Abstract
A network element employing multiple namespaces in performing IP packet routing. The network element maintaining two or more namespaces. A first namespace corresponds to an in-band network domain and a second namespace corresponds to an out-of-band network domain. The network element performing IP packet routing over the in-band network domain and the out-of-band network domain using said two or more namespaces. Embodiments allow operators to more easily implement separate routing tables for “in-band” and “out-of-band” communication. Having separate routing tables for in-band and out-of-band communication prevents malicious CPEs and hacked CMs from directly communicating to servers on the out-of-band network, thereby increasing security for CMTS operators.
