Satellite links are widely used for long-distance communication, especially in areas where terrestrial networks are unavailable or unreliable. The latest version of the Internet Protocol (IP), IPv6, can be used over satellite links to provide a large address space and advanced features for routing and addressing.
In this blog post, we will discuss the basics of IPv6 over satellite links, including the frame format and addressing used in this combination of technologies.
IPv6 over satellite links refers to the use of IPv6 on satellite links, such as those used for satellite phones, satellite television, and satellite internet. IPv6 can be used in the same way as IPv4 over satellite links, but there are some differences in the frame format and addressing used in IPv6 over satellite links.
A satellite frame is the basic unit of data transmission in a satellite link. It consists of a header and a payload, as well as some other fields that are used for error detection and correction.
The header of a satellite frame includes several fields that are used to identify the source and destination of the frame. These fields include:
IPv6 addresses are a fundamental component of IPv6 over satellite links, as they are used to identify devices and route packets across the network.
IPv6 addresses used in satellite links can be of two types: link-local addresses and global addresses.
Link-local addresses are used for communication within a single satellite link, similar to link-local addresses used in Ethernet or Wi-Fi. They are automatically assigned to an interface when it is initialized and are only valid within the local network segment.
Link-local addresses are identified by the prefix fe80::/10 and the interface identifier that is derived from the device's MAC address or another unique identifier.
Global addresses are used for communication across different satellite links or over the Internet. They are assigned by Internet Service Providers (ISPs) or other organizations and are globally unique.
Global addresses are identified by a prefix that identifies the network and a 64-bit interface identifier that is typically derived from the device's MAC address or another unique identifier.
IPv6 over satellite links is becoming increasingly important as more communication occurs between satellite devices and the rest of the internet. IPv6 provides a large address space and advanced features for routing and addressing, while satellite links provide a flexible way to connect to the internet, especially in remote areas.
In this blog post, we discussed the basics of IPv6 over satellite links, including the frame format and addressing used in this combination of technologies. We explained how satellite frames are structured and how IPv6 addresses are assigned and used for communication within and between satellite links.
By understanding the basics of IPv6 over satellite links, network administrators can ensure that their networks are configured correctly and are capable of efficiently forwarding data across different satellite links and the internet.
