Nortel Wrote the Book
on Real-Time Networking (literally!)
> For mission-critical applications, “best-effort” of
data world is not acceptable
> Not all networks can support real-time
applications
> Expert network planning and design is required
> “The Book” – 800+ pages; technology/standards
focused
