Patent ID: 8799519

Claim:
A network-to-network bridge, coupled between a first system and a second system, comprising: a first network adapter, comprising a first bus interface and a first network processing stack, wherein the first bus interface receives a first data from the first system, and the first network processing stack encapsulates the first data as a first encapsulated data; and a second network adapter, comprising a second bus interface and a second network processing stack, wherein the second network processing stack takes the first encapsulated data as first decapsulated data, and sends the first decapsulated data to the second system via the second bus interface; wherein a transport layer of the first network processing stack is integrated with a transport layer of the second network processing stack, and an Internet layer of the first network processing stack is integrated with an Internet layer of the second network processing stack, wherein the first network processing stack and the second network processing stack do not comprise a network access layer.
