`
`Why Strings?
`
`Communications systems need to be:
`
`Dynamic: networks, media types and end points are
`unpredictable
`
`Distributed: content, resources and processing need to
`be distributed to maximum networked elements
`
`Efficient: managing communications must be efficient
`for everything from overloaded back-end systems to
`resource constrained clients

`
`A Traditional Video Player
`
`App
`
`1. Application has built in knowledge of devices
`2. Application features are tied together
`3. Application components are not reusable in other
`contexts at runtime
`4. Application cannot be decomposed and distributed

`
`
`Benefits Over Traditional Systems
`
`1. Device knowledge encapsulated in Beads
`2. Features are re-configurable at initialization
`or run time
`3. Network services are dynamically discovered
`4. Beads can be re-organized to create a
`distributed service
`5. Behavior can be modified without requiring
`new code

`
`
`
`Platform Independence
`
`• Interface Libraries provide access to external
`resources such as drivers, OS services and
`API
`• Operating System Abstraction Layer (OAL)
`provides abstraction from underlying Kernel
`services such as access to physical memory,
`CPU scheduling and locks
`• Strings manages scheduling, memory, timers
`and module loading for consistency across
`underlying platforms

`
`
`
`Beads
`
`• Software components that encapsulate
`algorithms.
`• Composed of a series of inputs and outputs
`• Beads provide a service that when described
`to the core system can be used to create
`higher level services (features) on the fly.
`• Focused only on encapsulating internal
`algorithms not external relationships.

`
`
`
`Labels
`
`• Labels are names used to tag information
`with query-able attributes.
`• Labels are used to define inputs and outputs
`to Beads.
`• Labels can be arbitrarily rich.
`• A registry in Strings is used to name space
`created by the available labels.

`
`
`
`Mapping
`
`• The Mapping Engineis a system level service for
`determining what Beads are necessary to handle a
`given type of media within a given set of constraints.
`• The Mapis a set of rules to impose upon the graph
`search the Mapping Engine performs.
`• Mapping is adaptive to the changing environment.
`• Mapping is rules based meaning the determination of
`Beads can be influenced by external rules (security,
`network bandwidth etc..)

`
`
`
`Paths
`
`• Paths capture the global context of stream of
`data through a set of Beads.
`• Paths can be extended across machines
`boundaries.
`• Paths are efficient abstractions for managing
`streams of data.
`• Paths are dynamically constructed and
`destructed.

`
`
`
`Beads
`
`• Beads are autonomous units of
`functionality which provide a well-
`defined service.
`• The service provided by a Bead is
`described by its Schema.
`• Instantiating a Bead requires
`configuring it to participate in higher-
`level services called Features.

`
`
`
`Features
`
`• A Feature is a collection of Beads and/or
`other Features
`• Features are implemented in terms of the
`services provided by the elements (Beads &
`sub-Features) of the Feature.
`• The service provided by a Feature can be
`described by the same Schema as the
`Schema used for a Bead
`• Feature can be thought of as a composite
`Bead.

`
`
`
`Service
`
`• Features can be configured in such a
`way as to exported to the network
`• Other hosts in the network can leverage
`that Feature either at runtime, via
`remote mapping
`• …or at configuration time in the
`construction of higher level Features.
