“…We chose to measure IP anycast use ourselves rather than use on publicly available data. While a public anycast census exists [22], it lacks IPv6 information. Regarding geolocation, the iGreedy measurement mechanics offer the means to determine this for anycast IP addresses.…”

Electronic government (e-gov) enables citizens and residents to digitally interact with their government via the Internet. Underpinning these services is the Internet Domain Name Systems (DNS), which maps e-gov domain names to Internet addresses. Structuring DNS with multiple levels of redundancy that can withstand stress events such as denial-ofservice (DoS) attacks is a challenging task. While the operator community has established best practices to this end, adopting them all involves expert knowledge and resources. In this work, we obtain and study a list of e-gov domain names used by four countries (The Netherlands, Sweden, Switzerland, and the United States) and measure the DNS structuring of these domains. We show the adoption of best practices, inter-country differences, and provide recommendations for improve DNS service robustness.

“…Anycasting is supported by both versions 4 and 6 of the Internet Protocol (IP) as documented in RFCs 1546 and 4291, and the Border Gateway Protocol (BGP-4, RFC 4271). It plays a vital role for DNS and CDN and services, but different issues have been noted, including the detection latency of IP anycast prefixes [20], AS-level anycast path inflation [21], and client-server mapping limitations that arise in CDN routing [2]. Several enhancements have been discussed focusing on either performance, see, e.g., [22,23], or security, e.g., to mitigate distributed denial-of-service (DDoS) attacks [5].…”

A Cognitive Anycast Routing Method for Delay-Tolerant Networks

A cognitive networking approach to the anycast routing problem for delay-tolerant networking (DTN) is proposed. The method is suitable for the space–ground and other domains where communications are recurrently challenged by diverse link impairments, including long propagation delays, communication asymmetry, and lengthy disruptions. The proposed method delivers data bundles achieving low delays by avoiding, whenever possible, link congestion and long wait times for contacts to become active, and without the need of duplicating data bundles. Network gateways use a spiking neural network (SNN) to decide the optimal outbound link for each bundle. The SNN is regularly updated to reflect the expected cost of the routing decisions, which helps to fine-tune future decisions. The method is decentralized and selects both the anycast group member to be used as the sink and the path to reach that node. A series of experiments were carried out on a network testbed to evaluate the method. The results demonstrate its performance advantage over unicast routing, as anycast routing is not yet supported by the current DTN standard (Contact Graph Routing). The proposed approach yields improved performance for space applications that require as-fast-as-possible data returns.
