Abstract:
1. A network interface within a network node, the network interface comprising: a functionally encapsulated unit of hardware containing all hardware components of which are necessary to maintain functionality of the network interface, having a microcontroller for addressing software within a storage medium executable by said hardware, and containing a protected address space; wherein the functionally encapsulated unit encapsulates a physical layer of the network node and extends up to a parent layer of the network node, wherein the physical layer provides network services of an OSI layer wherein, during operation, the functionally encapsulated unit maintains the functionality of the network interface even when hardware components external to the functionally encapsulated unit, but within the network node, are inoperable by encapsulating the physical layer up to the parent layer; and wherein said functionally encapsulated unit is accessible:
