  1. End-to-End QoS With Budget-Based Management 資碩一 洪玠榮Jerome 學號:492515289

  2. Outline • Introduce • The concept of budget-based QoS • End-to-end QoS • The concept of budget allocation • To allocate the limited resource to satisfy all the requests as possible • The concept of revenue management • How to use the limited budget to obtain the maximum profit

  3. Introduce • ALL-IP network • QoS over All-IP network • End-to-End QoS

  4. Budget-Based QoS • 以預算為基礎的品質保證 • Budget • Delay bound • Jitter bound • Packet loss bound • 採用分層分權的方式將QoS管理權責以 budget 方式分散到每個網路元件 • 以budget滿足traffic的要求，以達到QoS服務品質的保證 • Reduce the manage complexity

  5. End-to-End QoS Architecture

  6. End-to-End QoS • User 要求 end-to-end QoS 保證 • 兩個端點間事實上是經過好幾個網路介接。 End-to-end是由好幾個網路介接而成，因此end-to-end QoS可由各個subnet的budget共同達成

  7. End-to-End QoS

  8. System Architecture • All-IP Network Architecture Model •  End-to-End QoS Model • Short Path Attribute

  9. All-IP Network Architecture Model 骨幹網路（Backbone） • a.       骨幹網路由核心網路（Core networks）相互連結組成。 • b.       骨幹網路之Edge router均稱為Border Gateway（BG）。 因此，Border Gateway為接取網路連接上骨幹網路之入口閘道器。 • c.       核心網路間以Internal domain Gateway（IG）互連成骨幹網路，Internal domain Gateway間則以Domain inter-connection link相連。核心網路之間不一定只有一條Domain inter-connection link，會依照實際的需求建置。 • d.       由於骨幹網路所需負載之交通流量相當繁重。因此，骨幹網路通常可提供較大之頻寬和較小之delay time[6]。 接取網路（Access Network） • a.       接取網路為直接提供服務給終端使用者的網路，可能為無線接取網路（ex. UMTS、GPRS、802.11）、固接式接取網路（Fixed network）或是其他類型之接取網路。 • b.       接取網路以Access Gateway（AG）連接骨幹網路上的Border Gateway，Access Gateway和Border Gateway間則以Access link相連。Access link通常只會有Alternative link作備援線路，因此，在本研究當中的架構模型，將會視為只有單一Access link。 • c.       接取網路由Network Access Server（NAS）負責連結至終端使用者。 • d.       由於接取網路所需負載之交通流量為局部的。因此相較於骨幹網路，接取網路通常只能提供較小之頻寬。
