The acticom compression protocol stack software for IoT provides RFC6282 (6LoWPAN) compliant compression of IPv6 and UDP header information, plus RFC7400 defined Generic Header Compression (GHC) for IPv6 over Low-Power Wireless Personal Area Networks.

While RFC6282 allows for compression of IPv6 and UDP in IEEE 802.15.4 networks (6LoWPAN-HC). The GHC adds a more general, form of compression for headers of any kind and even for header-like payloads such as those exhibited by routing protocols, DHCP, etc.

Higher Efficiency

The number of Internet of Things (IoT) devices will significantly increase, which results in an increased demand for the use of IPv6 and the actual adoption of IPv6 for the device communication. IPv6 adds at least 20bytes to each IP datagram transmitted (compared to IPv4) by IoT devices carrying user data such as voice, control information, or sensor data. Small IoT devices and applications transfer small amounts of data, including voice data, for which a typical payload size equals just around 25 bytes per IPv6 datagram. Sensor data, control information, or status information is considered to be equally small.
Thus the ratio between payload (e.g. 20 byte) and IPv6 header size (40 byte) equals 1:2. This means for each 20 byte payload, the network carries 40 bytes of “address” information, the so called “overhead”.
This ratio becomes even worse if the higher layer protocols are taken into account as well: 20 byte payload vs. IPv6 + UDP plus RTP for voice data (60 byte) results in a ratio of 1:3.

Low Latency

Especially wireless links / networks are affected by low packet throughput, jitter, and delay; as a consequence, especially voice applications suffer from these shortcomings. Header compression is capable of reducing delay, allowing to process smaller packets faster; it allows to control the jitter, and it addresses the packet throughput by increasing the efficiency and reducing the error probability by reducing the packet size.

Reliability

The application of header compression reduces the size of a packet significantly. Wireless links are error prone as they are suffering from high error probability. While a bit error probability remains stable, header compression addresses the packet error probability. A shorter (smaller) packet has a lower error probability than a normal sized packet. In addition, the use of header compression in an IoT (or other wireless networks) increases the service security (reliability) by the fact that the important header information – the address and application information, which must remain intact at all times – is protected by reducing its size down to a minimum, actually resulting in a header error probability that is equal to the error probability of just 1 to 2 bytes on the wireless link.

Security

By compressing headers of IPv4 and IPv6 datagrams on a communications link using a context based compression, it becomes harder to eavesdrop on such link. Of course, header compression does not include any kind of encryption, thus the payload remains unchanged at all time. However, the pure reduction of the protocol header information down to e.g. a single byte prevents an eavesdropper from matching IP datagrams to a specific traffic stream without knowledge of the compression context and compression scheme. But as additional benefit, the encryption of a compressed header portion or a shorter packet needs less computational resources than the encryption of a full sized packet, respectively the full sized header. In turn, the saved CPU cycles could be used to apply even stronger encryption without needs for additional CPU power.

Availability: Now – acticom compression protocol stack software for IoT is available now.

Simple Licensing: acticom offers simple and straightforward licensing for its protocol software. A single license covering both versions, or just the chosen version. The software, support, and deliverable options are equal. The license grants all necessary rights to integrate the software, modify and port as required, and distribute with the chosen products. Source code can be included, along with initial integration support, and documentation.

Options to extend the software by additional compression profiles or specific modifications should not affect the license and granted flexibility to use the software, thus add-ons are always following the basic, simple acticom one time license model.
