Accordingly, one of the most crucial functions performed by the Internet is the routing of traffic ingress nodes to egress nodes. Ultimately, it is the performance of the network as seen by network services that is truly paramount. This crucial function should be considered throughout the development of engineering mechanisms and policies.
VACLs may be used in similar fashion to a SPAN port or network tap, as a way to replicate computer network data that is coming into and leaving from a computer or a network. This is useful if you want to monitor traffic. Often, this configuration is used to facilitate data loss prevention (DLP) or network-based intrusion prevention systems. [2]
In computer networking, network traffic control is the process of managing, controlling or reducing the network traffic, particularly Internet bandwidth, e.g. by the network scheduler. [1] It is used by network administrators, to reduce congestion, latency and packet loss. This is part of bandwidth management.
802.1X-2001 defines two logical port entities for an authenticated port—the "controlled port" and the "uncontrolled port". The controlled port is manipulated by the 802.1X PAE (Port Access Entity) to allow (in the authorized state) or prevent (in the unauthorized state) network traffic ingress and egress to/from the controlled port.
Packets that do not meet security policies are not allowed to leave – they are denied "egress". [1] Egress filtering helps ensure that unauthorized or malicious traffic never leaves the internal network. In a corporate network, typical recommendations are that all traffic except that emerging from a select set of servers would be denied egress.
An egress router may be an ingress router or an intermediate router for any other LSP(s). Hence the role of egress and ingress routers is LSP specific. Usually, the MPLS label is attached with an IP packet at the ingress router and removed at the egress router, whereas label swapping is performed on the intermediate routers.
Individual MAC frames of unicast traffic from an Ethernet-attached device that are received at the SPBM edge are encapsulated in a PBB IEEE 802.1ah header and then traverse the IEEE 802.1aq network unchanged until they are stripped of the encapsulation as they egress back to the non-participating attached network at the far side of the ...
This control can be accomplished in many ways and for many reasons; however traffic shaping is always achieved by delaying packets. Traffic shaping is commonly applied at the network edges to control traffic entering the network, but can also be applied by the traffic source (for example, computer or network card [6]) or by an element in the ...
