ProNet: A policy network environment

Network and business management convergence is seen as the next step towards harmonizing information technology resource allocation with target business goals. This paper proposes a management platform that starts at the specification of business targets in the form of policies and goes all the way to enforcing them in a next generation Quality of Service aware network. We specified both a policy language and a parser and also implemented procedures for mapping policies into underlying network mechanisms. Furthermore, case studies presented in this paper show performance results of network services controlled by such policies.     

Security considerations in a network management environment

Considers the security aspects of communication between two management processes operating in different management domains; identifies two major risks: the security of information exchanged during the management association, and control of access to the management information base (MIB); and enumerates the various threats that must be guarded against and possible methods of attack. Security techniques, including symmetric and public key cryptosystems, are employed in the design of a method of achieving a secure management association. A scheme of authorization control for MIB access is developed. The management of an open system's network resources takes place in the context of a management association. The resources themselves are controlled by an agent process which presents a view of these resources to the outside world as a number of managed objects, each of which contains a number of attributes. The collection of objects presented to the outside world by the agent is known as the MIB. A manager process regulates the operation of the managed resources by engaging in a management association with the agent and instructing it to carry out simple operations on elements of the MIB. Within a single management domain where all processing nodes and network links are under the control of the same administration, security is not such a critical issue. However, when the management association takes place across the boundary between two separate management domains, and make use of public data networks, security issues must be considered in greater detail     

Integrated network management in an enterprise environment

Various aspects of integrated network management for business enterprises are discussed. Two categories of communications resources are considered: those that provide interfacility networking, such as circuit-switching or packet-switching telecommunications networks, and those that provide intrafacility networking, such as some form of local area network. The topics covered include: the network management environment within an enterprise; network management elements; the requirements for enterprise network management; a basic architecture for integrated network management; value-added services that expert system modules can provide; current approaches; and possible migration strategies for achieving integrated network management     

An integrated management environment for network resources andservices

Technological and human factors have contributed to increase the complexity of the network management problem. Heterogeneity and globalization of network resources, on one hand, have increased user expectations for flexible and easy-to-use environments; on the other hand, they have suggested entirely novel ways to face the management problem. Several research efforts recognize the need for integrated solutions to manage both network resources and services in open, global, and untrusted environments. In addition, these solutions should permit the coexistence of different management models and should interoperate with legacy systems. In the paper, we define a general architecture based on a distributed processing environment (DFE) that offers a large set of facilities to the application level. We have developed the MESIS management environment shaped after the above architecture and its DPE facilities with mobile agents technology. MESIS handles, in a uniform way, both resources and services, and focuses on two crucial properties: interoperability to overcome heterogeneity, and security to grant users safe and protected operations. The Agent Interoperability Facility supports compliance with CORBA-based management systems and with MASIF agent platforms. The Agent Security Facility provides authentication, integrity, privacy, authorization, and secure interoperation with CORBA systems     

Satellite network management in a crowded spectral environment

The domestic satellite industry has grown from the start-up phase to a position of relative maturity under a variety of flexible regulatory policies. This article focuses on two areas of policy which are critical to future growth in the industry. First, the existing policy governing orbital assignments is reviewed and recommendations presented for future policy changes. Second, the article stresses the need for policies to insure that all participants can operate in an environment free of undue frequency interference. The article concludes that the public interest motivation behind these policies is best served by a balance between regulatory oversight and industry self-help.

A secure active network environment architecture: realization inSwitchWare

An active network is a network infrastructure which is programmable on a per-user or even per-packet basis. Increasing the flexibility of such network infrastructures invites new security risks. Coping with these security risks represents the most fundamental contribution of active network research. The security concerns can be divided into those which affect the network as a whole and those which affect individual elements. It is clear that the element problems must be solved first, since the integrity of network-level solutions will be based on trust in the network elements. In this article we describe the architecture and implementation of a secure active network environment (SANE), which we believe provides a basis for implementing secure network-level solutions. We guarantee that a node begins operation in a trusted state with the AEGIS secure bootstrap architecture. We guarantee that the system remains in a trusted state by applying dynamic integrity checks in the network element's runtime system, using a novel naming system, and applying node-to-node authentication when needed. The construction of an extended LAN is discussed

A cognitive mobile sensor network for environment observation

Nowadays, with the development of industrialization and urbanization, air pollution has been a serious problem all of the word. Air pollutant is harmful to human and ecological environment, for example, SO₂ and NO₂ produced by industry are vital to living organisms, greenhouse air such as CO₂ causes global warming. As a result, environmental monitoring is of great importance for human beings.This paper proposes a scheme to implement environmental monitoring. In particular, wireless sensor network collect data from surrounding environment and mobile communication system receive and process these data. To avoid network congestion, a cognitive protocol is proposed for wireless sensors accessing to mobile network. Besides that, a dynamic working scheme is also proposed for sensors so that data collection rate can be adapted to the situation of network.     

A distributed industrial battery management network

This paper discusses a control network organization for industrial battery management. The battery network is logically partitioned into strings containing groups of cells. These groups of cells are managed locally by distributed control nodes that communicate through the local controller area network (CAN). Battery information is communicated to the remote user through TCP/IP. Both CAN and TCP/IP are connected through the gateway database, allowing for transitions from the battery process time and data volume domain into that of the remote user. The system architecture is based on multiple concurrent processes that facilitate necessary battery monitoring and charge management as well as availability of timely interaction with remote users. Autonomy of these processes is encouraged through the distributed data storage organization. Modeling and testing of the proposed architecture reflects the potential capacity for managing battery requirements and network traffic. Scalability of the approach to suit battery network size may also prove useful to serve other similar applications.

A platform for heterogeneous interconnection network management

A comprehensive network management function built into the interconnection network provides a means of meeting user needs of fault tolerance, performance, accounting, and security. However, meeting these needs on a heterogeneous interconnection network is several levels more complex than on a homogeneous network because of the existence of multiple protocol stacks for communication. An architecture that will solve this problem by analyzing the heterogeneous interconnection network as a single entity is proposed. The authors present the design issues evaluated in choosing this approach and establish the need for the various components in this architecture. An overview is presented of each of the components, and their place in the architecture is pointed out     

A synchronous digital hierarchy network management system

The critical issues in multivendor environments and operation systems of telecommunication networks essential to speeding up the handling of service orders and service restoration after failures are discussed. To overcome these problems as the software backlog grows, the authors propose the application of a telecommunications management network (TMN) architecture together with an object-oriented network resource (ONR) model. The second phase of the synchronous digital hierarchy (SDH) network management system, which is based on the TMN architecture and ONR model, is examined
