resources the present architecture foresees a scenario where 5 to 10 slices share the overall network resources such limitation is mandated by the computing and storage constraints that characterized currently used wireless multi hop networking devices but may be enlarged in the future traffic shaping is performed at each node in order to limit the amount of network resources used by each sliver in this simplified setup the resources that each sliver can exploit are upper bounded by a fixed threshold derived from the relative performance goal given during the planning phase as a result slice a u201c sees u201d an 800 kb s bidirectional link between node 1 and node 2 while the available bandwidth between node 2 and node 3 is 1600 kb s in this setup some bandwidth is voluntary left unused however scenarios where a sliver can have full access to all the available bandwidth are also supported fig2 sketches a possible use case where a production slice exploiting a stable version of a routing protocol is running in parallel with an experimental slice where novel routing strategies are being tested in this scenario the link broker is used to expose two different connectivity graphs to the two available network slices production and experimental on the other hand the bandwidth partitioner is used to redistribute the available link bandwidth among the competing slices i e 80 of the overall network capacity to the production slice and 20 of the overall network capacity to the experimental slice please note that a minimum bandwidth e g 1 mb s can also be allocated to the production slice hereafter the present invention node 39 s architecture see fig5 is described in.
