A pass-through server such as an NFS server backed by an iSCSI (Internet Small Computer System Interface) storage server only passes data between the storage server and NFS clients. Ideally it should require at most one data copying operation on sending or receiving, as in normal IP routers. In practice, pass-through servers actually incur multiple data copying operations because they are implemented...
Caching on the edge of the Internet is becoming a popular technique to improve the scalability and efficiency of delivering dynamic Web content. In this paper, we study the challenges in designing a large scale cooperative edge cache network, focusing on mechanisms and methodologies for efficient cooperation among caches to improve the overall performance of the edge cache network. This paper makes...
We present two transformations that convert a class of local-spin mutual exclusion algorithms on the cache-coherent model to local-spin mutual exclusion algorithms on the distributed shared memory model without increasing their time complexity. The first transformation uses registers and test-and-set objects, and does not increase the number of busy-waiting periods. The second transformation uses...
Streaming media objects have become widely used on the Internet, and the demand of interactive requests to these objects has increased dramatically. Typical interactive requests include fast forward and direct jumps. Unfortunately, most of existing streaming proxies are designed for sequential accesses, and only a few solutions have been proposed to maintain additional data structures in the proxy...
