\par Ethernet to 6LowPan Address Translation
|
||||
|
||||
It should be obvious that since 802.15.4 addresses are 8
|
||||
bytes, and 802.3 addresses are 6 bytes, some form of
|
||||
address translation is needed. These routines provide this
|
||||
|
||||
\par 802.3 Address Formats
|
||||
|
||||
802.3 MAC addresses used here have this form:
|
||||
|
||||
\verbatim
|
||||
+----+----+----+----+----+----+----+----+
|
||||
+ + + + + + TR + GL + MU +
|
||||
+----+----+----+----+----+----+----+----+
|
||||
\endverbatim
|
||||
|
||||
|
||||
It can be seen this is like a normal ethernet MAC address,
|
||||
with GL being the Global/Local bit, and MU being the
|
||||
Multicast/Unicast bit.
|
||||
|
||||
The addition is the 'TR' bit, which if set indicates that
|
||||
the address must be translated when going between 802.15.4
|
||||
and 802.3.
|
||||
|
||||
\par Address Translation
|
||||
|
||||
If the TRANSLATE (TR) bit is CLEAR, this means the 5th and
|
||||
4th LSBytes of the 802.15.4 address are fffe, aka the address
|
||||
has the hexidecial form:
|
||||
|
||||
xxxxxxfffexxxxxx
|
||||
|
||||
\note
|
||||
You should always aim to set the 802.15.4 addresses
|
||||
of the devices on your network to ones that will
|
||||
satisfy this requirement. Some examples are:
|
||||
\note
|
||||
0x02 23 42 ff fe 73 92 28
|
||||
\note
|
||||
0x82 00 82 ff fe cd ee 22
|
||||
|
||||
\note
|
||||
So the most significant octets MUST
|
||||
have bit 0 CLEAR, bit 1 SET, and bit 2 CLEAR. The remaining
|
||||
bits in this octet can be anything.
|
||||
|
||||
If the TRANSLATE bit is SET, this means the address on the
|
||||
802.3 side does not directly convert to an 802.15.4 address.
|
||||
To translate it, the remainder of the octet is used as an
|
||||
index in a look-up table. This look-up table simply stores
|
||||
the 4th, 5th, and 8th octet of the 802.15.4 address, and attaches
|
||||
them to the remaining 5 bytes of the 802.3 address.
|
||||
|
||||
In this way there can be 32 different 802.15.4 'prefixes',
|
||||
requiring only 96 bytes of RAM in a storage table on the
|
||||
802.3 to 802.15.4 bridge.
|
||||
|
||||
Mulitcast addresses on 802.3 are mapped to broadcast addresses on
|
||||
802.15.4 and vis-versa. Since IPv6 does not use 802.3 broadcast,
|
||||
this code will drop all 802.3 broadcast packets. They are most
|
||||
likely something unwanted, such as IPv4 packets that snuck in.
|
||||
|
||||
\par Notes on how addresses are stored
|
||||
|
||||
An 802.15.4 address will be reported for example as:
|
||||
|
||||
0x8877665544332211
|
||||
|
||||
Stored in the array as passed to these functions, it will be:
|
||||
\verbatim
|
||||
array[0] = 0x88;
|
||||
array[1] = 0x77;
|
||||
array[2] = 0x66;
|
||||
etc.
|
||||
\endverbatim
|
||||
|
||||
An 802.3 address will be reported for example as:
|
||||
02:43:53:35:45:45
|
||||
|
||||
Stored in the array as passed to these functions, it will be:
|
||||
\verbatim
|
||||
array[0] = 0x02;
|
||||
array[1] = 0x43;
|
||||
array[2] = 0x53;
|
||||
array[3] = 0x35
|
||||
etc.
