“…As part of their research, also the performance differences between XML and SNMP based management have been investigated [12], [13]. To determine bandwidth, they've measured the XML traffic at one side of the gateway, as well as the corresponding SNMP traffic at the other side.…”

Abstract-This paper compares the performance of Web services based network monitoring to traditional, SNMP based, monitoring. The study focuses on the ifTable, and investigates performance as function of the number of retrieved objects. The following aspects are examined: bandwidth usage, CPU time, memory consumption and round trip delay. For our study several prototypes of Web services based agents were implemented; these prototypes can retrieve single ifTable elements, ifTable rows, ifTable columns or the entire ifTable. This paper presents a generic formula to calculate SNMP's bandwidth requirements; the bandwidth consumption of our prototypes was compared to that formula. The CPU time, memory consumption and round trip delay of our prototypes was compared to Net-SNMP, as well as several other SNMP agents. Our measurements show that SNMP is more efficient in cases where only a single object is retrieved; for larger number of objects Web services may be more efficient. Our study also shows that, if performance is the issue, the choice between BER (SNMP) or XML (Web services) encoding is generally not the determining factor; other choices can have stronger impact on performance.

“…shows one of the manager and agent combinations in XML-based network management [2]. It shows the approach that requires a translation from XML to SNMP through a gateway [1] [2]. Since most network devices have legacy SNMP agents installed in them, this combination is simpler to implement in the current network environment, and is more appropriate for the current network management framework.…”

Abstract. SNMP-based network management is simple but lacks scalability and efficiency of processing the management data as the number of agents increases. XML-based network management is a new paradigm developed to overcome these limitations. One of the main challenges is how to distribute the management tasks to achieve efficiency and scalability. In this paper, we propose a framework using JPVM to distribute the management tasks among multiple gateways. We compare the performance of three approaches, namely the static weighted load balancing approach, the equal work non-weighted load balancing approach, and the single gateway approach. The first approach provides better communication time between the XML-based manager and the SNMP agents. It takes advantage of the XML, DOM, and Java servlets.

On the Performance and Scalability of Web Services for Monitoring MPLS-based Networks

Web Services is an XML-based technology that has attracted significant attention for building distributed Internet services. Considerable research efforts have been trying to extend it to become a unifying management technology; initial evaluation efforts have demonstrated promising application potential in the domain of network and service management. This paper analyzes the monitoring requirements of a management system used in architectures for providing quality of service, and shows how Web Services can be used effectively to fulfill these requirements. In order to achieve this, a WS-based framework was designed and a query tool was developed to support distributed, optimized retrieval of management information exposed as Web Services. The query tool supports selective and bulk retrieval from MPLS-capable routers. Management information retrieval is demonstrated through three monitoring scenarios, and the measured performance in terms of latency and bandwidth is compared against a conventional approach based on SNMP.
