Title:    IP Application QoS on a Carrier Network
Speaker:  Eric Voit
          Distinguished Member of Technical Staff
          Verizon (formerly BellAtlantic)
When:     November 8, 2000 - 10 am
Where:    Interschool Lab, CEPSR Building, 7th floor
          Columbia University

Abstract:

Fiber topologies, Operations costs, regulation, tariffs -- these are not
the first items which come to mind when people think about application
specific IP QoS.  Yet these items are critical when deploying affordable
metropolitan access networks that incorporate IP QoS mechanisms.  This
talk will start with an overview of key disruptive technologies which
are changing the nature of metropolitan IP networks.  Of specific focus
will be recent advances in line speed router technology and Layer 2/3/4
ASICs, Gigabit Ethernet and anticipated cost curves, 802.3ad trunking,
and MPLS.  These are the emerging technologies which are making shared
IP QoS networks technically viable.

After technical viability has been established, the presentation will
move to environmental and economic factors which will impact different
types of deployments.  Highlighted will be the transport facilities
available to DLECs and some relative costs.

The talk will conclude with an interactive discussion on how different
IP applications might be overlaid on a different types of metro IP
infrastructures.

Biography:

With thirteen years of telecommunications experience, Eric has held
various positions at Verizon within the Technology, Information Systems,
and Operations organizations.  For the last two years, he has
concentrated on local IP Network architecture designs which can meet the
QoS needs of VoIP, video, VPN, multicast, Internet access, and other IP
applications.  During the previous three years, Eric was heavily
involved with VoIP, and architected the first commercial offering from
an ILEC.  Eric has been awarded eight United States patents relating to
Internet Telephony, Advanced Intelligent Networking, Central Office
switching, and the databases of Operations Support Systems (OSS).  Eric
has an M.S.  in Technology Systems Management from University of
Maryland, University College, as well as a B.S.  in Computer Science
from Lafayette College.
