4.2.2 Additional requirements for network infrastructure equipment

Add, at the end of the existing notes, the following new note:

NOTE 3 Although multicast filtering techniques, such as IGMP snooping or CGMP, are not allowed to be
activated, it is acceptable to manually configure individual ports of the switches to block unnecessary traffic flow
(for example to isolate simple sensors from ECDIS and radar).

Table 4 – Destination multicast addresses and port numbers

Add, at the end of Table 4, the following new note:
NOTE The USR1 to USR8 transmission groups can be used, for example, for proprietary data in binary format.

Table 5 – Destination multicast addresses and port numbers for binary data transfer
Replace the existing Table 5 by the new Table 5, as follows:
Category Multicast Destination port
address
a
Simple Binary image transfer 239.192.0.21 to 60021 to 60025
239.192.0.25
b
Re-transmittable binary image transfer 239.192.0.26 to 60026 to 60030
239.192.0.30
a
Address 239.192.0.25, port 60025 is the recommended default for ECDIS route transfer (see IEC 61174).
b
Address 239.192.0.26, port 60026 is the recommended default for VDR image transfer (see IEC 61996-1).
Address 239.192.0.30, port 60030 is the recommended default for ECDIS re-transmittable data blocks for
route transfer (see IEC 61174).

7.2.3.3 Grouping control – g
Replace, in the fifth paragraph, the existing sentences by the following two sentences:

7.3.3.4 Source and destination identifier

Replace the existing title by the following new title:

7.3.3.4 Destination identifier

7.3.6 Sender process for binary image transfer

Add new subclause between title of 7.3.6 and title of 7.3.6.1:
7.3.6.3 General
Each single binary image transfer shall be identified by a unique combination of SrcID and
BlockID (see Table 9). Within the same SrcID, the Device and Channel (see Table 10) shall
be used to distinguish between different data sources of binary image transfers.
NOTE If a single SrcID has multiple needs to send binary images (e.g. ECDIS sending screen image, chart source
information and Route exchange), then each single binary image transfer is identified, for example: ECDIS number
1 send screen image as Device = 1 and Channel = 1, and Chart source information as Device = 1 and Channel = 2.

7.3.6.1 Non re-transmittable sender process
Replace the text of item b) by the following new text:
b) a block identifier is assigned for the image block (if this is the first image, then it is
assigned randomly. Otherwise, the instance identifier of the previous image block + 1 is
used). The BlockID shall be unique for each binary image transfer from the same SrcID;

Replace the text of item e) by the following new text:
e) assign a sequence number, which is assigned to one initially;

7.3.6.2 Re-transmittable sender process

Replace the text of item b) by the following new text:
b) a block identifier is assigned for the image block (if this is the first image, then it is
assigned by randomly. Otherwise, the block identifier of the previous image block + 1 is
used). The BlockID shall be unique for each binary image transfer from the same SrcID;

Replace the text of item e) by the following new text:
e) assign a sequence number, which is assigned to one initially;

Replace, in item i), the text of the third bullet by the following new text:
• go to Step (g);
