When sending a message, check the cache for the given destination. If there is a hardware address in the cache for the destination, send the message straight to that address. Otherwise, broadcast the message.

### Optional: Broadcast address
|
||||
Packets addressed to the broadcast address, an address of just the tilde character, `~`, ASCII 126, can optionally be received by all nodes of the same layer 2 network. While a node MAY forward a broadcast packet to other nodes, it SHOULD NOT, unless both sides of the forward are prepared to handle such a packet, to avoid it going around the entire layer 3 network.

Packets addressed to the broadcast address, an address beginning with the tilde character, `~`, ASCII 126, can optionally be received by all nodes of the same layer 2 network.

|

### Optional: Multicast
|
||||
A multicast packet has a specially formatted address part.
|
||||
The address must be a list of valid addresses, seperated by the tilde character, `~`, ASCII 126.
|
||||
For example, to send to nodes `a` and `b`, the address in the packet would be `a~b`.

|

For example, to send to nodes `a` and `b`, the address in the packet would be `~a~b`.
|
||||
|
||||
Each node should send multicasts as layer 2 broadcasts, unless it is known (using the address cache) that all layer 3 destination addresses have to be sent to or forwarded by one layer 2 address.
