ALSO CALLED: HSTR, 16Mb Token, 4Mb Token, 16 Mbps Token Ring Protocols, 4 Mbps Token Ring Protocols, Token Ring, High Speed Token Ring
DEFINITION: A Token Ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time. The Token Ring protocol is the second most widely-used protocol on local area networks after Ethernet. The IBM Token Ring protocol led  …

Securing Layer 2
sponsored by Global Knowledge
WHITE PAPER: For many years network administrators have expected security breaches to come from outside an organization or at the upper layers of the OSI model. This paper will focus on securing layer 2 switching at the access layer through port security and preventing denial of service (DoS) attacks at layer 2.

TOKEN RING PROTOCOLS DEFINITION (continued): …  to a standard version, specified as IEEE 802.5. Both protocols are used and are very similar. The IEEE 802.5 Token Ring technology provides for data transfer rates of either 4 or 16 megabits per second. Very briefly, here is how it works:Empty information frames are continuously circulated on the ring.When a computer has a message to send, it inserts a token in an empty frame (this may consist of simply changing a 0 to a 1 in the token bit part of the frame) and inserts a message and a destination identifier in the frame.The frame is then examined by each successive workstation. If the workstation …
