Abstract: Techniques for accelerated Time series analysis (TSA) in a network are described. Packets from a first network flow at a network element, such as a switch or a router, are trapped using a hardware based TSA engine at the network element. The packets are then reduced into TSA tuples including TSA data points and stored into memory. A software based TSA module performs one or more TSA actions on the stored tuples, where the TSA actions produce analysis results used to determine network performance for the network and network based applications.

Abstract: In some embodiments, a device in a network receives a packet from a sender that is destined for a receiver. The device forms duplicate packets of the packet. The device assigns a sequence number to the duplicate packets based on an identity of the sender and on a flow identifier associated with the packet. The device sends the duplicate packets with the sequence number via different paths in the network towards the receiver.
