Frequently Asked Questions
In computer networks, bandwidth is often used as a synonym for data transfer rate - the amount of data that can be carried from one point to another in a given time period. This kind of bandwidth is usually expressed in bits (of data) per second (bps).
Bandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link. Click here for more Info
Bandwidth Control by sharing of the existing Internet connection bandwidth and distributing it among all users and servers according to preset rules. Netwall implements the concept of integrated approach to monitoring and limiting corporate Internet traffic, and also to controlling the efficiency of the company's employees.
Sharing Internet Connection problem in Corporate. If you are sharing your internet connection , you will be in some problems. There's always in deparments(like Accounts,Sales,other) who uses up all bandwidth to download video's video sites like Youtube,porn using p2p,Download Heavy games or chating in facebook ,chating anywhere. But Your Organisation Boss not able to chat properly or send mail due to bandwidth utilisation by other departments. The best solution to this kind of problems is to use a Netwall which is capable of QoS (Quality of Service). Basically, this kind of software controls your traffic making sure everyone gets a fair share of bandwidth. Of course if you are the administrator, you can make your share a bigger one Find out how you can set up a network without blowing your budget.

A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. One common method of attack involves saturating the target machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately. An example of this occurred when Michael Jackson died in 2009. Websites such as Google and Twitter slowed down or even crashed.Many sites' servers thought the requests were from a virus or spyware trying to cause a Denial of Service attack, warning users that their queries looked like "automated requests from a computer virus or spyware application". Netwall Bandwidth Management software include protection for DOS attacks.
Where you keep all your Web page is called "hosting". Web Hosting that allows individuals and organizations to make their own website accessible via the World Wide Web.
Advanced Network Traffic shaping is the control of Internet or Intranet traffic optimize or guarantee performance, improve network latency, and/or increase usable bandwidth for some kinds of packets by delaying other kinds of services packets that meet certain criteria. If a link becomes saturated to the point where there is a significant level of contention (either upstream or downstream) latency can rise substantially. As a result, internet traffic shaping can be used to prevent this from occurring and keep latency in check with limits. Traffic shaping provides a means to control the volume of traffic being sent into a network in a specified period (bandwidth throttling), or the maximum rate (Bandwidth Management) at which the traffic is sent (rate limiting), or more complex criteria such as GCRA. This control can be deploying in many ways and for many reasons, however traffic shaping is always achieved by delaying packets. Traffic shaping is commonly applied at the network edges to control traffic entering the network, but can also be used by the traffic source (for example, computer or network card) or by an element in the network. Traffic policing is the distinct but related practice of packet dropping and packet marking by Linux advance Routing and Firewalling.
In simple words the FUP (Fair Usage Policy) means that even though you may subscribe to an unlimited broadband plan say for example 768 kbps unlimited per month, and if your usage is very high and crosses a certain cap as decided by the broadband provider your connection speed will then be reduced to 512 kbps for the remaining month.
A router is a device that analyzes the contents of data packets transmitted within a network or to another network.An ex. of a router is computer hardware that transfers Internet messages to a laptop in another room; a wireless router A router is connected to two or more data lines from different networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. The most familiar type of routers are home and small office routers .example of a router would be the owner's cable which connects to the Internet through an Internet service provider (ISP)
BGP is protocol that manages how packets are routed across the internet through the exchange of routing and reachability information between edge routers. BGP is most commonly used as an external routing protocol for large networks with multiple connections to the Internet. Companies or institutions that use BGP will have a unique autonomous system number that is exchanged with other BGP networks to create peering relationships with other autonomous systems. Through these partnerships, large networks and service providers provide BGP-controlled routes to, from, and through each other’s autonomous systems to give the Internet increased speed and efficiency, as well as a high level of redundancy.
PPPoE stands for Point-to-Point Protocol over Ethernet. It is a network protocol sometimes used by broadband Internet service Provide world wide.
Make sure that you have specified a valid DNS server in the router (in /ip dns or in /ppp profile the dns-server parameter).
A VLAN (virtual LAN) abstracts the idea of the local area network (LAN) by providing data link connectivity for a subnet. Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802
Network devices such as switches, hubs, bridges, workstations and servers connected to each other in the same network at a specific location are generally known as LANs. A LAN is also considered a broadcast domain. A VLAN allows several networks to work virtually as one LAN.
A network access server (NAS) is a computer server that enables an independent service provider (ISP) to provide connected customers with Internet access..Netwall NAS Support
