Key, and Zero-Padding Length. The Server ID is unique to each server, but the
others MUST be global.

Note that server IDs are opaque bytes, not integers, so there is no notion of
network order or host order.

A full QUIC-LB configuration MUST also specify the information content of the
first CID octet and the presence and mode of any Retry Service.

# Load Balancer Test Vectors {#test-vectors}

Because any connection ID encoding in this specification includes many bits
for server use without affecting extraction of the server ID, there are many
possible connection IDs for any given set of parameters. However, every
connection ID should result in a unique server ID. The following connection
IDs can be used to verify that a load balancer implementation extracts the
correct server ID.
Each section of this draft includes multiple sets of load balancer
configuration, each of which has five examples of server ID and server use
bytes and how they are encoded in a CID.

In some cases, there are no server use bytes. Note that, for simplicity, the
first octet bits used for neither config rotation nor length self-encoding are
random, rather than listed in the server use field. Therefore, a server
implementation using these parameters may generate CIDs with a slightly different
first octet.

This section uses the following abbreviations:

cid Connection ID
cr_bits Config Rotation Bits
LB Load Balancer
sid Server ID
sid_len Server ID length
su Server Use Bytes

All values except length_self_encoding and sid_len are expressed in hexidecimal
format.
