초록 ▼

An electronic device employing an efficient network protocol stack. The protocol stack comprises a network-level protocol layer configured to provide a transmission service for transferring data to and from a computer network, and a device-level protocol layer configured to send and receive information specific to an interface of the electronic device over the network via the transmission service of the network-level protocol layer. Alternately, each of the network-level protocol layer and the device-level protocol layer may be employed individually with other network protocol layers to construct a functioning network protocol stack.

대표청구항 ▼

We claim: 1. An electronic device configured to communicate on a computer network, the device comprising: a network adapter, the network adapter having a physical network interface configured to transmit packets to and receive packets from the computer network; wherein the device is configured to communicate according to a network protocol stack having: a network-level protocol layer configured to provide a transmission service for transferring packets to and from the computer network, and a device-level protocol layer configured to send and receive information specific to an interface of a remote electronic device over the network via the transmission service of the network-level protocol layer; wherein the network-level protocol layer is configured to interface a network layer with a transport layer of the International Standards Organization Open System Interconnection (ISO OSI) network protocol model; and wherein the network protocol stack further comprises: an Ethernet-type header; a network-level header operably attached to the Ethernet-type header; and a data frame operably attached to the network-level header. 2. The electronic device of claim 1, wherein the transmission service of the network-level protocol layer comprises a stream service. 3. The electronic device of claim 1, wherein the transmission service of the network-level protocol layer comprises a datagram service. 4. The electronic device of claim 1, wherein the device-level protocol layer is configured to communicate an Integrated Drive Electronics (IDE) command. 5. An electronic device configured to communicate on a network, the device comprising: a network adapter, the network adapter having a physical network interface configured to transmit packets to and receive packets from the network, wherein the device is configured to communicate according to a network protocol stack having a network-level protocol layer and a device-level protocol layer, wherein the device-level protocol layer is configured to send and receive information specific to an interface of a remote electronic device over the network via a transmission service of the network-level protocol layer, and the network-level protocol layer is configured to interface network layer packets with a transport layer of the International Standards Organization Open System Interconnection (ISO OSI) network protocol model; and wherein the network protocol stack further comprises: an Ethernet-type header; a network-level header operably attached to the Ethernet-type header; and a data frame operably attached to the network-level header. 6.

An electronic device configured to communicate with a second electronic device, wherein the electronic device comprises: a network adapter, the network adapter having a physical network interface configured to transmit data packets to and receive data packets from a network, wherein the electronic device is configured to communicate according to a protocol stack having: a network protocol layer defining a network protocol layer packet and operative to transmit a network-level command between at least the electronic device and the second electronic device, a device protocol layer defining a device protocol layer packet and operative to transmit a device command relating to a device associated with at least one of the electronic device and the second electronic device; wherein the network protocol layer packet and device protocol layer packet are transmitted within a single data packet; and wherein the protocol stack further comprises: an Ethernet-type header; a network-level header operably attached to the Ethernet-type header; and a data frame operably attached to the network-level header. 15. The electronic device of claim 14, wherein the device protocol layer packet is transmitted within a data frame of the network protocol layer packet. 16. The electronic device of claim 14, wherein the device protocol layer packet is generated within a data frame of the network protocol layer packet. 17. The electronic device of claim 16, wherein: the Ethernet-type header comprises no more than 14 bytes; and the network-level header comprises no more than 16 bytes. 18. The electronic device of claim 17, wherein the device protocol layer packet comprises: a first header segment; and a second header segment operably attached to the first header segment. 19. The electronic device of claim 18, wherein the device protocol layer packet further comprises at least one of: a header digest operably attached to the second header segment; a data segment operably attached to the second header segment; and a data digest operably attached to the second header segment.
