This Concept Map, created with IHMC CmapTools, has information related to: chp9, addressing scheme Three types of address forms Dynamic:which provides a mechanism that automatically assigns a physical address to a station when the station first boots., addressing scheme Three types of address forms Configurable: which provides a mechanism that a customer can use to set a physical address., each frame transmitted across a shared LAN includes two address-one that specifies the intended recipient and another that specifies the sender. Two ways to check the content of the frames? Implicit frame type:the network hardware does not include a type field in each frame. Instead,the frame carriers only data., Hardware addressing and Frame type Identification network communication Multicasting, Broadcasting which refers to transmissions that are available to a large audience., Each LAN technology defines a frame format. Most technologies have frames that each consist of a header followed by a data area. Because the size and format of the header is fixed, all frames used with a given technology have the same header format. The size of the data area is determined by the data being sent in the frame. however Some technologies do not include a type field in the frame header.How??, Hardware addressing and Frame type Identification What is this chapter about? Introduction: this chapter will explains how network interface hardware uses such address to filter incoming packets., addressing scheme Three types of address forms Static:which relies on the hardware manufacturer to assign a unique physical address to each network interface., each frame transmitted across a shared LAN includes two address-one that specifies the intended recipient and another that specifies the sender. more on frames Each LAN technology defines a frame format. Most technologies have frames that each consist of a header followed by a data area. Because the size and format of the header is fixed, all frames used with a given technology have the same header format. The size of the data area is determined by the data being sent in the frame., Hardware addressing and Frame type Identification network communication Broadcasting, addressing scheme in which each attached station is assigned a physical address,hardware address, or MAC address, which is checked by hardware to determine acceptance., Multicasting which is like broadcasting, but when the copies are received the network interface does not automatically forward multicast frames to the CPU., each attached station is assigned a physical address,hardware address, or MAC address, which is checked by hardware to determine acceptance. furthermore each frame transmitted across a shared LAN includes two address-one that specifies the intended recipient and another that specifies the sender., each frame transmitted across a shared LAN includes two address-one that specifies the intended recipient and another that specifies the sender. Two ways to check the content of the frames? Explicit frame type:here the network hardware designers specify how type information is included in the frame and the values used to identify various frame types., Physically, any signal sent across a shared network reaches all attached stations. How can two computers communicate directly? addressing scheme, Some technologies do not include a type field in the frame header.How?? two possible ways Before any data is sent, the sender and reciever agree to use a single format for data. Software in the sending computeris programmed to place outgoing data in the chosen format, and software in the receiving computer is programmed to expect data in the chosen format., Some technologies do not include a type field in the frame header.How?? two possible ways Before any data is sent , the sender and reciever agree to use the first few octets of the data field to store type information. Software on the sending computer adds type information to the beginning of the data before placing the data in an outgoing frame. Software in the recieving computer extracts the type information and uses the type to determine how to process the remainder of the data., Hardware addressing and Frame type Identification in general Physically, any signal sent across a shared network reaches all attached stations.
