Brocade-HyperEdge -The effortless IP networks

  1. 1. POSITIONINGPAPERThe Effortless Network:HyperEdge Technology for the Campus LANThe Brocade One® strategy represents a smooth transition to a world where information and applicationsreside anywhere in the cloud. Customers use the campus LAN as the portal to the data center cloud, andThe Effortless Network™ is the Brocade vision for the future of the campus LAN. Based on the foundationof Brocade® HyperEdge™ technology, The Effortless Network simplifies network architecture andautomates configuration and management tasks, while providing enterprise-grade flexibility, security, andscalability for wired and wireless access. Unlike competitive approaches, The Effortless Network avoids thetrap of over-engineered, over-priced, and hard-to-manage campus networks. It is designed to meet therequirements of the most demanding applications with a network that keeps running, no matter what.New Applications Add New StressesVirtual Desktop Infrastructure (VDI) leverages servervirtualization to reduce the cost and complexity ofdesktop application support, application upgrades,data management, and data security. While VDIaddresses desktop application problems includingupgrades, patching, and security of desktop data, italso creates new challenges for the campus LAN.User mouse clicks, typing, and screen refresheshave to move from the local device to the virtualmachine hosting the desktop, and back again. Theimpact in the campus is higher bandwidth, lowerlatency, and always-up availability.As end-user devices increase performance at thespeed of Moore’s Law, user expectations increase just as fast. Nowhere is the expectation gap moreevident than with video. Today, users expect real-time access to streaming video for corporate training,executive briefings, and even when conducting meetings with remote customers. This “video-on-demand”expectation requires the campus network to deliver higher bandwidth with low latency and jitter.Enterprises are experiencing a historic transition in how employees communicate. Previously, voice, e-mail,instant messaging, and video conferencing were deployed with separate applications, used differentdevices, and often had independent networks. Today, Unified Communications (UC) brings all forms ofcommunication to a single device—a desktop/laptop computer, tablet, iPad, or smartphone—deliveringreal-time collaboration. Human collaboration is dynamic. For example, a low-bandwidth text message caninstantly transform into a shared desktop with joint editing of documents, and—with a mouse click—canexpand to a video chat before disappearing again at the end of the collaboration. The campus network hasto scale, ensure consistent security policies, and provide low latency and jitter while maintainingcontinuous uptime.
  2. 2. The explosion of smartphones, tablet computers, and iPads sets a user expectation that access to thedata, applications, and social networks they rely on in their personal lives will be available when they are atwork. Bring Your Own Device (BYOD) has a positive impact on IT budgets when users purchase andmaintain their own devices, yet it creates concerns about securing wireless access to sensitive corporatedata. User expectations of seamless access require consistently applied security policies across both wiredand wireless LAN segments.Figure 1. Impact of BYOD on campus LAN.Friction Points: Business Expectations Confront Campus RealitiesEvery network in the enterprise, whether it is the data center or the campus, must be designed to meetbusiness expectations that are balanced with technology choices. This has not been easy, with IT budgetsshrinking while applications, data, and user devices have continued to grow rapidly—even during therecent recession.The cost of running the campus network isout of control in many organizations. Gartnerestimates that companies spend 17 percentof their total IT budget (CapEx plus OpEx) ontheir networks. In 2011, more than half ofthe operating expense was devoted tomaintaining the campus network. Gartneralso found that companies who had a singlevendor procurement strategy for the campusincurred a 25 percent premium in total costof ownership over a five-year period. Thisadds up to an average cost of $1,400 per person per year for campus networks—clearly a majorinvestment. For this reason, focused actions that reduce the cost of the campus LAN are a top strategicobjective at many companies.The Effortless Network: HyperEdge Technology for the Campus LAN 2 of 8
  3. 3. A survey of Fortune 1000 enterprise network administrators (taken by InfoPro) identified the following topfour pain points for companies operating a campus network:1. Keeping up with technology2. Capacity planning3. Reliability and performance4. Managing growthThe root cause of this pain is complexity. Campus networks originally provided a connection from desktopcomputers to file/print servers or connected desktop clients to servers hosting back office applications.Today, Unified Communications, virtual desktop infrastructure, streaming video, and Web 2.0 applicationsclearly create complex traffic flows. The campus LAN has to ensure device access is secure, as well ashaving to scale with the increased use of rich media, including peer-to-peer video conferences and videochat. It also has to handle the wide range of data streams created when collaborating with UnifiedCommunications applications.Increasingly, work happens at any time and any place an employee chooses. It is common for employeesto use several devices during the day: a desktop or laptop computer, a tablet computer, an iPad, and asmartphone. Employees expect the freedom to choose the device that best meets their needs withunfettered access to applications and data. This is causing an explosion in wireless traffic in the campus,which creates new traffic patterns while requiring more bandwidth. To keep up, administrators needunified management across wired and wireless segments. In particular, security policies need to beconsistent and simple to administer.Where Is the Innovation?Clearly, there is a need for innovation in the campusnetwork. New applications, device mobility, and the positive “There have been fewimpact on the bottom line of seamless collaboration substantial changes to thebetween workers, suppliers, and customers is happening [enterprise] networkingmuch more quickly than the traditional campus network is vendors’ approaches in theable to evolve. last 20 years.”Gartner points out, however, that for the past 20 years there —Gartnerhas been little innovation in the enterprise network. Venturecapital investment—a measure of innovation—has drasticallydropped from a high in 2000 of $11 billion to less than $1billion in 2011. Combined with the fact that the leaders in campus networking, both at the high and lowend of the market, have not made significant investments beyond incremental “speed and feed”enhancements, it becomes clear why innovation has stalled in the campus LAN.Building The Effortless NetworkAs Brocade has considered today’s campus network and the “Don’t assume that currentimpact of new applications and business demands, it hasbecome clear that solving emerging problems using old architectural approaches areassumptions is an inadequate approach.

  4. 4. Brocade HyperEdge TechnologyBrocade HyperEdge technology provides consolidated management and mix-and-match stacking on thecampus LAN, so that you can operate at the speed of business, take risk and effort out of networkadministration, and have confidence in a network that “just works.” HyperEdge technology is designed towork with the Brocade ICX® Series of campus switches.Consolidated ManagementCampus networks extend between buildings, across multiplefloors, and—with wireless access points—span outdoor aswell as indoor spaces. With traditional networks, adding aswitch, changing a network policy, or adding another userdevice requires manual changes to multiple configurationsettings in many switches, routers, access points, andcontrollers. The opportunity to make a mistake, not tomention the time and effort involved, is why operating costsand complexity in the campus network have gotten outof control.With HyperEdge technology, multiple switches can bepooled together and managed as a single entity.Administrators can apply all configuration changes andpolicy settings to every switch assigned to the pool from asingle point of management.When a new switch is added to the pool, HyperEdge HyperEdge Technologytechnology discovers the switch and its capabilities. Existing Consolidated Managementconfiguration and policy settings are automatically appliedwithout operator intervention. The consolidated management of switch pools across the campus providedby HyperEdge technology makes switch configuration simple, automatic, and immediate. This providesassurance that security and access control policies are consistently applied as new switches are added.In many campus networks, switch firmware upgrades create significant extra work, requiring time-consuming manual changes to each switch. Consolidated management includes the ability to apply a newfirmware release automatically to every switch in a pool.Finally, as traffic patterns become more complex and devices grow, tools that simplify traffic monitoringand management are critical for a high-quality user experience. An important capability built into theBrocade campus LAN products supported by HyperEdge technology is the open standard sFlowprotocol. With sFlow, administrators have immediate access to traffic statistics. They can see an overviewof the entire campus network and zoom into a single virtual machine hosting a VDI application or UCserver. sFlow support across a set of switches pooled together with HyperEdge technology meansadministrators can continue to use their favorite sFlow monitoring applications with the Brocade family ofcampus switches.The Effortless Network: HyperEdge Technology for the Campus LAN 4 of 8
  5. 5. Mix-and-Match StackingSwitch stacking is a common method of scalingconnectivity and bandwidth at a lower cost than with achassis switch. Stacking connects multiple switchestogether using dedicated stacking ports on eachswitch. However, current stacking methods also haverestrictions. Flexibility is lost, as all switches in a stackmust have the same hardware configuration andfeatures enabled, including expensive Layer 3protocols. Finally, investment protection is limited,because upgrading switch hardware requires allswitches in the stack to be replaced, while addingpremium features means all switches have to HyperEdge Technologybe upgraded. Mix-and-Match StackingHyperEdge mix-and-match switch stacking eliminatesall these drawbacks and lowers first cost, while improving scalability and flexibility. HyperEdge switchingstacks can include a mix of Layer 2 and premium Layer 3 switches in the same stack. All switches sharethe premium Layer 3 protocols without requiring every switch to be upgraded or replaced. A singleadvanced Layer 3 switch (or two switches, for high availability) can be added to a stack at any time. Allswitches can send traffic to the Layer 3 capable switches, dramatically reducing the cost of the stack.HyperEdge mix-and-match stacking provides all the benefits of chassis switch architecture. For example, ina chassis, it is easy to combine a high-performance routing card with high-density Layer 2 Ethernet cards.For the first time, HyperEdge mix-and-match stacking offers the same benefits in a highly cost-effectiveswitch stack. More important, as new campus products become available with advanced services andfeatures, they can be added to existing stacks without replacing or upgrading the other switches in thestack. This unique innovation delivers long awaited investment protection, increased operational flexibility,and significant first-cost savings to the campus LAN.The Effortless Network: HyperEdge Technology for the Campus LAN 5 of 8
