The boson tagging at ILC, based on di-jets masses reconstruction, has leaded to consider the reconstruction of multijet events as a major goal for the detector on this machine. I will describe the technique called Particle Flow Algorithm (PFA) which optimise the multijet reconstruction .The main direction of the R&D studying calorimetry optimised for PFA, is concentrating on fine granularity calorimeters with a high degree of longitudinal segmentation. The CALICE collaboration works on the technical feasibility of such detector. Several technologies for electromagnetic and hadronic calorimeters are pursued with prototypes in test beam and new generation prototypes , very close to ILC like detector are under development with a very high degree of integration.
