1. A method for routing data applying service level agreement in a link aggregation group, the method comprising:
receiving by a network switch, a performance measurement packet;
splitting the performance measurement packet into child performance measurement packets;
routing each of the child performance measurement packets through separate constituent links of a link aggregation group;
determining performance parameters of each of the separate constituent links based on each of the child performance measurement data packets;
in response to determining performance parameters of each of the separate constituent links, determining whether one or more of the constituents satisfies a service level agreement performance parameter; and
in response to determining whether one or more of the constituent links satisfies the service level agreement performance parameter, routing a data packet requiring the service level agreement performance parameter through one of the one or more constituents determined to satisfy the service level agreement performance parameter.
