Abstract
It has been claimed that Distributed Restoration Algorithms (DRAs) have considerable advantages in terms of speed compared to centralised restoration schemes. However, these statements have always been based on simulations of the algorithms only. In order to study DRAs in a real environment, a testbed for experimenting with restoration in ATM networks has been realised. The testbed consists of five 8×8 STM1/ATM cross-connects, and is supervised by a central network management system. Hereby, provisions have been made to incorporate a maximum of flexibility, in order to test various restoration mechanisms, while striving for optimal performance.
The DRA has been integrated into the testbed environment and its robustness has been demonstrated for various network configurations of the testbed. Early results show that it is indeed possible to find the alternative routes within the call dropping time limit (± 2 seconds).
