2. Understanding Layer 2, 3, and 4 Protocols While many of the concepts well known to traditional Layer 2 and Layer 3 net- working still hold true in content switching applications, the area introduces new and more complex themes that need to be well understood for any success- ful implementation. Within the discussion of content networking, we will replace terms such as packets and frames with sessions and transactions as we move our attention further up the OSI Seven Layer Model. Before we move into these new terms, however, let's look at some standard Layer 2, 3, and 4 network- ing concepts. The OSI Seven Layer Model What Is a Layer ? Established in 1947, the International Organization for Standardization (ISO). was formed to bring together the standards bodies from countries around the world.
Ethernet, Token Ring, and Frame Relay are all examples of Data Link layer or Layer 2 protocols. Traditional Ethernet switches operate at the Data Link layer and are con-cerned with forwarding packets based on the Layer 2 addressing scheme. Layer 2 Ethernet switches are not concerned with whether the packet contains IP,
