Abstract:
1. An article of manufacture comprising a computer readable storage device implemented at an initiator node including code executed to communicate with a target node and to perform operations, the operations comprising: communicating with the target node using a first protocol layer that interfaces with an interface layer to establish a connection with the target node; communicating, by the interface layer, login requests and responses between the target node and the first protocol layer to establish the connection for a second protocol layer; creating, by the interface layer, data structures to enable communication with the target node to establish the connection with the target node for the second protocol layer; invoking an extension layer for the second protocol layer upon receiving a last response to establish the connection from the target node; passing the data structures to the extension layer, wherein the extension layer uses the data structures to communicate with the target node using the second protocol layer; and issuing, by the extension layer, an invocation to terminate the interface layer in response to invoking the extension layer, wherein the extension layer uses the data structures created by the interface layer to communicate with the target node.
