3 shows a representation of the layered and indirect lines of communication that occurred when the network provider worked with the jurisdictions where IT services were outsourced. This dynamic was particularly in evidence in engaging with the network management model in place in South Australia. It resulted in there being several layers between the PoCN practitioners and project representatives and the outsourced technical staff who actually implement the required changes. Figure 3 represents the communication flows for the Dental Hygiene Project and the setting up of the VPN. Figure 3 Project Communication Example 3.1.1 South Australia South Australia has a strong whole of government culture for contract and network management, with centralised network management and a tiered set of firewalls. This had significant impact on the project timelines and consequently the ability to conduct applications projects. In addition the resulting convoluted network design meant South Australian VET practitioners did not benefit from being part of the PoCN to any great degree during the course of the Project.

After some long delays relating to negotiations over Terms and Conditions of Service, the standard AARNet Access Agreement was signed in June in its original form with no amendments made. The design of the interface between AARNet and SAuGov networks had to be customised to meet the terms set by the Department of Transport Energy and Infrastructure (DTEI) who run the State ICT Services Group and manage StateNet, South Australia’s WOG. These terms did not allow normal inter-network exchange of routing information and did not allow inbound connections into the TAFE network. DTEI and their outsourcer (Dimension Data) refused to allow any form of dynamic routing exchange between the state network and AARNet so all changes were manually made with iterative changes to static routing and Network Address Translation rules based on observation of what was and was not working and individual work orders. It was pointed out early that videoconferencing is generally incompatible with Private IP addressing and Network Address Translation (NAT) unless some form of proxy or firewall traversal device was used. All other PoCN members had a connection to AARNet using Border Gateway Protocol (BGP) Routing which AARNet uses to assign customers to particular communities and decide which communities have routes between each other.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
