As we read up on this streaming proxy design, we will continue to review the analytical results from the tradeoff between delay startup ratio and the byte hit ratio.  What we had said so far was that the change in the delay with respect to the change in the byte hit is always greater than 1 when the percentage of the startup length and the percentage of the reserved cache space is less than 50%. This gives a solid basis to giving a higher priority to the caching of the startup length of objects in the replacement policy. We now study the proposed replacement policy design.
This technique is called the improved adaptive lazy segmentation strategy. In order to significantly reduce the startup latency with a small decrease of byte hit ratio, a three phase iterative replacement policy is considered. The least utility value  media object is chosen as the victim for eviction from the cache.And the segment of this object is evicted in one of two phases as follows:
In the first phase, if the object is fully cached, the object is segmented by the lazy segmentation method The first two segments are kept and the remaining segments are evicted right after the segmentation is completed.
In the second phase, if the object is partially cached with more than one segment, the last cached segment of this object is evicted.
In the third phase, if the victim has only the first segment and is to be replaced, then its startup length and base segment length is compared. If the startup length is less than the base segment length, the base segment length is kept and the rest is replaced. Otherwise it is totally replaced. The utility value of the media object is updated after each replacement and this process repeats iteratively until the required space is found.
