Problems solved by technology

[0014] This approach also has a big disadvantage: it is not always clear in advance whether a location is trustworthy, which can seriously reduce the number of locations an agent is allowed to migrate
This can greatly limit the usefulness of a proxy environment

Embodiment Construction

[0037] Figure 1 has been explained in the introductory part of this description.

[0038] Figure 2 shows a typical wireless computing landscape. Several mobile devices 201a, 201b are connected to base stations 204a, 204b over wireless network links. They utilize different wireless network equipment. The base stations are interconnected over a network (eg, the Internet) and to web servers 206a, 206b.

[0039] Figure 3 shows the relationship between the trust center 301, the proxy location 102a and the indexing service. The trust center generates a trust token and sends it to the proxy location. The location can then declare its trustworthiness using the issued trustmark. Agents wanting to migrate can request trust tokens from several locations (target agent location, trust center, index, or others). The verification may be performed by an agent or an agent system.

[0040] A site may obtain trust tokens from various trust centers. Trust tokens can also be made public by ...

Abstract

A technique for managing the migration of mobile agents to nodes of a communication network is proposed. The trustworthiness of at least one node (102b) of the network is checked (301). In case the trustworthiness exceeds a pre-set trust threshold, a trust token for the checked node (102b) is generated (306) and the trust token is stored (303) in the network. In advance to a migration of a mobile agent (104a) to a node of the network it is verified (108, 109) if a valid trust token is existing for the corresponding node (102b). The migration of the mobile agent (104a) is restricted (107) to nodes having a valid trust token.

Description

technical field [0001] The invention relates to a communication network, a method for managing a communication network and a method for managing migration of a mobile agent to a communication network node. Background technique [0002] The invention has its application in the field of communication networks and is preferably applied in the field of mobile computing, wireless communication, mobile multimedia middleware and so-called mobile agents. A particular application is to control (manage) the migration of so-called mobile agents between locations in the network. [0003] Communication involves providing networking services to users over (eg wireless) networks. A so-called mobile agent is a new computing concept capable of transferring an execution segment of a piece of software (code) from one node to another in a computer network. An example of a mobile code system is a Java applet loaded on the Internet in a web browser system. [0004] The concept of mobile agents...
