    Abstract: A controller device for a network provides data associated with pipeline capabilities of a programmable switch. The programmable switch receives data associated with pipeline capabilities of the programmable switch. The pipeline capabilities include a plurality of flow tables and allowable table transitions for each of the flow tables. The programmable switch determines that a first flow table and a second flow table are mutually independent based on the allowable table transitions for each of the flow tables. The programmable switch configures a pipeline for data flow in the computing device, the pipeline comprising a plurality of pipeline stages, a particular pipeline stage comprising the first flow table and the second flow table.

    Abstract: This disclosure describes various methods, systems, and devices related to identifying path changes of data flows in a network. An example method includes receiving, at a node, a packet including a first path signature. The method further includes generating a second path signature by inputting the first path signature and one or more node details into a hash function. The method includes replacing the first path signature with the second path signature in the packet. The packet including the second path signature is forwarded by the node.

    Abstract: Address support and network address transparency may be provided. First, a border device may receive a processed network configuration parameter request having an address of a subnet to which a client device is associated and information data in an information field of the network configuration parameter request. The information data may comprise an address of a network device and an identifier of the subnet to which the client device is associated. Next, the border device may encapsulate the processed network configuration parameter request with the information data extracted from the processed network configuration parameter request. The border device may then forward the encapsulated network configuration parameter response to the network device.

    Abstract: In one embodiment, a method is performed at a controller of a fabric that is connected to a first seed device in the fabric. The method includes obtaining a connectivity graph of the fabric including the first seed device. The method further includes causing the first seed device to send a first request to a first neighboring device in the connectivity graph via a first interface of the first seed device connectable to the first neighboring device. The method also includes assigning fabric component properties to devices in the fabric based at least in part on a first message from the first seed device, where the first seed device generates the first message based at least in part on a first response from the first neighboring device received via the first interface. The method additionally includes converting the first neighboring device to a second seed device in the fabric.

    Abstract: This disclosure describes various methods, systems, and devices related to identifying an issue in a network using a probe packet. An example method includes identifying an expired data packet transmitted in a network and addressed to a destination; generating a probe packet addressed to the destination; and forwarding the probe packet. When the probe packet is received, a report indicating a routing loop in the network can be transmitted to an administrator.
