G 1 Overview In a home or office environment users constantly have to transmit data to and from the Internet When too many are accessing the Internet at the same time service can slow to a crawl causing service interruptions and general frustration Quality of Service QoS is one of the ways BiGuard 50G can optimize the use of bandwidth ensuring a smooth and responsive Internet connection for all users G 2 What is Quality of Service QoS is a feature that prioritizes and guarantees bandwidth to achieve optimal service performance QoS can maximize the use of available network bandwidth by prioritizing time sensitive traffic to avoid latencies and delays By ensuring that time sensitive applications such as VoIP and streaming video get priority access to bandwidth users in both home and office environments can enjoy smooth and responsive data transmission no matter which applications they are running If you ve ever experienced slow Internet speeds due to other network users using bandwidth consuming applications like P2P you ll understand why QoS is such a breakthrough for home users and office users Billion makes itself unique by integrating QoS in its routers for both inbound and outbound traffic QoS helps users manage bandwidth and effectively prioritize data traffic It gives you full control over the traffic of any type of data Employed on DiffServ Differentiated Services architecture data traffic is given priority by

50. 1 Network Basics D 1 1 IP Addresses With the number of TCP IP networks interconnected across the globe ensuring that transmitted data reaches the correct destination requires each computer on the Internet has a unique identifier This identifier is known as the IP address The Internet Protocol IP uses a 32 bit address structure and the address is usually written in dot notation A typical IP address looks like this 198 25 12 8 The 32 bits of the address are subdivided into two parts The first part of the address identifies the network while the second part identifies the host node or station on the network How the address is divided depends on the address range and the application The five standard IP address classes each have different methods to determine the network and host sections of the address which makes multiple hosts on a network possible TCP IP software identifies each address class by reading a unique bit pattern that precedes each address type Once the address class has been recognized the software can then correctly determine the addresses host section With this structure IP addresses can uniquely identify each network and node D 1 1 1 Net mask With each address class the size of the two subdivided parts network address and host address is implied by the class A net mask associated with an IP address can also express this partitioning A net mask 32 bit quantity yields the network address when combine

53. A router is connected to at least two networks Usually this is a LAN and a WAN that is connected to an ISP network Routers are located at gateways the places where two or more networks connect Routers use headers and forwarding tables to determine the best path for forwarding the packets and they use protocols to communicate with each other and configure the best route between any two hosts Routers can vary in performance and scale the types of physical WAN connection they support and the number of routing protocols supported BiGuard 50G offers a convenient and powerful way for small to medium businesses to connect their networks D 2 2 Why use a Router While large bandwidth can easily and inexpensively be provided in a LAN having high bandwidth between a LAN and the Internet can be prohibitively expensive Because of this Internet access is usually done through a slower WAN link such as a cable or DSL modem To efficiently use this slower connection a router acts as a mechanism for selecting and transmitting data meant for the Internet By using a router organizations can enjoy relatively inexpensive Internet access while maintaining a high speed local area network D 2 3 Routing Information Protocol RIP Routing Information Protocol RIP is an interior gateway protocol that specifies how routers exchange routing table information Routers periodically update each other with RIP changing their routing tables when neces

Before You Begin BiGuard 50G is a flexible and powerful networking device To simplify the configuration process and increase the efficiency of your network consider the following items before setting up your network for the first time 1 Plan your network Decide whether you are going to use one or both WAN ports For one WAN port you may need a fully qualified domain name either for convenience or if you have a dynamic IP address If you are going to use both WAN ports determine whether you are going to use them in fail over mode for increased network reliability or load balancing mode for maximum bandwidth efficiency See Chapter 2 Router Applications for more information 2 Set up your accounts Have access to the Internet and locate the Internet Service Provider ISP configuration information Each BiGuard 50G WAN port must be configured separately whether you are using a separate ISP for each WAN port or are having the traffic of both WAN ports routed through the same ISP 3 Determine your network management approach BiGuard 50G is capable of remote management However this feature is not active by default If you reset the device remote administration must be enabled again If you decide to manage your network remotely be sure to change the default 35 password for security reason 4 Prepare to physically connect BiGuard 50G to Cable or DSL modems and a computer Be sure to also review the Safety Warnings loca
