MEC or Multi-Access Edge Computing is a network service delivery architecture that enables cloud computing capabilities at the edge of the access network. Realisation of the MEC vision is challenging with current network technologies: service discovery and routing, secure network slicing and distributed mobility management require complex capabilities in the network. This demo features an OMEC use...
The COMPA (Control, Orchestration, Management, Policy, and Analytics) adaptive control loop realizes an automation pattern that can operate recursively at many layers in a carrier network. An overall COMPA autonomic control loop can orchestrate functions, themselves implemented as COMPA autonomic loops. Thus the COMPA automation patter can recurse right down to resource level in a network. One of...
The formal structure of information models and the controlled manner of accessing and changing such models brings both flexibility and control when managing network elements. However, keeping information models synchronized and consistent across network elements and management systems is a challenging task. Today this problem is exasperated with the advent of ephemeral network functions and elements...
The era of petabyte data has arrived as the digital big data universe continues its expansion toward exascale with massive volumes of data generated by diverse distributed sources. The size of big data makes it very difficult to gain insight into the meaning of data. In industrial applications, in order to explore both the meaning of data and the complex relationship between data components, big data...
Telecommunication companies with expensive networks may become the biggest beneficiaries of SDN; however, in contrast to traditional routers, the development of SDN controllers is driven by open-source projects with involvement of the industry. Two prevalent projects in SDN development are the OpenDaylight and the ONOS controllers. These SDN controllers are advanced in their development — having gone...
The advent of “Soft Networking”, where networks are composed of virtual nodes and links, promises to dramatically ease the definition and deployment of networks whilst allowing network applications that are limited only by the imagination of the developers of those applications. In such a dynamic environment, the Autonomic Management pattern supervised by policies has been recognised as holding more...
New technologies are changing the world of communication networks and even more so their management. Cloud computing and predictive analytics have removed the need for specialized compute hardware and created products that continuously search for and find insights in management data. Virtualization of networks and network functions, SDN and NFV, are beginning to be mature enough for production networks...
With the technological evolution in telecommunication networks, performance requirements such as better coverage, higher bandwidth, and lower latency have been pushed to new horizons. However, as a direct result network complexity has increased dramatically over the recent years, and with this complexity manageability has suffered. This paper presents the architecture of the E-Stream project which...
Currently the volume of telecom network management data is expanding exponentially, mainly due to the explosive growth in the number of communicating devices along with the increase in heterogeneity of the networks. Such scale of data obsoletes the traditional approach of extracting offline analytics from the network traces governed by some pre-defined schemes. In order to increase the efficiency...
The idea of virtualizing network functions is driven by recent advances in network-focused hardware. In 2012, several large telecommunication operators issued a call to action for Network Function Virtualization (NFV)1. The underlying idea is that every network service currently delivered on proprietary, application specific hardware should be deliverable using virtual machines. This means that routers,...
Monitoring and management of modern telecommunication networks has become more and more challenging due to the explosion in scale of data generated by network elements. Not only has the size of the network, the number of nodes, and the number of customers increased, but the amount and dimensionality of the data coming from each managed element has also increased. To support sophisticated monitoring...
The rapid growth in mobile and heterogeneous network has led to a massive increase in data traffic adding to the already significant challenges in network performance. Operators already face the problem that thousands of network incidents (e.g. dropped calls or packet delivery failures) remain unresolved due to the technological limitations. It is recognized that the use of network emulation/simulation...
The rapid development of network technology and its evolution towards heterogeneous networks has increased the demand for more efficient network monitoring and management capabilities in providing high quality communication services. Current research aims to support automatic monitoring and management of heterogeneous wireless communication networks. In this work sequential pattern mining is used...
The explosion in consumer devices has resulted in a significant increase in the number of mobile telecommunications nodes. As a result of increased device and node numbers, network operators have experienced a large increase in associated events. In such an environment, scalability and performance of event handling become important aspects for Operation Support Systems (OSS). A traditional approach...
Research and products in telecoms network management have long been focused on the automation of processes to keep complex managed networks in an operational state, while being profitable to operate for the network operator. Due to the ever increasing scale and complexity of the problem domain, coupled with specific constraints (legal, regulatory, technological change), a fully automated management...
Modern distributed applications and communication services have become increasingly complex, composed of diverse heterogeneous sub-systems, and it is progressively more unrealistic that the users of these systems will be able to manage them in a holistic end-to-end manner. In particular, it is increasingly difficult to understand how such systems operate, the meaning of errors, and how they can be...
Translating between network management policies is desirable if a system needs to map downwards from a high-level objective to low-level configurations or to feed information back upwards from a network event to a matching policy. Techniques for policy translation require elements of semantic mapping between levels of management policy within a continuum. The policy translation is difficult due to...
At last year's ICUFN we presented an architecture for managing ubiquitous computing networks and applications [1]. This year we want to show how we can implement this architecture to realise and deploy a small yet powerful management system. The use case for demonstrating our implementation is one of the most commonly used ubiquitous service - instant messaging. The described management system is...
Ubiquitous communication depends on distributed machine intelligence that relates the needs of the tasks to be performed to the available system services and resources. A critical part of this process is the understanding of contextually-sensitive data that can influence the offering and delivery of these resources and services. This paper describes a new extension of the FOCALE autonomic architecture...
Enabling interdomain and end-to-end management are major challenges for IT architectures supporting agile next-generation communications service providers. This requires explicit management of the interdomain relationships themselves rather than treating extradomain resources or services as equivalent to internal capabilities. In this article we describe a general layered model for describing interdomain...
