Date Added: Dec 2011

For interactive networked applications like web browsing, every Round-Trip Time (RTT) matters. The authors introduce ASAP, a new naming and transport protocol that reduces latency by shortcutting DNS requests and eliminating TCP's three-way handshake, while ensuring the key security property of verifiable provenance of client requests. ASAP eliminates between one and two RTTs, cutting the delay of small requests by up to two-thirds. Modern web sites are widely distributed applications that make interactive procedure calls, in the form of web requests, to servers around the world.
