11. As the result in problem we can infer that the shortest path between u and z is uvxz. ((1+2)%+1%+3%) (a) With traditional routing algorithm, can the network operator split u-to-z traffic along uvxz and utyz for load balancing? Why? (b) With traditional routing algorithm, can the network operator route u-to z traffic along uvxz but to-z traffic along vyz to avoid congestion? (c) Why Software defined networking (SDN) makes network routing more flexible
