All rights reserved © 2006, Alcatel Page 9 Benefits of Distributed ABG Architecture Secure (Overlay) network extended to the Access Nodes QoS control extended to Access and Aggregation Network (End-2-End) Shaping at ingress of the NAP network, limiting the upstream load on the aggregation part of the network Possible local management of line capacity Protect BC of DoS attacks NW access. by limiting initial Upstream signalling rate in ABG. Better Scalability (smaller number of users per ABG ) Robustness (SPOF for far less users than ABG at edge) Potential Cost reduction (if integrated on existing AN hardware and BC in Sx)
All rights reserved © 2006, Alcatel Page 10 Challenges of Distributed ABG Session setup and signalling flows Communication between ABG and BC and Interaction with signalling ! Via MIDCOM protocol ? (Diameter / Megaco) Many parameters to be transferred – Ping Pong over A&A NW – Timing issues ? Integration into Access Nodes Optimal integration should not rely on use of dedicated resources (blade, NP…) Should be smartly integrated with existing designs to save cost, space resources Initiatisation, Configuration of ABG Need to configure ABG to allow first signalling at limited rate. Based on Dest of Border Controller Major
