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. 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.

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.
摘要翻译：在激活服务时，服务网关使用服务条目的服务或服务器地址检索服务表条目，其中服务表条目与另一服务条目具有关联。添加与服务条目的关联，并且设置标记值以指示与两个服务条目的关联。在一段时间之后，与其他服务条目的关联被去除，并且标记值相应地改变。在停用服务条目时，服务网关计算服务条目的服务或服务器地址的哈希值。将哈希值与另一个服务条目的哈希值匹配后，添加与其他服务条目的关联。标记值被设置为指示与两个服务条目的关联。在一段时间之后，与服务条目的关联被去除，并且标记值被相应地改变。

摘要： Provided are methods and systems for distributing application traffic. A method for distributing application traffic may commence with relaying a first service request for a first service session from a service gateway to a server. The first service request may be received from a host and may be associated with a service request time. The method may further include receiving, from the server, a service response. The service response may be associated with a service response time. The method may continue with calculating a service processing time based on the service request time and the service response time and comparing the service processing time with an expected service processing time. The method may further include receiving, from the host, a second service request for a second service session. The method may continue with selectively relaying the second server request to the server based on the service processing time.

摘要： 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.

摘要： A service gateway processes a service request received from a host based on a dynamic service response time of a server. In an exemplary embodiment, the service gateway relays a service request to a server over a service session between the service gateway and the server; receives a service response from the server; calculates a dynamic service processing time for the service request from a service request time and a service response time; compares the dynamic service processing time with an expected service processing time; updates a server busy indicator for the server in response to the comparing, where the server busy indicator is maintained at the service gateway; and processes future service requests in accordance with the server busy indicator at the service gateway.
