A method for providing a differentiation in terms of quality of service (QoS) for multiple tenants in a network, by a networking device receives a data packet from a transmitting tenant, and the networking device identifies the tenant and a priority class of the received packet. The networking device then determines one or more color markers to apply to the received packet according to the sending tenant and the priority to be associated with the packet. The networking device then transmits or does not transmit the packet onwards depending on one or more color markers applied to the packet.

A method for rerouting traffic by a switch in a software defined networking (SDN) arrangement comprises an additional switch, multiple routing paths between the original switch and the additional switch being preconfigured by a SDN controller. The original switch collects network statistics by transmitting monitoring packets on each of the multiple routing paths and then calculating a round-trip time (RTT) value for each path on the return of the monitoring packets to the additional switch, the two switches functioning together as local controllers. After collection of network statistics from all the multiple routing paths, the original switch selects the routing path with the smallest RTT value and reroutes traffic accordingly.
