A method of obtaining instructions for routing a packet is described that includes receiving a packet having a packet flow identifier that includes a packet source IP address, a packet destination IP address, a packet source port, and a packet destination port and checking whether the packet flow identifier matches a stored instruction. If the packet flow identifier does not match a stored instruction, whether the packet flow identifier matches a stored criteria is checked and if the packet matches a stored criteria, the packet is forwarded to a service manager.
