K-State IT Network Convergence

• Bringing it all together

2
Introductions

• Richard Becker, Network Technology Mgr.

3
Overview

• Procedures
• Current network and provided services
• Future Directions
• Redundancy / High-availability
• WAN - Internet/Internet2 Connectivity

4
Procedures

• Reporting network problems
• Call 2-7111
• Provide problem description, details, contact
  info
• Clearly indicate that problem is data
• New service
• http//www.k-state.edu/cts and click on Submit
  work order
• E-mail contact - for sending us information
• network_at_ksu.edu
• Ensures greater coverage / reduces response time

6
Routed protocols

• IPv4
• IPX
• Appletalk

7
Wireless Infrastructure

• Currently using WEP
• Guest wireless network in some locations
• Point-to-point links to Konza, Farms
• Mix of 802.11b, 802.11g, and 802.11a/g
• Stand-alone access points
• Voice runs across data WLAN, as does IPX

8
DHCP Services

• Currently have two DHCP servers
• Geographically isolated for service availability

9
VPN Service

• Currently a single Cisco 3030 appliance
• Site-to-site tunnel to CASHnet

10
Future direction

• Decision has been made to use Extreme
• Replacement of obsolete hubs and switches
• Need adequate space to house equipment / wiring
• http//www.k-state.edu/vpast/itpolicies/accomodati
  on.pdf
• Integration of data, voice, and video
• Interoperability between Avaya and Extreme
• IP Telephony adds new functionality
• Emergency notifications
• Mobility
• NISTAC voice installation is mostly VoIP, both
  wired and wifi
• Push functionality towards the edge of the
  network
• XML Interface / API for application integration

11
Future direction (continued)

• Connect buildings via gigabit ethernet
• Provide DHCP service to buildings rather than IP
  address allocations to departments

12
Current Extreme Deployments

• Nichols Hall
• NISTAC
• Jardine Building 9

13
Planning Future Deployments

• Datacenter
• Hale Library
• Jardine Complex
• Cardwell Hall (pending funding)

14
Resulting Changes

• Planning core replacement Summer 2007
• Supported / routed protocols after upgrade
• IPv4
• IPv6
• K-State now has an allocation of IPv6 addresses
• Unsupported protocols after upgrade
• IPX
• Appletalk

15
Wireless Infrastructure

• Move towards a Cisco controller-based environment
• Will require replacement of older APs
• Support for 802.11a/g
• Migrate away from WEP in near future
• Implement WPA2
• Transition period from WEP to WPA2

16
Wireless Infrastructure (contd)

• WEP will be retained for guests and hosts that do
  not support WPA2
• Access from this network will be much more
  restricted than from the WPA2-based network
• Separate Voice wifi network, likely WPA-PSK

17
Redundancy / High-availability

• Connect buildings to two core routers
• Fiber ring project
• First phase includes southeast portion of campus
• Should be completed June 2007
• Includes Hale and Power Plant core routers
• Dual border routers
• Peer with KanREN/GPN and ATT
• Add management capabilities to building UPSes

18
Redundancy / High-availability

• Wireless controllers
• Access points automatically connect to alternate
  controller in the event of a failure
• Controllers in Hale and Power Plant switches
• DHCP Services
• VoIP
• Redundant IP gateway interfaces in West Hall and
  Power Plant telephone switches

19
WAN - Internet / Internet2

• Current bandwidth
• Internet
• 105 Mbps via KanREN/GPN/Qwest
• 40 Mbps via ATT
• Internet2
• 45 Mbps via GPN
• Limitations of current scheme

20
Upcoming changes

• State fiber ring initiative
• Peering point for Internet2 relocating in August
• Abilene / NLR merger
