Description / Abstract:
WBEM Discovery using the Service Location Protocol (SLP)
This specification describes an efficient method for WBEM
Clients to discover WBEM Servers and WBEM Server capabilities.
The objectives of this specification are to:
• provide a mechanism that allows WBEM Clients to discover WBEM
Servers
• use existing standards and protocols for rapid development and
deployment
• provide a mechanism that scales from small environments to
enterprise environments
• provide WBEM Clients sufficient information in the
advertisement to determine the WBEM Servers to communicate with
• scope the level of advertisement to avoid security holes
The Service Location Protocol provides a flexible and scalable
framework for providing clients, represented by User Agents, with
access to information about the existence, location, and
configuration of services, represented by Service Agents.
Traditionally, clients have had to know the name and access
method of services. The SLP eliminates the need for a client to
know the name and access point of services. With SLP the client
supplies a request for the desired type of service. The client
receives information regarding the requested services.
The SLP uses Directory Agents that offer a centralized
repository for advertised services. This allows the SLP to scale
from very small to very large environments.
WBEM Servers acting as Service Agents advertise their services.
WBEM Clients acting as User Agents query for the WBEM Server(s). A
Directory Agent may be deployed in environments where there are
many User and Service Agents.
