RE: [RRG] Six/One Router Design Clarifications
|Encap/decap has a potential to be much more difficult if fragmentation
|would be incurred (especially outer header fragmentation); I have hard
|time seeing how you could even implement a line-speed decapsulator
|that would reassemble fragments as required by Full Standard IP RFCs.
This would be reasonably doable. The algorithm is quite well known
(including the well-known bugs) and having hardware execute this algorithm
is not going to be overly difficult. Start by translating a working C
implementation into Verilog and ...
For line rate (for interesting values of line rate), you'd need to buffer
the fragments in static RAM, but this too can be done today.
|As a result for encap/decap schemes I specifically want to see how
|they 100% avoid fragmentation, or describe how they deal with it.
Cue Fred. ;-)
