Current network management needs an end‐to‐end overview of various flows rather than the information that is purely local to the individual devices. The typical manager‐centric polling approach, however, is not suitable to understand network‐wide behavior of a large‐scale Internet. In this paper, we propose a new management information base (MIB) approach called Service Monitoring MIB (SM MIB). The MIB provides a network manager with dynamic end‐to‐end management information by utilizing special packets. The special packet is an Internet control message protocol (ICMP) application that is sent to a remote network element to monitor Internet services. The SM MIB makes an end‐to‐end management feasible while it reduces management‐related traffic and manager‐to‐manager interactions. Real examples show that the proposed SM MIB is useful for end‐to‐end QoS monitoring. We discuss the accuracy of the obtained data as well as the monitoring overhead.
