Question Of The Day: 22 October, 2008

Yesterday’s QoD:

Packet interleaving, packet fragmentation, and packet resequencing are all feature of which technology?

Here are the results:

Answer %
Multilink PPP 49%
Frame Relay Traffic Shaping (FRTS) 34%
RTP Header Compression 10%
Weighted Random Early Detection (WRED) 7%

The answer: Multilink PPP…..and Frame Relay Traffic Shaping?

I thought that I had finally got you guys as the answer that I was looking for was Multipoint PPP:

Multilink PPP
At the highest level, MLP provides packet interleaving, packet fragmentation, and packet resequencing across multiple logical data links. The packet interleaving, packet fragmentation, and packet resequencing are used to accommodate the fast transmission times required for sending real-time packets (for example, voice packets) across the network links. MLP is especially useful over slow network links (that is, a network link with a link speed less than or equal to 768 kbps).

Frame Relay Traffic Shaping was meant to be a red herring, but you can use frame-relay fragment to achieve fragmentation.  Accomplishing interleaving in FRTS is a bit of a stretch as you can create a policy-map with priority configured and call that policy map from the FRTS map-class.  I suppose this depends on your interpretation of the question.

UPDATE: Ummm….strike that.  FRTS does not = map-class.  You can configure a number of features under a map-class but that does not mean that your using FRTS.
