Automatic Dynamic Resource Management architecture in tactical network environments

Abstract

Abstract-Automatic Dynamic Resource Management (AutoDRM) is a method to efficiently manage shared resources in the tactical network environments without human operator intervention. The AutoDRM architecture is developed as an attempt to resolve the resource contention issues and to improve the quality of service in the tactical network environments. The information herein describes the key components of the AutoDRM architecture. An experimental end-to-end network prototype test bed was also developed to host the AutoDRM system. Experimental results demonstrate improved network performance when AutoDRM is deployed.

DDAM: Dynamic network condition detection and communication adaptation in Tactical Edge Networks

“…Two systems similar to DDAM are described in [4] and [5], the first implementing its own monitoring system, the second using SNMP packets. In [4], the authors suggest to deploy the passive monitoring system close to the COMSEC gateway, a decision that we also made as shown in Fig.…”

“…The performance monitor of the solution presented in [5] instead uses Network Management Station (NMS), which in turn uses SNMP to retrieve network statistics. Thus, the solution is affected by the aforementioned SNMP problems.…”

“…The solution presented in [5] also implements an interesting approach to the network-resource allocation problem where a centralized component is responsible for allocating network resources, whereas we envision that the results provided by NSup will be shared with other components, which will in turn adapt to the network conditions in an independent way.…”

“…Significant prior work has focused on how to use monitored statistics such as congestion level, packet loss rate, and available path capacity in order to estimate metrics that affect performance of applications. However, proposed solutions generally do not address the problem of determining which underlying communication technologies are being used, and assume to already have notions about it, or ignore the problem altogether [4] [5]. Each of the many communication technologies deployed in TENs has specific and peculiar characteristics that network administration systems and adaptive applications cannot ignore if their purpose is to use networks as efficiently as possible.…”
