InfoComm 2012 The Unified AV Network • How does AVB impact IT?
Agenda • Who/What/Why is the AVnu Alliance? • What is the importance of AVnu Certification? • What is the importance of AVB in A/V networking? • How does AVB impact IT
Agenda – Other Sessions • Sessions throughout InfoComm include: • A/V Installations with AVnu-Certified AVB: Start Fresh with Interoperable Devices • AVB for House of Worship: Tap into the Simplified A/V Network • AVB Must-Knows for the IT Pro • Live Events with AVB: How Will One Open Standard Set Change A/V Networking? • A Technical Deep Dive: Uncover the Mysteries of AVB • AVnu AVB Manufacturer Symposium: Ready for a New Networking Ecosystem?
What/Who is the AVnu Alliance? • The first industry forum to lead the adoption of open IEEE standards based AV Networking • AVB (Audio/Video Bridging) is the first set of AV networking standards approved by IEEE • A non-profit organization defining AVB Certification and Promotion • Members include major Automotive, Pro AV, Consumer and Silicon/Platform Manufacturers • Member manufacturers are given access to test tools and plugfests in advance of submission for official AVnu interoperability certification.
What’s the importance of AVnu Certification? • Certification is key to a no-compromise A/V network that is easier to implement than ever before. • Certification provides a marketable assurance that AVnu-certified devices will be interoperable.
What is the importance of AVB in A/V networking? • The AVB standards are written by the IEEE, the group that defines Ethernet • AVB is royalty free and open for use by anyone • Network engineers have tools to accommodate AV requirements • Precise and reliable, suitable for rigorous professional applications • Data pathway from source to destination is guaranteed • Low latency • Synchronized
Why Audio Video Bridging (AVB)? • Moving to Ethernet solves cabling issues but: • Introduces latency/guaranteed bandwidth and synchronization issues • Dante, Cobranet are proprietary solutions on top of Ethernet to address these issues • AVB • Is based on new IEEE Ethernet standards • It is open and interoperable so any vendor can support it • With AVNU that interoperabilty is certifiable
What’s great about AVB? • Synch accuracy of +/- 500 nanosec over 7 hops • Latency of 2 ms for Class A and 50 ms for Class B • Complex installs become simple • Multivendor • IEEE standards based • Interoperability certified • Attend this presentation for how AVB works: • A Technical Deep Dive: Uncover the Mysteries of AVB
AVB Requirements? • Ethernet switch (AVB bridge) must support AVB - Requires AVB supporting chip - Requires software to enable the chip & run AVB protocols - Helps to have AVnu cert. so it interoperates • AVB Endpoint (mic, speaker, console et al) must support AVB or connect to an AVB snake • So which switches? • Harmon, LabX and Extreme Networks are being demoed at the show
What is the Impact on Other Traffic? • AVB will take the two highest levels of QoS on your switch • AVB defaults to take 75% of a link but can be dialed down to zero • AVB can apply to Video as well as Audio singularly or mixed • For a converged network: All non AVB traffic (VoIP, IM, Building Control Systems) goes in lower QoS levels • It works with one subnet
Layer 3 and AVB • No L3 protocols have to be disabled or configured to support AVB • There are use cases where L3 is desired (ex: very large theme park with many subnets) • AVnu Technical Working Group is addressing this and IEEE activities
Cabling… Power… Speeds • AVB will run over Cat 5 up to 1G. Cat 6 for 10G over copper • 10/100/1000 Mbps and 10G over copper or fiber. 40G over fiber • 10G and 40G needed for uncompressed video • Non-PoE, PoE, PoE+ • From 5 ports to thousands in stackables or chassis. There are use cases where L3 is desired (ex: very large theme park with many subnets) • Lockable connectors desired in some installs • Switches demoed here cover these capabilities
AVB Training • From AVB vendors • Potentially from the AVnu alliance
Cost and Availability? • Please see our switch partners here at show or on their websites for costs and availability • Harman (BSS Audio/Netgear GS 724T) • LabX (Titanium 411) • Extreme Networks (Summit 440X, Summit 460X, Summit 670X)
Summary • Supporting ProAV gets easier for IT with AVB • Switches and endpoints supporting AVB are required. • Some products are available now. • The selection will increase as more vendors turn-up AVB • AVB fits well with other network traffic
