A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
sequence number for this data or control message, beginning at zero and incrementing by one (modulo 2 16) for each message sent. Present only when sequence flag set. Nr (optional) sequence number for expected message to be received. Nr is set to the Ns of the last in-order message received plus one (modulo 2 16). In data messages, Nr is ...
Logical View of a Layer 2 MPLS VPN. A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses. Layer 2 VPNs are a type of Virtual Private Network (VPN ...
WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]
Optional. Padding for encryption, to extend the payload data to a size that fits the encryption's cipher block size, and to align the next field. Pad Length: 8 bits Size of the padding (in octets). Next Header: 8 bits Indicates the protocol type of the Payload Data, [27]: §2.6 like the value 6 for TCP.

These formats provide a consistent framework for transferring key and authentication data which is independent of the key generation technique, encryption algorithm and authentication mechanism. ISAKMP is distinct from key exchange protocols in order to cleanly separate the details of security association management (and key management) from ...
Microsoft Point-to-Point Encryption (MPPE) encrypts data in Point-to-Point Protocol (PPP)-based dial-up connections or Point-to-Point Tunneling Protocol (PPTP) virtual private network (VPN) connections. 128-bit key (strong), 56-bit key, and 40-bit key (standard) MPPE encryption schemes are supported.
