Distance vector routing yog asynchronous algorithm nyob rau hauv uas node x xa cov ntawv luam ntawm nws nrug vector rau tag nrho nws cov neeg zej zog. Thaum node x tau txais qhov tshiab nrug vector los ntawm ib qho ntawm nws cov neeg nyob sib ze vector ,v, nws saves nrug vector ntawm v thiab siv Bellman-Ford kab zauv los hloov kho nws tus kheej nrug vector.
Ib yam li ntawd, nws yog nug, qhov nrug vector routing raws tu qauv muab 2 piv txwv yog dab tsi?
Muaj ob peb routing raws tu qauv uas siv nrug vector algorithms, tshwj xeeb tshaj yog kev txiav txim routing raws tu qauv . Qee qhov ntau dua piv txwv uas tseem siv niaj hnub no yog RIPv1, RIPv2, thiab Sab Hauv Gateway Routing raws tu qauv (IGRP).
Ib tug kuj yuav nug, dab tsi yog txhais los ntawm routing algorithm? A routing algorithm yog ib txheej txheej ntawm kev ua haujlwm ib kauj ruam uas siv los tswj kev khiav hauv Internet kom zoo. Thaum ib pob ntawv ntawm cov ntaub ntawv tawm ntawm nws qhov chaw, muaj ntau txoj hauv kev uas nws tuaj yeem coj mus rau nws qhov chaw. Cov routing algorithm yog siv los txiav txim lej txoj hauv kev zoo tshaj plaws.
Qhov thib ob, dab tsi yog qhov kev txwv ntawm kev nrug vector routing?
Disadvantages ntawm Distance Vector routing -
- Nws yog qeeb dua rau converge tshaj qhov txuas xeev.
- Nws yog qhov txaus ntshai los ntawm qhov teeb meem suav-rau-infinity.
- Nws tsim kev khiav tsheb ntau dua li lub xeev txuas txij li kev hloov pauv suav yuav tsum tau nthuav tawm rau txhua lub routers thiab ua tiav ntawm txhua lub router.
Dab tsi routing raws tu qauv yog qhov nrov tshaj plaws nyob deb vector routing algorithm?
RIP
Pom zoo:
Dab tsi yog sparse kem Dab tsi yog qhov zoo thiab qhov tsis zoo?
Koj poob 4 bytes tsis yog ib zaug ib kab; tab sis rau txhua lub cell hauv kab uas tsis yog null. Qhov zoo ntawm SPARSE kem yog: Qhov tsis zoo ntawm SPARSE kem yog: SPARSE kem tsis tuaj yeem siv rau ntawm cov ntawv, ntext, duab, timestamp, geometry, geography lossis cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog qhov txawv ntawm qhov encryption algorithm thiab tus yuam sij?
Algorithm yog pej xeem, paub los ntawm tus neeg xa khoom, tus txais, tus neeg tawm tsam thiab txhua tus neeg paub txog kev encryption. Qhov tseem ceeb ntawm qhov tod tes yog tus nqi tshwj xeeb uas siv los ntawm koj nkaus xwb (thiab tus neeg txais thaum muaj Symmetric Encryption). Qhov tseem ceeb yog dab tsi ua rau koj cov lus encrypted tshwj xeeb ntawm cov uas siv los ntawm lwm tus
Puas yog Eigrp yog lub xeev txuas lossis qhov chaw nyob deb vector routing raws tu qauv?
EIGRP yog qhov kev ncua deb vector routingprotocol uas suav nrog cov yam ntxwv tsis pom nyob rau hauv lwm cov kev sib txuas lus sib txuas xws li RIP thiab IGRP. " EnhancedInterior Gateway Protocol yog dynamic hybrid/advanceddistance vector raws tu qauv uas siv ob qho tib si ntawm lub xeev txuas nrog rau qhov nrug vectorprotocol
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
