Transmitting message prior to transmitting encapsulated packets to assist link partner in decapsulating packets

摘要

A network device includes a first circuit configured to generate a plurality of packets, and insert, in each of the plurality of packets, a different value for a count. A second circuit receives one or more of the plurality of packets. A third circuit generates a plurality of seeds. Each of the plurality of seeds is based on (i) a predetermined key, (ii) an address of the network device, and (iii) a predetermined value for the count. A fourth circuit encapsulates each of the plurality of packets using one of the plurality of seeds generated based on the value for the count in the respective one of the plurality of packets. A fifth circuit sends a message comprising (i) the address of the network device and (ii) the predetermined value for the count, and sends, subsequent to sending the message, the plurality of encapsulated packets.

1. A network device comprising:
a first circuit configured to receive one or more of a plurality of first packets from a host unit or a processor of the network device; a second circuit configured to
generate a plurality of second packets based on the plurality of first packets, and insert, in each of the plurality of second packets, a different value for a count; a third circuit configured to
generate a plurality of seeds,wherein each of the plurality of seeds is based on (i) a first predetermined key, (ii) an address of the network device, and (iii) a predetermined value for the count; a fourth circuit configured to encapsulate each of the plurality of second packets using one of the plurality of seeds generated based on the value for the count in the respective one of the plurality of second packets; and a fifth circuit configured to
send to an antenna of the network device a message comprising (i) the address of the network device and (ii) the predetermined value for the count; andsend to the antenna, subsequent to sending the message, the plurality of encapsulated second packets.
