A switching node for an ATM network can selectably implement one of a plurality of call transforming procedures. The switching node stores characteristics of each connected communications link in a virtual connection and determines, for any ATM message the quality of service requirements for a particular transfer over a virtual connection. The selection of a call transferring process is based upon minimizing a particular potential error. Decisions concerning the implementation of correction procedures and the capability of the virtual connection to accommodate these requirements are made on a link-by-link basis. |
