This online course provides an overview of the main features offered by Nagios. It first introduces the key concepts (coloured area concept, shadowed states, service checks) of Nagios and describes the underlying functional architecture. It then explains how Nagios determines status information about hosts and services using periodic normal and retry checks. It also shows how this information can be sent to administrative contacts based on alerts using an advanced notification system, or can be directly accessed through the web interface. In addition, it details the configuration parameters and the execution of checks within Nagios. A new complementary course on advanced configuration with Nagios is available on this link: https://www.youtube.com/watch?v=blZFouA2mdQ An online exercice is provided on http://goo.gl/forms/fUMKhzIzsp to evaluate your knowledge on the key concepts and features addressed in these two online courses, through a series of 30 questions. It also permits to progressively build small configuration files that can then be experimented by followers on their own infrastructure in 7 detailed steps with an ubuntu distribution.

The course entitled „Wireless Sensor Networks integrated in Internet of Things“ is three-folded: (1) Definition on basic terms, (2) introduction to wireless sensor networks, and (3) application area. The first part motivated why a basic understanding of wireless sensor networks is required today and where they are already deployed (e.g., Internet of Things, Cyber- Physical Systems). The second part of the lecture presents the basics of wireless sensor networks raising from structure, involved components, and their hardware characteristic. Followed by requirements (e.g., scalability, quality of service) the user has to be aware of when deploying a wireless sensor network and the corresponding design principles (e.g., network organization). With this basic knowledge the user is able to deploy such a network. In order to give the audience an impression where wireless sensor networks are already deployed, part three of the lecture focus on this. The application area is manifold and selected ones are presented, such as structural health and habitat monitoring, health applications, logistic and military scenarios, and automation.

This video introduces the standard Management Information Base: MIB-II, as defined in RFC 1213. After an introduction it discusses the status of the MIB-II, the original design goals, the basic structure of the MIB-II, the relationship to the TCP/IP layers, and the various groups (system, IF, AT, IP, ICMP, TCP, UDP, EGP, Transmission and SNMP). Since the MIB-II is based upon the initial version of the “Structure and identification of Management Information” (SMIv1 - RFC1155), it has later been updated to the SMIv2 (RFC2578) and split into various smaller MIB modules, such as the IF and IP MIBs. Although this video discusses the initial MIB-II, it should still provide a good overview of the most frequently used managed objects.

Network Function Virtualization (NFV) focuses on virtualization of software-based network func- tions. Service Function Chaining (SFC) consists of building services using virtual network functions (VNFs). In this video, the main technologies and enablers for NFV are detailed. It is highlighted why network operators and service providers are eager to adopt the above principles. We believe that efficient management of software-defined virtualized telecommunication systems and data centers will be of key importance in the future. Some key challenges for future research are addressed as well in this video. Target audience: people with network management knowledge, but not familiar with virtualization of network functions.

David Harrington works for Comcast and has worked on Cabletron, Enterasys, and Huawei. He has been active in IETF and NMRG since the early 1990s. He was active in the MIB Doctors, Security, Operations, SIRS, and DILBERT directorates, and Technical Advisor to sipclf, capwap, and midcom working groups. He was MIB Technnical Advisor for IEEE 802.1, and coordinated the transfer of responsibility for BRIDGE MIB modules from IETF to IEEE. He chaired SNMPv3, SNMPCONF, SYSLOG, BRIDGE, and NETMOD working groups. He has authored or actively contributed to more than 65 RFCs, most related to securing network management. The interview starts with David talking about his background in the IETF. He gives some reasons why SNMPv2 failed and the deadlock the SNMP community ended up before developing SNMPv3. He discusses the divide and conquer approach of the SNMPv3 architecture, allowing the standardization process to move forward, based on the idea of modules, which can be plugged into SNMPv3 without interfering with other modules. He then provides some insight why it was decided to have the access control subsystem being part of the SNMP engine, instead of the applications. He explains why SNMP is better for monitoring than for configuring, and discusses the raise and fall of COPS-PR. Finally he gives the advantages of using NETCONF for configuration, instead of to SNMP. The interview was recorded in July 2013 at the IETF87 Berlin meeting.

Very recently, leading equipment providers in the network infrastructure market launched the first software-enabled appliances that support network virtualization capabilities. The main advantage of Software Defined Networking (SDN) is that network control is separated from the forwarding plane and allows for a flexible management of the network resources. Network virtualization (NV) brings virtualization concepts to the network, similar to cloud computing, which was enabled by virtualization of servers. In this video, the main technologies and enablers for this promising paradigm are detailed, and pointers to more detailed information are provided. Target audience: people with network management knowledge, but not familiar with man- agement of virtualized resources.

In this talk we stress the importance of publishing your research results at the right venues. First we identify the workshops, conferences, magazines and journals in the area of network and systems management, but also in the broader networking area. We will discuss the quality of some of our conferences and journals, as perceived by experts in our field, as well as people outside our area. In addition we present acceptance rates, acceptance procedures, conference and journal rankings, as well as impact factors. Although some Ph.D. students may believe that a main goal is to publish as many papers as possible, this talk will stress that there are other important metrics, such as some key venues and the number of citations. We will discuss the pros and cons of the H-index, a metric that is currently quite popular for judging quality of people as well as conferences, but has several limitations. The talk concludes with explaining the importance of publishing in journals indexed in Thomson’s Science Citation Index (SCI), or alternatives like Scopus. It also explains CPP, JCS and FCS factors.
