"""SAP Router packet
This packet is used for general SAP Router packets. There are (at least)
five types of SAP Router packets:
1. Route packets. For requesting the routing of a connection to a
remote hosts. The packet contains some general information and a
connection string with a list of routing hops (:class:`SAPRouterRouteHop`).
2. Administration packets. This packet is used for the SAP Router to
send administrative commands. It's suppose to be used only from the
hosts running the SAP Router or when an specific route is included in
the routing table. Generally administration packets are not accepted
from the external binding.
3. Error Information packets. Packets sent when an error occurred.
4. Control Message packets. Used to perform some control activities,
like retrieving the current SAPRouter version or to perform the SNC
handshake. They have the same structure that error information
packets.
5. Route accepted packet. Used to acknowledge a route request
("NI_PONG").
Routed packets and some responses doesn't fill in these five packet
types. For identifying those cases, you should check the type using the
function :class:`router_is_known_type`.
