Povijest ATM-a ATM – Asynchronous Transfer Mode Prvi radovi 1983. g. 1988. objedinjuju se koncepti ATDM-a i FPS-a Uloga: B-ISDN

Osnovna obilježja ATM-a CO – connection oriented Statističko multipleksiranje

Korisničko polje (48 okteta) ATM ćelija Veličina 53 okteta Nedodijeljena ćelija 4 okteta zaglavlja HEC Korisničko polje (48 okteta) zaglavlje (5 okteta) ćelija iz izvora 1 ćelija iz izvora 2 ćelija iz izvora 3 nedodijeljena ili prazna ćelija

Protokolna arihtektura B-ISDN PRM Korisnička (user plane) Kontrolna (control plane) Upravljačka (management plane) Svaka ravnina: Fizički sloj ATM sloj ATM prilagodni sloj PHY ATM AAL viši slojevi kontrolna ravnina korisnička ravnina upravljačka ravnina

Vrste ATM ćelija Fizički sloj: ATM sloj: Prazne (idle cell) Ispravne (valid cell) Neispravne (invalid cell) ATM sloj: Dodijeljene (assigned cell) Nedodijeljene (unassigned cell)

Upravljanje prometom u ATM mrežama CILJEVI: Maksimizirati učinkovitost Minimizirati kašnjenje i gubitke Prometni ugovor – dogovor između korisnika i mreže QoS – Quality of Service – kvaliteta usluge koju garantira mreža

Kašnjenje u ATM mrežama Dvije vrste mreža: ATM s kraja na kraj Mješovita (ATM i non-ATM) Parametri kašnjenja: TD - Transmissin Delay) PD - Packetization Delay) SD - Switching Del ay – FD (Fixed Delay) – QD (Queuing Delay) Kolebanje kašnjenja

Signalizacija u ATM mrežama Signalizacija odvojena od korisničke informacije Virtualni kanal

Signalizacija na sučelju ATM UNI UNI – za signalizaciju između mreže i korisnika obrada poziva DTE ATM komutator UNI korisnički VC signalizacijski VC VPI:0/VCI:5

Vrste veza u ATM mrežama Tri osnovne vrste veza: Trajne (permanent connection) Polutrajne (semi-premanent connection) Na zahtjev (on-demand connection)
