Improving SLP efficiency and extendability by using global attributes and preference filters

The paper presents two new mechanisms, global attributes and preference filters, that improve the efficiency and extendability of the service location protocol (SLP). Global attributes describe common service properties, which can be used to perform queries across different service types, and can be standardized for service management. Preference filters facilitate processing of search results, such as finding the best match, in SLP servers. They can reduce the amount of data transferred to the client, and better support thin clients with limited resources and capabilities.
