Tracing Network Packets Through Logical and Physical Networks |
摘要 |
Some embodiments provide a method for a first network controller that manages a set of logical forwarding elements implemented in several managed forwarding elements. The method receives a request to trace a specified packet having a particular source on a logical forwarding element. The method generates the packet according to the packet specification. The generated packet includes an indicator that the packet is for a trace operation. The method sends the packet to a second network controller that manages a managed forwarding element associated with the particular source. The method receives a first set of messages regarding operations performed on the packet from a set of network controllers that receives a second set of messages regarding operations performed on the packet from a set of managed forwarding elements that process the packet. |
