same level of improvement as Ethernet. Ethernet??™s capabilities thus became much
more formidable than the other LAN technologies in a relatively short time, and to its
credit, Ethernet has continued to maintain this pace of innovation.
Standardization As shown previously in Table 1.1, innovations in Ethernet technology
were quickly standardized. Manufacturers could incorporate these new features
and bring them to market relatively quickly (see ???Intense Competition???).
