scenario: P1 and P2 are located on each selfish network, each with its own NAT/FW, And the NAT/FW deployed by the ISP exists, this is a typical multi-layer NAT/FW situation. NA and NB indicate the NAT/FW of P1 and P2 respectively, and NC indicates the NAT/FW of ISP. In this case, for P1 and P2, there are three different IP addresses and ports. See table 1.Table 1 three different IP addresses/ports of P1 and P2IP address/port \ node P1, P2 P1 P2Private Network Address/port 10.0.0.1: 4321 10.1.1.

In practice, we usually put HTTPS and SSL protocol together; In fact, the SSL protocol was the Netcape company's agreement in the middle of the 90 's, which developed itself to version 3.0. 1999 the agreement was taken over by Itel, which was standardized and renamed TLS. It can be said that TLS 1.0 is the SSL 3.1 version. There

the Itel recommendation to set a TSS for each process. Instead, a TSS is set for each CPU, and the tr register saves the segment.Process switching concepts
According to Intel's design philosophy, the hardware context of process switching should be stored in TSS. This is acceptable because every process has TSS. However, in Linux, each CPU has a TSS, if all processes share one TSS, what is the hardware context protection during process switching? The
