Using ICN to simplify data delivery, mobility management and secure transmissionITU
ICN provides a unified network and transport layer addressing content by name rather than by location. By disrupting traditional connection-oriented communication model, ICN simplifies data delivery, mobility management and secure transmission over an heterogeneous network access. In the demo, we select DASH video delivery as use case and show the benefits of ICN mobility management, in-network control (rate/loss) and network-assisted bitrate adaptation for a multi-homed user device.
We also illustrate how ICN can effectively reduce transport cost via native edge caching and multi-point/multi-source communications over the backhaul. To that aim, we orchestrate an ICN-enhanced virtualized network backhaul and shows its utilization over time.

3GPP Packet Core Towards 5G Communication SystemsOfinno
This presentation provides an overview of 3GPP packet core and 5G systems. Some enabler features are outlined, such as network slicing. This presentation was prepared for the 20th Annual International Conference on Next Generation Internet and Related Technologies Net-Centric 2017 that was held at George Mason University.
Towards a 5G Operating Platform Infrastructure-agnostic OrchestrationITU
This presentation and demo will show an overarching orchestration software architecture that is based on a continuous advertisement of capabilities and resources from underlying infrastructure-layer domains, which allows the orchestration to adapt its service logic to exploit the most up-to-date capabilities. The feasibility will be shown to setup a complex NFV service across multiple domains, such as two OpenStack instances connected by an SDN network, where all the service functions (e.g. NAT, firewall, etc.) are launched in the datacenter and the intermediate SDN network is used only to connect all the different components together. However, when the SDN network advertises also the capability to host a given set of network applications (e.g. a NAT), the orchestrator will adapt its service logic and it will instantiate part of the service in the datacenter (e.g. as virtual machines), part in the SDN domain (e.g. as ONOS applications), hence enabling more aggressive optimization strategies in the overarching orchestrator.

These slides explain the Protocol Framework for 5G mmWave Backhaul Network, as a part of a project presentation for the course Telecom Architecture at Northeastern University.
This presentation and demo show the hardware which consist of 5G UE’s, 5G radios, a fronthaul network and C-RAN with high density switches and servers, a transport network of 3 DWDM switches and a DC network of servers and high density switches. The basic software arrangement will be shown with emphasis on the structure of the orchestration and SDN controllers and the choice of virtualization components and logical networking. An eMBB slice will be brought up which will entail programming of the radios, the fronthaul, backhaul, a node B and the core. Its behavior will be noted through the test UE’s. An URRLC slice will be brought up and its nodeB and core will be demonstrated through its test UE’s showing extremely low latency. An MMTC slice will be brought up and a large number of test IOT devices will be demonstrated via the test UE’s. The eMBB slice will be augmented by programming a slice selection function that will create a ICN slice and an application (TBD) will be shown running over that ICN core (but with the eMBB slice). Spectrum will be reassigned from slice to slice and the changes noted as an optimizer recomputes the proper allocation of resources and executes it. Traffic will be increased and the changes in the backhaul over transport and core function placements will be noted. An additional demonstration will show creation of multiple 4G air interfaces using the same infrastructure network but with 4G radios and 4G UE’s using OAI software and ETTUS SDRs. A Skype session will be created between the two 4G slices. We will also try to show some of the EPC functions being moved while the UE sessions are not impacted.

Presented by Michael Gronovius, Director Business Development, Ericsson
5G Technology is based on three pillars. Let's discuss the basic ideas of all three concepts of 5G and details about URLCC workflow.
The specifications of 5G NR in Standalone operation are due for completion in June 2018, which will provide a complete set of specifications for the 5G Core Network that goes beyond Non-Standalone. The ‘full’ 5G System includes:
eMBB (enhanced Mobile Broadband)
URLLC (Ultra Reliable Low Latency Communications)
mMTC (massive Machine Type Communications)
The initial phase of 5G Non-Standalone deployments focuses on eMBB, which provides greater data-bandwidth complemented by moderate latency improvements on both 5G NR and 4G LTE. This will help to develop today’s mobile broadband use cases such as emerging AR/VR media and applications, UltraHD or 360-degree streaming video and many more.
mMTC has been already developed as part of 3GPP Release 13/14 low power wide area (LPWA) technologies, which includes NB-IoT. These are expected to meet most 5G mMTC requirements, while others that require more bandwidth with ultra-reliable low latency (full URLLC) will require the 5G Core deployment for full end-2-end latency reduction. Mission critical applications that are especially latency-sensitive will also require wide coverage, which is highly unlikely in early 5G deployments, so this development will come later.
MediaTek continues to heavily invest in the development of 5G products and is committed to accelerating its adoption. Our intention is to bring technology to the mid-tier market from day one in accordance with our brand philosophy. This contrasts with the usual premium-first approach the rest of the industry often focuses on, and we believe we can offer a unique and powerful platform.

NGFI (Next Generation Fronthaul Interface) native RoE (Radio over Ethernet)ITU
This is a presentation and a demo for both NGFI (Next Generation Fronthaul Interface) native RoE (Radio over Ethernet) with Intra PHY split implemented in it, and CPRI over Ethernet encapsulated in structure agnostic mode. Compared to CPRI, the NGFI native RoE implementation improves bandwidth usage greatly, which better supports 5G applications demanding for higher bandwidth. In the CPRI over Ethernet demonstration, bidirectional CPRI flows are recovered without error, which enables C-RAN (centralized radio access network) architecture by using Ethernet as a transport network.

Time is everywhere but it's implementation in #5G is not easy. Unlike #4G, #TDD is more common in 5G especially in mid-bands [ #3.5Ghz (CBRS) and #Sub6Ghz ] to higher bands (as in mmWave) spectrums and also in spectrum overlays. TDD provides #spectrum efficiency but requires precision time synchronization.

Introduction to FG IMT-2020 network softwarization work and demo of softwariz...ITU
The presentation and demo shows how to slice eNodeB (eNB) and Evolved Packet Core (EPC) on our FLARE node, highly programmable network node, as proof of concept of network softwarization and network slicing for IMT-2020. In our PoC demo, we softwarize both eNB and EPC using modified OpenAirInterface and implement LTE network in a slice on top of a FLARE node, where signaling related EPC entities (e.g., MME) and eNB is implemented in a control-plane while user data forwarding and processing (e.g., SGW and PGW) is implemented in a data plane. In the data plane, we divide EPC into function elements and parallelize packet processing across on-chip many core processors. FLARE enables rapid deployment of data plane network functions with Click network-programming framework. In the control plane, we run signaling-related EPC, eNB and HSS in Docker instances within the same FLARE slice. Each LTE network slice is Dockerized (implemented in Docker), i.e., in minimal resource environment. LTE network slice instances are isolated without interfering one another. We demonstrate play back of YouTube movies on a smart phone (Nexus 5) connected to an OAI slice on FLARE.

Secure and Service-Oriented Network Control Framework for WiMAX Networks
IEEE 802.16 supports both TDD ( time-division duplex) and FDD (frequency-division duplex)
Multihop communication is needed for deployment of wimax network. Because of multihop
Security is issues associated with wimax network
Issue is how to support different services and applications in WiMAX networks
Adaptive Source Provision System (ASPS) for
Proficient Freight Complementary in WiMAX
Network
Today in the wireless network field, WiMAX
(Worldwide Interoperability for Microwave access) has
emerged out as one of the promising networking
technologies. In order to compete with the existing wireless
technologies like Wi-Fi and Bluetooth (IEEE 802.15),
WiMAX has to promise cost efficiency and better quality of
service (QoS). The Adaptive source provision system is
proposed to control traffic rate and ensure load balancing in
the WiMAX network. The proposed approach considers
relay station in the network. When there is an arrival of new
users in the network, its data rate is computed and then
compared with the data rate of RS. When the data rate of
new user is less than that of RS, then the data rate of the
corresponding base station is compared. The connections
are switched from congested stations to non-congested
stations to minimize network load. The handover mechanism
is used by BSs for optimally balancing the traffic load within
the network. LB-based handover mechanism guarantee
user’s QoS and evenly distributes the traffic load. The
experimental analysis showed that the proposed method
achieves better traffic management and load balancing
when compared with the existing approaches.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

12. SFA & SFM model(2/2)
• WiMAX network model consists of CSN
(Connectivity Service Network) 、 ASN (Access
Service Network) and User terminal 。
• CSN contains Application server 、 Strategy
agent and AAA server 。 ASN contains
SFA(Service Flow Authorization) and
SFM(Service Flow management) 。
• QoS is handled by the Strategy agent of CSN
and Strategy server of ASN , and using
DiffServ to support QoS 。
16. Loose Interworking model
• Loose couple and existing networks; Wimax
utilizes the AAA server of 3GPP network, and
data streams are not passed through the core
network of 3GPP. This method guarantees the
independence of Wimax network, how-ever, it
results in high handover latency between two
networks 。
• The handover between WLAN and UMTS was
researched, and the average handover latency
results for loose couple and tight couple are
400ms and 150ms, respectively. Therefore, it is
not suitable for real-time services 。
17. Tight Interworking model
• In tight couple mode, the data streams of Wimax
must pass through the RNC (Radio Network
Controller) and the core network of 3GPP, so
each of the existing networks must modify their
protocols, interfaces, and services to meet the
requirements of interworking. The BS of Wimax
connects with RNC of WCDMA or SGSN
directly.
• The advantage of this mode is that it reduces the
handoff latency and guarantees seamless
handoff. If different operators own both 3G and
Wimax networks, the integration would be
troublesome for the open of networkinterface.
18. QoS GUARANTEE
• UMTS defines four classes of QoS services
based on different application requirements:
conversational, streaming, interactive, and
background.
• Wimax also defines four classes of QoS: UGS
(unsolicited grant service), realtime polling
service (rt-PS), non-real-time polling service (nrt-
PS) and BE (best effort).
19. QoS Mapping
• The conversational and streaming services of
UMTS correspond to the UGS and rt-PS
services in Wimax.
• The interactive service can be mapped to nrt-PS
and BE services in Wimax in different application
scenarios.
• The background service in UMTS has the same
requirement and
• Application scenario as the BE service in Wimax
27. Summary and Outlook
• In summary, SIP is the key signaling protocol of IMS. Interworking
between SIP elements of the Wimax and CSCFs of the IMS is a key
issue in reaching a high level of interworking between Wimax and
3GPP networks.
• The overall architecture of the interworking based on IMS is
represented, as well as special issues such as QoS guarantees and
AAA problems are discussed.
• Some additional considerations are required in further study, such
as:
– Network detection and selection: after the MS detects the available
ASNs and corresponding CSN in a given area, the selection of the
PLMN is done according to TS 23.234.
– Wimax provides powerful and flexible QoS handling which cannot be
fully utilized within the current 3GPP-WLAN interworking specification.
– Handoff capability from 3GPP network to Wimax network is usually
referred to as level 4 (intersystem mobility) and 5 (seamless intersystem
mobility). These levels are beyond the scope of the recent releases, but
they will be addressed in future releases. The last three levels represent
network convergence.
