This paper presents SH (Simple Host), a new and relatively simple method to deal with bandwidth brokering within a loss-less and source routed network, where a percentage of the traf{fi}c can be regarded as background noise. It achieves this by categorizing two types of {fl}ows within a network and provides end-to-endbandwidth brokering for one while accepting that the other simply consumes a limited and de terminate amount of bandwidth. To exemplify our proposal we detail how it could be applied to the recently standard ized Advanced Switching speci{fi}cation.
