Resource: Patton-Fuller Community Hospital Virtual Organization

Based on Patton-Fuller Community Hospital Network, prepare a 1,500 - to 2,500-word paper including the following:
- Identify network system elements (routers, switches, servers and workstations etc) in use. (10 pts)
- Identify network protocols in use within each of the seven OSI layers. (5 pts)
- Research on networks deployed by other health care organizations and recommend additional network elements and protocols that may be used to enhance current network. (5 pts) Hints and clarifications:
1 With regard to network system elements, please describe what elements are used and where. Also briefly explain why the elements are used when appropriate (e.g, “The VPN router serves as a VPN concentrator/server and provides VPN access to remote users.”).
2 For network protocols, identify which of following core protocols are in use and expand around them:
a. Layer 1 and 2: what network interfaces are involved? Example of network interfaces are Ethernet, FDDI, ATM, Frame-Relay, T1 etc.
b. Layer 3: It’s important to first determine which network protocol suite(s) is/are used in the network(example of network protocol suites are TCP/IP, Appletalk, IPX/SPX etc). The core protocol for layer 3 is then IP for TCP/IP, DDP for Appletalk, IPX for IPX/SPX. Other important protocols in this layer include various routing protocols and network address to physcial address mapping protocols (e.g, ARP in TCP/IP).

Osi Model and Cisco Systems Inc. Essay

point-to-point links. Recall a physical point-to-point topology connects two nodes directly. In a point-to-point WAN architecture, layer two frames are placed on the communications medium at the source and removed at the destination. This architecture allows the data link MAC protocols to be very simple since frames can only travel between the two nodes. This simplicity allows the layer two switching to be optimized and performed in hardware achieving an efficient low latency communications channel. Lastly…

Osi Model and Network Essay

Communication Protocols In the network industry, communication protocols play a vital role for masking communication a possibility. Not everyone uses the same hardware or software platforms, but all need to be able to communicate no matter the system. That is where protocols come into play. The ability to code and decode protocols are built into the computers operating system. There are hundereds of different types of protocols. One that users see everyday is Hyper Text Transfer Protocol (HTTP). The…
