Managing resilience in carrier grade networks: Survey, open issues and trends
IP/MPLS and Optical technologies are the foundations of current Carrier-Grade Networks (CGNs), due to both the flexibility of IP/MPLS to provide services with distinct requirements and the high transport capacity offered by new Optical technologies, such as Elastic Optical Networks (EONs). However, despite of the widespread adoption of these two technologies, interoperability issues still impac...
متن کاملMultilayer Quality and Grade of Service Support for High Speed GMPLS IP/DWDM Networks
IP over optical networks controlled by the GMPLS control plane have become the common infrastructure for a variety of services, such as triple play and grid applications. The traffic aggregation requires the services to be differentiated in a multilayer fashion, so as to guarantee higher levels of GoS and QoS to ‘gold’ traffic. This means that the traditional DiffServ technology needs to be com...
متن کاملA Novel Fuzzy Logic Base Scheduling Mechanism for Service Differentiation in IP Networks
Quality of Service (QoS) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. The differentiated services architecture (DiffServ) allows providing quality of service to users. The major DiffServ premise is that individual flows with sim...
متن کاملFault Tolerance and Resilience Issues in IP-Based Networks
A huge effort is currently put into the research of Quality of Service issues in the internet. Until recently, only little interest was given to the question of the resilience of IP based networks. However, with the growing commercial importance of the internet and the development of new real-time, connectionoriented services like streaming technologies or IP-telephony the resilience is becomin...
متن کاملEngineering End-to-End IP Resilience Using Resilience-Differentiated QoS
Network resilience is becoming a key issue in the design of IP-based multimedia and multiservice networks. The current discussion about IP network resilience centers around MPLSbased recovery mechanisms. Any well designed recovery strategy has to take into account the different resilience requirements of the single traffic flows in order to avoid excessive usage of bandwidth for standby links. ...
