  • Techniques for encapsulating point to point (PPP) over Ethernet frames
    Patent number: 8204080
    Abstract: Techniques for negotiating Point-to-Point Protocol (PPP) sessions over an Ethernet network include receiving configuration data that indicates a first node is connected to a second node thorough an Ethernet network that supports Ethernet frame payload sizes larger than 1500 octets. Request data is received at the first node from the second node. The request data indicates a request for PPP communications between the first node and the second node using a requested PPP payload size greater than 1492 octets. A particular PPP payload size greater than 1492 octets is determined. Response data is sent from the first node to the second node. The response data indicates that the particular PPP payload size greater than 1492 octets is to be used for PPP communications between the first node and the second node. These techniques allow better utilization of Ethernet Jumbo, Giant and Baby Giant frames.
