48 public class MapRegister {
50 * P: This is the proxy Map-Reply bit. When set to 1, an ETR sends a
51 * Map-Register message requesting the Map-Server to proxy a Map-Reply. The
52 * Map-Server will send non-authoritative Map-Replies on behalf of the ETR.
53 * Details on this usage can be found in [RFC6833].
55 private boolean proxyMapReply;
57 * M: This is the want-map-notify bit. When set to 1, an ETR is requesting a
58 * Map-Notify message to be returned in response to sending a Map-Register
59 * message. The Map-Notify message sent by a Map-Server is used to
60 * acknowledge receipt of a Map-Register message.

65 * Nonce: This 8-octet 'Nonce' field is set to 0 in Map-Register messages.
66 * Since the Map-Register message is authenticated, the 'Nonce' field is not
67 * currently used for any security function but may be in the future as part
68 * of an anti-replay solution.
73 * Key ID: This is a configured ID to find the configured Message
74 * Authentication Code (MAC) algorithm and key value used for the
75 * authentication function. See Section 14.4 for codepoint assignments.
80 * Authentication Data Length: This is the length in octets of the
81 * 'Authentication Data' field that follows this field. The length of the
82 * 'Authentication Data' field is dependent on the MAC algorithm used. The
83 * length field allows a device that doesn't know the MAC algorithm to
84 * correctly parse the packet. private short authenticationLength;
88 * Authentication Data: This is the message digest used from the output of
89 * the MAC algorithm. The entire Map-Register payload is authenticated with
90 * this field preset to 0. After the MAC is computed, it is placed in this
91 * field. Implementations of this specification MUST include support for
92 * HMAC-SHA-1-96 [RFC2404], and support for HMAC-SHA-256-128 [RFC4868] is

100 * above and occurs the number of times equal to Record Count.
