2000 - 2001 Annual Report
MET NET
The Metropolitan Educational Telecommunications Network (M ETNET) is a distance learning
consortium consisting of 10 Twin Cities metro area community and technical colleges, Metropolitan
State University and the University of Minnesota. It is one of six higher education regional networks,
known collectively as the Learning Network of Minnesota, established by 1993 State enabling
legislation. METN ET serves its member institutions with a range of educational technologies to
enhance the delivery of programs and services between members and with other post-secondary
institutions in the state. The University of Minnesota serves as METNET ‘s fiscal agent.
Over the 2000/2001 academic year increased use of on-line course development software resulted in a doubling of the
number of courses offered in web available format from 179 in 1999-2000 to 318 in 2000-2001. The number of ITV
courses continues to grow from 73 courses the previous year to 82 courses delivered and received using this interactive
medium. In fact, the metro region remains a net exporter and importer of ITV courses, as no courses were shared by
member institutions in the metro region. Student e-mail accounts continue to grow. Student e-mail accounts will be
issued for life. Also a new web based e-mail program called WebMailPro was introduced with enhanced features such
as folders for message classification, address books and customizable user interfaces. The e-mail program is provided
courtesy of the University of Minnesota.
METNET added to the bandwidth capacity of each MnSCU campus in the consortium, increasing service to each
campus. Combined with the ongoing conversion to internet protocol based video, this has expanded the capacity and
availability of bandwidth for academic and administrative network traffic to all campuses.
METNET has worked closely with the MnSCU system office and the University of Minnesota in updating the metro
area network design to maximize the benefit of investment dollars. Lobbying activity for additional state legislative
funds in the 2001 legislative session, has provided increased monies through the Higher Education Services Office, for
modernization projects for our network infrastructure in the upcoming fiscal biennium.
This following report details the past year’s developments in M E TNET services and summarizes the distance
education activity undertaken by the network's Policy Board and the Technology Committee. The report concludes
with a look ahead to 2001/2002, and the challenges and opportunities of the next year.

Network Components
ITV Facilities
METNET provides a dedicated T-1 digital compressed video network connecting all participating campuses in the
metro area and a 3-site analog video network at Metropolitan State University. METNET has 21 digital video codecs,
linking 24 classrooms among the 12 member institutions.
During the past year, METNET, the State Department of Administration InterTechnologies Group and the MnSCU
system office have partnered to provide improved bandwidth capacity to all campuses in the consortium, increasing
from a minimum of one T-1 capacity to two T-1’s that have been aggregated to provide increased service and speed to
the internet (3 MB). MnSCU and the University of Minnesota have been integrally involved in planning these
improvements. Work has continued on moving our network to an ATM core backbone using Internet Protocol (IP)
based video and data streams. This will increase the efficiency of the network bandwidth and provide greater
flexibility in the use of the network (Attachment 1). Vendor equipment incompatibilities and the complexity of being a
technology innovator led to delays in the completion of this project. Project completion is anticipated in FY 02.
E-mail
METNET is the only Minnesota higher education regional consortium to provide a student e-mail service. Student email is currently available at all member institutions. There are currently 8500 users, approximately 25% of the eligible
FYE's (full year equivalents) with active accounts, many of whom are using e-mail as an integral part of program
course work (Attachment 2). Staff and faculty are also eligible for accounts. METNET introduced a web based e-mail
service (WebMail) to its users in the fall of 1999. In the spring of 2001, METNET introduced a new full-featured
webmail program (WebMailPro) provided by the University of Minnesota. It allows all students to access their e-mail
accounts from any location with internet access, such as college computer labs, public libraries, internet cafes, family
ISP providers, etc. A decision was made at the end of this current academic year to provide free e-mail accounts for
life to all eligible students, faculty and staff.
METNET Web Site
The METNET home page is located at http://www.metnet.edu. The design, featuring colorful clickable graphics as
menu items representing each M ETN ET service, has made it easier for visitors to navigate and find information.
Several new informational pages about our services have been added, as well as online request forms for both
Interactive Video and WebCT courses.
In addition to general information about METNET members and services, this site offers links to online resources such
as electronic reference tools, library databases and research tutorials. Course information for METNET programming
is available each semester.

Students initiate their e-mail accounts, change passwords and search the e-mail directory via the web page.
WebCT
WebCT is a web-based software program that facilitates the creation of worldwide web-based educational
environments. It can be used to create entire online courses, or simply to publish materials that supplement oncampus courses. Aside from facilitating the organization of course material on the web, WebCT also provides a variety
of tools and features that can be added to a course. This includes student progress tracking, online chat, course content
searches, bulletin boards, searchable linkable glossary, group project organization, student self-evaluation, grade
management and timed online quizzes.
The programmatic shift begun in 1997/1998, continued throughout the 2000/2001 academic year, to more web-based
course delivery. Since the Fall 1998 introduction of WebCT, the demand for training and course offerings has
continued to increase dramatically. Over 300 courses were offered this academic year. This number is expected to
grow next year, as there are over 500 courses already in development for next fall and spring.
To support the growth of this program, METNET has worked with campuses to provide training opportunities in the
use of WebCT. Features of the current version of WebCT have provided increased functionality and allowed us to
provide additional administrative capability at the campus level. A continuing trend has most campuses designating
an individual responsible for assisting faculty in the development of on line courses.
WebCT courses from Lake Superior College in Duluth and Rochester Community and Technical College were also
housed on our server. This service is provided for a fee.
Program Development
The number of courses offered as online courses increased dramatically since the introduction of WebCT in the fall of
1998. Initial course offerings totaled seven. The numbers have increased to 318 courses and approximately 8900
students registered and using web delivered courses during the past academic year. This total includes courses that are
offered totally online or use a web enhancement for a regular course (Attachment 3).
It appears that most online users are using campus computer labs to access their courses. Activity for online courses
occurs mostly during the regular class day. Heaviest activity on our WebCT server occurs between 7:00 and 3:00 pm
weekdays. There is a significant drop off in use in the late afternoon. It also should be noted that there is no period
during the day or night when no activity is taking place.

A comparison of courses from this academic year (2000-2001) to last academic year (1999-2000) shows an increase in
the number of ITV courses (Attachment 4). Eighty-two courses were offered for a total of 220 credits (Course
Schedules, Attachments 5,6,7). This past academic year provided another substantial increase in the number of courses
offered in the past two years, from 73 to 82 courses. Inter-regional activity (courses shared by metro and non-metro
institutions) continues to dominate the ITV schedule, accounting for nearly 100% of all activity. The only metro intraregional instructional ITV course activity occurs between Hennepin Technical College-Eden Prairie and the State
Women’s Correctional Facility at Shakopee.
Only one-half of our member institutions participate in ITV activity. Anoka-Hennepin Technical College and the
University of Minnesota are the most active participants. Anoka-Ramsey Community College, Normandale
Community College and St. Paul Technical College have increased their course activity this past year. Dakota County
Technical College and M E TNET received a Certificate of Commendation from the Office of the Governor for
innovative customized training program via ITV.
In addition to credit courses, METNET offered several non-credit ITV events such as professional development
workshops, seminars, customized training, administrative meetings and collaborative planning sessions.
METNET Administration, Organization and Funding
FY 2001 funding (Attachment 8) consisted of two grants from the Minnesota Educational Telecommunications Council
(METC), a network operational grant of $612,116 and a regional coordination grant of $58,333, in addition to a one time
supplemental grant of $91,000 for network infrastructure improvements. Additional revenue is derived from
membership dues and from hosting web courses for Lake Superior College and Rochester Community and Technical
College. A one-time enhancement grant to increase network capacity and convert to H.323 IP based video should be
completed this year.
As a regional network, METNET has developed relationships with the five other regional higher education networks in
Minnesota. On-going discussions include the development of policies and procedures to increase inter-regional
cooperation and collaboration.

Project Overview
METNET provides regional network services to 12 higher education institutions at 17 locations in the Twin Cities metropolitan area.
This network currently consists of single or multiple T-1 circuits from a single central hub to each location and shared network access
to the Internet, the MnSCU statewide backbone, and to MNET. The network uses time division multiplexing (TDM) to divide and
assign T-1 channels of 64kb/s each into H.320 video bandwidth and IP data bandwidth.
METNET has contracted with The InterTechnologies Group, Minnesota Department of Administration to be the network service
provider for the METNET regional network. MnSCU also uses InterTech for statewide data network services. InterTech has
partnered with the University of Minnesota to develop and maintain high-capacity access to the Internet and Internet 2.
METNET is moving forward with a network service re-design to accomplish the following:
1. increase network access bandwidth to locations needing higher speed IP data connections by adding additional T-1 or higher
capacity access facilities to locations,
2. add dynamic bandwidth allocation between the video and data applications in order to provide the highest-possible bandwidth to
data applications at all times,
3. add shared network bandwidth to the Internet; and to the MnSCU and U of M statewide backbone,
4. enable implementation of quality of service (QoS) protocols to support real-time multimedia communications over IP connections
within METNET,
5. partner with MnSCU and the U of M to extend QoS and real-time multimedia support across the statewide networks,
6. add support for user-initiated real-time multimedia connections for audio/video/data connections,
7. provide METNET locations with H.323 ready videoconference hardware and
8. support development of IP video/audio streaming technology for WEB-based communications.

METNET H.323 Video Communications
Get Ready for H.323 Video
Communications
H.323 Implementation in the Metro Region
across IP networks
Terry Kolomeychuk, METNET
Mark M. Nelson, InterTech
Greg Pedersen, Hennepin TC
MnSCU InformationTechnology Conference
April 18, 2001
What You Will Learn About:
•
•
•
•
H.323 video standards
Overview of the Metro video project
Wide area network requirements
Campus perspective
2
IP videoconferencing
standards - H.323
• Telephony Standards developed by the International
Telecommunications Union (ITU)
• H.323 is part of the “H” series of standards for
audio/visual communications over various networks
• Tightly linked to H.320 standard in wide use today for
videoconferencing over narrowband (T-1 or less)
networks
• Newer standard than H.320, still being deployed
• H.323 also includes a subset of audio standards for
Voice over IP
3
H.323 standards
• H.323 includes audio and video codec standards for
digitizing and compressing analog signals
• H.261 and H.263 are algorithms for video codecs
• G.711, G.722, G.728, G.729 are voice coding standards
• H.323 includes standards for multipoint (three-way)
connections and other signaling protocols.
• T.120 data conferencing may also be incorporated into
systems
• http://www.itu.int/itudoc/itu-t/rec/h/index.html
4
H.323 Standards Issues
• H.323 standards are in still in the early stages
of deployment by manufacturers
• IP data networks are packet-based and are
not readily adapted for real-time
communications
• H.323 standards do not fully address Quality
of Service (QoS) protocols that enable realtime communications over a WAN
5
IP Quality of Service
• For H.323 to be ready for standard
educational applications across WANs, IP
networks need to provide QoS to manage:
• latency
• packet loss
• jitter
• Protocols that support QoS across IP WANs
• RSVP
• IP Precedence
6
H.323 Application Components
• H.323 video endpoint from manufacturers
able to meet QoS requirements
• Cisco’s Multimedia Conference Manager
router software feature set provides
gatekeeper and RSVP management.
• The gatekeeper provides admission control,
bandwidth management, address resolution, user
authentication and authorization, call accounting,
and call routing functions for H.323 connections.
7
H.323 Application Components
continued…..
• Multipoint Control Units (MCUs) for bridging
three or more sites
• H.320 gateways for connecting H.323 sites to
H.320 sites
8
Benefits
• H.323 enables user-initiated connections
• H.323 permits dynamic bandwidth allocation
• data applications can use all available bandwidth when video
is not present
• H.323 integrates data and video transport
• ‘shared & bigger pipes’ for all applications
• network provisioning can be less costly
• Scaled bandwidth growth
9
METNET
• Provides network services to 12 higher education
institutions in the metro region
• Single or multiple T-1 circuits from a single hub
• Shared access o the Internet, the MnSCU statewide
backbone and MNet
11
METNET
• Network uses time division multiplexing (TDM) to
divide and assign T-1 channels of 64 kb/s each into
H.320 video bandwidth and IP data bandwidth.
