UNIFIED NETWORK SYSTEMS
CORE NETWORK SYSTEM
Multi-Pipeline Internet Distribution (Multiple ISPs Adapted to IXPs)
Our Internet Service System Architecture has been peered with several local ISPs that creates an Internet exchange Point (IXPs) and transformed into a unified network within our core system. This unified network is a vital element in our core system which provide numerous PoP links as our local loop for the last mile connectivity distributions. The larger the network, the more points of presence you generally had.
By having this multi-pipeline interconnectivity in one facility, networks reduce the portion of the total traffic which must be delivered via transit with our peering partner. Moreover, our networks can cost-effectively gain lower-latency connections than if they had to reach those networks via multiple transit hops. The availability of multiple peering’s also increases network performance and transit path resiliency.
CONSUL NETWORK SYSTEM ARCHITECTURE
Our new approach in building Internet Point of Presence via several peering partners would create an algorithm of Packet Switching Network (PSN) with Open Shortest Path First (OSPF) protocol that bring application and data closer to users and create a more resilient distributed network. In this connection, the distance between the end-user and the internet backbone causes latency & minimize hops that impacts application performance and content delivery.
FEATURES OF UNIFIED NETWORK SYSTEMS
A. Bandwidth Aggregation
The Multichannel VPN Hub is the core of the ConsulBoard technology for bandwidth aggregation. With this device, several broadband lines can be combined into a single, highly available joint line. Unlike load balancing which can only distribute load to several WAN links, real bonding of all connections available is realized here.
ConsulBoard can combine all different types of access media, be they DSL / 3G/4G/5G/ Satellite internet. The LAN sees these connections as one single line providing the accumulated up – and downstream of the different links even for single downloads.
Remote Station Principle
ConsulBoard uses an exceptional VPN tunnel technique with a star topology for secure and fast sites, facility and vehicle linkage. For this purpose, the integration of two different devices is needed: A Multichannel VPN Hub establishes an encrypted VPN tunnel to a single central remote station, the Wi-Tek Multichannel VPN Hub, via each Internet line available. These VPN tunnels are then bundled into one tunnel through which the data is then transferred.
The Multichannel VPN Hub is located in our data center and acts as an internet exchange point (IXP). Data targeted at another company site will be forwarded through the respective VPN tunnel; data targeted at the public Internet will be decrypted and forwarded to its destination. The VPN Hub provides secure and quick communication between different Multichannel VPN Routers but it also serves as pivotal exchange point between the encrypted VPN and the public Internet.
The data stream from the LAN is encrypted by the Multichannel VPN Router and distributed onto the Internet connections (DSL, 4G, SatLink & FTTh). The encrypted and fragmented data passes the networks of the utilized ISPs and reaches the Multichannel VPN Hub in the data center, which in turn decrypts the data stream and reassembles it correctly- Afterwards, the data stream is forwarded to its actual destination on the Internet. The same goes for the opposite direction. Here, the Hub encrypts the data stream, while the VPN Router decrypts it.
Benefits of DSL Bonding:
• Low line prices instead of expensive leased lines or MPLS connections
• Low latency – the best medium for interactive applications and video streaming.
• Maximum bandwidth with the unique ConsulBoard bonding
• High reliability by bonding different DSL providers and further WAN media
• Connection backup by additional bonding of cellular radio
• Several low-priced consumer lines become a professional site-to-site connection which costs less than leased lines or MPLS infrastructures.
• Using the ConsulBoard VPN tunnel, the DSL connection becomes available via a static IP address.
B. Mesh Network Topology
Mesh network topology is one of the key network architectures in which devices are connected with many redundant interconnections between network nodes such as routers and switches. As our Internet point of presence has been spread out this make our Mesh systems network creates a big advantages to communicate to every node how to link with the access point and how a node should direct traffic that is trying to go somewhere.
When we are routing a message in a mesh network, it propagates a predefined path, hopping from node to node until it reaches its destination. In order to establish these routes and ensure that the paths are available, the network needs to be continuously connected and configuring itself. In other words, it has to constantly work to find broken paths and create self-healing algorithms to build route tables.
This creates multiple routes for information between pairs of users, increasing the resilience of the network in case of a failure of a node or connection. In a full mesh topology, each network node is connected directly to each of the others. The decision of which nodes to mesh depends on factors like the traffic pattern of the network overall and the extent to which nodes or connections are at risk of failure.
C. Policy Base Routing
Policy-based routing is one of the powerful tools in our unified network system that could easily control the specific paths of network traffic either from the downstream and upstream direction. This tool provides a forwarding and routing data packets based on policies defined in our system network. The route map determines which packets are routed to a different device that we set. You might enable policy-based routing if you want certain packets to be routed some way other than the obvious shortest path. Applying the policies in this mechanism will be based on the selection of access list, packet size and the traffic flow direction with in the entire network.
D. Long Range Wireless Internet Backhauling
We used a variety of high carrier grade licensed microwave radio running in a multiple frequency licensed band that ensures the stability and reliability of long-distance wireless connection and transmission of data. These super-high-frequency radios extend private fiber network backbones between buildings or towers using “air fiber” by providing a “full-duplex” solution.
This full-duplex capability is accomplished using the Time Division Multiplex Access (TDMA) protocol, which coordinates transmitting or receiving. The time on the channel is divided into time slots. A base station node coordinates the allocated time slots of the nodes of the network to which they transmit, usually organized as a frame. The base station specifies in the beacon the frame organization and regularity, so each node follows the base station’s lead. Typically, the frame is organized as downlink (base station to node) and uplink (node to base station) time slots, with the base station being master controller. In some standards, uplink and downlink frames are different frequencies, and the slots might also be a separate channel.
E. Domestic Satellite Link Network
In today’s world of wireless communications, our celestial link is a great advantages in distributing a network communications to cover the interisland and less populated area of our country. As urban dwellers, we often overlook the role of satellite technology in providing vital communication links to remote areas where terrestrial networks are unavailable or out of reach. Despite the roll-out of terrestrial networks to many parts of our island, there are many regions that remain unconnected which rely on satellite connectivity. It is either physically not possible to connect users at the coastal area or in the remote area beside the mountain except via satellite or there is no business case to justify the costs to roll-out fiber to remote and sparsely populated areas. As such, satellite technology has a key role in enabling new applications for online learning and business processes that are making the Internet connection & communication a reality.
