Layer 2 Multicast at the Edge
Page 8
• Internet Group Management Protocol (IGMP)• IGMP Proxy• IGMP Snooping

Video Lab
Page 10
• Upgrades can cause major issues• Upgrades should be tested before putting on production
network• Many companies have a dedicated Video lab
• Apply upgrades in lab first• Run several tests to ensure proper behavior

Video NOC
Page 11
• Dedicated Video Network Operations Center (NOC)• Technicians can see issues in real time• Correlate to what is seen in logs/monitoring

Video Test Points
Page 12
• Video monitor feeds from multiple points in the network• Allows technician to pinpoint where issue resides in
network

Video Monitoring
Page 13
• Alarming and Monitoring video networks is critical to troubleshooting
• Monitor packet loss and alert on errors• Several Video monitoring solutions available:
• Cisco Vidmon• Ineoquest• Sencore• Other vendors
• Network element monitoring• Solarwinds• Intermapper• Nagios• Cacti• Other vendors

Vendor Instability
Page 16
• Hard to foresee the future of certain vendors• Discontinued products• Vendor product lines being sold/discontinued
• Cisco Flip Video Camera and Umi• Ericsson SmartEdge• Nortel CS1500—Genband C15
• Quality of support for acquired products

Single-Vendor Network
Page 17
• Is a single-vendor network the solution to reduce risk?• Best of Breed
• Wal-Mart of Networking• Supporters think a company can reduce risk if integrating
single-vendor into network• Simplifies network• Lower interoperability testing costs• Fix issues more quickly• Lower OpEx
• What if that vendor is acquired or goes bankrupt?• Ongoing technical support programs may cost more

When Purchasing New Products
Page 19
• Request for Proposal (RFP) Process• Vendor pricing is not only thing to look at:
• Vendor financial stability• Obtain client references and discuss product with them• Determine product life cycle• Onsite technical sessions• Demo or try-and-buy in own network• Onsite Proof of Concepts (PoC) with vendor• Interoperability Tests (OJT)• Cross your fingers

How to Keep Equipment in Service Long Term
Page 20
• Purchase “future proof” equipment• Long life cycle
• Check for End of Life (EoL)• Subscribe to EoL Notifications
• Product roadmap• Spares• Scalability
• Extended warranties• Explore cost effectiveness of purchasing up to 5 years or more• Price is locked in for life of product• If vendor acquired, support contract is generally honored.
Renewals are another story• Be wary of purchasing ‘Gray’ market equipment
• Recertification• Software RTU fees

Required Standards Support
Page 21
• PIM Routing• Protocol Independent Multicast-Sparse Mode(PIM-SM)• PIM-SM Source Specific Multicast (SSM)
• SSM Mapping IGMP v2 to v3• IGMP v2/3
• IGMP Proxy• IGMP Snooping
• Multicast VLAN Registration (MVR)• IPv6 Protocol Suite• IEEE 802.1ag/ ITU Y.1731• 10Gig/40Gig/100Gig

Performance-based Contract
Page 22
• CYB-Such as RUS suite of contracts• Good contract is critical to avoid issues when
purchasing vendor solutions • Contracts should include:
• Contractor’s Bond• Required Standards Compliance• Installation Requirements• Final Acceptance Testing Requirements
• Burn-in• RFC 2544 Ethernet Testing• Failover• Any other tests as required
• Project Timeline• Payment Guidelines (90/90/10)

Federal Regulations
Page 24
• FCC NPRM regarding ICC and USF• Changes compensation methods for carriers
• Net Neutrality• Affects network management policies• Affects Service Level Agreements (SLA)

Conclusion
Page 25
• Video, Internet, and Voice networks are bleeding together• Test video upgrades in a lab before putting into production• Monitor video in real-time• Vendor instability is a concern for companies• Utilize RFP process when making major equipment
purchases• Must purchase “future proof” solutions by reviewing
specific information about the product• Consider purchasing extended warranty to cover intended
lifespan of solution• Ensure solution is in compliance with certain standards• Utilize performance-based contracts to safeguard
investments• Consider federal regulations when making investments

Final Thoughts
Page 26
• The industry is ever-changing and companies need to understand how to protect their investments
• Everyone is for sale for the right price and anyone can go bankrupt (i.e. Nortel)
• Need to prepare for unforeseen events by being informed and doing your research
• Using performance-based contracts can save you future headaches
• Some luck is involved
