As an essential part of smart grid, the demand for smart distribution grid has changed greatly with the access of distributed energy, electric vehicles. This paper analyzes all sorts of communication service demand for smart distribution grid, presents a distribution grid network service classification optimizing management scheme based on business sense, which uses business identification and classification...
The naming and routing schemes in traditional TCP/IP were designed in the days when processors were slow and memory was expensive. These schemes are weak in terms of the following aspects: inability to properly support mobility and multi-homing, creating complexity in the network configuration, making network measurement difficult, and so on. To avoid such weaknesses, we propose a new naming and routing...
Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol. There have been many incidents of IP prefix hijacking by BGP protocol in the Internet. Attacks may hijack victim's address space to disrupt network services or perpetrate malicious activities such as spamming and DoS attacks without disclosing identity. The relation on prefix hijacking and the Internet hierarchy is presented...
As the network technology and applications continue to evolve, computer networks become more and more important. However, network users can attack the network infrastructure (such as domain name service and routing services, etc.). The networks can not provide the minimum required quality of service for control. Network situation can not be aware in a timely manner. And network maintaining and upgrading...
The wireless ad hoc networks (WANET) is an open system that is constituted by fix or mobile nodes. In WANET, each node can be a router or a host. Considering that most nodes may use battery as its energy, it is necessary to improve on energy-saving method. Based on the MAODV protocol, we bring forward a new method called PPEF that uses both hops and energy consumption level of each node together for...
IP routing protocols, such as OSPF (open shortest path first) or BGP (border gateway protocol), have many configurable parameters (e.g., timers) and interact with each other in complex ways. Network operators may need to explore numerous candidate configuration changes before identifying a choice. In this paper, from the point of view of the economics of the Internet backbone, we propose a potential...
This paper analyzes the relationship between BGP convergence and the power-law of the Internet. The inter-domain routing system is classified into three hierarchies based on the power-law and commercial relations of autonomous systems. The relation of network topology and three convergence parameters-convergence time T, affected ASs set Nc and affected paths factor mu is presented for all sorts of...
This paper presents an optimization mechanism to facilitate efficient selection of BGP egress for an AS, when IGP link state changes. Most mechanisms for BGP egress selection have primarily focused on achieving an optimized goal by considering it as a static problem, which leads to inflexibility to variations in the topology of an AS, especially for link failures which often occur in an AS network...
Hot-potato routing is a mechanism employed in the border gateway protocol (BGP), when the BGP selects the interdomain egress with the closest egress point based on intradomain path costs. Recent work has shown that it can impact the robustness of interdomain routing especially for large ISP backbones. Some mechanisms have been proposed to replace the hot-potato routing such as interdomain traffic...
