Pending Interest Table (PIT) in Named Data Networking (NDN) architecture is complex in the forwarding operation in both upload of Interest packets and download of Data packets. PIT is considered useful for so many reasons in the centric-networking. These among other operations include: reducing bandwidth usage, communicating with no prior knowledge of publishers and subscribers, loop and packet loss...
Nowadays CLARA (Latin Americas Consortium for Advanced Networks) is partially stagnated with no grow since last update in 2013, with this review we hope in a near future offer a new proposal for updating and reactivation of advanced networks in Latin America. A step by step simulation was developed in order to get first approach to how CLARA works; then a step by step emulation was developed with...
The decoupling of control and data plane in software-defined networking (SDN) has been shown to be promising to improve routing performance in the context of intradomain routing. The applicability of SDN in inter-domain routing, especially with respect to route convergence, has not been properly explored. In this work, we propose a mathematical model to quantify the BGP convergence time for inter-domain...
As the Inter-domain routing security problem becomes increasingly prominent, the detection of AS (Autonomous System)-level Internet evolution has become a research hotspot. This paper introduces AS Reach ability Distance (ASRD) and AS Connectivity Distance (ASCD) based on temporal distance, used to characterize the difference of AS reach ability and connectivity at different time respectively, and...
Content Centric Networking (CCN) is one of the most promising network architectures of future Internet. In CCN, Content Router (CR) floods request in the network to find the content. This flooding may degrade the network performance by generating too much traffic. Also, in legacy CCN architecture, each CR caches all contents that pass through it. Thus, same contents are replicated in all CRs along...
In order to guarantee and optimize end-to-end Quality-of-Service (QoS) in heterogeneous and converged mobile Internet, a novel QoS routing algorithm proposed to optimize multiple QoS metrics on virtual Overlay platform based on Multi-Objective optimization is introduced at this paper. Because of the imprecise network information, the membership function and probability are combined to find a solution...
Information Centric Networking (ICN) has been proposed as an alternative design for the Internet with a focus on content centric communication rather than host-to-host communication such as telnet or ftp. This requires the data to be cached or stored at intermediate routers to satisfy the future demands for the same contents locally. The existing caching policies are either suboptimal or not suitable...
Vehicular Ad Hoc Network (VANET) is considered as a special application of Mobile Ad Hoc Networks (MANETs) in road traffic, which can autonomously organize networks without infrastructure. VANETs enable vehicles on the road to communicate with each other and with road infrastructure using wireless capabilities. In the last few years, extensive research has been performed to extend Internet connectivity...
It is very difficult to predict long-term network traffic behavior in a large-scale network such as Internet. Due to the competition among ISPs and Internet exchanges (IXs), Internet users always experience different kinds of QoS, that effectively affect the network traffic. Accordingly, this paper designs a traffic model in the IX environment based on 1-step Markov Chain. The model simulates the...
Content transfer, e.g. video transfer, is now becoming major traffic in the current Internet. Content transfer originally has a content oriented feature of “wherever content is retrieved, users only take care of what content they obtain”. Conventional traffic engineering aims to obtain optimal routes for traffic between ingress and egress router pairs, which has “location oriented feature, i.e. where...
Most Internet routing protocols have one of two algorithms lurking at their core — either Dijkstra's algorithm in the case of link-state protocols or a distributed Bellman-Ford algorithm in the case of distance-vector or path-vector protocols. When computing simple shortest paths these protocols can be modified to utilize all best paths with a combination of next-hop sets and Equal Cost Multi-Path...
Content-Centric Network (CCN) provides a cleanslate design for the Internet, where content becomes the primitive of communications. In CCN, routers are equipped with content stores, which act as caches for frequently requested content. This design enables the Internet to provide content distribution services without any application-layer support. On the other hand, as caches are integrated into routers,...
Despite the success story of Internet, the ossification in the underlying infrastructure has become a key problem for its development. Network virtualization allows de-ossifying the internet and it is already a hot research topic nowadays. Virtualization is a very successful technique for sharing and reusing of resources, resulting in higher efficiency. On the other side, there is a need to cope with...
Information-Centric Networking is (ICN) gaining increasingly concerns, as an important direction of the future Internet architecture research. To study the impacts of various cache policies on overall performance of ICN network, we formulate the in- network caching problem of ICN into Mixed-Integer Linear Programming problem. Furthermore, we infer that frequency-based cache policies like LFU are supposed...
The most important tendency of future Internet architectures is maintaining the best Quality of Experience (QoE), which represents the subjective perception of end-users using network services with network functions such as admission control, resource management, routing, traffic control, etc. Among of them, we focus on routing mechanism driven by QoE end-users. Nowadays, most existing routing protocols...
The worm is still one of the most serious threat to the Network security. The logical worm propagation model could characterize the propagation of Internet worms more exactly, and could be more helpful to carry out the worm protection, detection and suppression technology research. In the initial phase of this paper, a heterogeneous network oriented worm propagation model namely Enhanced-AAWP was...
Evaluating the reliability of Internet routing is important for an ISP to assess existing peer relationships or establish new peer relationships. Existing algorithms for network reliability computations take all routing paths as inputs. However, these paths may not be actually available for routing because of the constraints of routing policies in the Internet. In this paper, we propose an algebraic...
Internet core routers are facing challenges brought by the ever-increasing transit bandwidth and routing scale. In order to meet the requirements of highly efficient packet forwarding, some solutions propose to load a small portion of the BGP RIB entries into the FIB. Therefore the most popular prefixes, which contribute major traffic loads, need to be cached in the FIB as long as possible. In this...
Over the last years, the research community has been deeply concerned about the scalability issues that the Internet routing is facing. In this paper we study the economic incentives for the Global Routing Table (GRT) explosive growth by considering a commons model in which the GRT is a public resource. In particular, we analyze the motivations the ASes have for deaggregating their assigned address...
6LoWPAN is a new protocol that enables IPv6 to be used in wireless sensor networks. However, the hierarchical routing over 6LoWPAN (HiLOW) proposed by the IETF 6LoWPAN Working Group may be too simplified due to the use of dynamically assigned 16-bit short addresses in 6LoWPAN to establish a hierarchical tree between parent and children nodes for packet transmission since performance would degrade...
