Required Information for Prototype
This page contains information which has to be provided by partners intending to contribute to the prototype.
Topological information
A partner might be willing to provide (layer 3) information about a part of his network. It would be desirable if this part could also comprise the link to Geant. In this case, some topological information is needed, i.e. information about network nodes (routers, switches), interfaces, and interface connections (see corresponding topology tables in the JRA1_D1.4_Database_Schema). For the prototype the information can be provided in a static way. This means to just send a list of nodes, interfaces, and connections. To allow for an easy generation of the CNM/Nemo maps, geographical locations of the network elements should be provided if possible.
Node information
| information | remark |
| name | DNS name |
| IP address | |
| geographical coordinates | allow for easy map creation |
Name has to be unique in network; node can be a router or a switch.
Interface information
| information | remark |
| name | if_decr MIB variable |
| IP address | needed for identification |
| node name | name of the corresponding node |
At this stage we are only considering physical interfaces, no virtual subinterfaces. Inferface names have to be unique in network.
Connection information
| information | remark |
| interface name1 | |
| interface name2 | |
| interface name3 ... | optional, allow for multipoint links |
Utilisation data
A possibility to retrieve current utilisation data from the collection RRD needs to be provided (e.g., by provisioning of an SSH account).
