多租户网络需要额外考虑:支持虚拟网络的快速部署和拆除(rapid deployment and teardown)。 传统网络设计的扩展方式:scale-in(垂直扩展),即通过更换性能更高的设备实现。缺点: 高性能设备特别贵 这些设备大部分都是两方冗余(two-way redundancy),存在同时挂掉的风险,可用性 不是足够高 发生故障时,故障范围特别大(尤其...
The Border Gateway Protocol (BGP) has emerged as the most popular routing protocol for the data center, yet many network operators and data center administrators are concerned about its complexity. This guide peels away the mystique to reveal a simple yet sophisticated protocol. It explores the th...
1 数据中心网络绪论 本章介绍在给定应用需求和预期规模的前提下,如何为现代数据中心设计网络(network design of a modern data center network)。 和十年前相比,现代数据中心规模更大,网络部署速度要求更快(秒级而不是天级)。这显 著影响了网络的设计和部署。 BGP(Border Gateway Protocol):边界网关协议。 过去的...

BGP in the Data CenterDinesh Dutt
BGP is an increasingly popular protocol for use in the data center as it lends itself well to the rich interconnections in a Clos topology.RFC 7938provides further details about using BGP in the data center. How Does BGP Work? BGP directs packets between autonomous systems (AS), which are ...
RFC 7938 provides further details about using BGP in the data center. How Does BGP Work? BGP directs packets between autonomous systems (AS), which are a set of routers under a common administration. Each router maintains a routing table that controls how the switch forwards packets. The BGP...
ping <the IP address of a client in the data center> 前の図に示すように、ECS 1が応答を受信できる場合、データセンターとVPCが接続されます。 ステップ2: Express Connect回路による専用接続の暗号化 データセンターがVPCに接続された後、カスタマーゲートウェイデバイス...
It is critical to understand the application traffic profile in the data center. Suppose you attach big data platforms to your border leaf device, and replication of multiple terabytes of data starts between the servers. At the same time, your data center streams video content to users in the...
Indicates the carried IPv6 unreachable route information. The Next_Hop attribute in BGP4+ is in the format of an IPv6 address, which can be either a globally unique IPv6 address or a next hop link-local address. Using multiple protocol extensions of BGP, BGP4+ is applicable to IPv6 networ...
