Protocol link layer

摘要

A link is a software abstraction that represents a direct connection between two CoCo nodes. The link layer detects the presence of neighboring devices and establishes links to them. A protocol abstraction layer converts data frames that arrive on network interfaces into packet objects used by the COCO Protocol Suite.

1. A secure communication system comprising:
a first network node that is configured to establish a secure communication link for sending packets to a second network node by:
computing a work token, the work token including at least a work token validity interval that defines a period of time that the work token is valid; andcommunicating from the first network node to the second network node the work token and a time stamp corresponding to a time that the work token was computed, wherein the work token validity interval is at least equal to a hello interval and is less than an acknowledgement interval.
