EFFECT OF DYNAMIC ACL (ACCESS CONTROL LIST) LOADING ON PERFORMANCE OF CISCO ROUTERS

An ACL (access control list) is one of a few tools that network administrators often use to restrict access to various network objects. ACLs can also be used to control forwarding of traffic, facilitating so-called “policy based routing”. There is a current need to update ACLs dynamically by programmable tools with as low latency as possible. At Fermilab we have approximately four years of experience in the area of dynamic reconfiguration of network infrastructure. However, dynamic updates also introduce significant challenges for performance of networking devices. This paper introduces the results of our research, as well as practical experience in dynamic configuration of network infrastructure by using variou
