Field Trial: Virtual PC over OPST Ring on Field TrialIntune Configuration • Two virtualization servers are connected to Netgear switches, which in turn connect to Intune Beta nodes 1 and 3 in the symmetrical ring of 5 Km. span per segment. • The ring is formed by three Intune Beta nodes and one of them serves as a pass-through (node 2 in the picture). • The Netgear switches provide interface between the Server 1G ports and the 10G client interfaces on the InTune Beta nodes.

Field Trial: Virtual PC over OPST Ring on Field TrialIntune Management System • A PC was also connected to the LAN to support configuration and management allowing for the following: • When the three-node ring were powered up, the power levels had to be calibrated optically. • Bit error test, where PRBS test data is generated before action data traffic is allowed on the ring. • MAC addresses configuration. • Master Node Selection and Service Mode Initialization. • Virtual Connections Setup.
Field Trial: Virtual PC over OPST Ring on Field TrialApplications Setup • A number of Virtual Machines were created on a single Laptop connected to the prototype network with real user interfaces. • With the Virtual Machine Application we were in position to create a number of Virtual Machines, shut them down, modify them and if necessary transfer them where necessary from one server to another. • Figure 1 (left) shows the login at MAINS Virtual PC Homepage • Figure 2 (right) shows the user friendliness of the application where on is able to indicate on a map the selected destination and hence server location. Server selection can be achieved through this interface. The orange smiley icon represents us, blue server is the selected server, and red servers are available servers
Field Trial: Virtual PC over OPST Ring on Field TrialUse Case Scenarios • Quality of Experience of Scenario 1: In this use case scenario, the user is accessing his virtual machine from local server on the same network and hence experiences optimum performance. • Quality of Experience for Scenario 2: In this scenario the user is accessing his virtual machine from remote server located approximately 11km away. The quality level experienced by the user was not much different to the first scenario with very minor jitter experienced due to the transport layer protocol. • Quality of Experience for Scenario 3: In this scenario, we tested the transfer of a virtual machine from a remote to a local server, while a mobile user changed its point of access from one location to another. The handover time experienced by the user on the application level was mainly due to the copying time of the virtual machine caused by the transport layer protocol.
