PCI Express transactions can be transmitted via a shared PCI Express infrastructure. At an infrastructure ingress point an additional header comprising at least a source identifier and a target identifier is generated for a transaction packet that comprises a header portion, a data portion and an end-to-end CRC portion. The transaction packet is then transmitted with the additional header from the ingress point to an egress point. At the egress point the additional header is removed. The additional header can further include a resource key. It can further include protection information such as a CRC.
