19. What is IP Switching?
20. IP Switching IP Applications with ATM Performance and Quality of Service IP Router ATM Switch IP Switch IP Software ATM Forum Software IP Software Processor ATM HW ATM HW IP Switching combines the proven functionality of IP with the hardware switching speed of ATM
21. IP Switch Operation Initial Path ❶ IP packets are forwarded hop-by-hop using a default virtual channel (VC). ATM cells are reassembled into IP packets at each hop. The IP Switch Controller makes a flow classification decision. IP Switch IP Switch Controller Upstream Node ❶ ATM Cells VPI/VCI = 0/15 ATM Fabric Downstream Node ATM Cells VPI/VCI = 0/15
22. IP Switch Operation Controller Labels a Selected Flow IP Switch Controller sends an IFMP message to the upstream node ❷ to use a new VC for the selected flow. ❸ Traffic for the selected flow begins to flow on the new VC — the upstream flow is labeled. ❷ Upstream Node ❸ ATM Cells VPI/VCI = 0/X IP Switch IP Switch Controller ATM Fabric Downstream Node
23. IP Switch Operation Downstream Node Also Labels Flow ❹ Downstream node also sends an IFMP request for a new VC. Switch sends traffic for that flow to the downstream node on the new VC — ❺ IP the downstream flow is labeled. IP Switch IP Switch Controller Upstream Node ATM Cells VPI/VCI = 0/X ATM Fabric ❹ Downstream Node ❺ ATM Cells VPI/VCI = 0/Y
24. IP Switch Operation IP Flows at ATM Fabric Speeds! ❻ Incoming labeled flow switched through to outgoing labeled flow . “Cut-through” operation completed for flow-oriented traffic. IP Switch IP Switch Controller Upstream Node ❻ ATM Cells VPI/VCI = 0/X ATM Fabric Downstream Node ❻ ATM Cells VPI/VCI = 0/Y Port VPI/VCI Port VPI/VCI 1 0/X 2 0/Y
25. IP Switching Protocols GSMP RFC1987 IP Switch Controller Upstream Node General Switch Management Protocol Downstream Node ATM Fabric Ipsilon Flow Management Protocol Ipsilon Flow Management Protocol IFMP RFC1953 Protocol specifications available as RFC1953, RFC1954, and RFC1987. Reference implementations available. GSMP Simple protocol that provides call setup, tear-down, and call status Less than 2,000 lines of code Capable of operating with any ATM switch IFMP Protocol between multiple IP Switches or hosts Protocol used to send flow redirection messages

28. ATM Forum Complexity Making the Easy Difficult Steps Required to Build a LANE Connection Note: Picture and text from ATM vendor advertisement © 3Com Corporation 1996 1. First the network software in the PC must locate the server. To determine the server’s MAC address, the PC broadcasts an ARP (Address Resolution Protocol) request containing the server’s IP address. This is standard procedure in any IP network. 2. The ARP request reaches the LAN switch over the Ethernet segment. The LEC in the LAN switch forwards the broadcast packet to the BUS. 3. The BUS sends the ARP request to all members of the emulated LAN over a point-to-multipoint VC. 4. The server receives the ARP request and recognizes its own IP address. In response, it puts its own MAC address into an ARP reply addressed to the PC’s MAC address. There isn’t a direct VC to the LAN switch yet, so the server’s LEC sends the ARP reply to the BUS. 5. The BUS forwards the ARP reply to the LAN switch, which relays it to the PC over the Ethernet segment. 6. The PC now has the MAC address of the server and begins sending file transfer packets. 7. Meanwhile, the server’s LEC sets up a direct virtual circuit to the LAN switch. It begins by sending a LE-ARP request to the LES, asking for the ATM address that corresponds to the PC’s MAC address. 8. The LES can’t find the PC’s MAC address in its look-up table because the PC is hidden behind the LAN switch. So the LES multicasts the LE-ARP request to all LECs. 9. The LAN-switch LEC receives the LE-ARP request and recognizes the PC’s MAC address. 10. The LAN-switch LEC puts its own ATM address into a LE-ARP reply and sends it back to the LES. 11. The LES multicasts the LE-ARP reply to all members of the emulated LAN. 12. The server’s LEC receives the LE-ARP reply, extracts the LAN switch’s ATM address and signals for a direct VC to the LAN switch. 13. The ATM backbone switches set up a direct virtual circuit between the server and the LAN switch. 14. File transfer traffic begins to flow directly from PC to server.
29. IP Switching Flow Classification Flows consist of multiple packets that share, for example, the same source/destination addresses, type of service, protocol Long-lived flows are ideal for cut-through switching Short-lived transactions are ideal for datagram forwarding Flow-Oriented Traffic Short-Lived Traffic File transfer (FTP) File sharing (NFS) Web service (HTTP) Web image downloads Multimedia audio/video Name look-up (DNS) Network Time Protocol Email (SMTP) POP SNMP
