New network design

I have start a new job last December and the project consist in designing a network for a new airport. This airport has the ambition to become the “airport of the future” and my employers want to use this project as a showcase.

The network will have to carry different type of traffic, Voice, Video (Security camera), Video (Public IP TV), Public Internet access via wireless. The site have 2 Data center and up to 7K access ports scattered across the sites.

In the Data center, we will install 2 Nexus 7018 switches that will be our core and aggregation. The servers will be on the Cisco UCS platform and will be connected using a Cisco 9140 fabric extender as well as Nexus 5000 and 2000 switches. This will be my first project using the Nexus switches as well as with the UCS.

20 out of the 28 wiring closets will be equip with Cisco Catalyst 4510 dual connected to the DC with 10G Ethernet links. The wiring closets vary from 96 ports to 768 ports. The smaller wiring closet will be equip with Cisco Catalyst 3750X.  Every ports in the wiring closet will be POE enabled.

So far, the wiring closet will be connected via L3 to the DC and we choose to run OSPF as a routing protocol, mainly because we want to have a open routing protocol in case we interconnect with other manufacturer.

Having the luxury to start a completely new network, we were able to design an IP scheme that will be hierarchical, so each wiring closet will be in there own OSPF area and only a summary will be advertise to the core.

IPv6 will be be implemented as our internet link will most likely install after the IPv4 address exhaustion.

We are currently completing the 1st order and we are getting ready for installing all the equipment into our staging location

I will update the blog with the experience good or bad over the next months

    Wow, des heures de plaisir. Avec IPv6 en plus!

    Will the Public wireless Internet be free for those within range?

    Will it also be available to people grounded in airplanes?

    Beside the learning curve, because IPv6 provides new functions and security features, is it cheaper and faster to design the solution?

    Merci.
