We used our simulator to explore how the five parameters discussed in
section 
affected the performance of push-caching.
These parameters are summarized in table . The
results of these simulations are presented in
sections through . We
also used our simulator to compare push-caching to client-caching,
where each client caches a small set of popular documents, and
proxy-caching, discussed in section . The results
of these simulations are presented in section
and . We conclude this chapter with a
discussion of push-caching scalability.
