Bandwidth-Efficient Management of DHT Routing Tables

Tags:
switching

Overview Today an application developer using a Distributed Hash Table (DHT) with n nodes must choose a DHT protocol from the spectrum between O(1) lookup protocols and O(log n) protocols. O(1) protocols achieve low latency lookups on small or low-churn networks because lookups take only a few hops, but incur high maintenance traffic on large or high-churn networks. O(log n) protocols incur less maintenance traffic on large or high-churn networks but require more lookup hops in small networks. Accordion is a new routing protocol that does not force the developer to make this choice: Accordion adjusts itself to provide the best performance across a range of network sizes and churn rates while staying within a bounded bandwidth budget.

Peter Cochrane's Uncommon Sense: Circuit or packet, clean or dirty?

One of the secrets for success is an overall reduction in the number of hops from one point to another and the strict control of the traffic to give priority to all real time applications. It has been widely proven that VOIP and VCOIP can be...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
