IP MIB for IP Fast-Reroute draft-ietf-rtgwg-ipfrr-ip-mib-03 This draft defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects relevant for IP routes using IP Fast-Reroute [RFC5714

AgentAPI: an API for the development of managed agents

Managed agents, namely SNMP agents, costs too much to develop, test and maintain. Although assuming simplicity since its origins, the SNMP model has several intrinsic aspects that make the development of management applications a complex task. However, there are tools available which intend to simplify this process by generating automatic code based on the management information definition. Unfortunately, these tools are usually complicated to use and require a strong background of programming experience and network management knowledge. This paper describes an API for managed agent development which also provides multiprotocol capabilities. Without changing the code, the resulting agent can be managed by SNMP, web browsers, wap browsers, CORBA or any other access method either simultaneously or individually

Performance Analysis of SNMP in OLSRv2-routed MANETs

Mobile Ad Hoc NETworks (MANETs) are generally thought of as infrastructure-less and largely "un-managed", capable of accommodating highly dynamic network topologies. Yet, while the network may be un-managed, monitoring performance and setting configuration parameters post-deployment, remains important in order to ensure proper ''tuning'' and maintenance of a MANET. While SNMP is sometimes considered too ''heavy'' for MANETs -- a too chatty a protocol with too large protocol messages -- it remains the predominant management and monitoring protocol in the Internet, and many implementations exist. This \articleformat analyzes SNMP in an OLSRv2-routed MANET, with the purpose of investigating performance metrics, such as delivery ratio, delay, management overhead, collisions and performance monitoring accuracy. In order to address concerns both regarding SNMP being "heavy", as well as regarding the accuracy of performance reports obtained via SNMP polling in MANETs, where path delays can be highly variable, the utility of performance reporting proxies, i.e. the REPORT-MIB, is studied. The obtained results show that a significant benefit can be obtained by so deploying performance reporting proxies in an SNMP managed MANET. The investigations are supported by way of network simulations (NS2).Lorsquon parle de réseaux mobiles ad-hoc (MANETs), on pense généralement à des réseaux sans infrastructure et à des déploiements en réseaux largement non-gérés, pouvant s'adapter à des topologies de réseau très changeantes. Néanmoins, bien que l'infrastructure du réseau est de nature non-gérée, la surveillance des performances du réseau et le choix des paramètres de configuration une fois le réseau déployé demeurent primordiaux pour la maintenance et le réglage fin d'un réseau MANET. Alors que SNMP est parfois considéré trop "lourd" pour des MANETs, il demeure le protocole prédominant de management et monitorage d'Internet, et beaucoup implémentations du protocole existent. Ce rapport analyse SNMP dans des MANETs basés sur OLSRv2, avec l'intention de déterminer des métriques de performance, comme le taux de remise, délai, overhead et collisions dans le simulateur de réseaux NS2
