The document discusses the ROMUS project which aims to improve the user experience of multimedia streaming services in dynamic environments. The project focuses on three main areas: adaptation and robustness in live peer-to-peer streaming using techniques like scalable video coding and network coding; video quality assessment; and exploiting multicore processing. It summarizes results on protocols like Chameleon, a novel adaptive P2P streaming protocol, and frameworks to distribute multimedia workloads across computer clusters.
A HYBRID PUSH-PULL OVERLAY NETWORK FOR PEER-TO-PEER VIDEO STREAMINGijp2p
In this paper, we have proposed a hybrid push-pull protocol for peer-to-peer live video streaming. The
main goal of this research is to minimize the network end-to-end delay in comparison to pure mesh
networks. Hybrid protocols, in most cases, suffer from complex construction and maintenance. Therefore,
our proposed protocol uses a pure mesh topology and a single layer video coding. In summary, our pushpull protocol has two parts. The pull-based part which is done on the mesh network, and the push-based
part which consists of two phases: parent selection and tree construction. When a push procedure appears,
it is very important to prevent data redundancy. To satisfy this condition, we have introduced a parent
selection method. In this method, by parent selection based on the minimum arrival time, the most stable
node will be selected. This node has the advantage of maximizing the expected service time of the tree.
Using this method, there is no need for maintaining any extra information and topology control data.
Finally, we do performance evaluation using OMNeT++ simulator. The simulation results show that the
proposed architecture has better performance in start-up delay, end-to-end delay, and distortion than pure
mesh-based network.

Mpls vpn using vrf virtual routing and forwardingIJARIIT
Multi-Protocol Label Switching (MPLS) which was introduced by Internet Engineering Task Force (IETF) is
usually used in communication networks which started attracting all the internet service provider(ISP) networks with its
brilliant and excellent features that provide quality of services (QOS)and guarantees to traffic which carries data from one
network to another network directly through labels.
Virtual Private Network (VPN) is one of the highly useful MPLS applications which allow a service provider or a large enterprise
network to offer network Layer VPN services that guarantee and carries traffic securely and privately from customer’s one to
another through the service provider’s network. To support multiple customers that Customers Request for secure, reliable,
private and ultrafast connections over the internet MPLS VPN standards include the concept of a virtual router. This feature
called a VRF table. VRF or Virtual Routing and Forwarding technology that permit a router to have various routing table or
multiple VPN at the same time that they are located in the same router but they are independent and also the VRF feature in
VPN now allows different customers to use same IP addresses connected to the same ISP. A VRF exists inside a single MPLS
router and typically routers need at least one VRF for each customer attached to that particular router.
Internet Path Selection on Video QoE Analysis and ImprovementsIJTET Journal
Abstract— Systematically study a large number of Internet paths between popular video destinations and clients to create an empirical understanding of the location, existence, and repetition of failures. Finding ways to lower a providers costs for real-time, Internet protocol television services through a Internet protocol television architecture and through intelligent destination-shifting of selected services investigate ways to recover from Quality of Experience degradation. Using Live Television and Video on Demand as examples, we can take advantage of the different deadlines associated with each service to effectively obtain these services. Designing and implementing a prototype packet forwarding module called source initiated frame restoration. We implemented source initiated frame restoration on nodes and compared the performance of source initiated frame restoration to the default Internet routing. We found that source initiated frame restoration outperforms IP path selection by providing higher on-screen perceptual quality. These failures are mapped to the desired video quality in need by reconstructing video clips and by conducting user surveys. We can then examine ways to recover from Quality of Experience degradation by choosing one hop detour paths that preserve application specific policies. Path ranking methodology is used to find the path which contain high quality videos with low cost and occupies very low memory space. By ranking videos according to their quality, size, and cost, the top ranking videos can be retrieved by the client.
Analyzing Video Streaming Quality by Using Various Error Correction Methods o...IJERA Editor
Transmission video over ad hoc networks has become one of the most important and interesting subjects of study for researchers and programmers because of the strong relationship between video applications and frequent users of various mobile devices, such as laptops, PDAs, and mobile phones in all aspects of life. However, many challenges, such as packet loss, congestion (i.e., impairments at the network layer), multipath fading (i.e., impairments at the physical layer) [1], and link failure, exist in transferring video over ad hoc networks; these challenges negatively affect the quality of the perceived video [2].This study has investigated video transfer over ad hoc networks. The main challenges of transferring video over ad hoc networks as well as types of errors that may occur during video transmission, various types of video mechanisms, error correction methods, and different Quality of Service (QoS) parameters that affect the quality of the received video are also investigated.

Priority scheduling for multipath video transmission in wmsnsIJCNCJournal
In video data transmission over Wireless Multimedia Sensor Networks (WMSNs), in which network
congestion and link failures are main characteristics, providing Quality-of-Service (QoS) is challenging. In
such situation, using multipath routing protocols along with efficient packet scheduling can improve the
performance of video delivery over sensor networks. In this paper we propose a new packet scheduling
mechanism for multipath video transmission over WMSN. Since, different video frame types in a
compressed video stream have different impact on the perceived video at the receiver; our proposed
scheme for video packet scheduling is content aware that schedules transmission of different video packets
over different paths. For this purpose, condition of each routing path is periodically evaluated and the high
priority video packets are transmitted through high quality paths. Simulation results show that our
proposed scheduling improves the quality of the perceived video at the receiver, considerably.

PEER-TO-PEER LIVE STREAMING AND VIDEO ON DEMAND DESIGN ISSUES AND ITS CHALLEN...ijp2p
Peer-to-Peer Live streaming and Video on Demand is the most popular media applications over the
Internet in recent years. These systems reduce the load on the server and provide a scalable content
distribution. A new paradigm of P2P network collaborates to build large distributed video applications
on existing networks .But, the problem of designing the system are at par with the P2P media streaming,
live and Video on demand systems. Hence a comprehensive design comparison is needed to build such
kind of system architecture. Therefore, in this paper we elaborately studied the traditional approaches for
P2P streaming architectures, and its critical design issues, as well as practicable challenges. Thus, our
studies in this paper clearly point the tangible design issues and its challenges, and other intangible
issues for providing P2P VoD services.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

• Limita4ons
of
tradi4onal
live
P2P
streaming
systems
– No
differen4ated
QoS:
users
must
receive
the
same
stream
regardless
of
their
bandwidth
(high
capacity
users
perceive
the
same
low
quality
as
average
users)
– No
con4nuous
playback/black
block
images:
with
the
current
best-‐effort
Internet
and
the
peer
dynamics,
the
streaming
quality
at
each
peer
is
easily
impaired
(when
the
available
bandwidth
at
a
peer
drops
below
the
streaming
rate,
it
may
suffer
playback

hypotheses
• Adaptable
coding
techniques
(such
as
SVC)
can
bring
significant
benefits
in
terms
of
differen4ated
QoS
and
con4nuous
playback
to

networking
can
improve
the
robustness
of
the
P2P
system
with
respect
to
network
fluctua4ons
and
peer
dynamics
• Quality-‐aware

23. P2G
main
features
• The P2G framework allows developers to
express continuous multimedia workloads with
fine grained parallelism in a single language
• The runtime decides itself how a program should
be partitioned, and which execution node should
execute them
• Open source at http://p2gproject.org

26. Conclusions
(1)
• The development of a simulation model to simulate and
evaluate novel adaptive and robust live P2P video streaming
solutions is essentially important for long-term research in the
field
• It is essential to find solutions to important limitations of live
P2P streaming technologies. Our basic solutions and findings
could be inherited by other initiatives to build a more practical
protocol taking other network metrics into account.
• Tools and guidelines for how to design real time video
streaming infrastructure adopting SVC techniques is crucial
for being able to provide the best possible user experience
with minimal visual distortion.

27. Conclusions
(2)
• Our results indicate that quality adaptation can
outperform constant low quality, but frequency and
amplitude, as well as switching patterns are relevant
• Multicore processor scheduling to handle multimedia
workloads on individual peer nodes will be important in
the future and may improve the multimedia experience of
the user even further.
• Our results shows the feasibility of providing a
programming framework for automatic parallel, real-time
processing of multimedia workloads exploiting
heterogeneous multicore processors.
