Abstract

A method for connecting, by a central control unit (CCU), a booting switch to a network. The network includes switches controlled by the CCU using control data packets that are transmitted via communications paths in the network. User packets are transmitted through the network using the same communications paths. A switch uses forwarding rules stored in a pipeline to forward packets in the network. A local port in each switch provides access to the pipeline. The paths in the network for the control data packets are established by storing forwarding rules configured by the CCU in the pipelines of the switches. At least one switch contains a connecting port via which the booting switch is connected to the network. The forwarding rules in the booting switch are stored by the CCU using a temporary path, which contains the existing path and a connecting path.
