Systems and methods for managing network traffic receives, at a grade of service device, network traffic information for a plurality of network traffic channels from a network device separate from the grade of service device. The network traffic information is compared to a threshold to determine a behavior value for each network traffic channel. Each network traffic channel is mapped to a grade of service according to the behavior value.

A receiving device including a receiver and circuitry is provided. The receiver is configured to receive a digital broadcast signal transmitted using an Internet Protocol (IP) transmission method. The digital broadcast signal includes Layered Coding Transport (LCT) packets. The circuitry is configured to extract one of the LCT packets based on filtering information arranged in a header of the one of the LCT packets transmitted in a first layer that is higher than an IP layer of a protocol of the IP transmission method in the digital broadcast signal, and process first signaling data contained in the one of the LCT packets. The LCT packets are transmitted using a session of the first layer. The filtering information includes compression information indicating compression/no-compression of the first signaling data, and type information indicating a type of the first signaling data.

Data migrations are not able to be identified or traced through a switched network to their originating hub, because the corresponding TCP/IP data stream goes through a plurality of optimized differential switches and the originating IP in the packet header gets replaced at each switch. The present invention provides a mechanism to introduce a lag or a jitter into the IP to label the migrated data. The labeled data are able to be traced and identified through multiple managed hubs and/or switches.
