PS8 is a switch for distributing TCP and UDP traffic to different outputs depending on the TCP/UDP port number.

The switch is cascadable; traffic that is not TCP, UDP or doesn't match parameterized port numbers is forwarded out the aux terminal.

Prior to AppLogic 2.1.1, PS8 is in the proto catalog.

Resource	Minimum	Maximum	Default
CPU	0.05	4	0.05
Memory	64 MB	128 MB	64 MB
Bandwidth	1 Mbps	1 Gbps	1 Mbps

Note: the amount of memory given to PS8 does not affect its throughput. (note: verify and consider limiting the max amount of memory to some small amount, like 128M)

Terminals

name	dir	prot.	description
`in`	in	any	common input. Traffic sent to 'in' is directed to one of the outputs, based on the protocol and port number
`out1-out8`	out	any	outputs. What traffic goes to a particular output is configured through the appliance properties. Any and all of these outputs can be left unconnected; traffic directed to unconnected outputs will be discarded.
`aux`	out	any	cascade output. Incoming traffic that is not directed to any of the `out1-out8` outputs is sent out this terminal. Also, any IP traffic that is not TCP or UDP (i.e., does not have port numbers) is also sent out through this terminal. The terminal can be left unconnected

Properties

name	type	description
`outX_protocol`	string	IP protocols to forward to output `outX`. Allowed values are: `none`, `tcp`, `udp`, `both`. Default is `none` (forwarding disabled).
`outX_in_port`	string	Port(s) to forward through `outX`. If more than one port need to be forwarded, ports can be comma- or space-separated. The ports can be listed by number or by their common name. Default is empty (no forwarding); if a protocol is specified for the output, this property must be set to a non-empty value.
`outX_out_port`	string	Output port to which to forward traffic. If left empty, the output port is the same as the input port. This property allows for easy recoding (e.g., port 8080 to port 80). If the input port is specified as a list, this property must be left empty. Output ports can be specified either as a number (e.g., `80`) or as port name (e.g., `http`). Default: empty (same as input).
