GSR: Receive Access Control Lists

Tags:
switching

Overview Data received by a Gigabit Switch Router (GSR) can be divided into two broad categories. First one is traffic that passes through the router via the forwarding path and second traffic that must be sent via the receive path to the GRP for further analysis. " In normal operations, the vast majority of traffic simply flows through a GSR en route to other destinations. This paper describes a new security feature called receive Access Control Lists (rACLs) and presents recommendations and guidelines for rACL deployments. Receive ACLs are used to increase security on Cisco 12000 routers by protecting the router's GRP from unnecessary and potentially nefarious traffic.

MPLS: The icing on the networking cake?

Iain Stevenson, networking analyst at Ovum, put it like this: "MPLS is a mechanism for labelling traffic flows to define a path through a complex network. The development of 10 Gigabit Ethernet is more impressive," he said.

VoIP primer: How it works - and what the jargon means

An IP packet is formed when a router chops up a stream of digital information into manageable chunks. The router then places two addresses in the packet's header field - one for the destination, one for the originating device.
