In this paper, the authors' primary focus lies in enhancing the #Quality #of #Service (#QoS) of #Vehicle-#to-#everything (#V2X) applications utilizing #Open #Radio #Access #Network (#O-#RAN) architecture. To this end, they propose a novel optimization framework that creates dynamic RAN slicing covering tailored functional split selection per slice, and #Multi-#access #Edge #Computing (#MEC) server placement within O-RAN architecture. In addition, #Packet #Duplication (#PD) techniques are used in the proposed work to enhance V2X application reliability. First, they define the proposed problem as convex and linear, and then they use Benders a distributed technique that accelerates performance while ensuring the global optimal solution. The approach is validated through simulations, which demonstrate its capability to meet the QoS requirements of V2X applications and outperform existing methods. According to the results, there is a trade-off between the achieved throughput and the extra overhead due to replicated packets which incurs extra resources such as radio and computation to the network. ---- Behnam Ojaghi, Ferran Adelantado, Christos Verikoukis More details can be found at this link: https://lnkd.in/en2quGHa

The present work presents a novel combination of #TCP and #backpressure #at #the #network #layer, overcoming any compatibility issues and allowing for backpressure to be active at all network nodes without exceptions. The key idea is to apply the #Lyapunov #framework cumulatively, over a large set of router hardware clock ticks. This approach allows for the throughput-optimal backpressure decisions to be expressed via regular traffic engineering routing rules, instead of explicit per-packet forwarding directives. ---- Liaskos Christos, Konstantinos Alexandris, Anindya Das, Siyu Tang, Leandros Tassiulas More details can be found at this link: https://lnkd.in/ebWSihV8

We are back at work and developing new and exciting features for our Switch/Router IPs. The following features has now been added to our IP: - Ability to store packet data in DRAM. This allows a design on certain ports/queues to have a external spill over buffer and store this in DRAM when the internal SRAM is not large enough. - Hierarical QoS Scheduler. This allows a customer to have up to 6 levels of scheduler and the scheduler order is defined by software, each level has their own shapers. - IP-in-IP translation. Our packet processing now understand and allows a routed packets to enter/exit in IPvX-over-IPvY networks without having to re-circulate the packet multiple times. IP headers can be be both added and removed allowing the router to enter into IP tunnels and exit from IP tunnels. ... What is the next feature you want in your next switch/router IP?

Understanding OSPF Virtual Links OSPF (Open Shortest Path First) virtual links extend Area 0 through a transit area when direct connectivity isn’t possible, ensuring all areas remain connected to the backbone. ➤ How Virtual Links Work • Virtual links create a logical path through the transit area, ensuring connectivity to Area 0. • Virtual links are configured between Area Border Routers (ABRs) in a transit area that acts as a bridge between the non-backbone area and Area 0. • The transit area cannot be a stub area or NSSA (Not-So-Stubby Area) because these types of areas do not allow virtual links. ➤ When to Use Virtual Links • When a non-backbone area needs to connect to Area 0 indirectly via a transit area. • When a network’s backbone (Area 0) becomes split, and connectivity to Area 0 needs to be restored. • Virtual links should be a short-term solution to address sudden design issues, such as when direct connectivity to Area 0 isn’t possible. While virtual links can be a helpful temporary fix, they add complexity and should only be used when necessary. Whenever possible, it’s better to establish direct connections to Area 0 in your OSPF network.

The OSI (Open Systems Interconnection) Model is a conceptual framework that standardizes communication functions of a telecommunication or computing system. This model serves as a guide for understanding and designing network interactions, consistency and compatibility across technologies.

This paper identifies #transmission #scheduling at the #RAN #level as a significant contributor to end-to-end latency when considering network slicing. In this direction, they propose a #two-#level #MAC #scheduling framework that can effectively #handle #uplink and #downlink transmissions of network slices of different characteristics over a shared RAN, applying different per-slice scheduling policies, and focusing on reducing latency for URLLC services.----Adlen Ksentini, @Pantelis Frangoudis, Amogh PC, Navid Nikaein More details can be found at this link: https://lnkd.in/g4jSY-fd

Need to ensure your base station is up to the task? Learn how in this demo: https://gag.gl/9WhQs3? The PathWave 89600 VSA software provides robust support to #3GPP features using its #5G New Radio measurement application. The 89600 VSA software’s 3D traces show #EVM by power per symbol and per subcarrier. These traces are useful when verifying base station systems to ensure the power per each resource element is balanced. The software also allows for decoding of the signal and getting cyclic redundancy check (CRC) information if the transmitted signal has channel coding. #NewRadio #SignalAnalysis #RedCap #Technology
