Ingress, egress, and regress are legal terms referring respectively to entering, leaving, and returning to a property or country. The term also refers to the rights of a person (such as a lessee ) to do so as regards a specific property.
Egress may refer to: Data egress, data leaving a network in transit to an external location; Egress, the right of a person to leave a property; Egress (signal leakage), the passage of electromagnetic fields through the shield of a coaxial cable; Egress filtering, in computer networking, monitoring and/or restricting the flow of outbound information
To account for data path delays, the gPTP protocol measures the frame residence time within each bridge (the time required for receiving, processing, queuing and transmission of timing information from the ingress to egress ports), and the link latency of each hop (a propagation delay between two adjacent bridges).
Egress filtering may require policy changes and administrative work whenever a new application requires external network access. For this reason, egress filtering is an uncommon feature on consumer and very small business networks. PCI DSS requires outbound filtering to be in place on any server in the cardholder's environment.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway , [ a ] motorway , [ b ] and expressway .
Ingress (signal leakage), the passage of an outside signal into a coaxial cable; Ingress filtering, a computer network packet filtering technique; Ingress protection rating, a protection level that electrical appliances provide against intrusion of physical objects; Ingress router, a source label switch router
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.
In ingress filtering, packets coming into the network are filtered if the network sending it should not send packets from the originating IP address(es). If the end host is a stub network or host, the router needs to filter all IP packets that have, as the source IP, private addresses (RFC 1918), bogon addresses or addresses that do not have ...
