A comparison of the network managements cmip and snmp

SDN is a network approach that separates the control plane from the underlying systems that forward traffic to the selected destination. In SDN networks, management functions have to be effective to ensure performance and availability.

Existing studies, use cases and ONF SDN features are used as sources of information that help in identifying and evaluating management functions.

The categorization of the evaluated functions according to the FCAPS model, allows us to argue that, through the perspective of FCAPS model, the Network Management of OpenFlow based SDN networks can be considered effective as soon as it is supported with traditional network management mechanisms and third party OpenFlow-companion solutions.

Issues that still exist in limited number of management functions mainly concern carrier-grade networks. Further investigation, programmability effort and continuous development of OpenFlow is required. I would like to thank my supervisor, Professor Andreas Pitsillides for giving me the opportunity to work with an interesting and emerging technology.

His guidance and support played a very significant role to the development and completion of this thesis. I would also like to thank my family for being supportive and patient throughout the thesis work.

In SDN approach, the process of overseeing a network and taking corrective actions to ensure performance and availability, as has always been in traditional networks, continues to be challenging and of great importance.

In this study, the effectiveness of SDN management will be investigated in the context of the ISO network management model. The identified issues will be reported in order to contribute to future improvement of SDN management.

However, certain problems in network management remain unsolved while new challenges in network management are also expected to arise from the deployment of SDN. Network management of traditional networks is strongly affected by complexity and heterogeneity. Network operators and corporate network administrators quite often have to deal with low-level vendor-specific configuration activities in order to implement higher level network policies.

The closed and proprietary integration of network devices prevent the adoption of best possible solutions in network management as the network operators remain locked-in by vendors.

Network operators have to implement frequent changes to the state or the configuration of a network in order to enforce various high level, and sometimes urgent, policies aiming to respond to security threats, data traffic needs or performance issues.

Nowadays, network management is not yet able to provide sufficient mechanisms to address the wide range of network events that may occur [1]. Another issue in network management is the lack of network tools that would facilitate network operators to implement complex tasks and sophisticated policies.

Most of the 8 complex operations upon network devices, require from network operators the knowledge of vendor-specific low level configuration commands. The expertise of the network operators play an important role in implementing such configurations.

However, expertise is not enough when network operators have to perform frequent configuration changes that affect the operational state of the network. The risk of misconfiguration increases and operators chose to use ad hoc scripts or external tools. Today s networks consist of many interconnected, proprietary and vertically integrated devices.

Due to vertical integration, vendors strive to fulfill the demand of network operators for deployment of new network protocols and functions. Innovation in network management is then limited resulting in lack of techniques and tools that would allow network operators to analyze and troubleshoot low-level configurations.

Obviously, there is a need to improve the visibility and the tools that facilitate complex network policies.

A Comparative Study of TR-069 SNMP and CMIS/CMIP protocol

OpenFlow with its potential and limitations is expect to play a determinant role in the future of network management over SDN networks. Software Defined networking is a new approach in computer networks that simplifies network design and operation by decoupling network control and data planes [2], and and is expected to reduce the cost of managing networks by providing programmable network services [3].

In SDN, network devices switches, routers and firewalls are simple packet forwarders while the intelligent part of control logic is implemented in the controllers.

Some obvious benefits of this architecture are the centralization of network configuration and the ability to introduce new ideas in the network through software programs [1]. But what could happen if control plane is misconfigured while operating? Could this cause unexpected outages in network services?Jul 08,  · Hi Julio - and thanks and no we don't go back to the 80s..

I did a few years with ISO/ITU and IETF and the driver for standards was our engineering knowledge coupled to input fro. In this report I will cover advantages and disadvantages of both Common Management Information Protocol (CMIP) and Simple Network Management Protocol (SNMP)., as well as discuss a new protocol for the future.

I will also give some good reasons supporting why I believe that SNMP is a protocol that all network administrators should use.
