This re-emphasises the main reasons why organizations chose Token Ring back in the early days of networking. Corporations rejected Ethernet and instead chose Token Ring for the five key reasons shown on the slide, namely: * Token Ring’s in-built resilience and robustness - important for mission critical Token Ring networks. E.g. in a banking environment, if the network goes down and the bank is unable to process cheques then the performance of the business may be seriously impacted. * Token Ring’s superior manageability - important in large corporate networks with many thousands of users dispersed across a large area. * Companies like the performance of Token Ring - it scales extremely well as traffic loads increase allowing business critical applications to continue operating even under very heavy loads (c.f. Ethernet which can only scale to around 40-50% of the available bandwidth) * Compatibility with existing, SNA-based business applications * Future proof & investment protection - very important in large Token Ring networks where the investment in installed network equipment is very high

Token Ring is ready for multimedia applications. Multimedia on Ethernet will involve a new standard called 802.1q - this standard is not backwards compatible which means existing Ethernet networks will have to be completely upgrade e.g. new NICs, new hubs, new switches, … Why on Earth would anyone buy Ethernet???
