Contemporary network management frameworks have limited high-level functionalities. This makes administrator's manual intervention a common necessity, which is a highly complex activity for heterogeneous networks. State of the art research projects deal with methodologies to create high-level intelligent management systems that attenuates administrator's dependence. But making real implementations...
Networked resources are of increasing complexity and have to be configured properly to guarantee their operation. Within the IETF, current efforts are focused on both a protocol and a data model definition language for configuration management. The NETCONF protocol describes the communication between devices to be configured and configuration applications. NETCONF does not describe how configuration...
This paper proposes a new way to complete the interface model mapping from CORBA to ontology in the field of network management, which is interface model mapping adapter. The adapter consists of three parts, which are CORBA interface analyzer, mapping controller and ontology information database. The adapter can automatically map the CORBA interface model to ontology interface model. Therefore, we...
NETCONF protocol based on XML can well solve some problems in the SNMP. When managing the variety network equipment of complex network, the versatility and scalability of the management system of the simple NETCONF have become a major problem. This paper applies Web Services to NETCONF network management, using SOAP,WSDL,UDDI and other technology, we make some improvements to NETCONF network management...
While the current Internet is successful in many aspects, management of the current Internet has a set of associated systemic and business problems. This paper discusses those problems and presents a summary of management research efforts on the future Internet. We present the design requirements for future Internet management such as architecture, protocol, knowledge representation, and market aspects.
In this paper we present a distributed and automated network services monitoring and configuration framework composed by a monitoring sub-system and a service replication sub-system. We will focus on the details of the configuration sub-system, capable of static, dynamic and contextual parameterization and service replication, independent of software and hardware implementations.
Considering the problem of unified description of data modeling languages for computer network management, information specification ontology may be a prospective solution. However, basics of a unified mathematical theory are still lacking for ontology building. Delighted by the philosophical thinking of conceptual scheme for descriptive metaphysics, this paper tries to utilize formal concept analysis...
The third generation network which is vigorous nowadays will be followed by an all-IP infrastructure referred to as Next Generation Networks (NGN) in the near future. More specifically, the IP Multimedia Subsystem (IMS) is the only standardized way to offer IP based services that are enabled by one common core and all types of access networks and devices. The heterogeneity and mobility of the IMS...
Recently, traffic classification (TC) becomes more and more important for network management and measurement tasks. The new-coming machine learning based classification methods can achieve high classification accuracy and fast identification ability; however, all these related TC methods up to now always have the assumption of the stability of classification model constituted from network traffic...
In 2006, the IETF released its latest effort, NETCONF, a brand new network management protocol, which is based on the XML encoding method. The NETCONF protocol is thought to be able to meet the requirement of configuration management which SNMP fails to do well. The NETCONF protocol also performs better in other fields such as the efficiency, more flexible operations, etc. But, as a new protocol,...
As SNMP management system has some weaknesses due to its built-in functional limitation, NETCONF, with XML as its data encoding scheme, is viewed as a promising solution for future network configuration management. To make NETCONF interoperable and capable of manipulating data in a standardized fashion, an extensible data modeling language, YANG, was proposed to model data including configuration...
End-to-end broadband service delivery requires remote management of devices in the home network, beyond the home gateway (HG). The service provider can only put limited requirements to these of-the-shelf devices, and therefore has to make intelligent use of their given control and management protocols. We developed a demonstrator for the remote management of Universal Plug and Play (UPnP) devices...
The efficient configuration management of heterogeneous network devices from different vendors is a great challenge. The network configuration protocol (NETCONF) is presented as a new solution. It aims to overcome the shortcomings of simple network management protocol (SNMP) and command line interface (CLI) which are predominantly used for configuration tasks at present. This paper gives an architecture...
These days, the NETCONF protocol has evolved as an XML-based standardization to meet the ever-pressing configuration management demands. And with the emergence of NETCONF, it is expected that a separate effort to study data modeling in the interest of network management should be undertaken. XML schema and YANG have become two main candidate data modeling languages for NETCONF-based network management...
Communication services are surrounding our daily life; internet, mail, cellular phones... These services are managed by several protocols. In this paper we propose a generic model for the Ethernet protocol based on time Petri nets. A complete modular service-protocol model can help in better managing services and protocols and to easily change a system element without affecting the other elements...
One of the challenges in designing computer networks is "queue management and congestion avoidance". There are several studies for congestion reduction and controlling such as random early detection (RED) and its variants. More recent works on developing congestion avoidance methods include modeling a TCP flow in an active queue management (AQM) of a bottlenecked network link. Rather than...
