32 results about "EtherType" patented technology

EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame. The same field is also used to indicate the size of some Ethernet frames. EtherType was first defined by the Ethernet II framing standard, and later adapted for the IEEE 802.3 standard. This field is used by the data link layer to determine which protocol to hand over the payload to on the receiving end.

METHOD AND SYSTEM FOR SECURING A NETWORK UTILIZING IPSEC and MACSEC PROTOCOLS

Aspects of a method and system for securing a network utilizing IPsec and MACsec protocols are provided. In one or more network nodes, aspects of the invention may enable conversion between Ethernet packets comprising payloads secured utilizing IPsec protocols and Ethernet packets secured utilizing MACsec protocols. For example, IPsec connections may be terminated at an ingress network node and IPsec connections may be regenerated at an egress network node. Packets secured utilizing MACsec protocols may be detected based on an Ethertype. Packets comprising payloads secured utilizing IPsec protocols may be detected based on a protocol field or a next header field. The conversion may be based on a data structure stored by and / or accessible to the network nodes. Aspects of the invention may enable securing data utilizing MACsec protocols when tunneling IPsec secured data through non-IPsec enabled nodes.

Ethernet OAM at intermediate nodes in a PBT network

OAM may be implemented at an intermediate node on a PBT trunk in an Ethernet network by causing OAM frames to be addressed to the PBT trunk endpoint but causing the OAM frames to carry an indicia (Ether-type, OpCode, TLV value or combination of these and other fields) that the OAM frames are intended to be used for intermediate node OAM functions. The Ether-type, OpCode, and TLV values may be standardized values, or vendor specific values such as OpCode=51 or TLV=31 may be used. Addressing the OAM frames to the PBT trunk end point enables the OAM frames to follow the PBT trunk through the network. The OAM indicia signals to the intermediate nodes that the OAM frames are intended to be used to perform an intermediate node OAM function. The OAM frames may contain reverse trunk information to prevent the intermediate nodes from being required to store correlation between forward and reverse PBT trunks.

Method and system for tunneling macsec packets through non-macsec nodes

Aspects of a method and system for tunneling MACSec packets through non-MACSec-enabled nodes are provided. In this regard, aspects of the invention may be utilized for transmitting MACSec Ethernet packets over MACSec and / or non-MACSec-enabled network nodes. In one embodiment of the invention, additional header information may be inserted into a MACSec packet before transmitting the MACSec packet to a non-MACSec-enabled node. Accordingly, aspects of the invention may remove the additional header information from a packet received from a non-MACSec-enabled node to distinguish the packets comprising inserted additional header information, which may comprise a distinguishing Ethertype.

SDN-based network topology discovery method

The invention relates to an SDN-based network topology discovery method. The method comprises the following steps: sending a port state request to all connected SDN switches through a controller to obtain state information data of each SDN switch; packaging a private Ethernet type 0x9944 message into a Packet-out message of an OpenFlow standard through the controller, and sending the Packet-out message to all port devices of which the SDN switch port states are open; enabling the SDN switch port to receive the 0x9944 message, reassemble the 0x9944 message, and send the 0x9944 message to an adjacent SDN switch; S3, when the adjacent SDN switches in the step S3 receive the 0x9944 message, packaging the 0x9944 message into an Openflow standard Packet-in message, and sending the Openflow standard Packet-in message to the controller; using the packet-in message packaged with the 0x9944 message sent by the SDN switch for obtaining the information of port equipment through which the message passes so as to complete the link discovery of the SDN optical line terminals. According to the technical scheme, the network topology discovery method based on the SDN is low in message analysis difficulty, high in speed, high in expandability and capable of customizing a topology detection mode, and the discovery efficiency of the network topology discovery method based on the SDN is greatly improved.

Adaptation scheme for communications traffic

A communications network provides a carrier Ethernet service without requiring the client signal to be identified by an Ethertype in a carrier Ethernet frame. A plurality of differing types of client signals can thus be encapsulated within the same carrier Ethernet service channel by using a generic framing procedure adaptation layer. The client signals are adapted for encapsulation within the carrier Ethernet frames by mapping the client signal within a generic framing procedure adaptation layer signal and then by mapping the generic framing procedure adaptation layer signal into the carrier Ethernet signal. As the client signal is identified within said generic framing procedure signal only a generic framing signal Ethertype is required. The mapping protocol enables a single Ethernet frame to carry a plurality of client signals.

Techniques for enhancing the UDP network protocol to efficiently transmit large data units

Techniques for enhancing the UDP network protocol to efficiently transmit large data units are disclosed. A user datagram protocol (UDP) is a well-known protocol for transferring data between two nodes of a network. When data is too large to fit within a single UDP packet that can be transmitted between the two nodes, the data needs to be segmented and transmitted with multiple packets and reassembled on the receiving node. Techniques are disclosed herein, for example, for offloading such segmentation, transmission, and reassembly from the central processing units (CPUs) of the nodes. Such offloading is performed efficiently, for example, by repurposing legacy protocol fields used in UDP transmission such as the internet protocol (IP) identification (ID), time to live (TTL), type of service (TOS), and / or EtherType fields to encode information needed for efficient segmentation, out of order reception, and reassembly.
