Service deployment device, service execution device, and ad-hoc network

A deployment device for deploying a service composed of multiple microservices in an ad-hoc network with multiple devices which are communicatively connected to one another, the deployment device comprising:

• a controller, configured to:
• monitor a status of the ad-hoc network by collecting:
• a topology of the ad-hoc network, current resources of the multiple devices of the ad-hoc network, changing behavior of the ad-hoc network, a data transmission delay between a respective data source of a plurality of data sources and microservices that need data from the respective data source, and a relation between the microservices that compose a service;
• create a service tree based on a service map and the status of the ad-hoc network, wherein the service tree defines a service that is composed of multiple microservices where each microservice is allocated based on the relation between the microservices, and wherein the service tree includes an assignment of each of the multiple microservices of a service to a service device of the ad-hoc network and includes a plurality of segments, defined by the microservice relations, linking the multiple microservices to their respective data sources;
• create an entry in a source routing table to transmit one of the multiple microservices to the assigned service device;
• generate a deploy packet for each of the multiple microservices, wherein each deploy packet carries a respective microservice in a payload of the deploy packet and a source routing chain indicating the routing chain of the deploy packet to the assigned service device in a header of the deploy packet, the source routing chain including, for each respective deploy packet, a number of faces derived based on a distance to the assigned service device;
• and
• deploy the deploy packet in the ad-hoc network.
