“…Hence, Network slicing and traffic shaping for guaranteed end-to-end QoS [3] are evolving to address these diverging performance requirements that many verticals impose in terms of latency, scalability, availability, and reliability. The increasing demand for QoS requirements due to the emerging services has led to various network-layer mechanisms' evolution for cellular (5G QoS Identifier) [4] and internet (Traffic Class/Type of Service) [5] models. 5QI is a mechanism standardized by the 3GPP cellular network to classify packets into different QoS classes.…”

As the 5G systems have introduced network slicing on the virtualized network environment, application-specific QoS (Quality of Service) management has come to the fore to support a range of services, such as eMBB (enhanced Mobile Broadband), URLLC (Ultra-Reliable Low Latency Communications), and mIoT (massive Internet of Things). It is expected for the next-generation systems to support more diverse applications demanding newer and granular quality characteristics for network services. Most of the current transport layer protocols, built on layering design and best-effort paradigm, do not provide the necessary precision and adaptability required for various QoS support. Therefore, we need new protocols that comprehend application behaviours and adapt to dynamic network conditions for more fine-grained QoS enhancement. This paper presents a Context-oriented Transport (CoT) layer for the next-generation network that understands the application context and adapts to varying network conditions with flowbased QoS control. CoT is an end-to-end software solution that improves the underlying network capacity utilization and prioritizes the traffic flows according to quality needs. We prototyped CoT in Linux/Android devices and evaluated the performance with emulated traffic environment. The experiments show that CoT reduces latency by up to 16.5% and improves average throughput by up to 30%, compared with Android 10 in LTE network, resulting from enhanced traffic classification and network utilization.

“…IPv4 includes no quality of service mechanisms: IPv6 adds support for Quality of Service (QoS) mechanisms through the use of flow control bits; these will enable routers to prioritise packets based upon QoS considerations and economise storage by aggregating routing tables [5].…”

IPv4 addressing space has almost been exhausted;many organisations will soon be required to perform thechangeover to IPv6. Traditional IPv4 routing protocols must bereplaced with new IPv6 compatible protocols to ensure systemscontinue to operate effectively; however these protocols haveundergone significant changes in order to support IPv6.Understanding these changes is important when selecting arouting protocol for a system, in order to facilitate this, a studyand comparison of two popular routing protocols; OSPF andEIGRP has been undertaken. The major changes between theIPv4 and IPv6 editions have been identified and discussed andthe two protocols have been compared against a number ofcriteri
