...There are different tools available to help in the configuration and troubleshooting of networks. TRACERT and Ping are two of them. This assignment will be discussing troubleshooting procedures of both. These two tools of troubleshooting are among the most popular and can be used on Windows as well as other platforms. They are very simple to use and give out a lot of output but very little input. TRACERT decides the route by sending the first echo packet with a TTL of 1 and incrementing the TTL by 1 on each subsequent transmission until the target replies or the full TTL is reached. The TRACERT command determines where a packet stopped on the network. Default gateway found there was not a valid path for the host. Could possibly have a configuration problem with the router or network where several paths can be taken to arrive at the same place, or where several intermediate systems which can include a router or bride can be involved. Time Exceeded message is a command that is used by the TRACERT along with IP TTL field letting it be known that each router has a successive router in a route. A Port Unreachable message is a message that the traceroute command that the complete route has been found, and the command can quit. In conclusion of the TRACERT command, this tool is much better because it determines if the route works, and it can supply the IP address of each router in the route. Ping allows computers to talk between each other’s and this helps narrow down the cause of...

...Kelly Keys NT2640 Fri. Night Project Paper 1. Routing tables and how the router will perform a route lookup: a. Routing Table Format- A routing table is used by TCP/IP network routers to calculate the destinations of messages it is responsible for forwarding. The table is a small in-memory database managed by the router's built-in hardware and software. Each IP address identifies a remote router (or other network gateway) that the local router is configured to recognize. For each IP address, the routing table additionally stores a network mask and other data that specifies the destination IP address ranges that remote device will accept. Home network routers utilize a very small routing table because they simply forward all outbound traffic to the Internet Service Provider (ISP) gateway which takes care of all other routing steps. Home router tables typically contain ten or fewer entries. By comparison, the largest routers at the core of the Internet backbone must maintain the full Internet routing table that exceeds 100,000 entries and growing as the Internet expands. b. Routing Lookup Mechanism- c. Classful vs. Classless Routing- Classful Routing, which is sometimes called a classful network. If you are using a classful routing protocol then all of your networks are in different classes and are separated by a router. Remember that the useable IPv4 address ranges are divided into classes. Class A 1-126, Class B 128-191, and Class C 192-223. So when we talk about...

...DECEMBER 2007 Book Review Call for Papers Download PDF Fragments From the Editor IP Spoofing Looking Toward the Future Remembering Itojun Security Standards Layers above IP use the source address in an incoming packet to identify the sender. To communicate with the sender, the receiving station sends a reply by using the source address in the datagram. Because IP makes no effort to validate whether the source address in the packet generated by a node is actually the source address of the node, you can spoof the source address and the receiver will think the packet is coming from that spoofed address. Many programs for preparing spoofed IP datagrams are available for free on the Internet; for example, hping lets you prepare spoofed IP datagrams with just a oneline command, and you can send them to almost anybody in the world. You can spoof at various network layers; for example, you can use Address Resolution Protocol (ARP) spoofing to divert the traffic intended for one station to someone else. The Simple Mail Transfer Protocol (SMTP) is also a target for spoofing; because SMTP does not verify the sender's address, you can send any email to anybody pretending to be someone else. This article focuses on the various types of attacks that involve IP spoofing on networks, and the techniques and approaches that experts in the field suggest to contend with this problem. Spoofing IP datagrams is a wellknown problem that has been addressed in various research papers. Most spoofing is done f...

... The heart of IP is the IP datagram, a packet sent over the Internet in a connectionless manner. An IP datagram carries enough information about the network to get forwarded to its destination; it consists of a header followed by bytes of data . The header contains information about the type of IP datagram, how long the datagram should stay on the network (or how many hops it should be forwarded to), special flags indicating any special purpose the datagram is supposed to serve, the destination and source addresses, and several other fields, as shown in Figure 1. Figure 1: The IP Header Layers above IP use the source address in an incoming packet to identify the sender. To communicate with the sender, the receiving station sends a reply by using the source address in the datagram.

Today, over 5.6 billion subscribed devices are in active use, which represent approximately 80% of the world population and are rising. (Gartner) Improved reception power coupled with increased network coverage and penetration, global roaming capability, sharp quality, fitto-palm size with large screen and lightweight are the significants of today’s user terminals. Given such advances, the growth within the large increases of cellular use has been on mobile data. In 2011, the total mobile data service revenues were close to $315 billion (Gartner). LTE is a serious improvement in network architecture to handle this surge in demand and is embraced by all providers. This paper first describes the background of LTE and then outlines the important challenges. Two of the challenges are related to the handover technologies and techniques on providing the required QoS for services, they are discussed in finer details. 1.

...traffic between networks or hosts that employ differing security postures. While firewalls are often discussed in the context of Internet connectivity, they may also have applicability in other network environments. For example, many enterprise networks employ firewalls to restrict connectivity to and from the internal networks used to service more sensitive functions, such as accounting or personnel. By employing firewalls to control connectivity to these areas, an organization can prevent unauthorized access to its systems and resources. Inclusion of a proper firewall provides an additional layer of security (Broida, 2011). This research paper will give a background on firewalls. The background will cover an overview of firewall technologies, as well as firewall technologies, the common requirements of firewalls, and firewall policies. This paper will also give an analysis of firewalls which will consist of what I have learned in doing this research and my opinion on the research. Overview of Firewall Technologies Several types of firewall technologies are available. One way of comparing their capabilities is to look at the Transmission Control Protocol/Internet Protocol [TCP/IP] layers that each is able to examine. TCP/IP communications are composed of four layers that work together to transfer data between hosts. When a user wants to transfer data across networks, the data is passed from the highest layer through intermediate layers to the lowest layer, with each layer adding...
