ServiceGrid Article - Transport Layer Basic Overview
Cisco ServiceGrid provides a number of industry-standard transport protocols. Understanding the layer model of the Internet communication methods is important for a better understanding of different transport protocols.
The Internet Protocol Suite will be viewed as a set of layers like many protocol suites. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper-layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted.
The TCP/IP model consists of four layers. From lowest to highest, there are the Link Layer, the Internet Layer, the Transport Layer, and the Application Layer.
Internet and Link Layer
IP (Internet Protocol) is the basic layer. This protocol is used for communicating data across a packet-switched internetwork using the Internet Protocol Suite, also referred to as TCP (Transmission Control Protocol) or TCP/IP.
This is the layer providing methods to exchange data when using the SD bridge. Within the SD bridge, the following methods can be used to transport transactions from or to Cisco ServiceGrid:
- HTTPS Post
- HTTPS SOAP
For more information about transport methods and how to use them, refer to the SD.bridge transport layer.
