Network Management
NET-SNMP
Diferent tools for SNMP for instance:
-
a extensible agent
-
a SNMP library for building SNMP access modules
-
tools for generating and collecting traps

One of the best sources for telecom news.
We have during the last 5 years worked mostly within the area of Tele Network management (TNM) and have through our work gained a large experience both as systems architect and as software developer. We have primarily worked with the development of management software for the Synchron Digital Hierarchy (SDH) and IP networks. We have especially gained a large experience within protection mechanisms such as Multiplex Section - Shared Protection Rings (MS-SPRing), where we have participated in a complete design of a monitoring and provisioning application.
TeMIP
TeMIP is a Network Management platform developed by Digital, then by Compaq and now by HP. We have worked on different projects by different software vendors making access modules, alarm filtering, alarm correlation, root cause analysis, what-if analysis and alarm state propagation. We have a great deal of experience from working with the implementation of the TeMIP Service Monitor.
SNMP
Simple Network Management Protocol (SNMP). But although it was thought of as being simple as it was invented, it is now commonly used for monitoring almost all kind of networked equipment from printers, routers, computers and applications as web application servers and databases. SNMP exists today in more versions where V3 has builtin support for encryption. SNMP is used to control the probably hottest protocol as of today: MPLS. We have in EMERCOS been working with SNMP for collecting traps and alarms and have implemented SNMP over other protocols than UDP as it was designed to. We have good experiences with the work with NET-SNMP (also known as UCD-SNMP).
Ethernet
In the early days of the history of internet we in EMERCOS worked with implementing ethernet hardware cards for industrial embeddes OS-9 based computers; writing device drivers and porting the tcp/ip protocol stack. In those days Ethernet (IEEE802.3) was not considered as the hightech protocol because of its stocastic network delay caused by the CSMA/CD protocol. In the scientific circles TokenRing was considered to be the best choice.
However, ethernet has survived and is today the most widespread network protocol. And the speed has gone up - today we speak 10 gigabit-ethernet, MPLS over ethernet, ethernet over MPLS. Ethernet is used as the carrier protocol in WANs. Who would have imagined that 10 years ago!?
