In the book Software Architecture in Practice by Bass et al., it is mentioned:
The broker pattern defines a runtime component, called a broker, that mediates the communication between a number of cllents and servers.
The original version of the broker pattern, as documented by Gamma, Helm, Johnson, and Vlissides [Gamma 94], is given in Figure 13.6.
I don't find the Design Pattern book by Gamma et al. includes a pattern called Broker. Is Broker mentioned in Design Patterns by Gamma et al.?
I see Broker is listed as an architectural pattern in Wikipedia. Is Broker a design pattern or an architectural pattern?
