We demonstrate the practical implementation of a schema for Smart Grid Last Mile (SGLM) traffic management in leased Internet access networks, based on well-known queue management and traffic marking algorithms such as Random Early Drop and Token Bucket. Internet access links are often over-provisioned, with much higher installed capacity than user needs, so domestic applications do not compete for...
Supporting guaranteed QoS is a significant issue in packet transport networks. Since various services require their own quality of service, flow-based traffic management that properly controls network resources when traffic congestion occurs is required for network nodes. In this paper, we propose an integrated flow management scheme to support guaranteed QoS in packet transport systems that comprise...
This paper proposes a topology-based hierarchical scheduling scheme using deficit round robin (DRR). The main idea of the topology-based hierarchical scheduling is to map the topology of the connected network into the logical structure of the scheduler, and combine several token schedulers according to the topology. The mapping process could be completed through the network management plane or by...
Carrier Ethernet is becoming a favorable access technology for next generation network (NGN). The features of cost-efficiency, operation flexibility and high bandwidth have a great attraction to service providers. However, to achieve these characteristics, Carrier Ethernet needs to have quality of service (QoS) provisioning abilities, which guarantee end-to-end performances of voice, video and data...
The application of wireless sensor mesh networks in Intelligent Transportation System (ITS) is presented in this paper. For a short distance transmission, the data collector collects data from Reduced Function Device (RFD) sensors node using an efficient wireless network based on Zigbee technology. A mesh sensor network is suggested instead of traditional start network. The time needed to collect...
Day by day Internet communication and services are experiencing an increase in variety and quantity in their capacity and demand. Thus, making traffic management and quality of service approaches for optimization of the Internet become a challenging area of research; meanwhile flow control and congestion control will be considered as significant fundamentals for the traffic control especially on the...
Ethernet is one of the potential candidates capable of meeting the bandwidth demands of subscribers and successfully supporting various services in broadband access networks. However, the lack of a traffic management capability is a major obstacle to successful deployment. In this article we suggest an Ethernet switch architecture that offers performance-guaranteed broadband access services. We also...
Ethernet protocol is the most wide-spread protocol in the local area network (LAN) environment. It is cost effective, simple, and provides high speeds, exactly what is needed in the provider network. However, deployment in the provider network imposes carrier-grade requirements. Standardization bodies realized this, and they are extending its capabilities: QoS support and traffic management by 802...
