mechanisms, and one of the keys to promoting WiMAX technology is to provide End-to-end QoS guarantees for multimedia services such as voice and video. To solve this problem, we first need each network unit to effectively manage the local resources to provide the End-to-end service load to meet the business needs, and at the same time, the QoS parameter mapping of the application layer will load the corresponding attribute parameter. WiMAX network hosting consists of two parts: wireless bearer a
Network designers use firewalls to protect networks from unauthorized use. Consider a lock on a door to a class inside a building. The lock allows only authorized users with a key or access card to pass through the door. Similarly, a firewall filters unauthorized or potentially dangerous packets from entering the network. On a Cisco router, you can configure a simple firewall that provides basic traffic filtering capabilities using ACLs. Administrator
Label:Access Control List An ACL is a sequential list of permit or DENY statements this apply to addresses or Upper-layer protocols. ACLs provide a powerful-to-control traffic into and out of a network. ACLs can configured for all routed network protocols. IP ACL operationWhen configured, ACLs perform the following tasks:
Limit network traffic to increase

[Lab7] AclAccess control lists are referred to as ACLs, which use packet filtering technology to read third and fourth headers on routerssuch as source address, destination address, source port, destination port, etc., filter packets according to pre-defined rules,So as to achieve the purpose of access control. There are many kinds of ACLs, and different kinds of ACLs

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging the server is not allowed. In this case, an extended ACL is needed to replace the standard ACL application, and in actual application

Default encoding for JavaFor example, String.getbytes () calls the default encoding, the process is as follows:The default encoding is obtained first: String CSN = Charset.defaultcharset (). Name ();Use if the default encoding has an exception: "Iso-8859-1"So how does the default encoding get? Read the following source code as followsThe default charset is determined during virtual-machine startup and typically depends upon the locale and charset of t
