Abstract

A forwarding node decapsulates and encapsulates data. The decapsulation may be performed using pattern matching techniques and the encapsulation may be performed using pattern insertion techniques. The decapsulation and encapsulation are preferably performed by hardware devices such as application specific integrated circuits (ASICs) to enhance the speed of such operations. The decapsulation and encapsulation may be independent of each other and performed on a per virtual circuit basis.
