Border Gateway Protocol(BGP) is inter-autonomous system（ ）protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest （ ）count is not the preferred route. For example， we may not want a packet through an not secure even though it is the shortest route. Also， distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without actually defining the path that leads to that（ ）.A router that receives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link（ ）routing is also not a good candidate for inter-autonomous system routing because an Internet is usually too big for this routing method. To use link state routing for the whole internet would require each router to have a huge link state database. It would also take a long time for each router to calculate its rousting （ ）using the Dijkstra algorism.

Network security is the protection of the underlying networking infrastructure from ( )access, misuse, or theft, It involves creating a secure infrastructure for devices, users and applications to work in a ( ) manner. Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements ( ) and controls. Authorized users gain access to network resources. A ( ) is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. A virtual (作答此空) network encrypts the connection from an endpoint to a network, often over the internet. Typically a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.
