Multipath FEC scheme for the ATM adaptation layer AAL5

摘要

One approach to acilitate statistical multiplexing of bursty sources in ATM networks is dispersion of hte traffic over idenpendent paths.It has been shown within the literature that by disperison of traffic over disjoint paths it is possible to increase the Quality of service (QoS) (see e.g.,(Maxemchuck,1993),(Lee,1993)).In multipath schemes without additional error control,the resulting QoS depends on the worst-case path.By using a multipath scheme with FEC (Forward Error correction),it is posible to compensate cell losses.using error correcting codes like Reed-Solomon-Erasure Codes (RSE Codes,(McAuley,1990)),these schemes add redundancy and disperse the traffic using serveral transmision paths (Ding,1995).
