  • As network operators add new capacity, technologies and equipment to their networks, they often find themselves with older network elements that no longer meet their needs. Additionally, as some operators grow through acquisition, they sometimes find themselves with duplicated facilities that add unnecessary capital and operating expenditures. And other operators are faced with asset disaggregation or divestiture as the result of changing business models.

  • The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process.

  • Limit network traffic to increase network performance. For example, if corporate policy does not allow video traffic on the network, ACLs that block video traffic could be configured and applied. This would greatly reduce the network load and increase network performance. 2. Provide traffic flow control. ACLs can restrict the delivery of routing updates. If updates are not required because of network conditions, bandwidth is preserved. 3. Provide a basic level of security for network access.
