Abstract: The present technology provides a low latency stateful serverless networking protocol to support persistent multiplayer state synchronization. The fundamental system is a key-value data store that uses transactions to ensure state coherency synchronized across many clients. Each client subscribes to state updates as well as orchestrates state writes by attempting to lock and write the next available key and then assumes that its state update will succeed to reduce perceived latency. If the key was incorrectly assumed to be submitted in the right order, the client rolls back its assumption and tries the process again.

Abstract: Embodiments described herein describe a network tester that is configured to perform packet modification at an egress pipeline of a programmable packet engine. A packet stream is received at an egress pipeline of an output port of the programmable packet engine, wherein the output port includes a packet modifier. Packets of the packet stream are modified at the packet modifier. The packet stream including modified packets is transmitted through an egress pipeline of the output port.
