Delayed Binding

Delayed Binding

Delayed binding, also called TCP splicing, is the postponement of the connection between the client and the server in order to obtain sufficient information to make a routing decision. Some application switches and routers delay binding the client session to the server until the proper handshakes are complete so as to prevent Denial of Service attacks.

IP Filtering

ADNs often have the ability to filter traffic based on Access Control Lists (ACLs), Bogus IP ranges (Bogon filtering) and deep patcket inspection pattern matching. In some cases, thresholds or rate limiting of IP addresses or ranges of IP addresses may be employed.

Traffic Management

ADNs are increasingly adding advanced traffic management funtionality. The deep packet inspection capabilities of some of these products can identify identify traffic by application type and can be used to analyze, block, shape and prioritize traffic.
