	Common Open Policy Service - Wikipedia, the free encyclopedia
		The Common Open Policy Service (COPS) Protocol is part of the internet protocol suite as defined by the IETF RFC 2748.
		Policies are stored on servers, also known as Policy Decision Points (PDP), and are enforced on clients, also known as Policy Enforcement Points (PEP).
		The Provisioning Model uses the Policy Information Base as a repository of the policies.

	RFC 2748 - (rfc2748) - The COPS (Common Open Policy Service) Protocol (Site not responding. Last check: 2007-10-24)
		The policy protocol is designed to communicate self-identifying objects which contain the data necessary for identifying request states, establishing the context for a request, identifying the type of request, referencing previously installed requests, relaying policy decisions, reporting errors, providing message integrity, and transferring client specific/namespace information.
		Service discovery is outside the scope of this protocol, however.
		To ensure the client (PEP) is communicating with the correct policy server (PDP) requires authentication of the PEP and PDP using a shared secret, and consistent proof that the connection remains valid.

	COPS - a Whatis.com definition (Site not responding. Last check: 2007-10-24)
		COPS (Common Open Policy Service Protocol) is a proposed standard protocol for exchanging network policy information between a policy decision point (PDP) in a network and policy enforcement points (PEPs) as part of overall Quality of Service (QoS) - the allocation of network traffic resources according to desired priorities of service.
		The policy decision point might be a network server controlled directly by the network administrator who enters policy statements about which kinds of traffic (voice, bulk data, video, teleconferencing, and so forth) should get the highest priority.
		The policy enforcement points might be routers or layer 3 switches that implement the policy choices as traffic moves through the network.

		Feedback policies, which define the necessary selection and linkages to usage feedback criteria, are included by the PDP in a Decision message to the PEP.
		The monitoring and recording of usage policies is subject to context switches in a manner similar to that of the enforcement policy.

		Overview The COPS protocol [COPS] is a client-server protocol intended for the communication of policy requests and decisions between a Policy Enforcement Point (PEP) and a Policy Decision Point (PDP).
		The model for policy out- sourcing, of which the COPS protocol provides one part, is described in [FRAMEWORK].
		Other mechanisms for achieving this function without SNMP configuration might include use of the Service Location Protocol [SRVLOC] although this is outside the scope of this memo and are not specified by the COPS protocol itself.

	Implementation and evaluation of the Common Open Policy Service (COPS) protocol and its use for policy provisioning
		When building systems that support these kind of services, it is desirable to have a standardised protocol to configure nodes in the network to meet ordered policies.
		COPS, Common Open Policy Service, is the name of a new extensible base protocol designed for this purpose.
		The extension COPS-PR, COPS usage for Policy Provisioning, is used for provisioning policies on the nodes of a network.

		The Common Open Policy Service (COPS) is a relatively new protocol that allows router and layer 3 switches to get QoS policy information from the network policy server.

		The various types of this object are required for requests, and used in reports and opens when required.
		Given the stateful nature of COPS, it is important that when a request state is finally removed from the PEP, a DRQ message for this request state is sent to the PDP so the corresponding state may likewise be removed on the PDP.
		This message indicates that the remote PDP wishes the client (which appears in the common header) to re-send its state.

		We propose a taxonomy of policy architectures to classify the various feasible architectures into distinct categories.
		In general, average service availability for the PBNM system improved as the cluster size increased, with decreased COPS connection overhead (the tradeoff is increased unpredictability, longer response time, and resource requirements at intermediate nodes to support larger clusters).
		We were also able to determine that, for a given cluster size, our proposed delegation scheme resulted in a 10 to 25% improvement in service availability.

	Signaled QoS (Using Resource Reservation Protocol) [QoS Signaling] - Cisco Systems
		The Internet boom was peaking, with many Service Providers and Enterprises flush with funds; also the additional bandwidth was perceived as cheaper than QoS deployment.
		Admission control implies the ability to have a policy mechanism, which can essentially provide for services such as "Subscriber A gets only 100Kbps", while "Subscriber B gets only 80Kbps".
		To put it simply, not only is Cisco inventing the technology that enables new Internet services, but we believe in the value add of the technology, and use it to change the way we work, live, play and learn.
