Embodiment 1
[0049] This embodiment provides a bandwidth scheduling method for two fixed paths in a high-performance network oriented to big data, including the following steps:
[0050] Step 1, establish the topology graph G(V,E) of the high-performance network (HPN):
[0051] G=(V,E)
[0052] Among them, V represents the node set in the high-performance network, V=(v 0 ,v 1 ,...,v n-1 ), n≥1; E represents the link set in the high-performance network;
[0053] The available bandwidth of the link changes in each time period, and the time-bandwidth triplet (t l [i],t l [i+1],b l [i]);
[0054] Among them, t l [i] indicates the i-th moment of the link l, t l [i+1] indicates the i+1th moment of link l, (t l [i],t l [i+1]) represents the i-th time slot of link l, b l [i] indicates the bandwidth value of the i-th time slot of link l, i=0,1,2...T l -1,T l is the total number of time slots of link l, T l ≥1;
[0055] The TB tables of all links are synthesized into a total TB (Aggr...
