Current Trends in Using the Software-Defined WAN
No full textThe given work is devoted to the investigation the current trends of using the Software-defined WAN as a specific application of software-defined networking technology applied to WAN connections such as broadband internet, 4G, LTE, or MPLS. While connecting enterprise networks – including branch offices and data centers – over large geographic distances, SD-WAN simplifies the management and operation of a WAN by separating the networking hardware from its control mechanism
WAN-in-Lab: motivation, deployment and experiments
No full textWAN-in-Lab is a hardware testbed for the design, development, testing and evaluation of high speed network protocols. It uses real carrier-class networking hardware to avoid the artifacts introduced by network simulation and emulation, while being localized to allow detailed measurement of network performance. WAN-in-Lab is an open resource, available for use by the networking community. This paper describes the structure of WAN-in-Lab and the rationale behind it, issues encountered, and experimental results that illustrate its applications

Proposed New SD-WAN Architecture to Facilitate Dynamic Load Balancing
No full textSD-WAN (Software Defined Wide Area Networking) is widely regarded as the future of networking as it integrates programmable features into its architecture. However, there is currently no all-encompassing solution for traffic monitoring policies in the control plane that accounts for the dynamic behaviour of applications transported in the SD-WAN architecture. In a traditional SD-WAN controller configuration, load balancing is distributed across different WANs according to predefined policies. Furthermore, existing SD-WAN controllers do not account for the effect of load balancing on end-to-end protocol performance and vice versa. To address this gap, this study proposes a new logical SD-WAN architecture to facilitate dynamic load balancing of end-to-end protocol operations in the SD-WAN architecture for improved resource utilisation. This is achieved through interaction between the Enhanced SD-WAN controller's traffic management decisions system and end-to-end protocol performance, which requires deep packet inspection of network data flows to detect signs of congestion. The solution involves developing a traffic monitor function which is responsible for analysing, classifying, and managing traffic. Additionally, an enhanced SD-WAN controller called “En-SDWAN controller” focuses on sending route updates to edge routers to change the route of traffic flows that are experiencing congestion is implemented. The performance of the developed Enhanced SD-WAN architecture was assessed in reference to the traditional SD-WAN across various scenarios, including regular traffic, link failure, and when network congestion is experienced. In the normal traffic conditions, the performance of Enhanced SD-WAN closely resembles that of traditional SD-WAN, owing to the absence of congestion within the network architecture. The average throughput performance of Enhanced SD-WAN stands at 50.07%, while traditional SD-WAN operates at 49.93%. However, during network link failures, Enhanced SD-WAN demonstrates quicker convergence and better throughput performance compared to traditional SD-WAN by 1.46%. Similarly, during instances of network congestion, Enhanced SD-WAN exhibits an average throughput of 11.21Mbps, surpassing traditional SD-WAN's average throughput of 7.02Mbps. The implementation of both the GNS3 and Python applications validates the results and design, demonstrating consistency throughout. This outcome underscores the improved flow control of packets facilitated by route updates and dynamic load sharing implemented within the Enhanced SD-WAN controller. The implementation of a new logical architecture has enhanced the performance and efficiency of traditional SD-WAN systems by adapting to the evolving nature of applications and offering better control over network traffic
Faces and Places in Fashion: Jeff Wan

Chinese literary works translated into Baba Malay: a bibliographical study
No full textAnalyses 68 unique titles of Baba translated works published between 1889 and 1950. The titles are held in the libraries of the University of Malaya (UM), Science University Malaysia (USM), National University of Malaysia (UKM), the Dewan Bahasa dan Pustaka (DBP), National University of Singapore (NUS), National Library of Singapore (NLS) and the British Library (BL). The results reveal three periods of active publication of Baba translated works. A total of 18 works were translated before World War I, followed by 10 just after the war, 39 titles were published before the break of the World War II and 1 was identified in 1950. There were 103 persons involved in the 68 translated works, some of whom are responsible for more than one title. The most prominent translators were Chan Kim Boon, Wan Boon Seng, Seow Chin San and Lee Seng Poh. Some of the translators were also be editors, illustrators or editors. There were 31 publishers and 21 printing presses involved, all were located in Singapore. The most active publishers were Wan Boon Seng, Kim Seck Chy Press and Nanyang Romanised Malay Book Co. The translated works mainly cover historical classical Chinese stories, chivalrous stories, romances, folklore and legends. The titles were priced between 10 cents to 2 dollars in Straits currency. The University of Malaya Library held the largest number of unique title (62) out of which 15 were unique titles
Logically Isolated Group Network for Virtual Convergence Environment over SD-WAN
No full textSoftware-defined Wide Area Network (SD-WAN) is gaining strong momentum as distributed cloud evolves. The new cloud infrastructure requires novel and innovative network technologies based on virtualization, automated resource (e.g. datacenters, VMs, networks) convergence, ultra-high data forwarding performance, and strict network security. To meet the demands, this paper suggests a scheme for logically isolated group network for virtual convergence environment and evaluates its performance in terms of virtual network generation over the de-facto SD-WAN infrastructure deployed on the advanced research network (KREONET), which operates in six distant cities in Korea and the USA
