Internet Network Engineering Testbed (INET)

Core Infrastructure

This page details the core infrastructure used in our testbed.

Primary Research Network Router

milliways.erg.abdn.ac.uk is the router for the primary research network. It is a Cisco 3825 and acts as the router for the general use networks in our research labs and for our general use wireless network.

This router also serves DHCP and implements ACLs for the subnets that it serves.

This router is named after the resturant at the end of the universe.

Primary Sandbox Network Router

serenity.erg.abdn.ac.uk is the router for the primary sandbox network. It is a Cisco 1905 and acts as the router for the sandbox subnets. It is common for this router to route addresses on to a purpose built testbed for experiments.

This router also serves DHCP and implements ACLs for the subnets that it serves.

This router is named after the spaceship that appears in Joss Whedon's Firefly television series.

Switching Infrastructure

Our testbed operates a diverse range of Cisco and HP switches. Purpose-built extensions to the testbed may also have other switches included. We make extensive use of 802.1Q VLANs to isolate network traffic and use trunks between switches to ensure the right network is always available in the right place.

Not all of our switches are located within the server room or the labs, we also have remote test sites in other parts of the University campuses.

Main Distribution Switch

Our main distribution switch is a Juniper EX2200. This switch is directly connected to the primary research router, milliways, and also to our storage systems and server systems.

Labs Access Switches

Our labs are fed by two Cisco Catalyst 3750E (48-port each) switches. These switches are joined in a stack configuration and each switch recieves half of a 4Gbps LACP trunk from the distribution switch. These switches also supply the labs with PoE for Internet of Things experiments or for using other devices that can benefit from this.
