Monitoring CAP8 and SURAP networks (SRNTN-12)
Michael Cote · NASA STI/Recon Technical Report N · 1990
Abstract : Network monitoring is necessary for debugging protocols, measuring network performance, determining routes, and predicting network functionality. These tasks require data collection. Network Monitoring systems must poll Low- Cost Packet Radios (LPRs) for specific types of data, then process it for an operator. The Monitoring Data Packets (MDPs) specified in this document provide a flexible mechanism for monitoring systems to collect this data from an LPR network. Specific SURAP network monitoring applications that require MDPs are: Siting Aids for deploying the LPRs. NetMan for global network management, and the NIU (Network Interface Unit) for local network information. This document specifies the MDP formats for SURAP1 and SURAP2. These formats (see Appendix A) are the result of merging the packet radio PDP (Performance Data Packet) and the DIP (Device Information Packet). The remainder of the data is derived from the CAP LROP and from information which in the CAP8 networks, has been available only from the PR itself using the XRAY tool.
