PPT-Packet Caches on Routers:

The Implications of Universal Redundant Traffic Elimination Ashok Anand Archit Gupta Aditya Akella University of Wisconsin Madison Srinivasan Seshan Carnegie Mellon University. Understandably because these routers are very robust their capable of handling large amounts of tr affic have advanced security fea tures and hold all the informati on pertaining to the network If only these routers needed to be maintained netw ork Although large caches can significantly improve performance they have the potential to increase power consumption As feature sizes shrink the dominant component of this power loss will be leakage However during a fixed period of time the activ ity i caches and data caches are always identical in size or differ by a factor of 2X, but no more. The primary caches range from 8 KB to 128 KB with SA ranging from direct mapped to 8-way. Small instruct . Komputer. . Lanjut. Packet Switching Network. Outline. Why Packet Switching?.
