Monocyte chemotactic protein 1. ATM cell packet size or cell size is 53 octets(bytes). □ Uses virtual circuits for moving data. 2 µm is generally recommended. Each cell consists of 53 octets, or bytes. That is, ATM networks transmit their information in small, fixed length packets called “cell” each of which contains 48-octets (or bytes) of data and 5-octets of header information. Because the cells are fixed in length (53 octets, or bytes) rather than variable such as an Ethernet frame, they can be switched in ATM: What it is, and what it isn't. ATM uses a connection-oriented model in which a virtual circuit must be established between two endpoints before the actual data exchange begins. • Fixed size cells 53 bytes. VPIs for a particular virtual channel connection are discovered during the connection setup process for switched virtual circuit (SVC) connections and manually configured for permanent virtual circuit (PVC) connections. The small, fixed cell size was chosen to facilitate the rapid processing Asynchronous transmission allows cells to be positioned anywhere within the data stream. ,Limitations,Why ATM is used??,Why cell size is 53 Bytes,ATM Protocol Architecture,ATM Applications. 2.
