System Name: AMETAS
Current Version: 1.0
Organization: Johann Wolfgang Goethe-Universität, VSB
Entry status: authoritative
Supported platforms:
All platforms supporting Java JDK 1.1
Supported languages:
Java 1.1
Implemented standards: none
Type of migration:
weak
How many threads or processes are possible per agent? one
Local communication mechanisms and format of data:
Mailbox system with asynchronous message passing; messages are instances of a message class; agents may be notified on incoming messages or other events
Global communication mechanisms:
Messages may be sent to the mailbox system of another place; agents may deliver messages.
How the communication partner can be addressed:
Communication partners have unique IDs and belong to a group. Messages may be directly addressed or be sent to a group (unicast, multicast, broadcast)
Resource access control mechanism:
configurable policies
Agent tracking:
none
Directory of services:
Local trading
Type of code migration:
All classes as a whole from sending host
Other special features:
* Usage of encryption / signatures / roles / policies for agents
* Strict autonomy (non-exposure of fields and methods, purely asynchronous communication by means of a common message exchange system)
* Event management
* Integration of users and external entities by adapters and services
* Agent type system (work in progress)
* KQML
* Hierarchical place naming system (similar to DNS)
* Temporary and permanent places
Availability:
binary (without security facilities)
License terms:
