In this implementation, each router within the network participates in the virtual routing environment in a peer-based fashion. While simple to deploy and appropriate for small to medium enterprises and shared data centers, VRF Lite does not scale to the size required by global enterprises or large carriers, as there is the need to implement ...
Dial on Demand Routing (DDR) is a routing technique where a network connection to a remote site is established only when needed. In other words, if the router tries to send out data and the connection is off, then the router will automatically establish a connection, send the information, and close the connection when no more data needs to be sent.
Port triggering is a configuration option on a NAT-enabled router that controls communication between internal and external host machines in an IP network. It is similar to port forwarding in that it enables incoming traffic to be forwarded to a specific internal host machine, although the forwarded port is not open permanently and the target internal host machine is chosen dynamically.
Vyatta is a software-based virtual router, virtual firewall and VPN product for Internet Protocol networks (IPv4 and IPv6). A free download of Vyatta has been available since March 2006. The system is a specialized Debian-based Linux distribution with networking applications such as Quagga, OpenVPN, and many others.
Using this technology, a system administrator can configure systems physically attached to the same local network into separate virtual networks. Conversely, an administrator can combine systems on separate local area networks (LANs) into a single VLAN spanning segments of a large network.
CWMP is a bidirectional SOAP- and HTTP-based protocol, and provides the communication between a CPE and auto configuration servers (ACS). The protocol addresses the growing number of different Internet access devices such as modems, routers, gateways, as well as end-user devices which connect to the Internet, such as set-top boxes, and VoIP-phones.
The virtual router is assigned to act as a default gateway of participating hosts, instead of a physical router. If the physical router that is routing packets on behalf of the virtual router fails, another physical router is selected to automatically replace it. The physical router that is forwarding packets at any given time is called the ...
Virtual network device, which allows a container to have its own IP addresses, as well as a set of netfilter (iptables), and routing rules. Devices If needed, any container can be granted access to real devices like network interfaces, serial ports, disk partitions, etc. IPC objects Shared memory, semaphores, messages.
