• Traditional AV - Challenges

• Converged Networked AV – Benefits

• AVB Standard, Components and Architecture

• Cisco Switching Support

• Deployment Examples

Messy - Point-to-Point – Unidirectional -Single Channel Per Cable - Inflexible

Organized - Many-to-Many - Multiple Channels Per Cable – Flexible -Scalable

o Distributed Timing o Bounded Latency o Reserved Bandwidth o Transport Protocol

Audio Video Bridging Standards based Plug & Play solution providing AUTOMATION for ALL of the above

Traditional Digital AV Network Media on AVB over AV Networks Cisco HW

Quality of Experience Scalability Lower TCO

. Improved time-synchronized . Ability to scale with higher . Lower cost and complexity audio/video (latency < 2/50 msec over bandwidth 1G/10G/40G (60% CapEx and 35% OpEx savings) 7 hops for a/v respectively) over 5 years* . Allows device interoperability . Standard QoS to simplify and automate . Added functionality and control . Eliminates proprietary networks switch configuration . No proprietary license fee per . Increases flexibility to add new .

Priority Queueing

Traffic Shaping

. AVB/TSN traffic shaping regulates the rate and bandwidth media traffic is allowed to use

. Egress priority queues supports Credit Based Traffic Shaper

. Dynamic configuration of Egress Shaper Rate - Per class and Per port basis for AVB core ports

Note: For non-AVB traffic, DSCP, PREC may be matched as well
