Foil 25 Switched Networks

From MultiCast Technologies and Rationale Large Web Application Class, CPS600/640 Fall 1997 -- Fall Semester 97. by Marek Podgorny * See also color IMAGE
What are the challenges?
  • Interoperability: legacy (hub/router) networks have to coexist with switched networks
  • Switching capabilities must be implemented at both layer 2 and layer 3 of the OSI model (multilayer switching)
  • LAN emulation must become commonplace - it isn't now
  • Or, network layer protocols must be modified to operate directly over ATM in native (AAL) mode (RFC 1577). This, BTW, would make ATM native QoS guarantees available for higher level protocols
