Toward Fully-Shared Access: Designing ISP Service Plans Leveraging Excess Bandwidth Allocation

TL;DR

This paper explores designing flexible ISP service plans that leverage excess bandwidth allocation enabled by new traffic control schemes, aiming to improve resource utilization, revenue, and QoS in shared access networks.

Contribution

It proposes a practical framework for service plans that utilize excess bandwidth allocation, advancing towards fully-shared access networks.

Findings

Enhanced bandwidth utilization in shared access networks.

Potential increase in ISP revenue and subscriber QoS.

Feasibility of implementing flexible service plans with excess bandwidth allocation.

Abstract

Shaping subscriber traffic based on token bucket filter (TBF) by Internet service providers (ISPs) results in waste of network resources in shared access when there are few active subscribers, because it cannot allocate excess bandwidth in the long term. New traffic control schemes have been recently proposed to allocate excess bandwidth among active subscribers proportional to their token generation rates. In this paper we report the current status of our research on designing flexible yet practical service plans exploiting excess bandwidth allocation enabled by the new traffic control schemes in shared access networks, which are attractive to both ISP and its subscribers in terms of revenue and quality of service (QoS) and serve as a stepping stone to fully-shared access in the future.
