A shared memory packet switch fabric whose scheduling task is distributed to multiple egress schedulers residing on multiple egress control units and whose data storage is distributed to multiple packet buffer units, where the schedulers and the packet buffer units are interconnected via high speed links. The housing member according to the present invention is manufactured in a structure in which the electrically connecting members are integrally formed at the housing member. An inlet conduit is tangentially connected to the wall. These improved models provide a feasible alternative for ascites or experimental metastasis evaluation of novel cancer therapeutics. The solution set is redetermined according to a selected negotiation attribute. The forwarding device sets the packet transfer rule requested by the control device.
