US 11,457,095 B1 · Stateless communication using a stateful protocol

Abstract

Embodiments are directed to stateless communication using a stateful protocol. One or more NTMAs may establish a connection with a client computer based on data exchanged with a the client computer using the stateful protocol. The exchanged data may include validation information provided by the one or more NTMAs. The exchanged data and other information associated with the connection may be discarded from one or more memories of the one or more NTMAs. A network packet communicated over the network using the stateful protocol may be obtained. Verification information and candidate validation information may be generated based on one or more characteristics of the network packet. The network packet may be validated based on a comparison of the verification information and the candidate validation information. A reply that adheres to the stateful protocol may be provided to the client computer based on the validated network packet.

Dependent claims

A method for stateless communication using a stateful protocol implemented by a network traffic management system that comprises one or more network traffic management apparatuses (NTMAs) that execute instructions to perform the actions of the method, comprising:

employing the stateful protocol to establish a connection between a client computer and the one or more NTMAs;
discarding state information for the connection from the one or more NTMAs;
generating verification information based on a portion of the network packet that an endpoint generates during initiation of a connection with another endpoint and candidate information based on another portion of the network packet that refers to connection information that the endpoint extracts or generates from a characteristic of the network packet;
in response to using the stateful protocol to receive a network packet, validating the network packet based on a comparison of the verification information for the portion of the network packet and the candidate validation information for the other portion of the network packet;
and
providing a reply to the client computer based on the validated network packet, wherein the reply adheres to the stateful protocol.

3 more elements

A processor readable non-transitory storage media that includes instructions for stateless communication using a stateful protocol, wherein execution of the instructions by one or more hardware processors of one or more network traffic management apparatuses (NTMAs) perform actions, comprising:

employing the stateful protocol to establish a connection between the client computer and the NTMA;
discarding state information for the connection from the NTMA;
generating verification information based on a portion of the network packet that an endpoint generates during initiation of a connection with another endpoint and candidate information based on another portion of the network packet that refers to connection information that the endpoint extracts or generates from a characteristic of the network packet;
in response to using the stateful protocol to receive a network packet, validating the network packet based on a comparison of the verification information for the portion of the network packet and the candidate validation information for the other portion of the network packet;
and
providing a reply to the client computer based on the validated network packet, wherein the reply adheres to the stateful protocol.
