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
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.
RPR works on a concept of dual counter rotating rings called ringlets. These ringlets are set up by creating RPR stations at nodes where traffic is supposed to drop, per flow (a flow is the ingress and egress of data traffic). RPR uses Media Access Control protocol (MAC) messages to direct the traffic, which can use either ringlet of the ring ...
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.
Data link layer processing and extracting the packet; Decoding the packet header; Looking up the destination address in the packet header; Analyzing other fields in the packet; Sending the packet through the "fabric" interconnecting the ingress and egress interfaces; Processing and data link encapsulation at the egress interface
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
Ingress filtering for multihomed routers will accept the packet if there is a route back to its source address from any interface on the router. For this type of filtering, the router may also maintain an adjacency table , also organized for fast lookup, that keeps track of the router interface addresses that are on all directly connected routers.
