Network Identifier: Defines the external network to which the Gateway GPRS Support Node (GGSN) is connected. Optionally, it may also include the service requested by the user. This part of the APN is mandatory; Operator Identifier: Defines the specific operator's packet domain network in which the GGSN is located. This part of the APN is optional.
Gateway Control Protocol Relationship. The media gateway control protocol architecture and its methodologies and programming interfaces are described in RFC 2805. [1]MGCP is a master-slave protocol in which media gateways (MGs) are controlled by a call control agent or softswitch.
A Wi-Fi Repeater. A wireless repeater (also called wireless range extender or wifi extender) is a device that takes an existing signal from a wireless router or wireless access point and rebroadcasts it to create a second network.
The Internet (or internet) [a] is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) [b] to communicate between networks and devices.
In the specific context of an MPLS-based virtual private network (VPN), LERs that function as ingress or egress routers to the VPN are often called provider edge (PE) routers. Devices that function only as transit routers are similarly called provider (P) routers. [14] The job of a P router is significantly easier than that of a PE router.
Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the ...
The architecture divides the functions required for the integration of traditional telecommunication networks and modern packet networks into several physical and logical components, notably the media gateway, the media gateway controller, and signaling gateways. The interaction between the media gateway and its controller is defined in the ...
