Hybrid security architecture (HSA) provides a platform for middlebox traversal in the network. The HSA decouples the middlebox control from network forwarding. More specifically, such embodiments may receive a data packet having a packet header including an Ethernet header identifying source and destination addresses in the network. A traffic type of the data packet is determined. Then, layer-2 forwarding information, which encodes a set of non-forwarding network service provider middleboxes in the network to be traversed by the data packet, is determined based on the traffic type. The layer-2 forwarding information is inserted into the Ethernet header and the data packet is forwarded into the network. The data packet will then traverse, according to the layer-2 forwarding information, a sequence of the middleboxes in the network, wherein at least one non-forwarding network service will be provided by each of the middleboxes to the data packet in a sequence.

The monitoring data packets are transmitted and the performance data are generated from the monitoring data contained in the monitoring data packets.

For transmitting data between a base station and a transponder, information packets modulated onto an electromagnetic carrier wave each include a header section, a middle section, and an end section. The data are encoded in the middle section using information symbols, e.g. representing digital "1s" and "0s". The header section of at least the first packet defines the number and unique identifications of all of the symbols that will be used for encoding the data in the middle section of this and / or subsequent packets. This transmission protocol defined in the header section can be varied in subsequent packets to adaptively adjust the transmission rate depending on the existing communication conditions and requirements such as high frequency regulations prescribed by national law. The transmission rate can be considerably increased, in comparison to a transmission rate that would otherwise be necessary for achieving a reliable transmission even under unfavorable conditions.

Compression of message headers. A message including an uncompressed header, a message including a compressed header or a request to support header compression is received. In response, a determination of the impact of header compression on performance is determined. If the determination is favorable, then header compression is supported for subsequent communications. However, if the determination is not favorable, then header compression is not supported for subsequent communications. If the impact of header compression on performance is determined to be favorable, then an identifier for a reference header is returned. The identifier is for use in a subsequent compressed header. The subsequent compressed header comprises the identifier and changes relative to the reference header. A server receives a message including a compressed header. The server determines whether it has sufficient memory or storage to support header compression. If so, the server handles the message, but if not, the server refuses to handle the message or notifies a sender of the message that it will not support header compression for subsequent messages.
