A distributed ring call protection method and system
By parsing the resource identifier chain of RPC requests or MQ messages, the circular calls are proactively blocked, solving the problem of system resource exhaustion and cascading failures caused by the inability to identify and block circular calls in existing technologies, thus improving the stability and availability of distributed systems.

Abstract
本发明公开了一种分布式环状调用防护方法及系统，涉及分布式系统技术领域，分布式环状调用防护方法包括：当RPC请求或MQ消息进入当前服务节点时，从RPC请求的请求上下文或MQ消息的消息属性中解析资源标识链，资源标识链由RPC请求或MQ消息所属的业务处理链路中已被调用并执行了业务逻辑的服务节点所对应的资源标识按节点访问顺序拼接形成；若解析得到资源标识链且解析得到的资源标识链包含当前服务节点对应的资源标识，则判定处理RPC请求或MQ消息将导致形成环状调用，对RPC请求或MQ消息执行主动阻断操作。本发明可从根源上识别并阻止环状调用形成，实现了对分布式环状调用的精准、主动、高效防护。
