A method includes a local switch receiving a first set of upstream packets and a first set of local packets, each assigned a first class of service. The local switch inserts, according to a first insertion rate, a local packet between subsets of the first set of upstream packets to obtain an ordered set of first class packets. The local switch also receives a second set of upstream packets and a second set of local packets, each assigned a second class. The local switch inserts, according to a second insertion rate, a local packet between subsets of the second set of upstream packets to obtain an ordered set of second class packets. The method includes for each timeslot, selecting a class, and forwarding a packet from the selected class of service to a downstream switch. The switches are interconnected in a daisy chain topology on a single chip.
