An egress router is a label switch router that is an end point (drain) for a given label-switched path (LSP). 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 ...
Ingress router. An ingress router is a label switch router that is a starting point (source) for a given label-switched path (LSP). An ingress router may be an egress router or an intermediate router for any other LSP (s). Hence the role of ingress and egress routers is LSP specific. Usually, the MPLS label is attached with an IP packet at the ...
Clos network. In the field of telecommunications, a Clos network is a kind of multistage circuit-switching network which represents a theoretical idealization of practical, multistage switching systems. It was invented by Edson Erwin [1] in 1938 and first formalized by the American [2] engineer Charles Clos [3] in 1952.
Egress filtering. In computer networking, egress filtering is the practice of monitoring and potentially restricting the flow of information outbound from one network to another. Typically, it is information from a private TCP/IP computer network to the Internet that is controlled. TCP/IP packets that are being sent out of the internal network ...
Access control. A sailor checks an identification card (ID) before allowing a vehicle to enter a military installation. In physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of accessing may mean consuming ...
Virtual output queueing. Virtual output queueing ( VOQ) is a technique used in certain network switch architectures where, rather than keeping all traffic in a single queue, separate queues are maintained for each possible output location. It addresses a common problem known as head-of-line blocking. [1]
IP address spoofing involving the use of a trusted IP address can be used by network intruders to overcome network security measures, such as authentication based on IP addresses. This type of attack is most effective where trust relationships exist between machines. For example, it is common on some corporate networks to have internal systems ...
