This document discusses the security issues with current TCP/IP network architectures and proposes an alternative called UETS (Universal Ethernet Transport System). The key points are: - TCP/IP networks were designed decades ago without security in mind and now support many insecure devices and applications. This has led to complex add-on security measures over time. - UETS proposes using circuit switching at the Ethernet layer instead of TCP/IP to provide secure communications without changes to applications or devices. It would eliminate issues like spoofing and intercepting traffic. - UETS claims to radically improve security while maintaining compatibility with existing IP networks and applications, but removing complexity. The document argues it is time for a change in approach to better handle
