We survey transformer-inspired mechanisms—Flash-style IO-aware queuing, grouped subscriber routing, crossattention dispatch, mixture-of-experts selection, speculative earlyexit, ring attention, RMS-style normalization, and resilient external integrations—as applied to communication middleware. Weposition this stack against established systems (Kafka, Pulsar,NATS, RabbitMQ, Redis Streams, ZeroMQ, gRPC) and report aconsolidated empirical view: latency/throughput, ordering quality, anomaly compression, early-warning lead time, and crossdomain … Continue reading Attention Wasn’t All We Needed: A Survey of Transformer-Inspired Design in Communication Middleware
