Due to the significant growth of link speeds, amount of data that should be stored on router line cards are rapidly increasing. Therefore, a large number of memory modules are required for packet storage. In addition, a high performance interconnection network on line cards is strongly needed for inter-communication between processing elements and memory modules. In this paper we propose a new interconnection...
In the paper the mathematical model of traffic management in the MPLS-TE DiffServ network is proposed. This model describes the processes of routing and distribution channel resource. In article the method of two-level traffic management in the MPLS-TE DiffServ network is offered to improve the scalability of the solutions on the basis of interactions prediction.
We investigate link-state advertising in multi-domain networks with dynamic traffic. A novel triggering scheme is proposed to monitor a subset of domain links, and thereby achieve a balance between salability and accuracy.
Presented in this paper is a dual routing engine-enabled optical network platform with multi-domains and multi-layers. Structure and key technologies of the platform are outlined. Experiments on it with 2 routing strategies are conducted, the results are discussed and the network scalability is evaluated.
We present a new Internet architecture based on de-conflated identities (ADI) that explicitly establishes the separation of ownership of hosts from the underlying infrastructure connectivity. A direct impact of this de-conflated Internet architecture is the ability to express organizational policies separately and thus more naturally, from the underlying infrastructure routing policies. Host or organizational...
We present an efficient key distribution scheme for sensor networks in which resource constraints and the possibility of node capture and malfunctions are considered. We deal with the problem of efficient routing and key distribution simultaneously. The resulting scheme is scalable and resilient to node captures and malfunctions. Under certain assumptions, the scheme has an upper bound of log2N on...
Many applications in the current Internet follow the multicast paradigm, not the unicast one that has traditionally ruled the design of TCP/IP. These applications are, therefore, required to construct overlay networks for multicasting, which unfortunately offers too little efficiency to support the immanent emergence of trillions of groups. IP multicast, which is the natural implementation of the...
Different routing schemes for multi-layer and multidomain optical networks are analyzed, and a novel routing architecture is described in the paper. Cooperation models between dual routing engine in large-scale multi-layer and multidomain optical networks are researched, and an optimal model is proposed and simulated. Then the scalability of dual routing engine architecture is validated on DRE testbed.
The separation between edge and core addresses has been proposed to address the scalability problem of the Internet routing system. One main challenge is to design an efficient mapping mechanism for the two address spaces. The layer structure is attractive because of its scalability and simple index mechanism, while existing layered mapping system lacks a clear structure study and faces serious deployment...
An IP fast reroute control architecture using a centralized control plane where the control plane and data plane are physically separated is presented. In IP fast reroute processes, route computation and failure restoration are independently performed. Our architecture places the route computation function in the central control server to ensure scalability. As for route configuration, the size of...
With the recent focus on cloud computing a new type of system topology came up: clusters in geographically distributed datacenters that are connected by high-latency networks. Current structured overlay networks (SONs) are not well prepared for such environments with heterogeneous network performance and correlated node failures. We show how the beneficial features of SONs, namely self-management,...
Research and discussion on the Internets addressing and routing scalability problems has been for more than a decade. IP aware growing population, and learned needs in terms of site multi-homing, traffic engineering, non-aggregatable address allocations and policy based routing have resulted in the continuous alarming growth of the routing tables in the Default Free Zone (DFZ). Constraints posed by...
So far, large computing clusters consisting of several thousand machines have been constructed by connecting nodes together using interconnect technologies as e.g. Ethernet, Infiniband or Myrinet. We propose an entirely new architecture called Tightly Coupled Cluster (TCCluster) that instead uses the native host interface of the processors as a direct network interconnect. This approach offers higher...
The increasing growth of the global Internet making the shortcomings of its unstructured topology and distributed routing algorithm are exposed more rapidly. To design a controllable, scalable and manageable backbone network with a simple, efficient architecture is very imperative. Among many topologies, Tree topology which has a natural hierarchical structure and explicit end-to-end transmission...
Controller Area Network (CAN) provides an inexpensive and robust network technology in many application domains. However, the use of CAN is constrained by limitations with respect to fault isolation, bandwidth, wire length, namespaces and diagnosis. This paper presents a solution to overcome these limitations by replacing the CAN bus with a star topology. We introduce a CAN router that detects and...
In large multi-domain networks, topology aggregation - besides assuring scalability - has a side-effect as it introduces undesired inaccuracies in the routing information. Such inaccuracy affects the efficiency of routing. In this paper, with the application of a threshold-based aggregation model, the relation between scalability and routing efficiency has been examined by evaluating two different...
This paper presents and compares different TE information dissemination strategies between Path Computation Elements (PCEs) in multi-domain optical networks. In such network context, recent studies have found that path computation only with local domain visibility yields poor network performance. Accordingly, certain visibility between domains seems necessary. Aiming to fit the confidentiality requirements...
In this paper, we take a fresh look at stub-site multihoming within the paradigms of an identifier/locator split architecture. More specifically, we investigate the possibility of enabling multi-homed stub network sites to improve the performance of their end-to-end TCP flows by leveraging the path diversity of the underlying network. We design a host-network co-operative mechanism for end-to-end...
In order to realize hierarchical routings that should be executed in large-scaled mobile ad hoc networks that vary their topologies considerably with time, we have developed autonomous clustering with high scalability and adaptability. In autonomous clustering, an entire network is divided into disjoint subnetworks (called clusters), and they are maintained by periodically sending messages within...
With the boom of network technologies, the Internet architecture is being challenged by new problems such as routing scalability and mobility in these days. Although some related proposals were proposed, an interesting and open issue is that how to support mobility in the locator/ID separation based routing scalability networks. In this paper, we propose MobileID, which is an efficient approach to...
