Abstract: A network device receives a data packet including a source address and a destination address. The network device drops the data packet before it reaches the destination address and generates an error message indicating that the data packet has been dropped. The network device encapsulates the error message with a segment routing header comprising a list of segments. The first segment of the list of segments in the segment routing header identifies a remote server. The network device sends the encapsulated error message to the remote server based on the first segment of the segment routing header.

Abstract: A server communicates over a network with a data inspection device (DID) having access to at least portions of a data file, and assists the DID with matching the data file to known data files represented on the server. A hash tree is constructed for each known data file. To construct each hash tree: the known data file is fragmented into contiguous fragments; spaced fragments separated based on an offset schema are selected from the contiguous fragments; and nodes of the hash tree are generated based on hashes of the spaced fragments, but not the skipped fragments. A hash of a fragment of the data file is received from the DID, and it is compared to the hash trees constructed using the offset schema. Compare results are sent to the data inspection device indicating a match or a mismatch between the received hash and the hash trees.

Abstract: A network device, including ports that receive/send data packets from/to a network, receives data packets of multiple traffic flows, and populates a queue in memory with the data packets. The network device periodically updates a fair rate for the multiple traffic flows to converge a length of the queue to a reference length. Specifically, the network device determines a length of the queue, a change in the length from a previous length, and a deviation of the length from the reference length. The network device detects an increase in the change in length above a threshold that is based on the reference length. If the increase is not above the threshold, the network device derives the fair rate from a previous fair rate using proportional integral control. The network device identifies elephant flows among the multiple traffic flows, and sends the fair rate to a source of each elephant flow.

If the first packet is the second type, the first packet is forwarded to the second wireless bridge device via the tunnel or forwarding the first packet to the one or more access points via the first wireless link.
