    摘要： A service gateway processes a service request received from a host by: relaying the service request from the service gateway to a server over a service session between the service gateway and the server; determining a service request time for the service session; receiving by the service gateway a service response from the server; determining by the service gateway a service response time; calculating by the service gateway a service processing time for the service request from the service request time and the service response time; comparing the service processing time with an expected service processing time; and updating a server busy indicator for the server in response to the comparing. If the service processing time exceeds the expected service processing time, the server busy indicator is updated to indicate that the server is busy. Otherwise, the server busy indicator is updated to indicate that the server is not busy.

    摘要： 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; checking whether a hybrid-stateless, or hybrid-stateful, condition is satisfied; when the condition is satisfied, changing from a hybrid-stateful to a hybrid-stateless processing method, or vice versa, for a subsequently received data packet; and otherwise, continue processing the subsequently received data packet using the current hybrid processing method.

    摘要： 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.

    摘要： In activating a service, a service gateway retrieves a service table entry using a service or server address of the service entry, where the service table entry has an association with another service entry. An association to the service entry is added and a marker value is set to indicate associations with two service entries. After a time duration, the association with the other service entry is removed, and the marker value is changed accordingly. In deactivating a service entry, the service gateway calculates a hash value for the service or server address of the service entry. After matching the hash value to a hash value of another service entry, an association with the other service entry is added. A marker value is set to indicate associations with two service entries. After a time duration, the association with the service entry is removed, and the marker value is changed accordingly.

    摘要： A system and method for providing a network proxy layer are disclosed. The network proxy layer may receive a connection establishment event for a client connection of an application session and send the client connection event to an application proxy for the application session, the application proxy being associated with an application of a server. Upon establishment of the client connection, the network proxy layer may receive one or more data packets from the client connection. The network proxy layer may further receive a connection establishment event for a server connection of the application session of the server, and receive one or more data packets from the server connection.
