A routing boundary in which Exterior Gateway Protocols are predominantly used to pass routing information.
Determining and persistently maintaining connection information along the path of a connection, between source and destination.
An architectural model based on the hierarchical client-server flow model. In addition to the functions, features, and services being focused at server locations and client-server flows, they are also focused at the server-server flows.
A flow model that has the characteristics of a client-server flow model but that also has multiple layers, or tiers between servers.
When the management functions (monitoring, display, storage, and processing) are separated and placed on separate devices.
The degree of concentration of networks or traffic flows at interconnection points within the network, as well as the number of tiers of interconnection points within the network.
An indicator that the service request or requirement's performance characteristics are greater than a performance threshold determined for that network.
A network that typically has one or a few applications, users/groups, and/or devices whose performance requirements are significantly greater than other performance requirements for that network.
Model that focuses on identifying networks or parts of a network as general performance, as high performance, or as having components of both.
An estimate of the time threshold when users begin to perceive delay in the system.
When the data flows for network management follow the same network paths as the traffic flows for users and their applications.
The flow associated with a single session of an application.
Initial input to the requirements analysis process, consisting of the type of network project, scope of the architecture and design, initial architecture/design goals, and any outside forces acting on the network.
For network management, the set of tools and utilities needed to monitor and probe the network for management data.
Mechanisms that interconnect network technologies, including shared media, switching, bridging, and routing.
A quality-of-service mechanism that defines values and mechanisms for allocating resources to flows across the end-to-end path of the flow.
Applications that assume some timing relationship between source and destination while the application session is active, however, the timing relationship is not as strict as it is in real-time.
Applications in which the end-to-end or round-trip network delays are not the predominant delay for that application, but processing at the device or application component is the predominant delay.
Applications in which the end-to-end or round-trip network delays are the predominant delay for that application.
A user requirement for a response time from the system (as well as the network) that is on the order of the response times of users.
A balance to hierarchy in a network, interconnectivity is the degree of connections within the network at different levels in the design, to provide greater performance through parts of the network.
Routing protocols that communicate routing information primarily within an AS.
Architectural model that focuses on security and privacy, including the separation of users, devices, and applications based on secure access.
A protocol for providing authentication and encryption between devices at the network layer.
A set of mechanisms to configure, operate, manage, provision, and account for resources in the network that allocate performance to users, applications, and devices.
