UCT Campus Network Upgrade

UCT Campus Network Upgrade
Network Blueprint
University of Cape Town supaTsela PIC 14 July
2005
2
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• Outdated and hard to update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

3
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

4
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

5
To be design core
6
To-be design four building models
7
To-be design wireless

• Provision made for about 30 secure wireless
  hotspots on all campuses.
• Locations determined based on
• questionnaires returned
• information from PS about open access areas

8
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

9
As-is and to-be compared

• Outdated
• Hard to update
• Difficult and costly to manage
• Cannot be properly secured
• Not sufficiently reliable

• 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.
10
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

11
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
13
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.
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
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

17
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

18
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

19
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

20
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
  1R7.5.
• That UCT should hold stock of the Access and
  Distribution layer equipment to provide for rapid
  replacement of any defective equipment.
