Qee ISPs hauv lawv txoj kev siv zog los tawm tsam kev ua txhaum txoj cai zoo li cuam tshuam ftp thiab http qhov chaw pabcuam linux ntsig txog cov ntaub ntawv. Wireshark program muab pov thawj ntawm qhov no, ping thiab traceroute cov cuab yeej tuaj yeem pab txhawm rau txhawm rau txheeb xyuas cov nodes uas yog los ntawm ISPs hais tias ua rau txhaws qhov kev sib txuas tshwj xeeb thaum ib qho sim ua kom rub tawm raug cai. Cov txheej txheem pom zoo txhim kho lub sijhawm rub tawm. Raws li cov txiaj ntsig ib sab - ntau cov yeeb yaj kiab qeeb thiab zoo sib xws qhov ntim loj -seem kom tau txais txiaj ntsig los ntawm cov txheej txheem no.
Cov kauj ruam
Kauj Ruam 1. Koj yuav tsum kawm paub siv ob lub cuab yeej network:
ping thiab tracert (traceroute hauv linux). Thaum muaj qee qhov yooj yim nyem thiab nyem cov haujlwm siv cov cuab yeej no, txoj hauv kev yooj yim tshaj plaws yog siv kab hais kom ua, ob qho tib si hauv Windows thiab hauv Linux. Hauv linux koj yuav tsum qhib lub davhlau ya nyob twg (console) qhov rai.
Kauj Ruam 2. Hauv Windows, txhawm rau siv kab hais kom ua, koj yuav tsum mus rau Start - run (0r cmd)
Ua ntej sim ob peb qhov chaw, piv txwv li "ping google.com". Koj tuaj yeem siv www., Lossis tsis yog.
Kauj Ruam 3. Koj yuav tau txais qee cov ntaub ntawv ntawm cov khoom no:
"64 bytes ntawm maa03s17-in-f7.1e100.net (74.125.236.199): icmp_req = 1 ttl = 48 lub sij hawm = 329 ms"
Kauj Ruam 4. Tam sim no:
xyuam xim, - qhov no yog cov cuab yeej koj yuav siv rau koj kom zoo dua.
Kauj Ruam 5. Qhov cuab yeej thib ob xav tau yog "tracert" hauv Windows lossis "traceroute" hauv Linux
Ib zaug ntxiv qhib kab hais kom ua (Pib - khiav lossis cmd, lossis davhlau ya nyob twg hauv Linux) thiab ntaus: "tracert google.com" hauv Windows lossis "traceroute google.com" hauv Linux.
Kauj Ruam 6. Lub sijhawm no koj yuav tau txais xov xwm me ntsis ntxiv
Koj yuav pom cov chaw nyob ntawm cov nodes uas koj lub teeb liab tab tom taug kev, thiab TIMES nws siv ntawm txhua tus ntawm lawv.
Kauj Ruam 7. Xyaum me ntsis ntawm qee qhov chaw nyob dawb huv, ob qho tib si ping thiab traceroute
Kauj Ruam 8. Txoj haujlwm tshawb nrhiav
Kauj ruam 9. Coj qhov chaw nyob uas muab rau koj qee yam teeb meem ntsig txog koj rub tawm. Thawj "tracer (ou) t (e)" nws ntawm nws tus kheej. Cia peb hais "tracert ftp://myftpthingy.net". Nco tseg (lossis khaws cia rau cov ntawv sau) koj cov txiaj ntsig. Koj yuav tuaj yeem pom txog 10-30 nodes uas koj qhov kev sib txuas mus los. Lub sijhawm siv ntawm ib qho ntawm lawv yuav tsawg dua li ib pliag (1 millisecond yog 1 txhiab thib ob). Feem ntau los ntawm kwv yees li 30ms txog li 200ms. Muaj qee tus lej sib txawv ntawm no, tsis txhob txhawj ntau.
Kauj ruam 10. Tam sim no, pib koj rub tawm (lossis pib saib cov vis dis aus thiab zoo li no)
YUAV UA LI CAS THIAJ - "tracer (ou) t (e)" qhov chaw nyob dua. Yog tias koj tab tom ntsib teeb meem lossis teeb meem kev sib txuas - koj yuav pom qee qhov sib txawv ntawm cov milliseconds rau tib lub nodes. Qee tus lej no yuav khiav mus rau ob peb feeb. Qee lub hauv paus yuav ua txuj ua neeg ruam thiab nug ntxiv tias "kuv tus hlub yog dab tsi?", -Yog koj yuav pom ob peb ***. ** ms qhov tseem ceeb ntawm lawv. Heev feem ntau tom qab cov nodes no - kev sib txuas tau tawg.
Kauj Ruam 11. Nco tseg qhov chaw nyob ntawm cov kev ua txhaum no, piv txwv li:
0.ge-1-3-
- tag nrho txhua yam, qhov no tseem ceeb.
Netflix hla
Kauj Ruam 1. Cov theem kho
Kauj Ruam 2. Qee zaum koj tuaj yeem pib ua qhov no THAUM qhov rub tawm tau tshwm sim
Ntau zaus dhau los tsis yog, koj yuav tau rov pib dua qhov kev sib txuas, - kaw qhov browser, qhib dua.
Kauj Ruam 3. Qhib cov cuab yeej kab hais kom ua, thiab siv lo lus "ping"
Raws li qhov chaw nyob siv qhov chaw nyob ntawm lub node uas tau thov lub sijhawm ntau ntxiv, lossis khaws cia rau kev thov rov pib dua. Piv txwv li: "ping P15-3. CLPPVA-LCR-02.verizon-gni.net".
