“Mobile” Your Networks It’s Changing Fast…

Service Provider Trends and the Impact on our Networks


Top 5 觀察趨勢

1. 頻寬 , 頻寬 , 頻寬

2. IP 世界的 OPEX

3. IP 是生活必需品

4. 您是生活大師

5. 跨業結合

趨勢 #1: 頻寬 , 頻寬 , 頻寬

WITHOUT Video impact!


Bursty 流量才正常



Why does the network need to be deterministic?

20Mbps per Home

所有關鍵應用 ( 包含語音及視訊 ) 均會移植至 IP


傳輸層較少被討論

多數設備供應商只討論控制及服務層只簡單假設傳輸層能提供上層所需的服務品質

但是… .. 　，傳統 IP 不能提供

• 端到端（ End-to-End) 效能及品質保證• 高穩定度• 高安全性• 高度虛擬化

• 跨部門及新事業需要網路的密集支援

• 傳統 IP 不是電信等級


MPLS 強化了 IP
