Issues & Challenges in Campus Wide Networking

• Campus Wide Network (CWN) interconnects networks in a limited
geographical area such as university campus.
• Emerging global economy require faster communication services and
improved productivity and effectiveness.
• Universities need to support demands and diverse issues.
• University network is required for its staff, faculty, students and
researchers to discover, learn, reach-out and serve the society.
Introduction
Arup Bhattacharjee, NIT Silchar

• Information Technology has been driving force in the development of
universities for some time now.
• A robust technical infrastructure and sound network architecture is needed.
• Network Architecture is the guide for the technical design of the network
using high-level design principles.
• Good network architecture meet and adapt to the specific need of the
university and also provide flexibility, scalability and manageability.
• CWN should support Next Generation Network (NGN) with integrated
services as well as Internet-of-Things (IoT) layout.
Significance

• CEO
▫ Marketable infrastructure
▫ Increase productivity – publication, student intake
▫ Fund
• Network Administrator
▫ Faster provisioning
▫ Ease of maintenance
▫ Availability
• End User
▫ Speed
▫ Reachability
Perspective

• Improve student outcome using technology
• Funding strategy for IT growth
• Organizational model for openness and agility
• Sustainable strategy for online learning
• Leveraging device explosion
• Use of cloud based solution
• Balancing between openness and security
Issues

• Mandatory requirement for accreditation for funding.
• Act as a performance measure of system, institution and department.
• Leverage technology for design, creation and delivery of learning experience to the
students.
• Use technology for face-to-face, blended as well as totally online learning.
• Use of services such as Google+, iTunes, Youtube etc. but challenge is lack of policy
for IPR, privacy issues, quality etc.
• Use of open educational resources such as MIT OpenCourseWare, Khan Academy,
MOOCs etc. challenge is to identify and select quality resource, creating new
material etc. by the faculty.
• Using social networks such as Facebook, Twitter etc. for connecting students at the
course, program and the insttute.
Student Outcome

• IT is a service to the university much like Academic, Student Administration,
Finance and Accounts etc. – not to be treated in isolation.
• An operating model is needed based on existing business process in order to
position IT.
• One may view IT both as cost center as well as revenue generator.
• Investments need to be made based on expected organizational
transformation and strategic growth.
• Develop a cost metric to assess cost of each IT Service.
• Need a strategy for identifying areas of technology adoption and innovation.
• Draw policies for leveraging local resources for enabling collaboration.
Funding

• Cloud Computing, BYOD, e-Governance, Analytics are new demands.
• Demands arise from ERP or LMS system of the institution and the level of
support needed.
• Traditional computer labs, classrooms must be supported while exploring and
integrating newer technologies.
• As institutions move to outsource more solutions, staff need to assume new
roles and form new units for service management and strategy.
• Will the institute be able to adapt to dynamic environment?
• Fund crunch often require smaller units to be consolidated towards
centralization with more specialist and fewer generalist roles.
Organizational Model

• Massive Open Online Course (MOOC) is here for supporting design and
delivery of quality leaning experiences.
• Institutions need to understand about goal, audience and quality of
experience in their MOOC endeavor.
• Institutions need to balance between broad availability of online courses vis-
à-vis restrictive approach.
• Right scope and positioning of the online courses is very important.
• Faculty need to adjust to the new way of instruction; a deviation from purely
lecture based model of course delivery.
• A well developed assessment strategy is needed against online courses as
traditional pedagogical theory do not hold any longer.
Online Learning

• Bring-Your-Own-Device (BYOD) trend is rising and is supported.
• Challenge of network coverage has been surpassed by the bandwidth requirements
due to density of devices.
• Upgrading of devices more frequently is the newer challenge.
• Providing contents ranging from class schedule to campus news to faculty, staff and
students anywhere, anytime and on any device is the biggest challenge.
• Wireless technology is adopted for ease of deployment.
• But, what will be the security implication, is sufficient Internet bandwidth available,
is instructional model is being affected, should mobility be supported?
• Should the institute support mobility and if so, does it need custom application?
Device Explosion

• One of the fastest changing aspect of the industry.
• Software-as-a-Service (SaaS) model is now being adopted.
• Proper cloud computing framework can make institute more agile in
delivering newer service faster yet keeping upfront cost low.
• Initiatives such as Internet2 provides an opportunity for institutions to
collaborate for developing fair legal and business contracts, share experience.
• Platform-as-a-Service (PaaS) model is easier to deploy while Infrastructure-as-
a-Service (IaaS) model may require more planning and integration.
• Stable policy is needed to ensure data security, data location, who has access
and to what, recovery point objectives and recovery time objective in the
event of disaster.
Cloud Strategy

• Safeguarding data and protecting privacy of higher education community.
• Equity, diversity and sharing define higher education.
• Community such as REN-ISAC provide security watches and remediation
information.
• Institutions should have formal risk management process.
• A formal process for data classification is needed for sensitive data.
• A review mechanism for security practices/policies/processes need to be in
place for guaranteeing reasonableness.
• Identify, review and remediate if security practice is inhabiting collaboration.
Balance of openness and security

• These diverse issues are not independent.
• Emphasizes interaction among institutional policies, transformation towards
IT and external forces.
• Clearly external forces influence institutional priorities but are reshaping
higher education IT.
• A more direct connection between external forces and university IT is the
matter of openness versus security, adoption of cloud technology.
• A key requirement is therefore is the ability to aggregate, de-aggregate and
re-aggregate resources, services and applications of every component of
research and education.
• A well developed network architecture is expected to meet this requirement.
Lesson

Parameters of CWN:-
• Large network over broad geographies.
• Constantly changing large user base.
• Wide variety of network devices in terms of OS, make, type etc.
• High volume of large file sharing and downloading.
• Open network.
• Track user for copyright infringement, cheating etc.
• Breach of network security.
• Varieties of applications and databases accessed.
Network Administrator’s Corner

• Decide about architecture to be deployed.
• Work-out implementation strategy.
• A well planned commissioning timeline.
• Human resource requirement and its sustenance.
• Plan for maintenance schedule.
• Roadmap according to expansion plan.
• Disaster recovery plan.
• Response mechanism towards IPR violation, virus outbreak, network
slowdown etc.
Challenges

• Hierarchical or flat network?
• Routing or switching or hybrid?
• Single OEM or multi-vendor?
• Wired or Wireless or both?
• Data network or convergent network?
• Open access or restricted access?
• Logging or no-logging?
