Title: Explicit Allocation of Best-Effort Packet Delivery Service
Author: David D. Clark and Wenjia Fang
Reviewed by: Yuhan Cai
Main results of the paper:
， A framework called "allocated-capacity" for bandwidth allocation in congestion control is presented.
， The effectiveness of the framework is demonstrated by experimental results in a simulated environment.
Strengths of the paper:
， The framework presented is simple, scalable and flexible.
， Another two complementary (sender-based and receiver-based) methods for traffic control are also described.
， The same principle can also be applied to traditional applications such as file transfer and new applications such as real-time video.
， The framework allows users in different areas to make different capacity allocation decisions.
， The mechanism is also able to provide provisioning requirement information.
Key limitations:
， It focuses only on bulk-data transfers, but does not address the case where relatively small amount of data is transferred.
Relevance of the paper:
， A high degree of assurance is provided for the best-effort service over the current internet by the "allocated-capacity" framework.
Future work:
， It might be of interest to generalize the framework to other protocols.
