What is the meaning origin of the terms north-south and east-west . . . Generally speaking, "east-west" traffic refers to traffic within a data center -- i e server to server traffic "North-south" traffic is client to server traffic, between the data center and the rest of the network (anything outside the data center)
How to Balance SPAN Traffic from Redundant Switches So we are wanting to deploy an IDS device to capture EAST-WEST traffic in a LAN The actual topology is more complicated but our issue boils down to this: We are attempting to configure SPAN sessions from the many VLANS to the ports connected to the IDS
protocol theory - What is 1 Erlang for network data traffic . . . Erlang's definition does not apply generically to data traffic, because there is no standard definition of a "call" in data traffic, nor is there call-blocking as you would find in a fully-utilized Circuit-Switched link If we make some assumptions about the data network and the type of calls, we can shoe-horn the measurement into a data network
Same subnet, two locations, BGP. Can it be done? We have an east coast and west coast location Each of these locations has a VPN connection to a common 3rd party location via VPN The subnet of this 3rd party is 10 5 5 0 24 We have a number of locations throughout the United States all connected through an MPLS network I would like those locations to use either the east or west coast VPN
what is the industry standard meaning of flat network There is no official definition, and it means different things to different people In general, the term, "flat network," means that the network isn't hierarchical (network engineer definition), or it is not security segmented (security engineer definition)
Beginners Guide to VLAN with Netgear Ubiquiti HW VLAN101? You said you need some east west (vlan to vlan) communication blocked Do you have any rules on the USG preventing that now? Make sure the interface going to your USG and to your APs are setup as trunks and are configured to pass the tagged traffic (have the VLANs configured on them)
Advantages to BGP peering over VPN - Network Engineering Stack Exchange This kind of trick was used by certain ISP's abusing peering relationships - provider A peers at two points (let's say east and west coast of the US) Provider A builds a tunnel between his peering nodes across B's network and B is suddenly unwillingly providing free cross-country bandwidth
Tips on analyzing traceroute readings - Network Engineering Stack Exchange 1 Understand the difference between traffic going TO a router vs THROUGH a router Each line in a traceroute represents the time in milliseconds (ms) it took for that particular router to respond to the initiating client with a TTL Expired message Each hop is usually tested 3 times, so you get 3 different values
