Networking with tcp ip Proficiency.pptx

  1. 1. Networking with TCP/IP Subject Code: 150512 ASSESSMENT OF PROFICIENCY IN COURSE Submitted to: Prof. Sapna Kushwah Submitted By: Tanay Manavat 0901CS201129
  2. 2. UNIT-1  Address Resolution Protocol (ARP) is a communication protocol that works on the TCP/IP Layer 2.  ARP helps to get the MAC address of the connected router or gateway from the IP address.  ARP is a request-response protocol in which one device sends a request to another device asking for some information, and the other device will respond/reply with the required information.  ARP packets are encapsulated by a link layer and are distributed only in a specific network. ARP is said to be a link-layer protocol.
  3. 3. UNIT-2  RARP protocol is used by a device that knows its MAC address but does not know its IP address in a local area network (LAN).  A network administrator creates a table in a local area network (LAN) gateway router that maps the physical machine addresses to equivalent IP addresses.  When a new machine is set up, then its RARP client requests the IP address from the gateway router.  Assuming that an entry has been set up in the router table, the reserve ARP server will return the IP address to the machine which can store it for future use.  The problem of getting an IP address from a MAC address can be handled by the reserved address resolution protocol (RARP) which works similarly to ARP.
  4. 4. UNIT-3  Inverse ARP is the opposite of ARP. Instead of using a layer-3 IP address to find a layer- 2 MAC address, Inverse ARP uses layer-2 MAC addresses to find a layer-3 IP address.  Inverse ARP is mostly used by Frame relay and ATM Networks to map the DLCI to IP Address. So the router asks for the IP Address of the destination or other ends of PVC by listing DLCI for that router.
