Current network: risks and deficiencies
• Outdated and hard to update
– Uneven mix of technologies including legacy connectivity
– Cannot deploy new services required by UCT quickly enough
• Difficult and costly to manage
– Does not conform to a standards-based model
– Staff time is spent reactively on support and maintenance
• Cannot be properly secured
– Security incidents cause significant downtime
– Lack of structured security policies to govern network access
– Unmanaged switches and hubs cannot be properly secured
• Not sufficiently reliable
– Lack of fault tolerance - no redundancy on the backbone

Network design methodology
• As-is network documentation: extensive information gathered on access ports, cabling, services, environmental conditions
• Network traffic analysis: traffic flows and volumes baselined
• Business requirements: discussions held with major UCT business units; information gathered via a questionnaire
• “To-be” network design
• Phased migration plan: the future network will be built alongside the existing network with a gradual conversion of users

To-be design: layered network model
• Three main building blocks: core, distribution and access layers
• User workstations connect to access layer switches
• Access switches in turn connect to distribution layer switches which act as aggregation points
• The core layer provides for connectivity between the data centres

To-be design: wireless
• Provision made for about 30 secure wireless hotspots on all campuses.
• Locations determined based on
– questionnaires returned
– information from P&S about open access areas

Future proofing
• The new design has the capacity to incorporate new technologies in the future and at additional cost
• The most likely future technologies for possible implementation at UCT were analysed:
– IP Telephony
– Voice over IP (VOIP)
– IPV6
– Content Networking
– IPTV

As-is
• Outdated
• Hard to update
• Difficult and costly to manage
• Cannot be properly secured
• Not sufficiently reliable
To-be
• Fully switched network infrastructure with enhanced performance and throughput
• Capacity for future growth and technologies
• Pro-active central management to resolve problems and reduce costly downtime

Blueprint scope exclusions
• Internet bandwidth
• 1Gbps connectivity to the desktop
– The design model allows for this
– It has not been included in the budget
– The additional costs of such connectivity will be for the account of the user
• Issues addressed by the NIR workstream, but not part of the blueprint:
– WAN (Wide Area Networking) links
– Cabling within and between buildings
– Residences

Proposal to contract with T-Systems as the Implementation
Partner
![Page 13: UCT Campus Network Upgrade University of Cape Town supaTsela PIC 14 July 2005 Network Blueprint](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649cf05503460f949be927/html5/thumbnails/13.jpg)
- 13 -PIC 2005-07-14
T-Systems as a partner in Phase 1 of the Network Implementation
• T-Systems overall performance was satisfactory
• Their technical competence and performance was good
• We have established a good working relationship with the T-Systems team
To switch to another partner for Phase 2 (implementation) of the Network Renewal would result in significant delays, could be more expensive, and does not appear justified in view of the comments above.
![Page 14: UCT Campus Network Upgrade University of Cape Town supaTsela PIC 14 July 2005 Network Blueprint](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649cf05503460f949be927/html5/thumbnails/14.jpg)
- 14 -PIC 2005-07-14
Proposed scope of work for T-Systems (in conjunction with UCT)
• Implementation of Network Management Systems (CiscoWorks and HP OpenView Network Node Manager)
• Implementation of Cisco Access Control System
• Implementation and testing of a pilot network which will include the full core layer and the distribution and access layers for a Model-A Building (Commerce) and a Model-B building (Menzies) as a B-model and the HSF Lab in Anatomy as an A-model at Medical School
• Development of the Migration templates
• Full Rollout of the Core Layer and all the Distribution Layer in Model-A Buildings together with the first two Model-B Buildings
• A quality assurance role throughout the network rollout

- 15 -PIC 2005-07-14
Recommendations:
• That T-Systems be awarded a contract to provide services as per the scope definition in the previous slide.
• That the supaTsela Project Team be authorised to negotiate the cost of this contract up to a maximum value of R 750,000 + VAT (current indications are that it will be substantially less than this).

Recommendations:
• That UCT should contract with T-Systems for the maintenance of the Core layer equipment.
• That the supaTsela Project Team be authorised to negotiate the cost of this contract up to a maximum value of R 600,000. This is based on 15 months of a monthly paid three year contract at $1=R7.5.
• That UCT should hold stock of the Access and Distribution layer equipment to provide for rapid replacement of any defective equipment.
