Bandwidth allocation for permanent virtual connections.

摘要

This system (ATMS) comprises a plurality of interconnected nodes (NN1/NN4) to which server units (CLSD1/CLS3) and users (CLTE1/CLTE5, MAN1/2) are connected. Permanent virtual connections established between the server units constitute a virtual overlay network over which the users can communicate with each other in a connectionless way. The bandwidth reserved for communications on the permanent virtual connection is adapted dynamically according to the result of a comparison between the reserved bandwidth, as stored by counter means (CO1/CO4), and the used bandwidth, as measured by measurement modules (MC1/MC3).
