Forensic Significance of Certain Types of Computer Networks

Stating the great forensic potential of computer networks, the author differentiates computer networks into 6 types (in terms of functionality and level of service): personal (BAN), personal (PAN), local (LAN), campus (CAN), urban (MAN) and global networks (WAN). It seems that the BAN and PAN level networks can be conditionally combined into a single group — personal networks (some of its devices can be part of both one and the other network or be elements of both at the same time). It is logical to accumulate LAN and CAN networks into a group — collective networks, and megapolis (MAN) and global (WAN) networks into a group — multiuser networks. In the paper, the author focuses on collective and multiuser networks. At the same time, it is also indicated that there is a need to allocate a national level of computer networks. The author examines the criminalistically significant fundamentals of the functioning of the networks under consideration. The paper determines the specifics of the work and the main tasks of the researcher in the study of networks of various levels. It is stated that relevant information can be extracted from almost any type of network. Awareness of the type, hierarchy and level of network coverage will help optimize the investigation by increasing the speed of identifying the provider, the administrator and obtaining information about the network user from him. Based on the results of the study of network specifics, general recommendations for working with any type of network are offered.

Dynamic QoS: Automatically Modifying QoS Queue's Maximum Bandwidth Rate-Limit of Network Devices for Network Improvement

The heterogeneous data traffic of today's network is a huge challenge to existing best-effort network technology, particularly in the context of large Ethernet, which handles hundreds to thousands of users. The existing conventional best-effort network technology is no longer efficient to handle the diversity of traffic types in the network and requires network management equipment such as Quality of Service (QOS). Usually, QOS is implemented on the gateway router. However, for better network performance and management, to guarantee high priority for sensitive traffic like video conferencing, Voice over Internet Protocol (VoIP), and streaming media within an internal network, it is nice to have QoS implemented on each router in the LAN network, starting from the access router to the gateway router. This paper is to demonstrate the effectiveness of the proposed dynamic QoS that has been developed and deployed in the LAN, purposely to provide adequate bandwidth for sensitive traffic when the network utilization is high and congested, by automatically modifying the QoS Queue's Maximum Bandwidth Rate-Limit of the best-effort traffic queue of the related router. The performance of the proposed developed dynamic QoS was evaluated via a comparison study before and after the dynamic QoS was presented in the network simulation environment that was built using Mininet. Results from the testing show that the developed dynamic QoS can improve the network's performance by automatically giving the appropriate bandwidth for sensitive traffic on the fly while needed/on demand.
