Another protocol for implementing vpn is ipsec. To be precise, ipsec is a framework composed of multiple protocols. Its implementation can be divided into the following four steps:
1. implement data stream filtering control (control by acl)
2. Security proposal (implementing the working mode, selecting the security protocol, verifying the algorithm, and selecting the consistency of the encryption algorithm if the esp protocol is used)
3. Create a security policy (acl + security proposal + ike ne

In general, the recursive algorithm in the actual implementation of the computer contains a lot of repetitive calculation, so the efficiency is lower the second question
The breadth-first search for graphs is similar to the sequence traversal of a tree, which requires the help of the third problem of the queue

Requirements include the quantified and documented needs and expectations of the initiator, customer, and other stakeholders. These requirements should be identified, analyzed, and documented in sufficient detail, included in the scope benchmark, and measured after the project starts to run. Requirements will become the basis of the work breakdown structure (WBS. Demand is also the basis of cost, progress and quality planning, and sometimes the basis of procurement.
