 | | As mentioned in the beginning of the chapter, SVR3, where TLI was first introduced, did not provide a network transport. Thus, vendors who adopted SVR3 as their base operating system had to “graft” their existing transport layers onto TLI. Most vendors did this the same way—they made use of the existing data structures and library routines provided by their socket interface (described in Chapter 14, Networking With Sockets), making only minor changes to support the differences between sockets and TLI. | |
