摘要

OPERA是最近引入的一个框架，它基于路径信息形式化路由规则。在IBGP和EBGP中使用的策略机制中添加了从OPERA派生的新规则，以提供路径之间的总排序，从而产生了基于OPERA的BGP (OBGP)。OBGP是一种基于IBGP和EBGP的完整的无环域间多径路由解决方案。事实证明，OBGP在任何时刻都是稳定的、无环路的。本文使用了IBGP和EBGP不收敛的著名系统示例来说明OBGP的好处。

Eliminating Routing Loops and Oscillations in BGP Using Total Ordering

OPERA is a framework recently introduced that formalizes routing etiquettes based on path information. New rules derived from OPERA to provide total ordering among paths are added to the policy mechanisms used in IBGP and EBGP, which results in OPERA-based BGP (OBGP). OBGP is a complete loop-free inter-domain multi-path routing solution based on IBGP and EBGP. OBGP is proven to be stable and loop-free at every instant. Well-known examples of systems in which IBGP and EBGP do not converge are used to illustrate the benefits of OBGP.
