Proxy-Based Distribution of Streaming Video Over Unicast/Multicast Connections
White Papers Then they quantitatively explored the impact of the choice of transmission scheme, cache allocation policy, proxy cache size, and availability of unicast versus multicast capability, on the resultant transmission cost.

SBQ: A Simple Scheduler for Fair Bandwidth Sharing Between Unicast and Multicast Flows
White Papers This paper proposes a simple scheduler called SBQ (Service-Based Queuing) to share the bandwidth fairly between unicast and multicast flows according to a new definition of fairness referred as the inter-service fairness.

Establishing a Trade-Off Between Unicast and Multicast Retransmission Modes for Reliable Multicast Protocols
White Papers Existing multicast protocols adopt a static packet retransmission scheme (unicast or multicast) to retransmit these packets, often leading to performance loss due to wasting bandwidth resources. The conventional approach to reliable multicast in...

Unlimited mobile TV for the mass market
White Papers Mobile TV is already booming on existing cellular infrastructures in unicast mode. But unicast is not optimized to deliver the same content to many users at the same time, and this prevents mass-market deployment.

Publishers pull pop-ups
News The ads, which are supplied by technology developer Unicast, are outside the definition of pop-up ads, according to Unicast spokeswoman Allie Shaw. Shaw said the consumer backlash to pop-ups is a boon to Unicast's business, which is focused on a...

HEAT: Scalable Routing in Wireless Mesh Networks Using Temperature Fields
White Papers Existing unicast routing protocols like for example AODV are not suited well for wireless mesh networks as in such networks, most traffic flows between a large number of mobile nodes and a few access points with Internet connectivity.

Pipelined Broadcast on Ethernet Switched Clusters
White Papers This paper considers unicast-based pipelined broadcast schemes for clusters connected by multiple Ethernet switches. By splitting a large broadcast message into segments and broadcasting the segments in a pipelined fashion, pipelined broadcast may...

RIP Net neutrality?
Talkback How about beating down spam and botnets, block non unicast traffic, block inherently insecure and chatty protocols like SMB and keeping out overhead like PR hyped Sender ID out first? That would save a bundle in more then one way.

Performance Evaluation of Approximation Algorithms for Multipoint Relay Selection
White Papers In Mobile Ad hoc NETworks (MANET), the selection of Multipoint Relays provides an efficient routing scheme for efficient broadcast and shortest-path unicast. As such a selection is NP-hard, a heuristic has been designed and effectively implemented...
