Network Enclaves consist of standalone assets that do not interact with other information systems or networks. A major difference between a DMZ or demilitarized zone and a network enclave is a DMZ allows inbound and outbound traffic access, where firewall boundaries are traversed. In an enclave, firewall boundaries are not traversed.
In telecommunications, Bearer Service or data service is a service that allows transmission of information signals between network interfaces. These services give the subscriber the capacity required to transmit appropriate signals between certain access points, i.e. user network interfaces.
Though the term, and the concept, originated in the wired telephony world, the discipline (if not the term) has expanded to other spheres in which the same sorts of work are done, including cable television and many aspects of Internet services and network operations. 'Ethernet OAM' is another recent concept in which the terminology is used.
Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks.
The basic differences among these service categories are described in the following sub-sections. [2] [3] These service categories provide a method to relate traffic characteristics and QoS requirements to network behaviour. The service categories are characterised as being real-time or non-real-time.
With the advent of the IN, most of these services (such as toll-free numbers and geographical number portability) were moved out of the core switch systems and into self-contained nodes, creating a modular and more secure network that allowed the service providers themselves to develop variations and value-added services to their networks ...
A point of delivery, or PoD, is "a module of network, compute, storage, and application components that work together to deliver networking services. The PoD is a repeatable design pattern, and its components maximize the modularity, scalability, and manageability of data centers." [1]
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
