MAC address fields in the 802.11 frame? Which MAC address in this frame corresponds to the wireless host (give the hexadecimal representation of the MAC address for the host)? To the access point? To the first-hop router? What is the IP address of the wireless host sending this TCP segment? What is the destination IP address? Does this destination IP address correspond to the host, access point, first-hop router, or some other network-attached device? Explain. (Hint: review Figure 5.19 in the text if

architectures and distributed systems. These programmable networks call for programmable switches and routers that (using virtualization) can process packets for multiple isolated experimental networks simultaneously. For example, in GENI it is envisaged that a researcher will be allocated a slice of resources across the whole network, consisting of a portion of network links, packet processing elements (e.g. routers) and end-hosts; researchers program their slices to behave as they wish. A slice could extend

2. Network description a. Router The router connects multiple LANs together. It will filter and forward incoming traffic from other LANs to the network. In addition, it will filter and direct outgoing traffic from the internal network systems to the correct LANs. b. Firewall: It will filter all the incoming and outgoing traffic of the network, which means that it will protect the network and the network systems from unauthorized access. It will allow only a certain set of services to pass

T1 lines and a satellite connected overseas. T1 leased lines are used for the Atlanta, Phoenix, New York, and Chicago offices. China connects through a satellite service. A Virtual Private Network (VPN) connects wireless users to their designated department through mobile devices. Routers are used to direct communication between LANs and are needed at each department. Voice over IP (VoIP) has opened possibilities for more interactive communication across WAN networks. VoIP bypasses the need of conventional

Headquarters, Austin, TX For the Austin, TX site, since there are 500 hosts both wired and wireless, I would separate the IP assignments into 2 separate groups: approximately 250/250. To do this I would assign the IP assignments as follows: 192.168.100.1 through 192.168.100.254 for all the wired hosts and 192.168.101.1 through 192.168.101.254 for all wireless hosts. This location will also need a router. The subnet mask for these locations will be 255.255.254.0. Rural Satellite Office, Austin

A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). Ethernet switch devices were commonly used on home networks before home routers became popular; broadband routers integrate Ethernet switches directly into the unit as one of their many functions. High-performance network switches are still widely used in corporate networks and data centers. Advantages Switches have increased available network bandwidth. There is reduced workload

shared by at least four members. Hardware purchasing Routers and modems Checking on the above connection, router is actually the most significant device. This is because it enables the four individual (computers, B, C, D to share internet connection and also to route network traffic over Internet. On the other hand, there is modem, there is modem in the above home network and it acts as the source of router because routers gets internet from it and supply it to the rest of shareholders
