- Feasibility of Flow-Based Optical Provisioning in GEANT
- Traditionally the difference between telephone and data networks has been quite sharply demarcated. Since a telephone call is characterized by a set up time that is negligible compared with the call duration, it makes sense to allocate it into an end-to-end circuit. On the other hand, data transmission has to...
