摘要： Various embodiments relate to a Cloud Data Center, a system comprising the Cloud Data Center, and a related method. The Cloud Data Center may include a logical customer edge router to send packets between addresses in a private enterprise network and addresses in a logical network within a cloud network using Layer 2 protocol and MAC addressing. The logical network may have resources, known as virtual machines, allocated to the private enterprise network and may share a common IP address space with the private enterprise network. A directory at the Cloud Data Center may correlate the enterprise IP addresses of virtual machines with a MAC address, cloud IP address, and a location IP address within the logical network. The Cloud Data Center may double encapsulate packets with MAC, cloudIP, and locIP headers, when sending a packet to a destination in the logical network.

摘要： To address the need for new techniques that are able to address overlapping channel collisions various embodiments are described. They are used to introduce the concept of retransmission-permutation, in which a bit-to-subcarrier assignment is permuted (1301) during packet retransmission (1302), thus departing from the well-known, simply-repeat paradigm. Various embodiments are straightforward to implement and able to exploit collision-free subcarriers to decode packets despite successive collisions in overlapping channels.
摘要翻译：为了解决能够解决重叠信道冲突的新技术的需要，描述了各种实施例。它们被用于引入重传置位的概念，其中在分组重传期间（1301）中的位到子载波分配被置换（1301），从而脱离了众所周知的简单重复的范例。各种实施例直接实现并且能够利用无冲突副载波来解码分组，尽管重叠信道中的连续冲突。
