UCT Campus Network Upgrade Network Blueprint University of Cape Town supaTsela PIC 14 July 2005
Current network: risks and deficiencies • Outdated and hard to update • Uneven mix of technologies including legacy connectivity • Cannot deploy new services required by UCT quickly enough • Difficult and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 Traffic Analysis Network design Migration plan Business workshops As-is • 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
Outdated Hard to update Difficult and costly to manage Cannot be properly secured Not sufficiently reliable As-is and to-be compared As-is To-be • Fully switched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 • Managed switches from a single vendor that have enhanced security features • Enhanced availability through managed network components and redundancy. The new design supports consistent service-level improvements in networking services across campus.
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
Recommendations: • That PIC approve implementation of the UCT Campus Network Renewal and Upgrade as per the recommendations contained in the Network Blueprint document and associated documents. • That PIC note and approve the revised budget in respect of the Network Upgrade in Academic and Administrative Buildings.
UCT Campus Network Upgrade Proposal to contract with T-Systems as the Implementation Partner University of Cape Town supaTsela PIC 14 July 2005
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.
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
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).
UCT Campus Network Upgrade Proposal to contract withT-Systems for the Maintenance of the Network Core Switches University of Cape Town supaTsela PIC 14 July 2005
Cisco Shared Support Program (CSSP) • CSSP is an offering through which Cisco and channel partners provide technical support to customers • CSSP must be purchased on all products at time of order • CSSP can selectively be renewed in the second year and onwards
Benefits of Cisco Shared Support Program • Online access to Cisco technical support • Access to software upgrades and bug fixes • Best effort warranty replacement through partner
T-Systems’ Maintenance Proposal • ObjectiveProvide UCT with a hardware maintenance contract for mission critical hardware components. • Benefits- Minimum client network downtime- Fixed cost budgeting in an unpredictable environment- Spares holding facility • Service OverviewA Platinum Service Level Agreement with a Guaranteed Mean Time To Restore (GMTTR) of 4 hours
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.
