In HSDN, in order to acquire similar TE and security performance as in SDN multicast, for each multicast group, we firstly leverage unicast
routing to redirect the multicast packets to an appropriate SDN node which serves as the core node, and afterwards route the packets to the destinations whereas the multicast routing is utilized.
App features include full VLAN support, clean switching between flows, sophisticated synchronising, PTP support, 10 frames of video delay, unicast
and multicast transmission support, signal status monitoring, user definable traffic shaping, and support for AMWA NMOS IS-04 and IS-05.
 explained that the substitution of multicast service with unicast
service is not viable because as the number of subscribers increases, the required bandwidth increases.
To solve these defined problems, this paper proposed efficient unicast
routing and multicast forwarding algorithm.
The objective of this paper is to propose a novel method to reduce the bandwidth occupancy of the unicast
traffic consumed during channel changes by enabling communication between STBs.
From this perspective is obvious the great advantage that multicast networks have over unicast
, where the fact that multicast sending reduces the necessary bandwidth requirement, since this type of communication uses distribution trees for transporting data packets to the destinations of a particular receptor "group".
Quickplay said that the acquisition supports its strategy to enable the monetisation of engaging premium viewing experiences on any device or network by using multicast (one-to-many), and unicast
(one-to-one) technologies that leverage 4G LTE Broadcast eMBMS, WiFi, 3G, and 4G to launch new services or enhance existing services with dramatically improved economics and scale.
Popular and common data will be intelligently delivered to the mass market via the broadcast platform while individualized content will be delivered over the unicast
platform, thereby optimizing traffic delivery.
In the present era, Information exchange can be mainly classified as unicast
(one-to-one), broadcast (one-to-all) and multicast (one-to-many).
Three basic transport technologies including unicast
, broadcast, and multicast can be adopted for delivering mobile IPTV streams.
In traditional in-network aggregation, many packets with the same (next-hop) destination are aggregated into one big packet and the aggregated packet is sent along the routing path by unicast
