DISCOVERY OF NETWORK ELEMENTS AND RECONCILIATION (DNER)

Abstract

Designing of an efficient discovery module is a key challenge in a spread out network. It is necessary to keep records of each and every device in network for the company by which it can keep the details about the devices recorded in the network as per the status of presence or failure of that device. Discovery of Network Elements in the network is achieved through two modes of discovery that are through IP Range Specification i.e. Range Based Discovery, Device Based Discovery and Individual Discovery. In Range Based Discovery we have to give the range of IP addresses which are already present in the database, this will discover existing network elements and maintained their information. In Device Based Discovery manufacturer of network element is specified and IP addresses are fetched from the master database depending on the manufacturer and a SNMP request is send to those network elements. In Individual Discovery a single IP address is specified and the discovery of that network element is carried out. Reconciliation module contains two types of discrepancies which are depending upon the types of Discovery carried out as Range Based and Device Based. Discrepancies are nothing but the differences found by comparing the master database and discovered database.
