Network resource
Under network resources is meant primarily logical as well as physical entities, which together form a usable end-to-end - network connection account for how the available bandwidth , maximum delay or latency , packet loss , maximum jitter , CPU time or storage space . The task of network resource management is to make these resources available with controlled and guaranteed data traffic parameters (see Quality of Service ).
“Network resources” is often used synonymously with bandwidth, sometimes contrasted with it, which indicates the relatively poor definition of the term. A good part of the delimitation difficulties arise from the fact that devices and components such as routers , switches , caches etc. have to be used to secure the logical resources (connection quality) . Under certain circumstances, however, these are only compiled and made available dynamically on request - a situation that occurs especially in grid computing . The discussion is therefore mostly limited to the logical specifications that must then be implemented at runtime using a broker solution or something similar.
