The article presents an analysis of the problem of correct network interaction, based on BGP routing protocol. It analyzes the main attacks on information systems, due to the use of this protocol. Scenario of typical attack is presented. Basic measures to prevent information security threats when using the BGP protocol are offered.
A key aspect of realizing the future smart grid communication solution is a balanced approach between the network performance and the network security during the network deployment. A high security communication flow path is not useful when the network path cannot support capacity and reachability requirements. The deployment phase in communication network can facilitate an optimal network path by...
In challenged networks, such as opportunistic networks or Delay Tolerant Networks (DTNs), due to frequent network partition an end-to-end connection between source and destination may not always be possible due to nodes move unpredictably with high speeds. For such type of networks, traditional routing protocols fails to transmit and also no guarantee on delivery of data to specified destination because...
The smart grid (SG) is widely acknowledged asthe new solution to be developed to handle distributed network fighting against the increase of renewable energy. Wireless Sensor Networks (WSNs) have been extensively recognized as a promising technology that can improve various aspects of electrical models today as smart grid. Hence, WSNs are well suited for applications based on this type of communication...
Delay Tolerant Network (DTN) shows some features like link frequent interruptions, long delays, limited resources and so on, while nodes fight each other to win the network resources in the process of communication, which can lead to network congestion in delay tolerant network. Therefore, congestion control is a key issue in delay tolerant network research. The present congestion control strategies...
The Internet is inherently a multipath network: For an underlying network with only a single path, connecting various nodes would have been debilitatingly fragile. Unfortunately, traditional Internet technologies have been designed around the restrictive assumption of a single working path between a source and a destination. The lack of native multipath support constrains network performance even...
Considering the modern internet traffic rates, the network architecture is of particular importance as the running services itself. On the other hand, due to the increasing complexity and black-box structure of the available networking hardware (switches, routers, etc.), the necessary network innovation imposed by the running services becomes infeasible in practice. The software-defined networking...
Routing is the process of selecting path in a network along which to send network traffic. Routing is performed for many kinds of network, including the telephone network, electronic data networks, and transportation networks. it involves two basic activities: Determining best path and forwarding packets through these paths. The internet routes packet one at a time, some of these packets may be delayed...
Multi-path routing is a promising technique to increase the Internet's reliability and to give users greater control over the service they receive. Currently the interdomain routing protocol limits each router to using a single route for same destination, which may not satisfy the diverse requirements of end users. In this paper, in order to support the effective and efficient multi-path service(MPS),...
Network reliability is needed as the Internet becomes an important social infrastructure. However, we face risks of failure and congestion on many links or routers, therefore, a network should be robust enough to avoid failure and congestion. As the route of a path between two nodes is automatically determined by a routing protocol, many paths may be included in a same link and it may cause congestion...
Site-multihoming is an architecture which brings the benefit of reliability and load-sharing in a small scale network like a home network by connecting multiple ISPs (Internet Service Providers). In the discussion of IETF Multi6 Working Group, multihoming by multi-PA (Provider Aggregatable) addressing became rough consensus as the architecture for IPv6 site-multihoming. However, issues on multi-PA...
Protocols such as 6LoWPAN will soon directly connect the Internet to the rapidly growing number of deployed Low Power and Lossy Networks (L2Ns). The outcome will enable many novel applications, including new types of Cyber-Physical Systems, the “Internet-of-Thing”, the Smart Grid, etc. Due to resource constraints the performance of a L2N routing protocol is quite sensitive to changes in protocol parameters...
Providing Internet access on buses allow people to read news, check emails, watch sport games, and hence can greatly improve the quality of people's life. This paper proposes an adaptive routing protocol, called R-BUS for a bus network. R-BUS selects a route based on the link's lifetime and its communication signal quality. The protocol takes the bus mobility and the radio propagation model into account...
Network virtualization is becoming an irresistible trend for building future Internet. It enables multiple virtual networks running on the same physical substrate, by which network service can be deployed on a customized virtual network to get better performance. In this paper, we propose a method to achieve more reliable live streaming service by deploying it over multiple virtual networks, namely...
In this paper I propose an approach to retrofit delay and disruption tolerance directly into the Internet Protocol. I discuss the benefits, limitations, and architectural implications - within the context of end-to-end arguments for the Internet and secure IP-based black core networks - of this retrofit.
In the job by me substantive provisions of the protocol of external gateway BGP4 are considered. Alongside with it the basic advantages of the protocol have been revealed and the provisional organization of a backbone with use BGP4 is shown.
As more and more mission critical services emerge on the Internet, there is a growing demand for the Internet to provide stringent service availability and reliability. More and more domains adopt multi-homed connection to expect increasing reliability. But the de facto inter-domain protocol - BGP spends a long period to converge to another stable state when one of the links of multi-homed domain...
Maintaining connectivity is a key responsibility of any routing system, but successfully carrying it out can be challenging, especially for inter-domain paths. Many measurements indicate the links failures are fairly common in the Internet. During the period of failures, some destination would be unreachable and the corresponding services unavailable. Shrinking the convergence time window to improve...
As the Internet becomes the critical information infrastructure for both personal and business applications, fast and reliable routing protocols need to be designed to maintain the performance of those applications in the presence of failures. Today's interdomain routing protocol, BGP, is known to be slow in reacting and recovering from network failures. Increasing path diversity by advertising multiple...
The policy-oriented nature ofBGP provides network operators with great flexibility and control over the interdomain routing, nevertheless researchers showed that these benefits come at the cost of stability and predictability. In particular, policy interactions often separate, both in time and space, the effects of network events from their causes, making it hard to assess and debug network configurations...
