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.

To Unicast or To Multicast
White Papers TCP/IP has evolved over the last two decades into a solid unicast protocol that has proven itself in all networks and is a key factor in the success of the Internet. This paper examines the merits of unicast and multicast for different messaging...

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.

Multicast - What Is It?
White Papers When multiple receivers are required to get the same data at approximately the same time, multicast is a more efficient way of delivering data than unicast. A unicast packet has a single source IP address and a single destination IP address.

A Dynamic Stateful Multicast Firewall
White Papers Inspired by the "Stateful" operation of unicast firewalls, multicast firewall blocks unsolicited multicast packets by maintaining state information on multicast group membership and unicast interactions.

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...

Net ads enter new dimension
News In January, New York-based Unicast, the producer of a TV-like pop-up it calls the "superstitial", introduced an expanded format that caters to TV advertisers. Shortly after, Unicast signed a deal with technology provider Klipmart to inject its ads...

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...

MPLS Multicast Traffic Engineering
White Papers This paper defines first the multicast traffic engineering and studies after its particularity comparing to unicast traffic engineering. This paper studies merging multicast and MPLS. The paper presents a taxonomy of different MPLS proposals for...

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.

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...

SIP: Protocol Overview
White Papers SIP sessions involve one or more participants and can use unicast or multicast communication. The Session Initiation Protocol (SIP) is a signaling protocol for initiating, managing and terminating voice and video sessions across packet networks.

TCP Support for Sensor Networks
White Papers TCP would be useful for tasks, where reliable unicast is appropriate, but the high bit error rates in wireless sensor networks lead to energy inefficiencies reducing the sensor network lifetime. Communication between sensors and controlling...
