TL;DR: It is shown that, in the original proposal of the MetaRing protocol, the deadlines of real-time messages are not always satisfied, and this problem is solved by modifying MetaRing, which allows the development of a synchronous bandwidth allocation scheme.
Abstract: This paper focuses on access protocols for supporting real-time communications in a distributed system; specifically, we analyze the MetaRing protocol. MetaRing is a protocol, designed and prototyped to handle, in a local or metropolitan area environment, both periodic traffic with real-time constraints (synchronous traffic) and bursty data traffic with no delay constraints (asynchronous traffic). We show that, in the original proposal of the MetaRing protocol, the deadlines of real-time messages are not always satisfied. Through a performance study, we solve this problem modifying MetaRing. The properties of the modified version are fully proved. These properties allow the development of a synchronous bandwidth allocation scheme. With this allocation scheme, the modified version of MetaRing, is able to support distributed real-time applications.
