LTE network: How it all comes together architecture technical posterDavid Swift
Mobile network operators that want to deploy LTE now want to do so on their own terms. They want to roll out ultrafast mobile broadband safe in the knowledge that one vendor’s solution will work efficiently with another, while delivering the high level of service that subscribers expect. A standards-based network will ensure the goal is met and help drive down cost for operators, but understanding how to pull it all together can be a challenge. So how does it all come together?
The new 5G unified air interface is being designed to not only vastly enhance mobile broadband performance and efficiency, but also scale to connect the massive Internet of Things and enable new types of services such as mission critical control that require ultra-low latency and new levels of reliability and security. The new design will unify diverse spectrum types and bands, scale from macro deployments to local hotspots and efficiently multiplex the envisioned 5G services across an extreme variation of requirements.

Overview of SCTP (Stream Control Transmission Protocol)Peter R. Egli
Overview of SCTP (Stream Control Transmission Protocol), outlining the main features and capabilities of SCTP.
SCTP is a transport protocol that overcomes many of the shortcomings of TCP, namely head-of-line blocking and stream-oriented transmission.
SCTP supports multiple streams within a connection and preserves boundaries of application messages thus greatly simplifying communication.
Additionally, SCTP supports multi-homing which increases availability in applications with high reliability demands.
SCTP inherits much of the congestion, flow and error control mechanisms of TCP.
SCTP has its roots in telecom carrier networks for use in transitional voice over IP scenarios.
However, SCTP is generic so that it is applicable in many enterprise applications as well.

MQTT - MQ Telemetry Transport for Message QueueingPeter R. Egli
Description of message queueing (MQ) protocol for the transport of telemetry data (MQTT - MQ Telemetry Transport).
MQTT is a protocol designed to fit the needs of Internet of Things scenarios. It is lightweight and efficient, but still affords all the features required for reliable messaging between wireless sensor / actor nodes and applications. MQTT decouples producer and consumer of data (sensors, actors and applications) through message brokers with publish / subscribe message queues called topics. MQTT supports different levels of quality of service thus providing the flexibility to adapt to the different needs of applications.
Further features like will and retain messages make MQTT well suited for sensor network scenarios as well as for lightweight enterprise messaging applications.
Open source implementations like Eclipse paho provide ample code for integrating MQTT in your own applications.

NON-INTRUSIVE REMOTE MONITORING OF SERVICES IN A DATA CENTREcscpconf
Non-intrusive remote monitoring of data centre services should be such that it does not require
(or minimal) modification of legacy code and standard practices. Also, allowing third party
agent to sit on every server in a data centre is a risk from security perspective. Hence, use of
standard such as SNMPv3 is advocated in this kind of environment. There are many tools (open
source or commercial) available which uses SNMP; but we observe that most of the tools do not
have an essential feature for auto-discovery of network. In this paper we present an algorithm
for remote monitoring of services in a data centre. The algorithm has two stages: 1) auto
discovery of network topology and 2) data collection from remote machine. Further, we
compare SNMP with WBEM and identify some other options for remote monitoring of services
and their advantages and disadvantages.

A Strategic Approach: GenAI in EducationPeter 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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

2. Plug and Play
Plug and Play (PnP) means that you can connect a device or insert a card
into your computer and it is automatically recognized and configured to work
in your system
3. Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) extends this simplicity to include the entire network,
enabling discovery and control of devices, including networked devices and services,
such as network-attached printers, Internet gateways.
4. 1. Universal Plug and Play (UPnP) is a set of networking protocols that permits
networked devices, such as personal computers, printers, Internet gateways, Wi-Fi
access points and mobile devices to seamlessly discover each other's presence on
the network and establish functional network services for data sharing,
communications, and entertainment.
With UPnP
A device can dynamically join a network, obtain an IP address.
Convey its capabilities, and learn about the presence and capabilities
of other devices.
All automatically; truly enabling zero configuration networks.
6. The Universal Plug and Play Forum defines UPnP Device and Service Descriptions
(originally called Device Control Protocols or DCPs)
The Universal Plug and Play Forum is a group of companies and individuals across the
industry that intend to play a leading role in the authoring of specifications for UPnP
devices and services.
8. Devices, Services and Control Points
The basic building blocks of a UPnP network are devices, services and control
points
9. Devices
A UPnP device is a container of services and nested devices.
Different categories of UPnP devices will be associated with different
sets of services and embedded devices
Consequently, different working groups will standardize on the set of
services that a particular device type will provide
All of this information is captured in
an XML device description document
that the device must host
10. Services
The smallest unit of control in a UPnP network is a service. A service exposes
actions and models its state with state variables.
Similar to the device description, this information is part of an XML service
description standardized by the UPnP forum.
A service in a UPnP device consists of a state table, a control server and an
event server.
o The state table models the state of the service through state
variables and updates them when the state changes
o The control server receives action requests (such as set_time),
executes them, updates the state table and returns responses.
o The event server publishes events to interested subscribers
anytime the state of the service changes.
11. Control Points
A control point in a UPnP network is a controller capable of discovering and controlling
other devices. After discovery, a control point could:
Retrieve the device description and get a list of associated services.
Retrieve service descriptions for interesting services.
Invoke actions to control the service.
Subscribe to the service’s event source. Anytime the state of the service changes, the
event server will send an event to the control point.
13. UPnP leverages many existing, standard protocols.
Using these standardized protocols aids in ensuring interoperability between vendor
implementations
The protocols used to implement UPnP are found in use on the Internet and on local
area networks everywhere.
This prevalence ensures that there is a large pool of people knowledgeable in
implementing and deploying solutions based on these protocols.
14.
15. TCP/IP
The TCP/IP networking protocol stack serves as the base on which the rest of the
UPnP protocols are built.
UPnP devices can use many of the protocols in the TCP/IP stack including TCP,
UDP, IGMP, ARP and IP as well as TCP/IP services such as DHCP and DNS.
Since TCP/IP is one of the most ubiquitous networking protocols, locating or
creating an implementation for a UPnP device that is tuned for footprint and/or
performance is relatively easy.
16. HTTP, HTTPU, HTTPMU
HTTP, which is hugely responsible for the success of the Internet, is also a core
part of UPnP.
All aspects of UPnP build on top of HTTP or its variants.
HTTPU (and HTTPMU) are variants of HTTP defined to deliver messages on top
of UDP/IP instead of TCP/IP.
GENA
Generic Event Notification Architecture (GENA) was defined to provide the ability to
send and receive notifications using HTTP over TCP/IP and multicast UDP.
17. SSDP
Simple Service Discovery Protocol (SSDP), as the name implies, defines how
network services can be discovered on the network.
SSDP is built on HTTPU and HTTPMU and defines methods both for a control
point to locate resources of interest on the network, and for devices to
announce their availability on the network.
By defining the use of both search requests and presence announcements,
SSDP eliminates the overhead that would be necessary if only one of these
mechanisms is used
As a result, every control point on the network has complete information on
network state while keeping network traffic low.
A UPnP control point, upon booting up, can send an SSDP search request (over
HTTPMU), to discover devices and services that are available on the network.
18. SOAP
Simple Object Access Protocol (SOAP) defines the use of Extensible Markup
Language (XML) and HTTP to execute remote procedure calls.
It is becoming the standard for RPC based communication over the Internet.
By making use of the Internet’s existing infrastructure, it can work effectively with
firewalls and proxies.
Each UPnP control request is a SOAP message that contains the action to invoke
along with a set of parameters.
20. Addressing
The foundation for UPnP networking is the TCP/IP protocol suite and the key to
this suite is addressing.
Each device must have a Dynamic Host Configuration Protocol (DHCP) client
and search for a DHCP server when the device is first connected to the
network.
If a DHCP server is available, the device must use the IP address assigned
to it.
A device may implement higher layer protocols outside of UPnP that use friendly
names for devices
In these cases, it becomes necessary to resolve friendly host (device) names
to IP address
Domain Name Services (DNS) are usually used for this.
21. Discovery
Once devices are attached to the network and addressed appropriately,
discovery can take place.
When a device is added to the network, SSDP allows that device to
advertise its services to control points on the network.
When a control point is added to the network, SSDP allows that control
point to search for devices of interest on the network.
The fundamental exchange in both cases is a discovery message
containing a few, essential specifics about the device or one of its services,
for example its type, identifier, and a pointer to its XML device description
document.
22. Description
After a control point has discovered a device, the control point still knows
very little about the device.
For the control point to learn more about the device and its capabilities, or to
interact with the device, the control point must retrieve the device's
description from the URL provided by the device in the discovery message.
The UPnP description for a device is expressed in XML and includes vendorspecific, manufacturer information including the
model name and number,
serial number,
manufacturer name,
URLs to vendor-specific Web sites,
23. Control
To control a device, a control point sends an action request to a device's
service.
To do this, a control point sends a suitable control message to the control
URL for the service (provided in the device description).
Control messages are also expressed in XML using SOAP.
In response to the control message, the service returns action specific
values or fault codes
24. Eventing
A UPnP description for a service includes a list of actions the service
responds to and a list of variables that model the state of the service at
run time.
The service publishes updates when these variables change, and a control
point may subscribe to receive this information.
Event messages contain the names of one of more state variables and the
current value of those variables.
These messages are also expressed in XML and formatted using GENA.
25. Presentation
If a device has a URL for presentation, then the control point can retrieve
a page from this URL, load the page into a browser, and depending on
the capabilities of the page, allow a user to control the device and/or
view device status.
27. The scope of UPnP is large enough to encompass many existing, as well as
new and exciting scenarios including home automation, printing and
imaging, audio/video entertainment, kitchen appliances, automobile
networks, and proximity networks in public venues.
28. Universal Plug and Play (UPnP) is a set of networking protocols that permits
networked devices
Universal Plug and Play is an open initiative to take existing standards, existing
technologies and existing knowledge, re-purpose it, and deliver on the promise
and opportunity of the networked world.
Standards-based, simple enough for the smallest appliances to implement,
powerful enough to scale to the global Internet, and based on the proven
approach of Internet protocols.
Universal Plug and Play is an incremental approach, but an approach that has
been proven to work.
