Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Zvichitevera kugadzirwa kwokutanga kweATM, network dzave dzichikurumidza zvikuru. 1500 byte (12000-bit) yakazara-saizi Ethernet furemu inotora chete 1.2 μs kuendesa pane 10 Gbit / s network, ichideredza kudiwa kwemasero madiki kudzikisira jitter nekuda kwekukakavara. Vamwe vanorangarira kuti ikoku kunopa chikonzero chokutsiva ATM neEthernet mumutsetse womusimboti. Kukurumidza kwokubatanidza kunowedzera pachako hakuderedzi jitter inokonzerwa nekumirira. Mukuwedzera, hardware yekushandisa shanduko yebasa yeIP packets inodhura pamwero mukuru kwazvo. Kunyanya, pakumhanya kweOC-3 nepamusoro, mutengo wekuparadzanisa uye kuunganidzazve (SAR) Hardware inoita kuti ATM isakwikwidzane neIP pane Packet Over SONET (POS); nekuda kweiyo yakatarwa 48-byte cell payload, ATM haina kukodzera sedata link layer yakanangana neIP (pasina kudiwa kweSAR padanho redata link) sezvo OSI layer iyo IP inoshanda inofanirwa kupa yakanyanya kutumira unit (MTU) yeinosvika 576 bytes. SAR performance limits inoreva kuti IP router ATM interfaces dzinokurumidza ndeye STM16 - STM64 iyo inonyatsoenzanisa, nepo kubva muna 2004 POS inogona kushanda paOC-192 (STM64) nekumhanya kwakakwirira kunotarisirwa mune ramangwana, miganho yakavakirwa pakuparadzanisa nekubatanidzazve (SAR).  Mubvunzo: Chii chiri chinotsiva chakarongwa nokuda kweATM?
