ATM and MPLS Training
Who Should Attend?
The course is intended for transport network and datacom network engineers who needs technical knowledge on functionality of ATM and MPLS. The course also will be beneficial for GSM/UMTS Core Network engineers deploying ATM as the transport layer solution for 2G and 3G networks.
Course Content
Part 1 - ATM
- Introduction: standardisation, ATM Cell, PVC/SVC connections, switching and multiplexing, protocol layers.
- Physical Layer: physical interfaces supported, cell delineation process.
- ATM Layer: cell header, flow and congestion control, virtual paths and channels.
- ATM Adaptation Layer: QoS categories, traffic classes, AAL 1, AAL 2, AAL 3/4, AAL 5 and SAAL.
- Signalling: addressing, UNI signalling (Q.2931), NNI Signalling (PNNI, B-ICI, AINI, IISP).
- Network Management: SNMP, ILMI.
- ATM Traffic Descriptors and QoS Parameters: traffic management, traffic descriptors (PCR, SCR, MBS, MCR, CDVT), QoS parameters (CLR, max-CTD, P2P-CDV, CER, SECBR, CMR).
- Traffic Control: Connection Admission Control (CAC), virtual bandwidth, traffic shaping and policing, Generic Cell Rate Algorithm (GCRA).
- ATM Applications: Voice over ATM (with ALL1 and ALL2), IP over ATM (CLIP, MARS, LANE, MPOA, MPLS), ATM in 3G fixed and mobile networks.
Part 2 - MPLS
- MPLS Overview: standard bodies, conventional routing model, MPLS forwarding model, address and label concept, additional benefits, traffic engineering, QoS routing, multiprotocol support.
- Components of MPLS networks: terminology (FEC Forward Equivalent Class, Label, MPLS header), Label Stack Router LSR, Next hop label forwarding entry NHLFE, Incoming label map ILM, FEC-to-NHLFE map FTN.
- Label swapping: forwarding a labeled packet, forwarding an unlabeled packet, penultimate hop popping, label switched path (LSP), label stack and label hierarchies, stream merge.
- Signalling and routing protocols: label distribution methods, extensions to existing protocols and new protocols, LDP, OSPF, BGP and RSVP in MPLS Networks.
- MPLS, ATM and Frame Relay: cell-switched MPLS terminology, unique features of ATM LSRs, cell-switched MPLS label space, encapsulation, MPLS and Frame Relay.
- Traffic Engineering: constraint-based routing with CR-LDP, explicit routes, route pinning, resource classes, traffic parameter specification, path pre-emption, CR messages.
- MPLS and QoS: MPLS and DiffServ, MPLS and IntServ/RSVP.
- MPLS and VPN.
Course Objectives
ATM & MPLS course takes a close look at the purpose and principle of the Asynchronous Transfer Mode (ATM) and Multiprotocol Label Switching (MPLS). The first part of the course is focused on ATM, covering topics from cell format over circuits and connections to ATM network traffic and internetworking. It contrasts alternative technologies including IP and Frame Relay and discusses multi-service traffic types and quality of service (QoS). The second part of the course is focused on switching of IP traffic though a ATM network with use of Multi Protocol Label Switching (MPLS) including the routing and QoS aspects of such solution.
Pre-requisites
The participants should have knowledge on datacom net-working.
Training Structure
Two days training (1 day ATM, 1 day MPLS) divided into logical sessions.
Methodology
Instructor led training.
