Resilience of Backbone Provider Networks

چکیده
The Internet has evolved to today's complex and heterogeneous critical infrastructure. Structurally, the Internet has hierarchy, composed of interconnected and tiered service provider networks. Furthermore, services are provided at different layers that makes the collective analysis of the Internet very difficult. The primary focus has been on the logical aspects of the topology, since tools have been developed to collect, measure, and analyse IPlayer properties of the Internet. On the other hand, physical topologies provide services for logical layers, and defining physical connectivity is a major research challenge. Multiscale modelling and simulation of the Internet, while considering the multiple layers, is promising. Moreover, to study the behaviour of the Internet under correlated geographic failure scenarios, physical topologies are necessary. Understanding the structure below can help design resilient upper layers.

Extensions to the Virtual Private LAN Service (VPLS) Provider Edge (PE) Model for Provider Backbone Bridging
The IEEE 802.1 Provider Backbone Bridges (PBBs) specification defines an architecture and bridge protocols for interconnection of multiple Provider Bridged Networks (PBNs). Provider backbone bridging was defined by IEEE as a connectionless technology based on multipoint VLAN tunnels. PBB can be used to attain better scalability than Provider Bridges (PBs) in terms of the number of customer Medi...

The scalability of Hierarchical Virtual Private LAN Service (H-VPLS) with Ethernet access networks (RFC 4762) can be improved by incorporating Provider Backbone Bridge functionality in the VPLS access. Provider Backbone Bridging has been standardized as IEEE 802.1ah-2008. It aims to improve the scalability of Media Access Control (MAC) addresses and service instances in Provider Ethernet networ...

Network-provider-independent overlays for resilience and quality of service
Overlay networks are viewed as one of the solutions addressing the inefficiency and slow evolution of the Internet and have been the subject of significant research. Most existing overlays providing resilience and/or Quality of Service (QoS) need cooperation among different network providers, but an inter-trust issue arises and cannot be easily solved. In this thesis, we mainly focus on network...
متن کاملResilience in Computer Network Management
The protection of network infrastructure and services is one of the main issues network managers face today. This paper investigates this matter through the study of network resilience. A resilience factor (RF) is proposed to take into account topological aspects of the network and also the amount of traffic losses under stress conditions. The proposed factor is evaluated using a real network b...
