摘要:

由于服务的可用性或可负担性,数十亿人仍然无法上网。在本文中,我们提出了岩浆,一个开放和灵活的系统,用于建立低成本的无线接入网络。Magma旨在连接由于人口密度低或收入水平等问题而难以获得运营商经济效益的用户,同时保留蜂窝网络中预期的功能,如认证和计费策略。为了实现这一点,与传统的蜂窝网络相比,Magma采用了一种广泛利用互联网设计模式的方法,在边缘终止接入网络特定的协议,并将接入网络从核心架构中抽象出来。这一决定使Magma能够使用SDN(软件定义网络)原则重构无线核心,并利用现代分布式系统的其他技术。通过这样做,Magma降低了网络运营商的成本和运营复杂性,同时实现了弹性、可扩展性和丰富的策略支持。

英文摘要:

Billions of people remain without Internet access due to availability or affordability of service. In this paper, we present Magma, an open and flexible system for building low-cost wireless access networks. Magma aims to connect users where operator economics are difficult due to issues such as low population density or income levels, while preserving features expected in cellular networks such as authentication and billing policies. To achieve this, and in contrast to traditional cellular networks, Magma adopts an approach that extensively leverages Internet design patterns, terminating access network-specific protocols at the edge and abstracting the access network from the core architecture. This decision allows Magma to refactor the wireless core using SDN (software-defined networking) principles and leverage other techniques from modern distributed systems. In doing so, Magma lowers cost and operational complexity for network operators while achieving resilience, scalability, and rich policy support.
