A PCE-Based Architecture for Application-Based Network Operations

2015

Regarding the dominance of IP applications and the requirement of providing quality of service for users, it is critical to provide an scalable network architecture capable of supporting sufficient Quality of Service (QoS). Of the two network models (Integrated Services and Differentiated Services) approved by the Internet Engineering Task Force (IETF) [1, 2], the differentiated service model has gained wider acceptance because of its scalability. Differentiated Services (DiffServ) QoS architecture is scalable but inadequate to deal with network congestion and unable to provide fairness among its traffic aggregates. Recently, IETF has recommended additional functions including admission control and resource discovery to enhance the original DiffServ [2]. In this thesis, we propose a new framework based on DiffServ. The new architecture, called Fair Intelligent Congestion Control DiffServ (FICC-DiffServ), applies the FICC algorithm and control loop to provide fairness among traffic aggregates and control congestion inside DiffServ networks. The augmented architecture is realisable within the existing IP network infrastructures. Simulation results show that the FICC-DiffServ performs excellently in terms of guaranteed fairness, minimised packet delay and jitter, as well as being robust to traffic attributes, and being simple to implement. Moreover, providing end-to-end QoS for Internet applications presents difficult problems, because the Internet is composed of many independently administrative domains called Autonomous Systems. Enabling end-to-end QoS, negotiations between domains is then crucial. As a means of negotiations, interautonomous system QoS routings play an important role in advertising the available network resources between domains. In this thesis, the Border Gateway Protocol (BGP) is extended to provide end-to-end QoS. The BGP is selected for two reasons: (1) BGP is an inter-domain routing protocol widely used on the Internet and (2) the use of attributes attached to routes makes BGP be a powerful and scalable inter-domain routing protocol.

Future Internet

Future Internet is a general term that is used to refer to the study of new Internet architectures that emphasize the advancements that are paving the way for the next generation of internet. Today’s internet has become more complicated and arduous to manage due to its increased traffic. This traffic is a result of the transfer of 247 billion emails, the management of more than a billion websites and 735 active top-level domains, the viewing of at least one billion YouTube videos per day (which is the source of main traffic), and the uploading of more than 2.5 billion photos to Facebook every year. The internet was never anticipated to provide quality of service (QoS) support, but one can have a best effort service that provides support for video streams and downloaded media applications. Therefore, the future architecture of the internet becomes crucial. Furthermore, the internet as a service has witnessed many evolving conflicts among its stakeholders, leading to extensive researc...

Abstract: The next generation Internet needs to support multiple diverse application contexts. In this paper, we present Internet 3.0, a diversified, multi-tier architecture for the next generation Internet. Unlike the current Internet, Internet 3.0 defines a new set of primitives that allows diverse applications to compose and optimize their specific contexts over resources belonging to multiple ownerships. The key design philosophy is to enable diversity through explicit representation, negotiation and enforcement of policies at the granularity of network infrastructure, compute resources, data and users. The basis of the Internet 3.0 architecture is a generalized three-tier object model. The bottom tier consists of a high-speed network infrastructure. The second tier consists of compute resources or hosts. The third tier consists of data and users. The “tiered ” organization of the entities in the object model depicts the natural dependency relationship between these entities in ...

In recent years, business on the Internet has exponentially increased. Consequently, the deployment and management of business applications on the Internet is becoming more and more complex, which requires the development of new Internet architectures suitable to efficiently run these business applications. In this paper, we present and evaluate several computing models for application service providers and introduce the serverbased model and the corresponding Internet architecture. Two case studies, which use the proposed architecture for application deployment, are also described in the paper.

This position paper presents SoftINTERNET an initiative for a service-aware and management-aware network control infrastructure for heterogeneous networks (i.e., wired and wireless) that uses software driven features for the elaboration, development, and validation of networking concepts. The proposed infrastructure aims to optimally integrate the connectivity and management layers. It operates across multiple network environments and on top of private and public network clouds utilising fixed and mobile virtual resources, OpenFlow enabled network devices like switches and routers, and networks of Smart Objects. In this position paper, we discuss the motivation, architecture and research challenges for such a promising concept.

Today's Internet remains faithful to its original design that dates back more than two decades. In spite of tremendous diversity in users, as well as the sheer variety of applications that it supports, it still provides a single, basic, service offering-unicast packet delivery. While this legacy architecture seemed adequate till recently, it cannot support the requirements of newer services and applications which are demanded by the growing, and increasingly sophisticated, user population. The traditional way to solve this impasse has been by using overlay networks to address individual requirements. This does not address the fundamental, underlying problem, i.e., the ossification of the Internet architecture. In this paper, we describe the design of a new Service Oriented Internet framework that enables the flexible and effective deployment of new applications and services. The framework we describe utilizes the existing IP network and presents the abstraction of a service layer that enables communication between service end-points and can better support requirements such as availability, robustness, mobility, etc., that are demanded by the newly emerging applications and services.

From its inception, the Internet was not intended as the worldwide universal communication platform. It developed over almost four decades to its current state. As a result of this unplanned evolution, we currently witness scalability problems, increased complexity, missing modularity as well as missing flexibility for emerging services. In this report we focus on two selected issues: i) the changing routing paradigm and ii) edge-based intelligence. We will then present a variety of projects on future Internet and finally assess recently established experimental facilities and their role in the Future Internet design.

The paper presents a novel end-to-end seamless framework to support end-to-end Quality of Service and Traffic Engineering. The network model is based on the MPLS/DiffServ paradigm and addresses the definition of a network architecture according to both users and network providers requirements. A first solution relies on the centralized MPLS/DiffServ based Multi-protocol Access Inter-Domain (MAID) architecture. This architecture allows a seamless QoS-IP service setup through proper Users-Network Interfaces and inter-domain communication through Network-to-Network Interfaces. A fully distributed solution is also presented to address critical scalability issues and to improve network resilience. The overall architecture has been validated by means of functional tests carried out on operational testbeds based on Linux PC platforms.

This document describes the final cloud networking architecture proposed by SAIL work package D. Cloud networking aims at providing on-demand elastic network services to connect existing data centre based cloud infrastructures across wide area networks. In order to achieve that we propose the flash network slice, a network resource that can be provisioned and reconfigured in a timeframe that is compatible with current provisioning of virtual machines in a data centre. We consider a multi-provider scenario, where network and data centre providers must cooperate to implement global virtual infrastructures. This is enabled through provisioning interfaces and inter-provider protocols defined in the present architecture. The architecture introduces a layering of functions, interfaces and interactions within single cloud network operators, across cloud network operators, and with cloud network customers to implement complete end-to-end services. Management algorithms for user goal transla...

t the heart of the success and power of the worldwide IP Internet are the general-purpose protocols in the TCP/IP protocol suite. Although these protocols, such as TCP and IP, provide a flexible framework for building diverse applications, two limitations can be seen precisely because of their success and generality. First, they evolve more slowly than the changes in networking technology and application requirements. Second, they trade some loss in efficiency for their ability to handle increased heterogeneity.
