A protocol is a collection of specifications or rules for data packets that enable information to be sent over the network. Network protocols are designed for network communication. In order to understand the different protocols available and their efficiencies, lets first look at the Open Systems Interconnection (OSI) reference model. This is the standard model …
Monitoring Network Activity with Network Monitor The tool which you can utilize to both monitor and log network activity as it occurs on the network is the Network Monitor. You can use the information obtained from Network Monitor to optimize network traffic as well. Network Monitor stems directly from the Windows NT Network Monitor. Network …

IPv6 stands for Internet Protocol version 6. IPv6 is the latest version of the network-layer protocol for packet-switched networks. The version that is generally used is IPv4. One of the reasons for the upgrade to IPv6 is that it allows greater space and flexibility in assigning IP addresses. For instance, IPv4 is based on a …
While encryption can be a robust security technology, users have to implement a public key infrastructure (PKI) to make it beneficial and trusted within an organization. The Windows 2000 and Windows Server 2003 PKI implementation resides in Certificate Services. A public key infrastructure is the collection of technology, protocols, services, standards, and policies that control …
Department of Defense Network (DoD) Network Model Introduction Back in 1960, systems were primarily made up of mainframe computers, and were typically owned by fairly large companies and government institutions. Because mainframe computers run different proprietary software, and due to mainframes not being able to communicate between each other, special code (interface) had to be …
When routers need to forward packets, they interpret the packets’ addresses then use the information in the routing tables to pass the packet on. Data packets contain both source and destination addresses in their packet headers. This is the information that is used when routing decisions need to be made. The destination address is compared …
