All Controller (PEC) configuration data and the master copy of the information store will be consigned to this amachine, You can only have one PEC per enterprise network, All other MSMQ installations will work only if they join @ PEC already on the network. PECs double as a PSC. Microsoft SQL Serveris required for this installation. Prichary Site Controller A PSG mustexist for every MSMO site installation. Sites are a collection of MSMQ installa- YPSC tions that represent a location, Communication bolwech computers in a site will be fast and efficient because of the short distarice between each client, Microsoft SQL Server is required for this installation Backup Site Controller A BSC stores backup information for a PEC or PSC. When a PEC or PSC fails, the BSC tem- (BSC) poranily hillsin for the failed server Microsoft SQL Server is required for this installation. Routing Server Routing Servers route MSMO information through the network. This installation doesn't require Microsoft SQL Server, and should only be used on a network with high MSMQ traffic. Independent Client Independent Clients maintain their own queues. Independent Clients send and receive messages while they aren't on the network. They're useful for laptops and other servers that might be disconnected from the network for any period of time. Microsoft SQL Server isn't required for this installation Dependant Client Dependent Clients are lie thinnest sort of MSMQ client available. The server (PEC, PSC, BSCYete l'supplies all MSMQ services,Up to 15 Dependent Clients can be supported by a server. This installation requires a network connection to a server, Microsoft SQL Server isn't required for this installation RAS Connectivity Service "The RAS Connectivity Service can be best compared to a proxy or forwarding service, This service enables RAS clients (most likely on Independent Client) to send and receive mes- soges trem computers other than the RAS server.
