Multiprocessing & multithread capsules
|
|
|
|
– |
Few node OS/EE seems to lack support for complex
|
|
|
application execution model. But, our experience is
that for the
|
|
middle-box model, such models are indispensable
(MPEG-2
|
|
|
decode/ reencode threads)

Event driven model?
|
|
|
|
– |
Few OS/EE have been modeled as 100% event driven
model.
|
|
|
However, a mixed model perhaps is desirable. After
all a
|
|
|
continuous data stream can cause havoc in
performance in
|
|
|
event driven I/O.

Cost of structural conversion?
|
|
|
|
– |
Have active network community thought about legacy
|
|
|
applications? ANTS and few others requires
middle-box to
|
|
|
cast in a specific program forma. It will be nice to
have an
|
|
|
automatic tool which will reengineer a middle box
written in
|
|
|
legacy forma to
that forma.
