10. A method comprising:
querying from at least one further processing unit, per a further processing unit, information relating to chaining possibilities of logical processing units in a pipeline abstraction instantiated, said information queried comprising at least a number of ports and per a port address information and information on a direction of the port;
configuring, using said information, per a logical processing unit to be chained, per an endpoint representing a port in the logical processing unit, at least a type of the endpoint, and address information whereto connect the endpoint, wherein the type of the endpoint is either a host port type or a logical processing unit type; and
offloading from at least one central processing units one or more functions to be performed by one or more of the at least one further processing unit by interacting with the one or more logical processing units via endpoints of the host port type and by interacting between logical processing units via endpoints of the logical processing unit port type, the interaction using the address information.
