Abstract:
1. A method for changing configuration of a network interconnect having routers connected via links, the network interconnect connecting nodes that are not part of the network interconnect, the network interconnect for routing packets that are sent from source nodes and injected into the network interconnect for delivery to destination nodes, comprising: receiving an indication of a change to the configuration of the network interconnect; directing the network interconnect to enter a quiescent state in which the injecting of request packets sent from nodes into the network interconnect is suppressed while the injecting of response packets sent from nodes into the network interconnect is allowed and already-injected request packets are allowed to continue through the network interconnect, wherein a response packet is sent from a node in response to a request packet; and after the network interconnect enters the quiescent state,
