Service agility and performance

• The application of NFV and

SDN technologies to video processing and distribution

• Flexible pool of resources on

which media functions are deployed

• On-premises or in the cloud
• The TCO per channel is up to

50% lower than with appliances.

Virtualized HE Solution

• Vendor agnostic framework

to introduce 3rd party media functions as a VNF / plug-in

• Interfaces through open and

well defined APIs

• Resource management:
• Instant provisioning of

channels

• Dynamic recycling of

resources for other services

• Workflow management

Multicast and zero packetloss

Unicast

16

• One-to-One
• TCP/IP

Source Receiver Receiver

Broadcast

17

• One-to-All
• Common (ARP, DHCP, etc.)

Multicast

18

Source Receiver Receiver

• One-to-Many
• Like Pub/Sub

Multicast addressing

19

• IPv4 224.0.0.0/4
• 224.0.0.0 to 239.255.255.255
• Subdivided for specific purposes
• Administratively scoped: 239.0.0.0/8
• Multicast MAC addresses

IGMP

20

• Internet Group Management Protocol
• IPv4 protocol to manage multicast group membership
• Hosts can join/leave groups and send membership reports
• Multicast routers can query hosts for membership reports
• Three versions – IGMP v1, v2, v3

Multicast and OpenStack

21

• Neutron has no API for multicast
• Support depends on plugin/driver
• ML2/OVS and VLAN provider networks
• Neutron does L2 only. Physical routers do L3.
• OVS 2.4+ supports IGMP v1, v2 and v3
• Works with local controller and NORMAL action
• ML2/OVS VLAN works this way
• Default IGMP disabled and multicast is flooded

Multicast and ML2/OVS VLAN

Zero Packet Loss

24

• Packet loss reduces video quality
• Transcoding is CPU intensive
• Packet handling for VMs requires host CPU
• CPU pinning
• Huge pages
• OVS-DPDK
• Vhostuser more efficient
• PMDs use dedicated cores

Problems

25

• Transcoder fast restart fails
• Failure to receive stream
• Duplicate packets on VLANs
• Bugs fixed in OVS 2.5+ branches
• Use iperf v2 and pimd to recreate
