  19. IPv6 multicast architecture • How UPMC site is accessing to the IPv6 multicast service for transmitting with DVTS ? • Logical path for IPv6 multicast from France to Asia • The M6Bone network : (http://www.m6bone.net) • What is the M6Bone ? • An IPv6 Multicast test network • M6Bone started in July 2001 (Aristote association, G6 and RENATER) • 28 networks & 50 sites • Goals • To offer IPv6 Multicast connectivity to interested sites • Test and develop soft and equipments related to IPv6 Multicast technologies • Be active in IPv6 multicast standardization • To deploy an advanced service on IPv6, in order to participate in the dissemination of the protocol

  20. M6Bone • Connectivity • IPv6 multicast is deployed natively in more and more networks • Need to bypass the routers not supporting IPv6 multicast (IPv6-in-IPv6, IPv6-in-IPv4, GRE tunnels) • Topology routing • MBGP • Static IPv6 multicast routes • PIM – multicast trees • PIM-SMv2 (requires MLDv1) and PIM-SSM (requires MLDv2) • Global RP in RENATER • Interdomain multicast • No MSDP available in IPv6 • Embedded RP under deployment • Applications and services : • Every IPv6 stack supports MLD and few applications use MLDv2 • Videoconferencing and diffusion : VIC/RAT, Videolan, DVTS, Isabel, WM player 9 • Radio broadcast : Freeamp • Others : NTE, WB, MAD, SDR • Reflectors • Monitoring • Connectivity / Traffic : ping, SNMP • Routing : AS-Path-Tree • PIM – Multicast topology : beacon and dbeacon

  25. Final goal of this project

  26. DVTS tests and results on french side • UPMC : • DVTS Sender is connected to RAP by a VLAN (MLDv1, rtadvd) • RAP : • IPv6-in-IPv6 tunnel MTU between RAP and RENATER is configured at 1280 Bytes : • No possible change • In IPv6 multicast, pMTU implementation fails on some equipments or isn’t available : • Problem if packet > 1280 Bytes : • Dropped by router because fragmentation should be made by the host using pMTU if necessary • Adjusting of packets size to transmit by DVTS with DIF Block paremeter : • By default : DIF Block = 17, packet size = 1360 Bytes • In our case : DIF Block = 14, packet size = 1120 Bytes • RENATER : • ipv6 mfib cef output enabled : reduction of M6Bone router’s CPU charge • After these adjustements : DVTS transmission OK!! • It’s possible to increase tunnel MTU between RAP and RENATER by changing the tunnel end-point on RAP side
