IPsec VPN data transmission processThe following is a packet transmission process (such as ICMP packet) through the IPsecVPN tunnel. When the PC in the subnet is protected by the VPN on the left, if the data sent from the left PC is received by the Left VPN eth1 port and nee

Recently, due to the high traffic of the primary data center, several independent hosts were purchased abroad for traffic distribution and cost. This requires two data centers.Data Synchronization, including MySQL, MongoDB, and reverse proxy. By creating a VPN using IPSec to connect two subnets togetherThe most suitable solution. We have initially considered usin

PHP data compression, encryption and decryption (pack, unpack), and data compression unpack Data is frequently exchanged in network communication and file storage. To reduce network communication traffic, file storage size, and encrypted communication rules, two-way encrypti

SQL Server focuses on optimization of Stored Procedure performance, data compression, and page compression to improve IO performance (I ). Preface The SQL Server basic series is not over yet, And the last point is not written, and will continue later. Some school friends asked me when I began to write the SQL Server performance series. It may take some time to wa

-EC routing protocol (RIP, OSPF, BGP, etc.) Announcement to CE, CE route calculation, add these routes to the global routing table, such. LDP distribution label:First, the PE1 global route table contains a direct connection route of 1.1.1.1/32, and then LDP distributes tags for all IGP routes. Because it is the last hop, a special label 3 is distributed. (Please note that, the table I wrote above cannot be seen in the MPLS Forwarding Table,Because label 3 will not be added to MPLS, it will not

efficient approach is to use a data structure that is efficient in searching performance instead of sliding windows.LZ77 has a better compression ratio than Huffman coding, but LZ77 takes a considerable amount of time during the compression process. If the forward buffer contains a, B, and D then the buffer contains the phrase {(A), (a,b) (A,B,D)}If the sliding

, in addition to skipping the cost of traversal, also skips understanding the process of compressing these compressed blocks, thus saving the CPU.Merging with BitsetBitset is a very intuitive data structure that corresponds to posting list such as:[1,3,4,7,10]The corresponding Bitset is:[1,0,1,1,0,0,1,0,0,1]Each document is sorted by the document ID and corresponds to one bit. The Bitset itself has the feature of
