Enhancement of a module for the vizualization of multilayer single-domain competititvity

Résumé du document

Distributed applications such as Grid Computing and Service Oriented Architecture (SOA), may benefit from the capability of monitoring (dynamically requesting and displaying the status of a network) for management purposes. This document presents the enhancement of a graphical tool named NetView which was implemented in Santa Anna Laboratories, and allowed applications to display and monitor a generic network topology expressed as an XML-based file. In particular NetView may be used for displaying a multitude of aspects regarding physical and Virtual networks topology. The advantage of the use of NetView is that the visualization process is accomplished by issuing a simple request in terms of parameters and without any reference to the network technology implementation details.

[...] By convention, area 0 represents the core or "backbone" region of an OSPF-enabled network, and other OSPF area numbers may be designated to serve other regions of an enterprise (large, business) network - however every additional OSPF area must have a direct or virtual connection to the backbone OSPF area. The backbone area has the identifier Inter-area routing goes via the backbone. OSPF is perhaps the most widely-used IGP in large enterprise networks. The OSPF Protocol can operate securely, optionally using a cleartext password or using MD5 to authenticate peers before forming adjacencies, and before accepting link-state advertisements (LSA).

[...] This work proposes the enhancement of a tool, named NetView, originally conceived for the graphical visualization of a generic network topology starting from input files expressed in the standard and XML-based GraphML format. Enhancements will go beyond the scope of the simple visualization of a generic network topology toward other types of visualizations enhancing the already established processes for visualization and adding other visualization processes cornering other aspects of the network such as the visualization of the established Label Switched Paths (LSP) or the visualization of the established connections among peers in a network.

[...] Hosts use RSVP to request a QoS level from the network on behalf of an application data stream. Routers use RSVP to deliver QoS requests to other routers along the path(s) of the data stream 4 -RSVP Session Start up: To initiate an RSVP session, the receiver first joins the sender or group (unicast or multicast) specified by an IP address. After the receiver joins a group, a potential sender starts sending RSVP path messages to the IP destination address. [...]
