Original Configuration of JGN2 TH-JP Circuit Foundry NI400 Foundry NI400 ATM 45Mbps GE VLAN (IEEE 802.1Q) Virtual Channel (VC) VLAN (IEEE 802.1Q) mapping (physical I/F: OC3) ThaiSarn and JGN2 are connected via ATM 45Mbps circuit terminated by Foundry NI400 switches with OC3 physical interfaces. VLANs are mapped to VCs (Virtual Channels) over ATM. As of Nov 2005 The problem was … NI400 cannot shape traffic in VP (Virtual Path) level, but VC level only. Without any traffic shaping, NI400 tried to send packets onto ATM circuit up to its physical bandwidth (155Mbps). This causes packet loss at carrier’s ATM switch. To avoid packet loss, we had to shape traffic per VC bases (set as CBR). This causes burdensome operation and inconvenience to users. CBR on each VLAN

Current Configuration of JGN2 TH-JP Circuit Foundry NI400 Foundry NI400 ATM 45Mbps GE VP-shaping VP-shaping capable ATM switches (NEC ATOMIS5S) are inserted between NI400 switches. ATOMIS switches shape traffic per VP-basis. Each VC is configured as UBR, not CBR. since Mar 22, 2006 NEC ATOMIS NEC ATOMIS UBR on each VLAN (physical I/F: OC3)

ATM Switch Installation Mar 21-22, Installation of new ATM switch (ATOMIS5S) at ThaiSarn NOC (Bangkok Thai Tower) - some performance tests
