System and method for routing data over an internet protocol security network

A system for routing data over an Internet Protocol security network, the system comprising:

• a traffic management module to control the order of processing of packets;
• a sequence number allocator to allocate sequence numbers to packets in the order of processing of packets in the traffic management module and feeding the packets to a post-queue line interface module;
• a post-queue line interface module to provide packets with the appropriate security features;
• and
• a transmitter to transmit packets over the Internet Protocol security network.

A machine-readable medium comprising instructions, which when executed by a machine, cause the machine to:

• receive packets for transmission over an Internet Protocol security network;
• control an order of processing of the packets;
• determine whether each packet requires security features;
• feed the packets to a post-queue line interface module according to the order of processing of the packets;
• allocate, in response to the determination that a packet requires security features, a sequence number to each packet in the order of feeding of packets to the post-queue line interface module;
• provide said packet with appropriate security features;
• and
• transmit said packet over the Internet Protocol security network.

A system for routing data over an Internet Protocol security network, the system comprising:

• means for controlling the order of processing of packets;
• means for allocating sequence numbers to packets in the order of processing of packets in the traffic management module and for feeding the packets to the post-queue line interface module;
• means for providing packets with the appropriate security features;
• and
• means for transmitting packets over the Internet Protocol security network.
