  One of the most discussed features offered by Information-centric Networking
(ICN) architectures is the ability to support packet-level caching at every
node in the network. By individually naming each packet, ICN allows routers to
turn their queueing buffers into packet caches, thus exploiting the network's
existing storage resources. However, the performance of packet caching at
commodity routers is restricted by the small capacity of their SRAM, which
holds the index for the packets stored at the, slower, DRAM. We therefore
propose Object-oriented Packet Caching (OPC), a novel caching scheme that
overcomes the SRAM bottleneck, by combining object-level indexing in the SRAM
with packet-level storage in the DRAM. We implemented OPC and experimentally
evaluated it over various cache placement policies, showing that it can enhance
the impact of ICN packet-level caching, reducing both network and server load.
