa kwekombuta yemushandisi, mhando yemidziyo yetiweki, kushandiswa kwezviwanikwa, network peak, network. sevhisi huwandu, kuparara kwemutsara, chiratidzo chekudzivirira, iyo chaiyo network yekumhanyisa haikwanise kusvika pakumhanya kwedzidziso.
2.Kunonoka kwenguva:
Zvichitaurwa zviri nyore, kunonoka kunoreva nguva inodiwa kuti meseji iende kubva kumagumo etiweki kuenda kune imwe;
Kubva pamigumisiro yeping, unogona kuona kuti nguva inononoka ndeye 12ms, iyo inoreva ICMP meseji kubva pakombuta yangu kuenda kuBaidu's server inodiwa nguva-yerwendo nguva kunonoka ndeye 12ms;
(Ping inoreva nguva yekumashure nekumashure apo packet inotumirwa kubva kumudziyo wemushandisi kuenda kunzvimbo yekuyeresa kumhanya, yobva yangodzoserwa kumudziyo wemushandisi. Kureva, kunowanzozivikanwa sekunonoka kwenetiweki, inoverengerwa mumillisecond ms.)
Kunonoka kwenetiweki kunosanganisira zvikamu zvina: kunonoka kugadzirisa, kunonoka kwemutsetse, kunonoka kutapurirana uye kunonoka kuparadzira. Mukuita, isu tinonyanya kufunga nezve kunonoka kutapurirana uye kunonoka kutapurirana.
3.Kuzunungusa
: network jitter inoreva musiyano wenguva pakati pekunonoka kwakanyanya uye kunonoka kudiki. Semuenzaniso, kunonoka kwakanyanya paunoshanyira webhusaiti ndeye 10ms, uye kunonoka kunonoka ndeye 5ms, ipapo network jitter ndeye 5ms; jitter = kunonoka kwakanyanya-kunonoka kunonoka, kuzunungusa = kunonoka kwakanyanya-kunonoka kunonoka
kuzunungusa kunogona kushandiswa kuongorora kugadzikana kwetiweki, iyo diki jitter, iyo yakanyanya kugadzikana network;
Kunyanya kana tichitamba mitambo, tinoda kuti network ive nekugadzikana kwepamusoro, zvikasadaro zvinokanganisa chiitiko chemutambo.
Nezve chikonzero che network jitter: kana network congestion ikaitika, kunonoka kwemutsetse kuchakanganisa kunonoka-kusvika-kumagumo kunonoka, izvo zvinogona kukonzera kunonoka kamwe kamwe kukuru uye kudiki kubva kune router A kuenda kune router B, zvichikonzera network jitter;
4.Packet kurasikirwa
: Zvichitaurwa, kurasikirwa kwepaketi kunoreva kuti iyo data yeimwe kana akawanda data packet haigone kusvika kwainoenda kuburikidza netiweki. Kana iye anogamuchira akaona kuti data rakarasika, rinotumira chikumbiro kune anotumira zvinoenderana nemutsara serial nhamba yekuitisa kurasikirwa kwepaketi uye kutumirazve.
Pane zvikonzero zvakawanda zvekurasa mapaketi, izvo zvinonyanya kuzivikanwa zvinogona kunge zviri network congestion, data traffic yakakura kwazvo, network michina haigone kubata zvakangoitika mamwe mapaketi edata anorasika.
Chiyero chekurasikirwa kwepakiti ndiyo chiyero chenhamba yemapakiti akarasika mukuedzwa kune mapaketi akatumirwa. Semuenzaniso, kana iwe ukatumira 100 mapaketi uye ukarasa imwe packet, iyo packet kurasikirwa mwero ndeye 1%.
