Four Workgroups with four desktops in each workgroup. Theory: Hubs and Switches are two important connecting devices in computer networks. Hubs: A hub is a multiport repeater.
It is normally used to create connections between stations in a physical star topology. It is used widely in Ethernet implementations. They can also be used to create multiple levels of hierarchy. It forwards every frame and has no filtering capability. Switches: A two layered switch is a bridge with many ports that can allocate a unique port to each station.
This means no competing traffic. It makes a filtering decision based on the MAC address of the frame it received. More sophisticated switches have buffer to hold the frames of processing. Select end system as desktop and drag and drop the required number of systems. Connect four desktops to a hub. Connect all the four hubs to a switch to complete the network. Network should be wireless and all computers should belong to same workgroup say 1 should have dynamic IP address.
Procedure: Drag and drop required number of PCs on screen. A Workgroup with four desktops and four wireless PCs. Perform Static and Dynamic Routing. With static routing, you maintain the routing table manually using the route command. Static routing is practical for a single network communicating with one or two other networks. However, as your network begins to communicate with more networks, the number of gateways increases, and so does the amount of time and effort required to maintain the routing table manually.
With dynamic routing, daemons update the routing table automatically. Routing daemons continuously receive information broadcast by other routing daemons, and so continuously update the routing table. The routed daemon only supports Routing Information Protocol. Routing daemons can operate in one of two modes, passive or active, depending upon the options you use when starting the daemons. In active mode, routing daemons both broadcast routing information periodically about their local network to gateways and hosts, and receive routing information from hosts and gateways.
In passive mode, routing daemons receive routing information from hosts and gateways, but do not attempt to keep remote gateways updated they do not advertise their own routing information. These two types of routing can be used not only for gateways, but for other hosts on a network as well. Static routing works the same for gateways as for other hosts. Dynamic routing daemons, however, must be run in the passive quiet mode when run on a host that is not a gateway. Drag and drop required number of PCs on screen.
This is equivalent to 2 public IP addresses. Since the company has an internal requirement for more than 2 addresses, the IT manager has decided to implement NAT with overload.Sc Lecture Notes M.BASIC INTRODUCTION of CCN LAB USING ns2 -- VTU -- 6 th sem --ECE

It breaks the datagrams passed down by above layers and converts them into frames ready for transfer. This is called Framing. It provides two main functionalities Reliable data transfer service between two peer network layers Flow Control mechanism which regulates the flow of frames such that data congestion is not there at slow receivers due to fast senders. What is framing? Since the physical layer merely accepts and transmits a stream of bits without any regard to meaning or structure, it is up to the data link layer to create and recognize frame boundaries.
This can be accomplished by attaching special bit patterns to the beginning and end of the frame. If these bit patterns can accidentally occur in data, special care must be taken to make sure these patterns are not incorrectly interpreted as frame delimiters.
The four framing methods that are widely used are 1. Character count 2. Starting and ending characters, with character stuffing 3. Starting and ending flags, with bit stuffing 4. Physical layer coding violations 1.
Character Count This method uses a field in the header to specify the number of characters in the frame.
When the data link layer at the destination sees the character count, it knows how many characters follow, and hence where the end of the frame is. The disadvantage is that if the count is garbled by a transmission error, the destination will lose synchronization and will be unable to locate the start of the next frame.
So, this method is rarely used. This method overcomes the drawbacks of the character count method. Since this can interfere with the framing, a technique called character stuffing is used. Disadvantage: character is the smallest unit that can be operated on; not all architectures are byte oriented and this is a major hurdle in transmitting arbitrary sized characters.Add To My Wish List.

Once fully implemented, CCN will be the preferred national network VA uses to purchase care for Veterans in their community. CCN uses industry-standard approaches and guidelines to administer services, promptly pay for services and manage the network to its full potential.
CCN is comprised of six regional networks that serve as the contract vehicle for VA to purchase care for Veterans from community providers. Optumpart of UnitedHealth Group, Inc. CCN is comprised of six regional networks.
It covers all U. CCN has an established set of regional boundaries aligned to state boundaries to provide local flexibility and increased access to care. With CCN, there is a focus on transparency, accountability, quality, and increased communications between VA and Veterans. CCN is a robust network of community providers that provides Veterans greater choice and accessibility to care outside of VA medical facilities.
The CCN contracts were developed with a focus on transparency, accountability, quality and increased communications between VA and Veterans. Veterans can also schedule their own appointments with support from local VA medical facility staff, if desired. Health care services provided as part of CCN include medical, surgical, complementary and integrative health services CIHSand dental services for Veterans who are unable to receive care at a local VA medical facility.
Durable medical equipment DME and prescription medications up to a day supply will be provided for immediate needs. CCN expands coverage for additional services to include dialysis, comprehensive rehabilitation, residential care, home-health care, hospice care, dental, immunizations, and long-term acute care.
If a provider determines a prescription is immediately required, medications can be prescribed — up to a day supply — and filled at a participating in-network pharmacy for Veterans who were referred care through a CCN provider with an approved referral.
Veterans must provide prescription benefit information to a participating CCN pharmacy. If Veterans do not have an authorization for care through the CCN contractor or utilize a non-CCN participating pharmacy, they will have to pay out of pocket and seek reimbursement through their local VAMC. For prescriptions of more than a day supply, or if the prescribed medication is not immediately needed, then the community provider should send the prescription to the local VAMC pharmacy for fulfillment.
Under CCN, community providers must submit a referral request to VA when a Veteran requires care beyond what is included on the original referral. Before a Veteran receives care or services from a CCN participating provider, VA must refer the Veteran to a specific community provider. Veterans can verify the status of their referral through the Optum portal if they are in Regions 1, 2 or 3, and the TriWest portal if they are in Region 4.Learn more about Scribd Membership Home.

The interface consists of over different function calls which can be used to draw complex three-dimensional scenes from simple primitives.
SGI in and is widely used in CAD, virtual reality, scientific visualization, information visualization, and flight simulation. OpenGL's basic operation is to accept primitives such as points, lines and polygons, and convert them into pixels.
This is done by a graphics pipeline known as the OpenGL state machine. GLUT Fuctions A pointer to the program's unmodified argc variable from main. Upon return, the value pointed to by argcp will be updated, because glutInit extracts any command line options intended for the GLUT library.
The program's unmodified argv variable from main. Like argcp, the data for argv will be updated because glutInit extracts any command line options understood by the GLUT library. Height:- Height in pixels. Y :- Window Y location in pixels. Syntax:- void glutInitDisplayMode unsigned int mode.
