A multimedia visual progress indication system that provides a trick play bar that is overlaid onto the program material or displayed on a dedicated display. A cache bar inside of the trick play bar indicates the length of a recording session or the length of stored program material and expands to the right when material is being recorded. Every half hour (or selected increment), the cache bar slides to the left. Time marks are displayed inside the trick play bar giving the user a visual reference point from which to judge the current time and visual time reference points. The time marks are in any increment of time needed. The total length of the stored program material or next time or counter increment in the recording cycle is displayed on the right hand end of the trick play bar. A position indicator moves within the trick play bar and tells the user visually where his current position is within the program material. A slider moves along the trick play bar and on top of the cache bar and is linked to the position indicator and can be moved anywhere within the cache bar by the user. The slider displays the numeric time or counter mark of the current position. A mode indicator is positioned below the slider and follows the slider's movement and displays whether the user is in play, record, pause, slow play, fast play, fast forward (1×, 2×, and 3×), slow reverse play, slow reverse, and fast reverse (1×, 2×, and 3×) modes. The 1×, 2×, and 3× speeds are adjustable by the system to be any variable desired (e.g., 2×, 16×, and 32×). The trick play bar and its associated components are displayed for a predetermined time period when overlaid onto the program material.

A multi-stratum multi-timescale control for self-governing networks provides automatic adaptation to temporal and spatial traffic changes and to network state changes. Microsecond timescale reacting through the routing function, a facet of the lowest stratum, allows a source node to choose the best available route from a sorted list of routes, and to collect information on the state of these routes. Millisecond timescale correcting through the resource allocation function, a facet of the intermediate stratum, allows the network to correct resource allocations based on requirements calculated by the routing function. Long-term provisioning through the provisioning function at the higher stratum allows the network to recommend resource augmentations, based on requirements reported by the resource allocation function. The control is implemented in the network through coordination across edge node controllers, core node controllers, and network controllers. Metrics based on automated measurements of network performance are used by the control to adjust network resources. The Routing index is collected by the routing function and is the average rank of the selected route within a route-set. The routing function also collects measurements on route Constituent Traffic, which quantifies traffic in each of three categories: (carried) first-class, (carried) secondary, and rejected. The Resource Allocation Index is a metric collected by the resource allocation function. It quantifies the number of failures in re-allocating resources. In another aspect of this invention, a provisioning method is provided, which recommends appropriate link capacity increments based on the afore-mentioned Constituent Traffic measurements, and based on rules provided by the network operator.
