Internetworking Technology Paper - Essay Example In order to connect the workstations of these employees, switches are terminated on each department. However, there is a possibility that more than one switch is required to cover up all the nodes. As mentioned earlier, star topology is implemented for centralized administration and configuration of the network, the diagram demonstrates Microsoft Active directory that connected with a domain controller. Active directory is an advanced directory service that is a built in feature for Windows server that is utilized for access management for network resources. Moreover, it is a domain based network similar to the Domain Naming System (DNS) (Active directory.2011). Protocols that are used include LDAP and Kerberos for security purposes. The selection of switches is essential, and compatible routers must be considered, as cisco supports active directory in its IOS router (Active directory.2011). Each switch supports gigabit full duplex Ethernet capability that will operate on a CAT 5 100 0 base-t cables. The company does not want interruption in the local area network and it must be available for all times. For this reason, all the switches are powered by PoE (Power over Ethernet) that is a distributed power mechanism on a CAT 5 Ethernet cable (Poe.2011). Likewise, PoE enables a secondary channel for power distribution and continues to provide power to networked devices even if the primary power link goes down. As shown in the Fig 1.1, the blue link shows PoE connectivity between networked devices for ensuring network continuity. Moreover, there are two routers aggregating data channels and configured to backup each other. In case of a primary router failure due to malfunctioning hardware or configuration, secondary router will make itself available up to the task. Furthermore, to ensure redundancy in software infrastructure, primary and secondary domain controllers are installed for load balancing and backup procedures. In addition, for security purposes, Virtual L AN can be configured for distributing data channels associated with highly sensitive data. For addressing security, Fig 1.1, demonstrates a firewall that is installed after the router and in between the Internet to ensure the filtration of inbound and outbound network.

Emergency plan - Thesis Example They might come as a result of: terrorism, strong tornado, a passenger airplane crash, major highway accident and hazardous material release (Dr. K. Qureshi, 2005). If one of these incidents happens, there should be an emergency plan put in place to respond to this call. Generally, this involves the county emergency department in the U.S. Every county has a unit to respond to these calls. These standard operation procedures outline how to manage and respond to incidents that are different than the normal response system (Graham, 2010). These procedures are applicable for EMS incidents involve more than four ALS units to provide assistance and patient care. The main objectives of this units is to minimize human suffering, disabling injuries and most important minimize loss of life (Downey, Andress, & Schultz, 2013). Another objective is to provide integrated and adequate resources required to mobilize teams and units to manage casualties effectively, while maintaining the resources an d capability to respond to other situations within the community (Gordon, 2002). In creation of this plan, the first stage should be establishing of the incident Command System (ICS) (Frykberg, 2002). This organization is to manage resources in response to state objectives and in relation to the incident. Respecting each organizations jurisdiction and command should be a mandate to any team involved (Maurer, 2009). The incident command should consider identifying the Medical Branch with its Medical Branch Director and a Resource Assembly Point (RAP) (Socha, 2002). The Medical Branch Director should ensure safety of the scene for both responders and patients, and also coordinate with other groups to provide additional resources and equipment, establish triage, decontamination, rescue and extraction, treatment and transportation (Risavi, Terrell, Lee, & Holsten, 2013). This process may be
