Delay-Tolerant Networkingrdquo (DTN) is a neologism used for a new store-and-forward architecture and protocol suite intended for disrupted networks where there is intermittent or ad-hoc connectivity. This has been proposed as one approach to supporting delay-tolerant networks. Work in the late 1990s on the ldquoInterplanetary Internetrdquo forms the basis for current DTN protocols and architecture...
Recent years have witnessed a huge increase in the number and variety of Internet applications, as well as on the number and diversity of security attacks to network users and systems. Consequently, the need for an accurate mapping of traffic to its corresponding applications has also raised in order to allow ISPs to provide better Quality-of-Service (QoS) standards, implement traffic engineering...
In order to effectively manage network resources and to serve different traffic needs, several works have been done in the QoS area. Basically, ldquomulti-field (MF) packet classifiersrdquo classify a packet by looking for multiple fields of the IP/TCP headers, recognize which flow the packet belongs to, and according to this information, provide service differentiation in IP networks. However, for...
QoS qualifiers in the IP header are prone to attacks. Malicious modifications may lead to theft of service as well as denial of service. Standard IPsec does not cover these header fields, leaving them prone to attacks. The article proposes a variant of the IPsec authentication header that includes protection of these fields. The solution is designed for single-domain networks with planned origin,...
