Abstract
Bond is a message-oriented middleware for network computing on a grid of autonomous
nodes. It consists of a distributed object communication fabric, servers, and agents. Core
servers are permanent objects providing services such as directory service, dispatching,
authentication, monitoring, and others. The Bond system monitor is responsible for
starting up core servers, keeping them running, and balancing the load among them. In
this paper, we discuss the remote server start-up and the executables failure detection
functions of the monitor and present the backup monitor.

1. Abbreviations and terms
Backup system monitor: core server; it takes control of the system when
the primary system monitor fails.
Shadow of a Bond object: abstraction supporting communication with a
remote object. A shadow is a local object acting as a proxy for theremote object, like CORBA’s stubs.
DSVN – Directory Server Virtual Network: collection of shadows of
directory servers. This object allows any server to communicate withthe directory servers.
Workspace: a container object. It provides references to a subset of
local objects.
Monitor-info object: an object that provides information to the system
monitor. This object is created at the workspace creation time.
Sub-protocol: sub-set of KQML messages used by objects to implement
different functions. It is equivalent to method invocation in CORBAor RMI.
Performative: component of a KQML message describing the action to be
performed.
