= /PUSH =

The push packet is used to request that a node initiate a TCP connection to a
specified node address. It is useful where the receiving node is unable to accept TCP
connections naturally.

== Sending ==

An addressed /PUSH packet should be sent to a hub with direct or proxy access to
the destination leaf node. It can be sent directly by a hub to one of its leaves without
the need for addressing.

== Receiving ==

Upon receiving a /PUSH packet, the local node should initiate a TCP connection to
the elected node address and issue a "push handshake", documented below.

== Payload ==

The network address of the node to contact, including of course the port number.

== Children ==

This packet has no known children at the current time, however it is often used with
the generic addressing child packet "/?/TO" to indicate that it should be forwarded to
a destination.
