  • Patent number: 10484465
    Abstract: The processing of data packets sent over a communication session between a host and a server by a service gateway includes processing a data packet using a current hybrid-stateful or hybrid-stateless processing method. The processing then checks whether a hybrid-stateless or hybrid-stateful condition is satisfied. When one of the sets of conditions is satisfied, the process includes changing from a hybrid-stateful to a hybrid-stateless processing method, or vice versa, for a subsequently received data packet. If the conditions are not satisfied, the process continues as originally structured.

  • Patent number: 10447775
    Abstract: Provided are methods and systems for balancing servers based on a server load status. A method for balancing servers based on a server load status may commence with receiving, from a server of a plurality of servers, a service response to a service request. The service response may include a computing load of the server. The method may continue with receiving a next service request from a host. The method may further include determining, based on the computing load of the server, whether the server is available to process the next service request. The method may include selectively sending the next service request to the server based on the determination that the server is available to process the next service request.

  • Patent number: 9961135
    Abstract: A method, system, and computer program product for balancing servers based on server load status, include: receiving from a server a service response to a service request, the service response including a result from a processing of the service request and a server status indicating a computing load status of the server; obtaining the server status from the service response; receiving a next service request from a host, the next service request comprising a Uniform Resource Locator (URL); determining that the server is configured to process the URL; determining whether the server status indicates that the server is available to process the next service request; and in response to determining that the server status indicates that the server is available to process the next service request, sending the next service request to the server.

  • Patent number: 8897154
    Abstract: Exemplary embodiments for processing, by a service gateway, data packets sent over a communication session between a host and a server are disclosed. The service gateway processes data packets using a hybrid-stateful or hybrid-stateless processing method, depending on whether a hybrid-stateless or hybrid-stateful condition is satisfied. When the condition is satisfied, the service gateway allows for the changing from a hybrid-stateful to a hybrid-stateless processing method, or vice versa, for a subsequently received data packet. Otherwise, the service gateway continues processing the subsequently received data packets using the current hybrid processing method.
