The Axeda Wireless Protocol (AWP) is a messaging protocol for use between a wireless M2M device or agent and the Axeda Platform. AWP is a language, transport, and operating system independent application-layer protocol that you can use where an expressive messaging protocol is needed, while remaining compact and efficient over-the-wire. The protocol has been designed to take advantage of Axeda Platform functionality and to enable Axeda partners to produce integrated solutions using the Axeda Platform.
The Axeda Wireless Protocol (AWP) can be optimized to use as few bytes as possible to lower network costs. When multiple channels can be used (such as cellular networks, satellite, Internet, and WiFi), AWP supports Least-Cost Routing, where information is sent over a channel based on the information’s value and the channel’s cost. This enables you to control the application’s communication costs, while remaining flexible to business demands.
Key Features:
- Bidirectional data transfer, sending data to the Axeda Platform and information and files to an asset
- Well-documented technical references and toolkits
- Efficient design for optimized communication with use of bytes-over-the-wire
- Support for threshold rules programmed from the Axeda Platform and pushed down to assets
Key Benefits:
- Address wireless communication bandwidth constraints and reduce communication costs
- Remain open without relying on specific operating systems, programming languages, or communication transports
- Reduce processing and memory overhead with non-complex algorithms
Axeda Secure Messaging Protocol
To secure AWP, Axeda has developed the Axeda Secure Messaging Protocol (ASMP). Primarily intended for use in communications over wireless networks, ASMP is a compact protocol that minimizes bandwidth usage and does not assume any particular network transport mechanism. This protocol is perfect for use on resource-constrained devices.
The Axeda Secure Messaging Protocol (ASMP) provides the following security services:
- Message authentication - Enables protection of both the integrity and authenticity of the message. This prevents spoofing of the information transferred in the message and protects against “man-in-the-middle” attacks.
- Message confidentiality - Protects the privacy of the information in a message. Messages that are transmitted over public networks (even if public networks constitute only a part of the network path) often require this service. However, due to resource constraints, or availability of other mechanisms for data confidentiality (such as VPNs), the service may be seen as optional. Therefore, message confidentiality is optional in ASMP.
- Replay attack detection - Protects the recipient of a message against adversaries who intercept legitimately transmitted messages and retransmit them with malicious intent.
