Abstract: Interconnect systems and method of operating such are disclosed. A plurality of nodes coupled via a packet transport path form an interconnect and the nodes provide ingress points to the interconnect for a plurality of packet sources. A central controller holds permitted rate indications for each of the plurality of packet sources, in accordance with which each packet source sends packets via the interconnect. The nodes each respond to packet collision event at that node by sending a collision report to the central controller. In response the central controller, in respect of a collision pair of packet sources associated with the packet collision, decreases the permitted rate indication corresponding to a packet source of the collision pair of packet sources which currently has the higher permitted rate indication. Periodically the permitted rate indications of all of the packet sources are increased, subject to a maximum permitted rate indication for each.
