Described are platforms, systems, and methods for actuating transmission control protocol/Internet protocol (TCP/IP) through a method comprises: identifying a computer workload during a handshake process for establishing a network connection with a remote host; configuring, based on the computer workload, one or more TCP/IP parameters of the network connection; and completing the handshake process to establish the network connection with the remote host.

Application aware TCP performance tuning on hardware accelerated TCP proxy services

Described are platforms, systems, and methods for providing an in-line, transparent Transmission Control Protocol (TCP)/Transport Layer Security (TLS) proxy. In one aspect, a programmable input output (IO) device comprises at least one advanced reduced instruction set computer (RISC) machine (ARM) core communicably coupled to at least one central processing unit (CPU) core of a host device; a programmable P4 pipeline comprising a cryptographic offload subsystem; and a memory unit. The programmable IO device executing instruction stored on the memory unit comprising: establishing a session for an incoming TCP connection received from a remote host via the at least one ARM core; processing data packets received from the remote host via the programmable P4 pipeline; decrypting the received data packets via the cryptographic offload subsystem; and providing the decrypted data packets to the host device.

Proxy service through hardware acceleration using an IO device

Described are platforms, systems, and methods for upgrading firmware on a programmable input output (IO) device. In one aspect, a method executed by the programmable IO device comprises: receiving, from a north-bound entity, a request to upgrade firmware installed on at least one CPU core; disabling flow-miss traffic to the at least one CPU core; redirecting the flow-miss traffic to an off-box service; providing a configuration for the programmable IO device to the off-box service; redirecting traffic to the off-box service; upgrading the firmware installed on the at least one CPU core; upgrading at least one program running in the data plane; reprograming a forwarding state provided by the off-box service; disabling the redirection of the traffic to the off-box service; and providing, to the north-bound entity, a notification indicating a completion of the upgrade.

Zero packet loss upgrade of an IO device

Methods and systems for upgrading an intelligent server adapter (ISA) with reduced downtime that affects performance are provided. The method includes, from a main agent, initiating a backup agent that includes critical functions of the ISA and runs in a tight loop, isolated from other components. The main agent transfers critical duties to the backup agent and shuts down before performing the upgrade. After upgrading itself and other system components, the main agent retrieves the duties from the backup agent, and may terminate the backup agent.
