SRH is a new type of IPv6 Routing Extension Header and it includes SRv6 SIDs. It may include a Segment List encoded as an IPv6 Address. It is not an exact IPv6 address. You may think like it is just a format and we will call it SRv6 SID. Format is IPv6 address but in …
As you know, Segment Routing can be applied to the IPv6 data plane by using routing extension headers. SRH is a new type of IPv6 Routing Extension Header which includes one or more SRv6 SID inside. These SRv6 SIDs have locator and function fields and they used for traffic engineering, vpn services, service function chaining …
Segment Routing (SR) is a new source routing paradigm which means that the source can define the path that the packet will take. Although there are some other ways to do this “Source Routing”, Segment Routing is candidate to be easiest way. It is possible to run Segment Routing on MPLS Data and IPv6 Data …
MLAG can be used at various places in the network to eliminate bottlenecks and provide resiliency, including the spine layer and leaf layer. But the most common use case for M-LAG is using this feature at the Leaf layer. At the leaf of the network, servers with multiple interfaces connect to the switches using NIC …
In the new generation data center networking design, we have “clos” topologies which is based on network–based spine-and-leaf architecture. CLOS topology basically have 2 tier, Spine (Core) and Leaf (Access). Every leaf switch is connected to all Spine switches. The spine layer is the backbone of the network and is responsible for interconnecting all leaf …
With the rapid evolution of SDN, industry have started to separate networks as Underlay and Overlay. An overlay is a virtual network that is built on top of an underlying network infrastructure, underlay. It is the underlying network responsibility to deliver packets across networks. Here are summary of Underlay and its characteristics; – Physical infrastructure which …
A new data center design called the Clos network–based spine-and-leaf architecture was developed to overcome these limitations. This architecture has been proven to deliver the high-bandwidth, low-latency, non-blocked links etc. CLOS topology basically have 2 tier, Spine (Core) and Leaf (Access). Every leaf switch is connected to all Spine switches. The spine layer is the …
In traditional data center networking the architecture consists of core routers, aggregation routers (sometimes called distribution routers), and access switches. Between the aggregation routers and access switches, Spanning Tree Protocol is used to build a loop-free topology for the Layer 2 part of network. This approach has several drawbacks including loops, unused links, unpredictable delays …
