Presentation Transcript

  1. User, Control, and Management Planes • User Plane • SCSS (Service Specific Convergence Sublayer) Protocols • Frame relay SCSS • SMDS SCSS • Null SCSS for IP or circuit emulation • Higher Layers • IETF RFC 1483: Multiprotocol Encapsulation Over ATM • IETF RFC 1577: Classical IP Over ATM • Control Plane • Support • Switched Virtual Connections (SVC) • Permanent Virtual Connections (PVC) • Management Plane • Layer Management • Plane Management BISDN/黃仁竑副教授

  2. Control Plane Architecture B-ISUP DSS2 (Q.2931) MTP3 SSCF-UNI (Q.2130) SSCF-UNI (Q.2130) SAAL (reliable transport) SCCOP (Q.2110) SCCOP (Q.2110) AAL AAL Access Node ATM ATM User Node Tandem Node PHY PHY * SCCOP: retransmission based on selective repeat * SSCF: Service Specific Coordination Function BISDN/黃仁竑副教授

  3. B-ISUP B-ISUP Q.2931 Q.2931 Q.2931 Q.2931 SAAL SAAL SAAL SAAL ATM ATM ATM ATM PHY PHY PHY PHY Control Plane UNI NNI UNI Q.2931 Q.2931 SAAL SAAL ATM ATM PHY PHY B-ISUP: Broadband ISDN User Part BISDN/黃仁竑副教授

  4. Control Plane Addressing and Routing • A point-to-point SVC consist of • forward /backward VPI/VCI • ATM UNI port addresses of the source and destination nodes • A point-to-multipoint SVC consist of • VPI/VCI, ATM address of the root • VPI/VCI, ATM addresses of the leaf nodes BISDN/黃仁竑副教授

  5. Multicasting Issues • Point-to-multipoint • AAL5 point-to-multipoint connection must be unidirectional to prevent cell interleaving • Multipoint-to-multipoint • VP-multicasting: construct a multipoint-to-multipoint VP? • Multicast Server • Overlaid point-to-multipoint BISDN/黃仁竑副教授

  6. SVC Addressing • Two types of addressing plans are considered • NSAP (Network Service Access Point): • DCC: ISO 3166 • ICD : British Standards Institute • E.164 (ITU-T) • ISDN and telephone numbers • Each address format consists of (IDP+DSP) • IDP: includes AFI and IDI • AFI (Authority and Format Identifier) • 1-octet, identifies the DSP format, DCC(39), ICD(47), E.164(45) • IDI (Initial Domain Identifier): address domain and network addressing authority • DSP (Domain Specific Part): the address determined by the network authority BISDN/黃仁竑副教授

  7. Q.2931 Call Setup Procedure BISDN/黃仁竑副教授

  8. Addressing Model • Peer model • Needs ATM ARP (IP -> ATM) • Overlay model • Complicate ATM switch (multiprotocol routers) BISDN/黃仁竑副教授

  9. Management Plan • Layer Management • With management interface to each layer (PHY, ATM, AAL, higher layers) in both control and user planes • Monitoring user and control plane for faults • generating alarms • taking corrective actions • monitoring compliance to the performance stated in the traffic contract • Plane Management • has no defined structure yet BISDN/黃仁竑副教授
