Cyclic Redundancy Check
A cyclic redundancy check (CRC) is a type of function that takes as input a data stream of unlimited
length and produces as output a value of a certain fixed size. The term CRC is often used to denote
either the function or the function's output. A CRC can be used in the same way as a checksum to
detect accidental alteration of data during transmission or storage. CRCs are popular because they are
simple to implement in binary hardware, are easy to analyze mathematically, and are particularly good
at detecting common errors caused by noise in transmission channels. From Wiki

IP Encapsulating Security Payload — An IPsec header providing encryption and authentication
capabilities defined in RFC 4303. The Encapsulating Security Payload (ESP) extension header provides
origin authenticity, integrity, and confidentiality protection of a packet. ESP also supports encryption
only and authentication-only configurations, but using encryption without authentication is strongly
discouraged. Unlike the AH header, the IP packet header is not accounted for. ESP operates directly on
top of IP, using IP protocol number 50. ESP fields:
• Security Parameters Index (SPI): See AH
• Sequence Number: See AH
• Payload Data: See AH
• Padding: Used with some block ciphers to pad the data to the full length of a block.
• Pad Length: Size of padding in bytes.
• Next Header: Identifies the protocol of the transferred data.
• Authentication Data: Contains the data used to authenticate the packet.

Hyper Thread Intel's trademark for implementation of the simultaneous multithreading technology on
the Pentium 4 microarchitecture. It is a more advanced form of Super-threading that debuted on the
Intel Xeon processors and was later added to Pentium 4 processors. The technology improves
processor performance under certain workloads by providing useful work for execution units that
would otherwise be idle, for example during a cache miss. A Pentium 4 with Hyper-Threading enabled
is treated by the operating system as two processors instead of one. From Wiki

IP tunneling
|
IP tunneling is the process of embedding one IP packet inside of another, for the purpose of simulating
a physical connection between two remote networks across an intermediate network.
IP tunnels are often used in conjunction with IPSec protocol to create a VPN between two or more
remote networks across a "hostile" network such as the Internet.

| ip sec |
IP security) is a suite of protocols for securing Internet Protocol (IP) communications by authenticating
and/or encrypting each IP packet in a data stream. IPsec also includes protocols for cryptographic key
establishment.
IPsec is implemented by a set of cryptographic protocols for (1) securing packet flows and (2) internet
key exchange. There are two families of key exchange protocols.
The IP security architecture uses the concept of a security association as the basis for building security
functions into IP. A security association is simply the bundle of algorithms and parameters (such as
keys) that is being used to encrypt a particular flow. The actual choice of algorithm is left up to the
users. A security parameter index (SPI) is provided along with the destination address to allow the
security association for a packet to be looked up.
For multicast, therefore, a security association is provided for the group, and is duplicated across all
authorized receivers of the group. There may be more than one security association for a group, using
different SPIs, thereby allowing multiple levels and sets of security within a group. Indeed, each
sender can have multiple security associations, allowing authentication, since a receiver can only know
that someone knowing the keys sent the data. Note that the standard doesn't describe how the
association is chosen and duplicated across the group; it is assumed that a responsible party will make
the choice. From Wiki

LinkSec (or MACsec,
802.1AE)

cryptography. The 802.1AE defines an AES-GCM 128 bit key as a mandatory cipher suite which can be
processed by the LAN controller.

|
|
LLC header
|
802.2 defines a special header that includes a SNAP (subnetwork access protocol) header. Some
protocols, particularly those designed for the OSI networking stack, operate directly on top of 802.2
LLC, which provides both datagram and connection-oriented network services. This 802.2 header is
currently embedded in modern 802.3 frames (Ethernet II frames, aka. DIX frames).
The LLC header includes two additional eight-bit address fields, called service access points or SAPs in
OSI terminology; when both source and destination SAP are set to the value 0xAA, the SNAP service is
requested. The SNAP header allows EtherType values to be used with all IEEE 802 protocols, as well as
supporting private protocol ID spaces. In IEEE 802.3x-1997, the IEEE Ethernet standard was changed
to explicitly allow the use of the 16-bit field after the Ethernet MAC Addresses to be used as a length
field or a type field. This definition is from Wiki

Next Generation VMDq
|
SW switch acceleration mode–central management of the networking resources by an IOVM or by the
VMM.
Virtual Machine Devices queue (VMDq) is a mechanism to share I/O resources among several
consumers. For example, in a virtual system, multiple OSs are loaded and each executes as though
the whole system’s resources were at its disposal. However, for the limited number of I/O devices, this
presents a problem because each OS may be in a separate memory domain and all the data movement
and device management has to be done by a VMM (Virtual Machine Monitor). VMM access adds
latency and delay to I/O accesses and degrades I/O performance. VMDs (Virtual Machine Devices) are
designed to reduce the burden of VMM by making certain functions of an I/O device shared and thus
can be accessed directly from each guest OS or Virtual Machine (VM).

精確時間協議（PTP）是一種用於在整個計算機網絡中同步時鍾的協議。在局域網上，它可實現亞微秒級的時鍾精度，使其適用於測量和控制系統。 IEEE 1588標准描述了用於時鍾分配的分層主從體系結構。在這種體系結構下，時間分配系統由一個或多個通信媒體（網段）和一個或多個時鍾組成。普通時鍾是具有單個網絡連接的設備，並且是同步基准源（PTP-master）或目標（PTP-slave）。邊界時鍾具有多個網絡連接，可以准確將一個網段與另一個網段同步。為系統中的每個網段選擇一個同步PTP-master。根定時基准稱為grandmaster。它將同步信息傳輸到在其網段上的時鍾。存在於該網段上的邊界時鍾隨后將准確的時間中繼到它們也連接到的其他網段 PTP消息使用基於Internet協議的用戶數據報協議（UDP / IP）進行傳輸。 IEEE 1588-2002第1版僅使用IPv4傳輸，但已將其擴展為在IEEE1588-2008規范中包括IPv6。在PTPv1 IEEE1588-2002中，所有PTP消息均使用多播消息傳遞發送，而PTPv2 IEEE1588-2008則為設備提供了選項在逐個端口的基礎上協商單播傳輸。組播傳輸使用IP組播編址，為IPv4和IPv6定義了組播組地址。 |

In cryptography, a salt consists of random bits used as one of the inputs to a key derivation function.
Sometimes the initialization vector, a previously generated (preferably random) value, is used as a
salt. The other input is usually a password or passphrase. The output of the key derivation function is
often stored as the encrypted version of the password. A salt value can also be used as a key for use in
a cipher or other cryptographic algorithm. A salt value is typically used in a hash function. from Wiki

|
The Security Parameter Index is an identification tag added to the header while using IPSec for
tunneling the IP traffic. This tag helps the kernel discern between two traffic streams where different
encryption rules and algorithms may be in use.
The SPI (as per RFC 2401) is an essential part of an IPSec SA (Security Association) because it enables
the receiving system to select the SA under which a received packet will be processed. An SPI has only
local significance, since is defined by the creator of the SA; an SPI is generally viewed as an opaque bit
string. However, the creator of an SA may interpret the bits in an SPI to facilitate local processing.
