Provide the end-to-end service definitions An important ATM standard is interworking between ATM and frame relay Two ATM networking standards 1)broadband intercarrier interface (B–ICI) 2)public network-to-network interface (P–NNI) DATA INSERTION SCHEMES : 11 DATA INSERTION SCHEMES RFC1483-specifies how interrouter traffic is encapsulated into ATM LANEMPOA- support dynamic use of ATM SVCs voice and video adaptation schemes-for efficient traffic that no natural breaks, such as a circuit carrying bits at a fixed rate ATM LAN EMULATION(LANE) : 12 ATM LAN EMULATION(LANE) LANE components 1)LANE clients 2)LANE servers VIDEO OVER ATM : 13 VIDEO OVER ATM Handled by VBR–RT VCs using AAL–5 for MPEG2 on ATM for video-on-demand applications MPEG2 coding can result in two modes: program streams—variable-length packets carrying single or multiple programs transport streams—188-byte packets that contain multiple programs Time stamps are inserted into MPEG2 packets during the encoding and multiplexing process to make better use of networking resources. VOICE OVER ATM : 14 VOICE OVER ATM VBR–RT connections is used over ATM which uses silence period. Various dynamic compression techniques are used to free bandwidth and alleviate congestion A further enhancement is to support voice switching over SVCs which interprets PBX (private branch exchange) signaling and routing voice calls to the appropriate destination PBX NETWORK TRAFFIC MANAGEMENT : 15 NETWORK TRAFFIC MANAGEMENT objectives :To deliver quality-of-service (QoS) for multimedia applications and provide overall optimization of network resources. categorized into three distinct elements nodal-level controls that operate in real time network-level controls operate in near real time network engineering capabilities operating in non real time ATM APPLICATIONS : 16 ATM APPLICATIONS ATM AND IP INTERWORKING : 17 ATM AND IP INTERWORKING ATM and IP offer: Scalability, traffic engineering, service differentiation, high availability, value-added applications such as Virtual Private Networks (VPNs) Some specifications of ATM and IP Multi-Protocol over ATM (MPOA) as addition to LAN Emulation (LANE) Additions to ATM's superior routing protocol PNNI adoption of Frame-based ATM over Sonet/SDH (FAST) CONCLUSION : 18 CONCLUSION ATM technology is the only technology that can guarantee a certain and predefined quality of service. The growth of the Internet, need for broadband access and e-commerce are spurring the need for a reliable, flexible, scalable, predictable, versatile transport system and that is given by ATM Technology. For voice, video, data and images together, the next generation network depends on ATM. Slide 19: 19 THANK YOU You do not have the permission to view this presentation.
