Peng Zhang, in Advanced Industrial Control Technology, 2010 (2) The data-link layer The fieldbus data-link layer protocol is a hybrid, capable of supporting both scheduled and asynchronous transfers.Its maximum packet size is 255 bytes, and it defines three types of data-link layer entities: a link master, a basic device, and a bridge. This TCP package is received by the internet layer which wraps some IP protocol headers with source and destination IP addresses. Snoop-TCP One of the main feature of I-TCP also goes on to become its major disadvantage i.e. The fact that the Internet functions today at a far bigger scale than its founders anticipated is a testament to their work. 39. Layer 2, also known as the Data Link Layer, is the second level in the seven-layer OSI reference model for network protocol design. A good place for the enhancement of TCP could be the foreign agent in the Advantages of Indirect TCP includes. TCP/IP: The security of TCP/IP sockets in Windows 2000 and Windows XP (but not in Vista) is effectively null.
