BGP Monitoring
BGP is the world’s best information hiding protocol <tm>. It only gives me the router’s best path

OpenBMP is an open-source collector that implements BMP to store and maintain multiple address family topologies in both real-time and point-in-time (historical)
BGP data is decoded ,stored in local or external a database and accessed via standard ODBC/MySQL driver or via the API by custom applications
Operator access directly or via the OSS/BSS
Cisco continuously develop , certify and add new custom applications with integrated dashboard, reports, events to tailor to the operator needs .

Converts mrt data, such as RIS and Route Views to OpenBMP
Yes, you only get the best path view
But it makes backward compatibility possible.
You can inject traditional dumps into openBMP
For longitudinal analysis it may be good to have the old data parsable using the same tools

Implementor Concerns
Compressed or Uncompressed?
Mirror or Extract from RIB
All are Resource / Loading Issues
RIPE OpenBMP

29. Creative Commons: Attribution & Share Alike
Compressed or Not
The "uncompressed" approach requires that every message received from a monitored session must result, 1:1, in a message sent to the monitoring station. Since the potential number of messages received over time is unbounded, and since there are many potential bottlenecks in the system, there are inevitable consequences for system design. One of these is that buffering has to be supplied to absorb bursts on the input side. Another is that exception handling has to be provided for when buffering is exhausted.

30. Mirror or Extract from RIB
Mirroring has the burst buffering & loading problems in previous slide
Extraction from RIB to create stream allows BMP export to control the pace
But it has to be very careful not to change attributes, reorder them, …
So keep a copy of the attribute list in the RIB and generate from RIB
