WHY YOU SHOULD PLACE LESS EMPHASIS ON MPLS TRAFFIC ENGINEERING
If I input MPLS traffic engineering on any search engines, I will find about 100 articles on the internet providing the same explanations about MPLS traffic engineering. But unfortunately, nobody ask these questions: do I really need it? What are the reasons behind the implementation of MPLS Traffic Engineering? Would it worth the time and energy […]

MANET: Mobile Ad Hoc Networks
The MANET stands for mobile ad hoc network; in practice, the term generally applies to ad hoc wireless networks of sufficient complexity that some internal routing mechanism is needed to enable full connectivity. The term mesh network is also used for MANETs. MANET nodes communicate by radio signals with a finite range, as in the Figure – […]

What is Routing Loop and How is Routing Loop Prevented ?
A potential problem to packet forwarding is a possibility of a routing loop. It occurs because some packets circulate endlessly due to the set of entries in the forwarding table. Figure – 1 For example, in the Figure -1 we would have a routing loop if, for (nonexistent) destination G, A forwarded to B, B forwarded to D, D forwarded to E, E forwarded to C, and C […]

IS-IS Design: Avoiding Traffic Blackholing
IS-IS, a link state routing protocol, requires careful attention during network design in order to avoid traffic blackholing. In the topology below, IS-IS routing protocol is used. The primary path is the blue link. Using IS-IS, the overload bit signals the BGP. If the overload bit is set on Router B, Router A does not use router B as […]

Datacenter Design: Shortest Path Bridging
IEEE 802.1aq Shortest Path Bridging (SPB) uses IS-IS as an underlying control plane mechanism that allows all the links in the topology to be active. In sum, it supports layer 2 multipath. SPB is used in the datacenter; however, it can also be used in the local area network. In this article, Figure-1 will be used to […]

Dual Carrier MPLS VPN Design
For the purpose of high availability, critical locations of company A – a customer of VPN service provider – is connected to two different carriers. However, this connectivity requires an important design consideration. Figure-1 In the network design shown above, customer AS 64512 is connected to two different providers: AS100 and AS200. Since this site is critical to the […]

OSPF in a Full-Mesh Topology Design
Flooding in full-mesh topology is a big concern for network-design experts, especially in large-scale OSPF deployments. When the link or node fails in an OSPF network, failure information is flooded everywhere in the same area. If Flat OSPF network design is used, then the problem gets bigger. Each router receives at least one copy of the new information from […]
