A network topology algorithm based on SNMP was put forward and implemented. This algorithm could confirm the connection between ports and improve the efficiency of discovery through combining the topology discovery of the network layer and the link layer. It could solve the problem of subnet information redundancy and incomplete information of address forwarding table during the discovery. The experimental...
To manage Ethernet networks efficiently, detailed and accurate knowledge of their topology is needed, like network partition, performance prediction are based on network topology. In this paper, we proposed an algorithm to discover physical layout topology structure of Ethernet networks with incomplete address forwarding table information. This algorithm can handle both layer-2 switches with VLAN...
Optical networks are well known for offering highrate bandwidth by sending data over light wavelengths. Such optical networks are composed of fiber optics, amplifiers, Reconfigurable Optical Add-Drop Multiplexers (ROADMs), etc. Nowadays, we wish to manage and monitor that type of network especially the ROADMs -- both flexibly and intelligently by integrating Software Defined Networking (SDN) into...
Installed sound applications typically involve a large number of audio processors, amplifiers and speaker systems spread across the venue. They could be spatially distributed at the venue across different rack rooms and floors. These systems are commissioned and configured by sound engineers using software application(s). This is essentially a one-time activity, following which, the audio systems...
The single chip microcontroller units (MCU) are widely applied in various embedded systems combined with different function type of sensors, robots, hybrid vehicle, or communication interfaces to control circuits. Usually single chip MCU system is triggered via the input voltage to affect the internal program logic, and then, the output state is changed. Simple Network Management Protocol (SNMP) is...
The enlargement of the current enterprise network scale makes the conflict between application systems and network devices inevitable. To address this issue, this paper proposed a verification method of network reach ability based on topology path. Our approach extracts communication need of application systems through formalization method, so the problem of whether the communication need will be...
