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

Final goal of this project

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 isnt 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 routers CPU charge
  
• After these adjustements DVTS transmission
  OK!!
  
• Its possible to increase tunnel MTU between RAP
  and RENATER by changing the tunnel end-point on
  RAP side
