1. A method for processing data packets sent over a communication session between a host and a server by a service gateway, comprising:
- determining, by the service gateway, that a hybrid-stateless condition is satisfied; and
based on the determination that the hybrid-stateless condition is satisfied, processing a subsequently received data packet, by the service gateway, using a hybrid-stateless processing by matching data included in the subsequently received data packet to a service mapping table to determine, based on the match, a server to which the subsequently received data packet is to be sent.

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.

11. A system, comprising:
a service gateway comprising a processor and a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to; determine that a hybrid-stateful condition is satisfied; and in response to determining that the hybrid-stateful condition is satisfied, process a subsequently received data packet using a hybrid-stateful processing method by matching data included in the subsequently received data packet to a service mapping table to determine, based on the match, a server to which the subsequently received data packet is to be sent. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for processing data packets sent over a communication session between a host and a server by a service gateway, the method comprising:
-
determining, by the service gateway, that a hybrid-stateful condition is satisfied; and in response to determining that the hybrid-stateful condition is satisfied, processing a subsequently received data packet by the service gateway using a hybrid-stateful processing method by matching data included in the subsequently received data packet to a session table to determine, based on the matching, a server to which the subsequently received data packet is to be sent. - View Dependent Claims (18, 19, 20)
