10/03/2002 - 02/02/2005:

RRC01:

• Announced as normal

RRC03:

• Announcements at 00:00h, 04:00h, 08:00h, 12:00h, 16:00h and 20:00h (UTC)
• Withdrawals at 02:00h, 06:00h, 10:00h, 14:00h, 18:00h and 22:00h (UTC)

Routing Beacon Address Schema

Prefix:	RRC:	Location:
195.80.233.0/24	RRC01 - LINX	London, UK
195.80.233.0/24	RRC03 - AMS-IX	Amsterdam, NL

All beacon prefixes are now announced with additional attributes. We now overload the BGP AGGREGATOR attribute to tag each announcement with a timestamp, a sequence number and the identifier of the RRC making the announcement. These are encoded as follows:

AGGREGATOR IP ADDRESS: 10.x.y.z, where x, y and z form a 24-bit count of the number of seconds between the start of the month and the time of the announcement.

AGGREGATOR AS NUMBER: 64512 + n, where n is a 10-bit number encoded as

    MSB                                   LSB
    +---+---+---+---+---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
    +---+---+---+---+---+---+---+---+---+---+
    |    RRC ID     |    Sequence Number    |
    +---+---+---+---+---+---+---+---+---+---+

Adding 64512 brings the resulting number into the private AS number range.

Experimental: From 25/09/2003

an additional prefix 195.80.239.0/24 has been announced from all RRCs. This acts as an "anchor" to help differentiate between intentional beacon-related routing activity and other activity. The anchor prefix is announced with the Aggregator attribute set as follows:

Aggregator IP Address: 10.255.255.255
Aggregator AS Number: 64512 + rrc-id * 64
