Nt1310 Unit 6 Lab Report

The goal of this lab was to expand and centralize our infrastructure by adding a Windows Server 2012 VM and configuring it with a number of key services. Some of the services that we deployed on the Windows 2012 VM had previously been configured on other machines, namely the RHEL VM from Lab 2. We began by installing and configuring the server itself, ensuring that we provided it with ample memory and processing power. Next, we configured DHCP, disabling the DHCP service running on our RHEL VM. We then continued by installing Active Directory and DNS on the Windows 2012 VM, disabling the DNS server running on the RHEL VM in the process. The DNS server on RHEL would later be reactivated as a secondary (slave) server. We then proceeded to set up monitoring for both DHCP and DNS. This monitoring was configured locally on the Windows 2012 VM using the Performance Monitoring utility, and also remotely via OpsView. Finally, we installed Microsoft Baseline Security Analyzer on the Windows VM. This was the first lab where it felt like we

The bitlockertogo.exe is an executable file in PCs with Microsoft Windows XP, 7, MAC operating systems installed in them, errors are associated with Microsoft bitlockertogo exe mui, bitlockertogo.exe autorun.inf and to fix them the PC users can free download, install and use BitLockerToGo.exe error repair tool like VSKsoft.

Remove the cockroach from it habitat and submerge it in ice water for a few seconds to paralyze it. After the cockroach is paralyzed, using the surgical tools cut a leg (at the hip). The leg should be placed on the cork of the spike box, allowing a bit of the leg to overhang. The stimulation electrode should be placed on the femur and COXA then the electrodes should be connected to the output of the TENS electrical stimulator. Using the provided LabVIEW program, the onset stimulation delivered to the leg as well as its duration can be controlled. The stimulator should be turned on with the correct corresponding channels by turning the knob clockwise, the current intensity of the impulse increase further when the knob is turned clockwise. A

Cells are rinsed with chilled PBS, scraped into chilled PBS, and then centrifuged at 200 × g for 4 min. Discard the supernatant. The cells are now ready for lysis or storing at -80 ℃ for future use.

where $W_D(H_{i,j}$) is the minimum power consumption of the node $v_i$ to communicate with the farthest node in $H_{i,j}$, and $W_{CC}(H_{i,j}$) is the minimum power consumption of the node $v_i$ to

Step 1: Construct a network diagram for the project. (NOTE: EF for activity H should be 19)

It starts by calculating the shortest path between one node at first, then it checks for the path between two nodes, and so on proceeds in each iteration. I have put the outer loop as V-1, where V is the total number of vertices that is present in the network. In our case, V=6. Therefore, there must be V-1, which is 5 iterations to obtain the optimal shortest path to each of the node from the source node.

In this routing protocol, every node maintains a routing table which has got entries of all the possible destination nodes and the number of hops to each of

When the traffic intensity between the nodes is large then this topology is preferable. In this topology, a certain proportion of nodes have multiple paths to another destination node. Each of the traditional network topologies (Bus, Ring, Star and tree network topologies) had only single path from message source to message destination. Since Mesh Network topology provides multiple paths from source to destination so that greatly reduces the probability of single point network failure. The advantage of mesh network over other networks is that source node determines the best suitable route from source to destination based on factors such as connectivity, speed and pending node activities. Mesh topology is not cost effective, this proves to be a major disadvantage for setting up the network. Another disadvantage of this type of network is the need of a routing algorithm by each node for path computation. When each node in the network is directly connected to every other node then it is called a full mesh. This type of network topology works best with small number of nodes in the network. When some nodes in the network are indirectly connected to other nodes in the network then it is called partial mesh. Figure 1 provides an example of both partial and full mesh

The nodes of bus topology are replaced with standalone star topology networks. This results in both disadvantages of bus topology and advantages of star topology as well. For example, if the connection between two groups of networks is broken down due to cutting of the connection on the central linear core, then those two groups cannot communicate, much like nodes of a bus topology. However, the star topology nodes will effectively communicate with each other. This structure is arranged in a hierarchical form and any intermediate node can have any number of the child nodes.

This algorithms segment the all nodes into clusters of unequal size, and clusters closer to the sink have littler sizes than those more wireless far from the sink. Therefore CHs nearer to the sink can preserved some vitality for the inter cluster data sending. Vitality devoured by cluster heads per round in EEUC much lower than that of LEACH standard yet like HEED protocol.

Datacenter Ethernet: Data center Ethernet has got no limit of distance, it has millions of mac addresses available. This follows rapid spanning tree mechanism and the path for traffic is engineered. Service is provided by a service level agreement

The data transmission is simple and travels in a single direction. There is no data collision. Extra computes can be added with little effect on the performance. Each node connects to two other nodes, making one on going pathway for signals through every single node. Data goes from node to node, with every node handling all the packet.

To the obtained spanning tree from above algorithm we add two types of edges so that we can get a bi-connected graph. The bi-connected graph has a significance that if any of the edge becomes down then also the network will be connected via another edge. This gives us assurance of always up time for a network. This means in case of link failure alternate link will always be present to ensure the network connectivity.

Our algorithm performs at each iteration, a basic change in the network by rerouting the traffic to the destination from the given source by finding an alternate path thereby reducing the load on the common link. As a result a single entry change in the routing table is performed, which is very important for the stability of the network.
