摘要： The present invention relates to a network unit in a telecommunication network for forwarding a Layer 2 packet such as an Ethernet packet encapsulating a Layer 3 packet such as an Internet protocol packet in its payload. The Layer 2 packet being received at one of the interfaces of the network unit. The network unit therefore comprises: a forwarding database that comprises associations between an interface of the plurality of interfaces and at least one Layer 3 address. The forwarding database returns upon reception of a Layer 3 address which has a full match with one of said Layer 3 addresses in the forwarding database, the associated interface of the plurality of interfaces; and an extractor for extracting from a payload of the Layer 2 packet a destination Layer 3 address; and a forwarding engine for in response to this extraction, retrieving from the forwarding database and based upon this extracted destination Layer 3 address, the associated interface. Furthermore, the network unit forwards the Layer 2 packet towards the associated interface.

摘要： A method of removing an instance of a stateful session bean from a passive state, and a computer program product to execute this method. An event initiates the removal of said instance of the SFSB from the passive state to a does-not-exist state. Upon that event, a function of a container managing the SFSB is triggered. Said function handles the release of external state objects associated with the instance of the SFSB upon removing the instance of the SFSB. In one preferred embodiment of the method introducing a new type of callback method, said instance of the SFSB is partially reactivated, after calling said new type of callback method on said instance of the SFSB, by setting said instance of the SFSB in a near remove state between the passive state and the does-not-exist state.
