Embodiment Construction

[0019] Certain terms are used throughout the description and claims to refer to particular components. It should be understood by those skilled in the art that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinguishing. The "comprising" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The invention provides a packet header deflation / expanding method and a related device. The packet header deflation method comprises receiving a data packet having a first length; abbreviating a header of the data packet to deflate the data packet into a deflated data packet having a second length shorter than the first length; and forwarding the shortened data packet. The packet header deflation / expanding method and the related device can save bandwidth and space in a packet buffer.

Description

【Technical field】 [0001] The present invention relates to computer networks, and more particularly to packet header deflation / inflation methods and related devices for network virtualization. 【Background technique】 [0002] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims recited in the claims and are not admitted to be prior art by inclusion in this section. [0003] In a streaming application, the overhead of Internet Protocol (IP), User Datagram Protocol (UDP) and Real-time Transport Protocol (RTP) is 40 bytes for IPv4 and 60 bytes for IPv6. For some applications, such as Voice over IP (VoIP), this overhead tends to take up approximately 60% of the total amount of data sent. Such a large overhead may be excessive for certain applications such as, for example, Wide Area Networks (WAN) and wireless systems where bandwidth is scarce. To alleviate the problem of large overhead, there are some methods of header compr...
