A system is described for long-term controlled release delivery of a drug or a therapeutic agent. According to the invention, one or more drugs or therapeutic agents contained in microspheres are mixed with a temperature sensitive hydrogel which is then introduced directly to the desired situs of the drug or therapeutic agent. The temperature sensitive hydrogel may also contain a drug or a therapeutic agent, for example, a pain relieving drug, for a short-term controlled release. The temperature sensitive hydrogel is in liquid state at room temperature, but upon injection, shortly becomes gelatinous. This system is particularly suitable for treatment of diseases, disorders, or conditions, for example, tumors, discogenic back pain, or arthritis, warranting localized administration of a drug or a therapeutic agent. In addition, the specification provides a method for production of a drug—or therapeutic agent-containing microspheres.

A method for video-on-demand (VoD) admission control at a network edge assigns to a triple-play network virtual topology lesser resources than there exists in a corresponding underlying physical link bandwidth. This prevents video-on-demand (VoD) starvation of data-class traffic. At least one policy enforcement point (PEP) is attached to an edge of the network, providing for autonomous short-term, application-aware controls to be applied to corresponding network ingress traffic, and also providing for long-term controls on corresponding network ingress traffic. The network ingress traffic to the network comes under management when the traffic nears or exceeds network capacity. It is enabled to do so by computations of current network routing topology and bandwidth reservations. Path tables are used to calculate if a PEP may admit more, or must shed, sessions/calls to maintain service for other existing application traffic. The PEP and a session/call admission controller (S/CAC) may be independently located within the topology of the network, and together implement admission controls that differentiate between triple-play video, voice, and data traffic classes.

An advanced bandwidth manager (ABM) comprises a session/call admission controller (S/CAC) to manage network ingress traffic when a packet-switched network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. Ever-changing network topology information is gathered from remote listeners about how traffic is being routed through various parts of the network. These reports are harmonized to build a single view of the network topology, and the point-to-point connections are abstracted into path tables. Autonomous policy enforcement points (PEP's) provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. The S/CAC uses the path tables constructed to calculate whether the PEP's can admit more or should shed sessions/calls to keep service up for all existing application traffic. Long-term controls are periodically downloaded as admission tables from the S/CAC to the PEP's.

An auditing function detects and corrects reservation and routing topology map errors by monitoring the operation of an advanced bandwidth manager (ABM). A session/call admission controller (S/CAC) attached to a network manages loading with policy enforcement points (PEP's) when the network nears or exceeds its capacity. Ever-changing network topology information is monitored, modeled, and analyzed from remote listeners. A correct model of how traffic is being routed through various parts of the network is critical to admission control. The PEP's at the network edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. The S/CAC uses the path tables to calculate whether particular PEP's can admit more traffic, or should they shed sessions/calls to keep service up for the existing application traffic. Long-term controls are periodically downloaded as admission tables from the S/CAC to the PEP's.
