Revision with unchanged content. Network management is essential for the
operation and supervision of me-dium to large computer networks. The
Simple Network Management Protocol (SNMP) is the standard protocol for
network management in the Internet. Or-di-nary SNMP agents are mostly
monolithic, run in the user-space and often poll information from the OS
kernel. This book examines to what extent the IETF standard sub-agent
protocol AgentX is suitable for the management of UNIX/Linux kernel
components. For this purpose, AgentX sub-agents have been implemented
inside the kernel subsystem they manage. They use the AgentX protocol
for communication with a master agent in user-space. With this approach,
kernel subsystems can be managed in an efficient and com-pre-hen-sive
way. The author describes the general design of this new in-kernel
manage-ment architecture and its interface to the user-space. As an
example, two kernel sub-systems, namely the network interfaces and Linux
Netfilter, are implemented as MIB modules and explained. This book is
intended for software developers of network and system ma-nage-ment
solutions as well as researchers in this area.
