Abstract: Example embodiments relate to providing efficient routing in software defined networks. In example embodiments, an indirect group table includes a first group entry that is associated with a first route tree in a software defined network. A failure is detected in the first route tree during a data transmission, and a notification of the failure is sent to a remote controller device, where the remote controller device identifies a second route tree that does not include the failure. After the remote controller device updates the first group entry to be associated with the second route tree, the data transmission is performed using the second route tree.

Abstract: Examples relate to dynamic allocation of flow table capacity. In some examples, packet-in events of a networking device are monitored and processed to create active flow entries in a flow table. After detecting that the packet-in events at the networking device exceed an overload threshold, the active allocation of the flow table is increased. At this stage, a backup flow is removed from the flow table based on the active allocation.

Abstract: A method may include determining whether a host destination address of a packet received at a particular switch of a switching fabric is associated with a virtual switch address. In response to a determination that the host destination address is associated with the virtual switch address, the method may also include encapsulating the packet with the virtual switch address as a destination fabric address, where the virtual switch address is associated with a virtual switch including a first physical switch and a second physical switch. The method may further include selecting one of the first physical switch and the second physical switch as a routing path. The method may further include routing the packet to the selected physical switch based on the virtual switch address and transmitting the packet from the selected physical switch to a client switch.
