5 5 Rendezvous Network Server Glossary A active-active mode An operating mode in which two zones cooperate for fault tolerance, with each zone serving a distinct subset of clients. In each zone, one virtual router is in the master state. active-standby mode An operating mode in which two zones cooperate for fault tolerance, with one zone serving all clients, and the other zone ready to serve if the first zone becomes unavailable. In one zone, both virtual routers are in the master state. Upon recovery from failover, the zones are in active-standby mode. An administrative task can restore activeactive mode. active state The active state of a gateway daemon, in which it routes messages, establishes neighbor connections, and communicates on its local networks. See also, idle state. adapter The adapter module facilitates communication between applications that use TIBCO Rendezvous messages and applications that use TIBCO FTL messages. When configured and enabled, the adapter runs within an rvd service. B backup state An inactive state of a virtual router. See also, master state. D down state The inactive state of a VRRP VNIC. G gateway client An application that uses the Rendezvous API to connect to an rvd service at a virtual IP address (VIP). gateway daemon rvgd. Gateway daemons enable message exchange between clients of TIBCO Rendezvous Network Server and clients on other networks (including multicast networks).

6 6 gateway LAN A specialized local network of a gateway daemon. A gateway daemon connects to a gateway LAN as a client to an rvd process. That rvd process accepts client connections through a virtual IP address (VIP). global zone The default zone. See also zone, Rendezvous zone. I idle state The inactive state of a gateway daemon, in which you can configure it, but it cannot not route messages, establish neighbor connections, nor communicate on its local networks. See also, active state. M master control program (MCP) A service that monitors VNIC status and controls the states of Rendezvous services accordingly. master state The active state of a virtual router. At any moment, only one virtual router in a VRID group can be in the master state. See also, backup state. mode See operating mode. module TIBCO Rendezvous Network Server is sold as a software module, which you install on server-switch hardware. multicast client A client that connects to an rvd process on the same network as a zone s unique IP address (UIP). multicast LAN A local network of a gateway daemon (or of a routing daemon) on which clients communicate using network multicast. N neighbor Rendezvous routing daemons and gateway daemons can become neighbors. Neighbors can forward messages to one another.

7 7 neighbor network A network connected by a neighbor link to another router instance. O operating mode The various ways in which zones (along with their virtual routers and redundant services) cooperate to serve clients. See also active-active mode and active-standby mode. R remote daemon An rvd (or other Rendezvous daemon) process running on a different host machine than its clients. Rendezvous zone A zone configured as a Rendezvous virtual server. See also zone, global zone. reference configuration The zone administration utility outputs a verbose version of a zone s configuration. You may use it in place of your own configuration file. router 1. See virtual router. 2. A Rendezvous routing daemon, for example, rvrd, rvgd. 3. See router name. routing daemon rvrd. router name The name that identifies a routing table entry which is the basic building block of a Rendezvous routing system. You can define one or more router name instances within a gateway daemon. S service 1. A service or process within the operating system s Service Management Framework (SMF). 2. A Rendezvous service, specified by a network and a service port. service group A group of clients transports that communicate with one another over the same Rendezvous service.

8 8 service script A script that the operating system uses to start a service process. For example, the script rvd64_a.sh starts the rvd64 executable as a service. subject gating Determines the set of messages a gateway daemon (or a routing daemon) forwards. U unique IP address (UIP) Each Rendezvous zone exposes one unique IP address to the network, and uses it for administration, for multicast LAN traffic, and for communication among gateway daemon processes through neighbor links. up state The active state of a VRRP VNIC. V virtual IP address (VIP) The IP address that a VNIC presents to the network. Administrators reserve virtual IP addresses, and configure Rendezvous zones to use them. Virtual routers can share a virtual IP address such that only one of them at a time exposes the address to the network. virtual router Virtual routers coordinate using VRRP to manage redundant virtual IP addresses. VRID 1. Virtual router ID. 2. A group of virtual routers that have the same VRID, and manage redundancy for fault tolerance. VRRP Virtual Router Redundancy Protocol. VRRP VNIC VRRP-enabled Virtual Network Interface Card. When a VRRP VNIC is in the UP state, the corresponding virtual IP address (VIP) resolves to that VNIC. Z zone A virtual server (or virtual OS) with very low host OS resource requirements. See also global zone, Rendezvous zone. zone administration utility An executable utility that you can use to create, update, destroy or backup a Rendezvous zone.
